Black cumin seed oil and curcumin in turmeric: Immunity and inflammation help?

What can seniors do to help balance their immune and inflammatory responses? You might look into researching various anti-inflammatory oils such as black cumin seed oil, used in the Middle East for centuries. Currently researchers are finding it helpful. Scientists have determined that black cumin seeds contain a broad spectrum of active compounds that provide powerful and wide-ranging immune support and promote healthy inflammatory response.

A number of biological factors contribute to the body’s normal inflammatory activity, including cell-signaling chemicals and hormone-like messengers. In a series of scientific studies, black cumin seed oil has been shown to support the normal effectiveness of these inflammatory factors.

Supporting your immune system defenses

What exactly black cumin seed oil does in the healthy immune system that’s aging is to support the optimal function of immune defense so that your own immune system can orchestrate the activity of macrophages and helper T-cells. These cells work together to identify and destroy dangerous microbes and abnormal cells. Black cumin seed oil research also focuses on how the oil can support the optimal function of immune system defensive activities.

What the black cumin seed oil actually works on are the immune factors and also the inflammatory factors. Black Cumin Seed Oil supports a healthy immune system’which is increasingly important as we age’and facilitates a healthy inflammatory response. Another similar nutrient is curcumin, which comes from turmeric. Curcumin possesses some of the properties of black cumin seed oil. Some people take a little of both.

Turmeric: Health effects studied

What substance is in turmeric and curry powder that so many doctors are touting as a possible memory enhancer focused on perhaps helping to prevent Alzheimer’s disease? It’s curcumin.

Should you take a dash of black pepper and a dash of turmeric in a beverage or in food before going on a stroll or doing any type of exercise for the energy benefits? Black pepper helps your body absorb turmeric. See the article, 10 of the Most Powerful Herbs & Spices food4mythoughts.com. And check out Dr. Weil’s article, Curcumin or Turmeric?

Who’s studying cucurmin, an ingredient from turmeric, a spice to see what health benefits it may have, especially in relation to see whether cucurmin and/or turmeric has any type of prevention ability on Alzheimer’s or other dementia types? There have been studies at UCLA. In the Sacramento and Davis regional area, check out the local UC Davis article on cucurmin, found in turmeric, RSC Article Template (Version 3.0)[PDF].

You can buy turmeric in any supermarket, including in larger packages, you can buy turmeric at any of the ethnic Indian grocery stores in Sacramento. Also, you can order cucurmin, the ingredient in turmeric being studied, from most health food stores or online for example, from the Life Extension Foundation. Check out the October, 2007 article by Life Extension Foundation’s magazine titled, Novel Turmeric Compound Delivers Much More Curcumin to the Blood.

The University of California, Davis in the Sacramento-Davis regional area studies the effects turmeric or the ingredient found in turmeric, curcumin, has on protecting the brain from too much damage by accumulating amounts of copper and iron, which may or may not be linked to developing neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease. Check out the site, UC Davis Alzheimer’s Disease Center.

Can turmeric help prevent Alzheimer’s disease by cutting amyloid plaque in your brain?

On the Dr. Oz show, a guest physician explained how cucurmin, an ingredient in turmeric and curry might work to reverse amyloid plaque in the brain which may lead to Alzheimer’s. Also see the article, Turmeric and Curcumin Show Major Health Benefits .

The main point is that turmeric and curry powder were suggested by Dr. Oz and his physician guest in a rerun shown on TV channel included a segment on how to lower the risk of Alzheimer’s disease as one more spice in the fight to prevent Alzheimers.

Curcumin is the active ingredient in turmeric, a spice in the ginger family used in cooking and for medical purposes. The Dr. Oz show today also revealed that some students on a curry/turmeric ethnic diet similar to what’s eaten as a staple in India performed better on memory tests than students not eating a diet emphasizing curry and turmeric-spiced foods.

Turmeric is used by doctors and healthcare providers in Asian cultures

Curcumin is an ingredient in turmeric that sometimes is taken as a supplment because it’s thought to have anti-inflammatory, antioxidant, and antiviral properties. In India, for example, you can buy band-aids coated with turmeric, where it also is used as a topical disinfectant as well as a spice put in food.

If you take other foods, drugs, or supplements that are considered blood thinners (like fish oil) or a daily aspirin, be aware that curcumin can raise the risk of uncontrolled bleeding if taken with aspirin, blood thinners (heparin), nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, and anti-platelet medicines.

According to a Tufts University, Boston, MA study funded by a grant from the United States Department of Agriculture and released to the media on May 18, 2009, curcumin, the major polyphenol found in turmeric, appears to reduce weight gain in mice and suppress the growth of fat tissue in mice and cell models. Can it also stop humans from gaining weight?

Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (USDA HNRCA) studied mice fed high fat diets supplemented with curcumin and cell cultures incubated with curcumin. Asma Ejaz, a graduate student who worked on this project also received a scholarship grant from the Higher Education Commission of Pakistan. You can read the study, Ejaz A, Wu, D, Kwan P, and Meydani M. Journal of Nutrition. May 2009; 139 (5): 1042-1048. “Curcumin Inhibits Adipogenesis in 3T3-L1 Adipocytes and Angiogenesis and Obesity in C57/BL Mice. 919-925.”

Turmeric and an ingredient in it, curcumin has been studied in the past in relation to preventing Alzheimer’s disease. Now this new study focuses on preventing weight gain. According to a May 18th 2009 Tufts University press release, “Weight gain is the result of the growth and expansion of fat tissue, which cannot happen unless new blood vessels form, a process known as angiogenesis.” said senior author Mohsen Meydani, DVM, PhD, director of the Vascular Biology Laboratory at the USDA HNRCA.

“Based on our data, curcumin appears to suppress angiogenic activity in the fat tissue of mice fed high fat diets.” Meydani continued in the news release, “It is important to note, we don’t know whether these results can be replicated in humans because, to our knowledge, no studies have been done.”

Turmeric is known for providing flavor to curry

One of its components is curcumin, a type of phytochemical known as a polyphenol. Research findings suggest that phytochemicals, which are the chemicals found in plants, appear to help prevent disease. As the bioactive component of turmeric, curcumin is readily absorbed for use by the body.

Meydani and colleagues studied mice fed high fat diets for 12 weeks. The high fat diet of one group was supplemented with 500 mg of curcumin/ kg diet; the other group consumed no curcumin. Both groups ate the same amount of food, indicating curcumin did not affect appetite, but mice fed the curcumin supplemented diet did not gain as much weight as mice that were not fed curcumin.

“Curcumin appeared to be responsible for total lower body fat in the group that received supplementation,” said Meydani, who is also a professor at the Friedman School of Nutrition Science and Policy at Tufts. “In those mice, we observed a suppression of microvessel density in fat tissue, a sign of less blood vessel growth and thus less expansion of fat. We also found lower blood cholesterol levels and fat in the liver of those mice. In general, angiogenesis and an accumulation of lipids in fat cells contribute to fat tissue growth.”

Writing in the May 2009 issue of the Journal of Nutrition, the authors note similar results in cell cultures. Additionally, curcumin appeared to interfere with expression of two genes, which contributed to angiogenesis progression in both cell and rodent models.

“Again, based on this data, we have no way of telling whether curcumin could prevent fat tissue growth in humans.” Meydani said. “The mechanism or mechanisms by which curcumin appears to affect fat tissue must be investigated in a randomized, clinical trial involving humans.”

Turmeric and Alzheimer’s Prevention Research

Black cumin seed oil and curcumin in turmeric: Immunity and inflammation help? - National Senior Health

What about turmeric or curcumin for preventing Alzheimer’s if you’re not able to fight the environmental pollution where you have to live? Curcumin is an ingredient naturally found in turmeric.

According to a different study, published in August 2009 in the Journal of Alzheimer’s Disease, and reported in a Lee Swanson Research Update titled, “Vitamin D-Curcumin Combo Offers Brain Health Potential,” A combination of vitamin D3 and curcumin, from turmeric, may boost the immune system and help it clear the protein plaques linked to Alzheimer’s, notes the August 2009 Journal of Alzheimer’s Disease study.

The Lee Swanson Research Update reported that the data, published in the Journal of Alzheimer’s Disease, may lead to new approaches in preventing Alzheimer’s by using vitamin D3 alone or in combination with natural or synthetic curcumin to boost the immune system in protecting the brain against beta-amyloid. Curcumin is found in and/or extracted from turmeric.

In the curcumin study, there’s hope for prevention of Alzheimer’s from turmeric and/or cucurmin, an extract from turmeric. “We hope that vitamin D3 and curcumin, both naturally occurring nutrients, may offer new preventive and treatment possibilities for Alzheimer’s disease,” said Dr. Milan Fiala from the University of California Los Angeles (UCLA).

Monocyte cells, which transform into macrophages and in turn boost the immune system, were isolated from blood samples taken from nine Alzheimer’s patients, one patient with mild cognitive impairment and three healthy control subjects.

The macrophages were then incubated with beta-amyloid, vitamin D3 and natural or synthetic curcumin. The naturally occurring curcumin was found to be poorly absorbed, making it less effective than the synthetic curcuminoids, said the researchers. “We think some of the novel synthetic compounds will get around the shortcomings of curcumin and improve the therapeutic efficacy,” said John Cashman of the Human BioMolecular Research Institute.

What curcumin enhances

The curcuminoids were found to enhance binding of beta-amyloid to macrophages, and that vitamin D could strongly stimulate the uptake and absorption of beta-amyloid in macrophages in most of the patients.

Previous research by the same scientists found that there are two types of Alzheimer’s patients: Type I patients, who respond positively to curcuminoids, and Type II patients, who do not. This depends on the genes MGAT III and TLR-3 that are associated with the immune system’s ability to better ingest beta-amyloid, the researchers said.

“Since vitamin D and curcumin work differently with the immune system, we may find that a combination of the two or each used alone may be more effective’depending on the individual patient,” said Fiala.

The UCLA researchers stressed that the research is still in its early stages and that no doses of either compound can be recommended at this point. They noted that larger vitamin D and curcumin studies with more patients are planned. Read the study in the Journal of Alzheimer’s Disease 17(3):703-717

Is it true that research is beginning to show that an ingredient, a phytochemical, in turmeric called curcumin, actually reverses, slows, or even helps to prevent early stage Alzheimer’s disease? Is the reported low rate of Alzheimers and some other dementia types in India due to the daily of addition of a small amount of turmeric and curry spices in the average diet?

On the other hand, At the International Alzheimer’s Research Conference in Chicago, one topic that would have made a good debate might have been: could it be that the major drug companies that are actually doing Alzheimer’s research in India or anywhere else are in competition with the businesses that sell spices to consumers?

For example, could it possibly be that the major drug manufacturers in India will investigate and then come to the conclusion that turmeric couldn’t possibly be that good, that perhaps the element in turmeric, curcurmin isn’t stopping Alzheimers. Because if the drug companies in any country admit openly that curcurmin, an ingredient in turmeric is doing any good to prevent Alzheimer’s then maybe people won’t be grabbing up the drugs.

The drug companies may laugh at the ’hype’ about turmeric. They want to sell commercial drugs to make money. You have to follow the money to get information, or at least their point of view. And then look in the opposite corner and compare the preventive medicine’s research with extracts and foods. Look at the results of investigations of both sides. Are the researchers from the major drug companies investigating turmeric or their own commercial drugs or both at the same time?

Novel turmeric compounds in the news

These are just a few questions to ponder as research continues in various countries. Do you believe the articles based on research in magazines such as Life Extension, or the marketing material from either side? Is the research validated? Double-blind? Who funded the research and why? Read the article, “Novel Turmeric Compound Delivers Much More Curcumin to the Blood,” by Dale Kiefer, Life Extension magazine, October 2007.

Scientific researchers around the world are investigating applications for curcumin that include fighting cancer, arthritis, diabetes, cardiovascular disease, osteoporosis, and reversing the pathological processes underlying Alzheimer’s disease, among other conditions. If turmeric is ’hype,’ why are so many scientists researching its health benefits for so long?

Drug companies will say India or some other country has a lower reported incidence of Alzheimers. But the key word is ’reported.’ Drug manufacturers have to make sure people buy their drugs in India or in any country where there’s a lower ’reported’ rate of Alzheimer’s than in the USA or Europe.

Manufacturers of drugs and their scientists might say that doctors are resisting the decision to make a ’formal’ diagnosis of Alzheimers just because in India it has a strong social stigma. That’s the explanation you might get if you ask the commercial drug researchers….that physicians are willing to report less incidence because of social stigma.

As a Westerner, you don’t know whether physicians in that country or any other nation will under report dementia because it’s a social stigma. You might not know the customs. Who can you believe? Drug companies? Or Western researchers where there’s no social stigma because of the higher rate of Alzheimer’s in the West? Maybe it’s the spice that helps and maybe not. Maybe it’s the meat that causes dementia or maybe not. The theories can drive you to confusion. So you follow your gut that says follow the money.

Western or Eastern medical research: How available are the studies to Americans?

You’ll have to turn to Western scientists specializing in prevention, scientists that don’t work for major drug companies making drugs. What are those researchers studying? Regarding Alzheimer’s, ask whether they are testing curcurmin, extracted from turmeric to find out whether or not it reverses Alzheimers in its early stages or even prevents Alzheimers or other dementia.

You’re going to have to look at the incidence of Alzheimer’s in countries where it’s not a social stigma and where the people are largely vegetarians, even vegans taking supplements and using turmeric or any similar ingredient. On the other end of the investigation are physicians that are looking for evidence that Alzheimer’s is caused by eating meat. Here are some examples in a variety of books. What do you think or theorize? Is there a food cure?

Curcumin is extracted from turmeric. Ask what’s the reason why turmeric and curry powder containing turmeric are both anti-microbial and also a reverser of brain plaque? What does the research actually show now? Or is it all about marketing curcumin? What’s the latest news?

To start your research in order to validate claims of turmeric, begin with the article, Alzheimer’s Disease: Of Emerging Importance. Look at the article’s Alzheimer’s chart. Researchers started with looking at the reported low incidence of Alzheimer’s in India.

The World Health Organization sampled curried vegetarian dishes. Was it the curry, the turmeric, or the fact that not as many people in in India dine on red meat? In the villages, the World Health Organization study found under one percent incidient of Alzheimers in people over age 65. What actually is in the turmeric that is the main ingredient of curry powder? Is it curcurmin alone or the whole food, turmeric, or turmeric mixed with other spices that all work together?

It’s the phytochemical, curcumin. In the USA, curcumin is sold in capsules in health food stores and online and touted in Life Extension Magazine articles. But in India, where doctors report that the Alzheimer’s rate of 4.4 times less than the rate in the burger-chomping USA, people in those Indian villages ate a small amount of turmeric in their curried foods. They didn’t extract the curcumin. However, it’s the curcumin that’s being researched.

Looking at the UCLA Veteran’s Affairs study on curcumin

Your next step would be to go to the UCLA-Veteran’s Affairs study. That research reiterated that curcumin has low toxicity and shows promise in “for the prevention of Alzheimer’s.” Curcumin also is being studied for its anti-cancer potential. Check out the article, Dr Oz: Curcumin Prevents Pancreatic Cancer & More Solutions.

Don’t gulp all that turmeric yet. A teaspoon in a pot of stew is fine. But if you add a tablespoon to your food daily, soon your liver will start pouring out a lot more bile, maybe too much bile and stress for your liver. The whites of your eyes may start to turn yellow.

This would confuse your doctor who may think that maybe you have Wilson’s disease (a copper build-up problem) that turns the whites of eyes yellow. Your dentist will tell you the roof of your mouth, your palate is yellow, and advise you to see a doctor and have your liver tested. So stick with a small amount of turmeric in your diet unless you are supervised medically and your liver bile tested.

Should you take curcumin capsules? That’s up to you and your physician or naturopath based on how the curcumin is affecting your liver bile and any other aspect of your health. Sure, in India, turmeric, a main ingredient of which is curcumin, has been used for six thousand years.

It’s an anti-inflammatory. In India today, turmeric is used as a paste to put on the skin to clear up chicken pox sores and other rashes. Turmeric is anti-microbial. Even hospital floors in India and Sri Lanka often are washed with turmeric and water to sanitize them.

In Ayurvedic medicine of India, turmeric is given to cure inflammation in the body. So your next source of research might be to look at more news of the UCLA-Veteran’s Affairs study. Also see the article at News-Medical Net.

So who’s going to start a clinical trial? And is the clinical trial, if started going to work with healthy volunteers again or target people over age 65 with a variety of issues?

Scientists really need to find out what safe doses of curcumin or turmeric are required. Turmeric is a spice people put in food and not a drug. So can a spice in food turn back or prevent Alzheimer’s and any other dementias? Which ones? Your next stepping stone of validation is to look at the research published in the Dec 7, 2004 online edition of the Journal of Biological Chemistry.

Specifically, curcumin, found in turmeric inhibits the formation of protein fragments better than most drugs being tested at that time as Alzheimer’s treatments. There’s something about the curcumin, its low molecular weight and polar structure. The cucurmin crashes through your blood-brain barrier and binds to the beta amyloids that form the plaque of Alzheimer’s. When the cucurmin binds to the beta amyloids, those amyloids aren’t able to move on and out to worsen Alzheimer’s.

Your next step might be to look at a 2001 study in the Journal of Neuroscience, 2001; 21:8370-8377. Then look at a similar study in Neurobiology of Aging, 2001; 22:993-1005. We know turmeric is an antioxidant and anti-inflammataory. And the inflamed brain of an Alzheimer’s patient results in oxidation.

Want more validation? Look at the UCLA Alzheimer’s Disease Research Center (ADRC) information on their clinical trials of curcumin.

What people want is a safe prevention and treatment of Alzheimer’s and similar-type dementias using a spice or food rather than a drug with more serious side effects that only presently postpones rather than reverses. And in your own reading or research as a consumer, follow the money.

Who’s funding these studies?

The Siegel Life Foundation, Veterans Affairs, Alzheimer’s Association, UCLA Alzheimer’s Disease Research Center and private donors funded the that specific cucurmin research. Next, read the October, 2007 article by Life Extension Foundation’s magazine titled, Novel Turmeric Compound Delivers Much More Curcumin to the Blood.

Other noteworthy resources nutritionists may consider telling consumers about include the books, Dying for a Hamburger: Modern Meat Processing and the Epidemic of Alzheimer’s Disease by MD Murray Waldman and Marjorie Lamb (Hardcover – Jun 30, 2005) or Brain Trust: The Hidden Connection Between Mad Cow and Misdiagnosed Alzheimer’s Disease by Colm A. Kelleher (Hardcover – Oct 19, 2004). Also see: Food for Thought: The Debate over Eating Meat (Contemporary Issues (Prometheus)) by Steve F. Sapontzis (Paperback – May 2004).

Be sure your brand of turmeric, if imported or not doesn’t contain excess lead

Healthcare providers have also seen cases of lead poisoning due to exposure to Indian spices and powders in California. Some turmeric and curcumin supplements have failed a quality review. Last year ConsumerLab.com found 20% of turmeric supplements selected for testing to deliver less than 15% of what the label promised.

The journal Science also reported that feeding mice curcumin, a component of turmeric, alleviates symptoms of cystic fibrosis. Also a study from the American Diabetic Association suggests that turmeric may help to prevent type 2 diabetes.

See, “Integrative Medicine: Curcumin may aid diabetes fight,” a column in the Sacramento Bee’s Integrative medicine section by Drs. Kay Judge and Maxine Barish-Wreden, medical directors of Sutter Downtown Integrative Medicine program in Sacramento. But before you buy turmeric or a cucurmin supplement, here’s how to make sure you don’t buy any of the types of turmeric full of excess lead.

The turmeric associated with all of the California cases was obtained directly from India, Nepal and Bangladesh rather than being sold in local stores. Since they were in unmarked bags it was not possible to identify a manufacturer or a distributor.

You can check out the February 16, 2011 news release, Problems with Some Turmeric and Curcumin Supplements. Also there appeared to be an excess lead problem. See, Turmeric – Curcumin beware of lead contamination – Discussion. And lead was found in numerous imported Indian spices and various powders. See, Caution Advised About Lead in Indian Spices and Powders – NAM.

In the cases of lead poisoning from Indian spices such as turmeric that turned up in California in Alameda, the problem has been with turmeric. The California Department of Public Health has identified cases of lead poisoning associated with lead contaminated spices including chili powder and turmeric, according to the Childhood Lead Poisoning Prevention Branch.

California cases of lead poisoning from turmeric have been found in adults, children and in a pregnant woman

The U.S. Food and Drug Administration (FDA) has set the maximum exposure limit for children at 6 micrograms per day (mcg/day) for children and 75 mcg/day for adults. Indian spices and ceremonial powders have entered the long list of sources where lead has been found. The study in the journal Pediatrics identified Indian spices and cultural powders as a more recent source of lead poisoning. You can read the original study or its abstract, “Pediatric Lead Exposure From Imported Indian Spices and Cultural Powders.”

Four cases of pediatric lead poisoning from Indian spices or cultural powders are described in that study published in the journal Pediatrics. Chronic exposure to spices and cultural powders may cause elevated BLLs. A majority of cultural products contained >1 ??g/g lead, and some sindoor contained extremely high bioaccessible lead levels. Clinicians should routinely screen for exposure to these products.

How does lead get into spices?

The Pediatrics journal study is reported to have been undertaken after several reports of lead poisoning in Indian children in Boston were found. How does lead get into the spices? Actually, the lead can penetrate into spices if they are grown in lead-contaminated soil or can be inadvertently added during the manufacturing or drying process.

Also lead may be intentionally added to add color or weight to the product. Some health care providers also observed that many of these products are brought into the United States when people go back to their home countries or when their families come to visit them here. Many people seeking to save money on the higher cost of organic turmeric at local health food stores and food markets go to the ethnic grocery stores that import spices from India and other countries and buy brands imported from other countries.

Imported Indian spices: Who tests all of them for lead excesses?

For example, the many Indian grocery and ethnic food markets in Sacramento sell a wide variety of turmeric and curry brands and blends. Labels usually are in English. And a huge bag of turmeric is priced low compared to a small bottle of organic turmeric sold in supermarkets or food stores in small spice bottles.

How do you know what brands were tested for lead, even if you pay more money for a tiny spice bottle of organic turmeric or if you buy capsules of cucurmin or turmeric in supplement forms from various vitamin/supplement companies? How do you know who tested and measured the spices for bioavailability, absorption, and lead or other toxic metal content that could have come from the growing soil or added as a filler or a coloring agent?

Consumer Lab tested turmeric and curcumin for lead

The biggest problem with turmeric is that those tested had little curcuminoid compounds in them. And curcumin is supposed to do the most good as far as the anti-inflammatory health benefits are said to happen from consuming a small amount of curcumin, usually found in turmeric.

Supplements containing the herb turmeric or its key compound, curcumin, have become popular in the U.S. ConsumerLab.com cautioned that two out of ten turmeric products recently selected for quality testing were found to provide only 7.7% and 14.7%, respectively, of expected curcuminoid compounds. Unlike some turmeric supplements tested in the past, however, none of the recently tested products exceeded strict limits for lead and cadmium contamination.

Turmeric has been shown to have anti-inflammatory and anti-oxidant activities

Recent research has focused on curcuminoids, the specific compounds in turmeric including curcumin which give turmeric its orange-yellow color. Studies suggest a role for curcuminoids in the treatment of a range of diseases including ulcerative colitis, rheumatoid arthritis, and chronic anterior uveitis (an autoimmune disease of the eye), as well as for indigestion.

According to Nutrition Business Journal, sales of turmeric and curcumin supplements grew to $59 million in 2009, up from $43 million in 2008. But first you have to make sure there’s actually curcumin in the turmeric you’re using.

How do you know whether you’re getting a product with curcumin in the turmeric?

The products that failed Consumer Lab.com’s testing would deliver only a small fraction of the doses expected from their labels. The problem also is with the poor absorption of curcumin. You’d need specially formulated products that can show you how that product will be absorbed. And testing needs to prove the bioavailability.

ConsumerLab.com calculated the cost to obtain a 500 mg dose of curcuminoids, which ranged from 13 cents to 52 cents among products that passed testing, some of which included bioavailability enhancers. For the two products that failed testing, the costs were $3.44 and $7.88, due to the small amounts of curcuminoids that they actually contained.

The ConsumerLab.com report is available at its turmeric-cucurmin supplements review website. Included are findings for ten products selected by ConsumerLab.com as well six that passed ConsumerLab.com’s Voluntary Certification Program.

Products reviewed by Consumer Lab.com include the following: Advance Physician Formulas Curcumin, Doctor’s Best Curcumin C3 Complex with Bioperine, Doctors Purest Ageless Cures Curcumin C3 Complex, Douglas Laboratories Ayur-Curcumin, GNC Herbals Plus Standardized Curcumin, Jarrow Formulas Curcumin 95, Life Extension Super Curcumin with Bioperine, Natural Factors Turmeric and Bromelain, Naturally Enhanced Absorption Curcu-Gel and Curcu-Gel Ultra, Nature’s Life Turmeric Ginger Joint Ease, Nature’s Way Turmeric, Paradise Herbs & Essentials Turmeric, Solgar Turmeric Root Extract, Swanson Superior Herbs Curcumin, and Vitamin Shoppe Standardized Herbs Turmeric Extract.
