Note: Content may be edited for style and length. Content on this website is for information only. Nutrition 21 is the leading developer and marketer of chromium-based nutritional supplements. The demand for chromium pills -- often sold in the form of chromium picolinate -- is based on a simple and common premise: The mineral supposedly helps build muscle and burn fat. ScienceDaily. This was due to concerns raised by the Expert Group on Vitamins and Minerals that chromium(III) picolinate might be genotoxic (cause cancer). "However the doses were within international guidelines for genotoxicity testing," she says. When Chromium Picolinate is taken as a dietary supplement with Vitamin C supplements, it caused genetic damage to laboratory hamsters. The Alabama scientists believe it does this job by making the insulin receptor work better. But Australian researchers at the University of Sydney and the University of New South Wales found that when chromium picolinate enters cells in the body, it is partially converted into a cancer-causing chemical. ANAHEIM, Calif., March 23 --New evidence has been reported that a popular nutritional and dietary supplement, called chromium picolinate, may be a cancer risk. But one chromium manufacturer says it has conducted extensive human tests. Its main offices are in Washington, D.C., and Columbus, Ohio. American Chemical Society. Until now, though, there was no solid explanation for just how chromium picolinate caused the damage. You may require medications along with healthy consuming and exercise routines to manage your type 2 diabetes. Views expressed here do not necessarily reflect those of ScienceDaily, its staff, its contributors, or its partners. The picolinic form increases Cr absorption from the GI tract, although this remains quite low, around 3%. Chromium is marketed as a protection against Type 2 diabetes and as a so-called "sugar balance" pill to help weight loss. Chromium is believed to help the body process carbohydrates and fats.1 It is marketed as a weight loss aid for dieters and an ergogenic (muscle-building) aid for bodybuilders and athletes. My doctor has not put me on medication for my diabetes at this time. What oral medications deal with type 2 diabetes? Found in vitamins and mineral supplements, Chromium may be necessary for utilization of dietary sugars and carbohydrates by optimizing the effects of insulin. The earliest study that showed the effect of chromium supplementation in decreasing symptoms of diabetes was done in the 1970s, when a patient was given supplemental chromium. ScienceDaily, 24 March 1999. Dec. 11, 2001 -- A popular nutritional supplement, chromium picolinate, has been touted as a fix for weight loss and muscle growth, a potion to help you lose body fat. Possible Link Between Chromium Picolinate and Cancer The results of a study conducted by the University of Alabama in 1999 point to a link between Chromium Picolinate and cancer. (1999, March 24). Chromium picolinate works together with insulin produced by the pancreas to metabolize carbohydrates. As a weight loss supplement chromium picolinate may be effective, yet there are some potential drawbacks including a cancer risk. Now we find out that the body turns chromium-3 into chromium-6. Furthermore, University of Alabama chemists John B. Vincent, Ph.D., and Stephen A. Woski, Ph.D., say their laboratory has found the compound is remarkably stable and unaffected by water, buffers, or blood serum proteins. "If it's stable enough that it gets into the cells intact," says Vincent, "then it could be a big concern.". Chromium picolinate is an organic compound of trivalent chromium and picolinic acid, a naturally occurring derivative of tryptophan. Still, chromium's role in these processes is not well understood. New Treatments That May Change the Game, Understanding Cancer Diagnosis and Treatment. "Popular Diet Supplement May Be A Cancer Risk." Chemists from the University of Alabama in Tuscaloosa, presented findings here today at the national meeting of the American Chemical Society, the world's largest scientific society, which they say show chromium(III) tris(picolinate) causes DNA breakage. ", The doses are indeed "over 50,000 times higher than the level of chromium a human would have in their blood," counters Komorowski. It is called an "essential trace element" because very small amounts of chromium are necessary for human health. www.sciencedaily.com/releases/1999/03/990324062736.htm (accessed December 27, 2020). Supplemental doses of these agents may need to be adjusted, reduced, or omitted in patients with renal dysfunction. Learn about chromium, exposure to which can increase your risk of lung cancer and cancer of the paranasal sinuses and nasal cavity. But Vincent asks, "what happens in six months, or a year, or longer? Chromium is a trace mineral found in two main forms, trivalent chromium (III) and hexavalent chromium (VI). The substance, which has been on the market for 10 years, has also been tested and found safe by the USDA, he tells WebMD. The investigations show that chromium picolinate resulted in very small amounts of weight loss (about 1.1 kg) after the treatment duration. It is not known what actually happens in humans, or even animals when chromium picolinate is consumed. You can take numerous diabetes medications by mouth. We conclude that chromium picolinate did not cause cancer in female rats "They say her studies are 'extremely questionable.'". "There are studies that can be used to determine if a substance is toxic or not, and Nutrition 21 has done those studies, and chromium picolinate has been shown completely safe," he tells WebMD. What oral medicines treat type 2 diabetes? Chromium-6 is recognized as a human carcinogen when it is inhaled. Chromium Picolinate Linked To Cancer. The FDA considers chromium picolinate a nutritional supplement and therefore does not regulate it. P2. Her work further showed that, once inside those laboratory cells, it appeared to induce cleavage of chromosomal DNA. Chromium picolinate, on the other hand, is more readily taken in during digestive processes. Chromium is an essential mineral your body needs in small amounts. ", Stearns found that 58 of 1 million cells had DNA damage, Komorowski points out. Nutrition 21 has conducted "numerous clinical studies involving over 3,000 subjects -- in studies between three months and one year in duration -- and there have been absolutely no side effects," Komorowski tells WebMD. It turns out that chromium side effects also include cancer â itâs very carcinogenic. 3.15.9.4 Chromium Picolinate. Selenium is partially excreted in the urine. A new study found that chromium is partially converted into a carcinogenic form when it enters cells (File photo) The mineral is primarily found in two forms. In her study, Stearns exposed live hamster ovary cells to high dosages chromium picolinate and found a high incidence of mutated cells. The dosage of chromium used in studies ranges from 200 mcg to 1,000 mcg daily, mostly in the form of chromium picolinate. However, the jury is still out on how effective this supplement is when used for these purposes. It is thought that chromium picolinate can help increase muscle mass. A study led by the universities of Sydney and NSW has shown that living cells convert chromium III, a naturally occurring element used as a weight loss and type-2 diabetes treatment, into its âcarcinogenic cousinâ â hexavalent chromium, the industrial pollutant made notorious by the 2000 movie Erin Brockovich and a 2011 chemical spill near Newcastle.
