Renal failure may be considered a relative contraindication. The potential for genotoxic effects exists at higher dosages. Daily dosages used in clinical trials for periods of up to 9 months range as follows: brewer's yeast up to 400 mcg/day chromium chloride 50 to 600 mcg/day chromium nicotinate 200 to 800 mcg/day chromium picolinate 60 to 1,000 mcg/day. The currently accepted value for chromium dietary intake is 25 mcg/day for women and 35 mcg/day for men. The role of supplemental chromium remains controversial. Clinical Overview UseĬhromium supplementation has been studied for a variety of indications, especially diabetes and weight loss, but clinical studies have shown inconsistent results. So before you buy a bottle of chromium, ask yourself whether you’re seeking fat loss or muscle gain.Common Name(s): Chromium chloride, Chromium nicotinate, Chromium picolinate
Chromium nicotinate plus#
Using chromium nicotinate plus exercise, however, may increase the weight loss that normally occurs with regular exercise. Nonetheless, it would seem that chromium picolinate given to healthy, obese women supports fat loss. The study authors didn’t suggest a mechanism for this effect. This is the first study to show that chromium nicotinate plus exercise can cause a significant decrease in body fat. The doses used here were twice the amount used in previous studies on women. Still, it would be quite noteworthy if it was muscle. A 2.9% increase in weight over nine weeks may not seem like much. It’s rather intriguing that chromium picolinate may cause weight gain without exercise. Exercise by itself or with picolinate didn’t significantly affect body weight, fat mass, or fat-free-mass levels. It also caused a lower insulin response to an oral glucose load. Supplementing with chromium picolinate resulted in statistically significant weight gain (+2.9%), caused by a gain in fat-free mass with a slight gain in fat mass.Įxercise plus chromium nicotinate caused a significant reduction in body fat (-1.6%). It involved step aerobics, cycling for 30 minutes, and resistance training. The subjects were divided into four groups: 1) chromium picolinate, 2) chromium picolinate with exercise, 3) chromium nicotinate with exercise and 4) exercise plus placebo. They received (200 mcg twice a day) for nine weeks. In a recent investigation conducted at the University of Texas at Austin, a group of healthy, sedentary, obese women was given either chromium picolinate or chromium nicotinate. In addition, other evidence suggests a positive effect on body composition. Some research (not all) has shown a favorable effect of chromium on risk factors related to cardiovascular disease. Chromium Picolinate & Nicotinate Research Absorption is always a key selling point among different versions of the same ingredient. Chromium nicotinate is chromium bound to niacin. What Is Chromium Picolinate & Chromium Nicotinate?Ĭhromium picolinate is a somewhat newer form of chromium that absorbs better than other forms. The other two, in case you’re curious, are testosterone and growth hormone. Insulin is one of the anabolic hormones in the body.
What Is Chromium?Ĭhromium is a mineral that’s vital for normal insulin function. Remember, just because it may not work for you doesn’t mean it won’t work for anyone. Then again, this mineral does appear to be of benefit in certain populations. Some say that many of the claims surrounding chromium are plain hype.
Few supplements (except for creatine) have received as much popular press. A study performed several years ago at Bemidji State University in Minnesota showed purported ergogenic benefits of chromium in well-trained athletes. Better still, one that also spares lean muscle. No news sounds better to a bodybuilder than hearing about a supplement that can burn body fat. Chromium Picolinate and chromium nicotinate.
