Chromium Picolinate
From the Nature's Way label -
Chromium Picolinate is an essential part of the GTF (Glucose Tolerance Factor) molecule. GTF is a cofactor for insulin in the
regulation of blood sugar, which is necessary for proper metabolism.
From the Now label -
Chromium is an essential trace mineral that works with insulin to support healthy blood glucose levels and plays an important role in
the proper utilization of protein, fat and carbohydrates.

The following are excerpts from U.S. National Institutes of Health -
Overview
Chromium is known to enhance the action of insulin, a hormone critical to the metabolism and storage of carbohydrate, fat, and
protein in the body. In 1957, a compound in brewers' yeast was found to prevent an age-related decline in the ability of rats to
maintain normal levels of sugar (glucose) in their blood. Chromium was identified as the active ingredient in this so-called
"glucose tolerance factor" in 1959.
There are reports of significant age-related decreases in the chromium concentrations of hair, sweat and blood, which might
suggest that older people are more vulnerable to chromium depletion than younger adults. One cannot be sure, however, as chromium
status is difficult to determine. That's because blood, urine, and hair levels do not necessarily reflect body stores.
Furthermore, no chromium-specific enzyme or other biochemical marker has been found to reliably assess a person's chromium status.
Chromium is sold as a single-ingredient supplement as well as in combination formulas, particularly those marketed for weight loss and
performance enhancement. Supplement doses typically range from 50 to 200 mcg. Please consult with a doctor or other trained
healthcare professional before taking any dietary supplements.
Personal Intake
Dietary intakes of chromium cannot be reliably determined because the content of the mineral in foods is substantially affected by
agricultural and manufacturing processes.
In 1989, the National Academy of Sciences established an "estimated safe and adequate daily dietary intake" range for chromium. For
adults and adolescents that range was 50 to 200 mcg. In 2001, DRIs [Dietary Reference Intakes] for chromium were established.
The research base was insufficient to establish RDAs [Recommended Dietary Allowances], so AIs [Adequate Intakes] were
developed based on average intakes of chromium from food as found in several studies.
Adult women in the United States consume about 23 to 29 mcg of chromium per day from food, which meets their AIs unless they're
pregnant or lactating. In contrast, adult men average 39 to 54 mcg per day, which exceeds their AIs.
The average amount of chromium in the breast milk of healthy, well-nourished mothers is 0.24 mcg per quart, so infants exclusively
fed breast milk obtain about 0.2 mcg (based on an estimated consumption of 0.82 quarts per day). Infant formula provides about
0.5 mcg of chromium per quart. No studies have compared how well infants absorb and utilize chromium from human milk and formula.
Possible Benefits
Dieting
Chromium supplements are sometimes claimed to reduce body fat and increase lean (muscle) mass. In several studies, chromium's
effects on body weight and composition may be called into question because the researchers failed to adequately control for the
participants' food intakes. Furthermore, most studies included only a small number of subjects and were of short duration.
Lipid metabolism
Chromium deficiency impairs the body's ability to use glucose to meet its energy needs and raises insulin requirements. It has
therefore been suggested that chromium supplements might help to control type 2 diabetes or the glucose and insulin responses in
persons at high risk of developing the disease ... Overall, the value of chromium supplements for diabetics is inconclusive and
controversial.
Type 2 diabetes and glucose intolerance
There is considerable interest in the possibility that supplemental chromium may help to treat impaired glucose tolerance and type 2
diabetes, but the research to date is inconclusive. No large, randomized, controlled clinical trials testing this hypothesis have been
reported in the United States. Nevertheless, this is an active area of research.
The effects of chromium supplementation on blood lipid levels in humans are also inconclusive. In some studies, 150 to 1,000
mcg/day has decreased total and low-density-lipoprotein (LDL or "bad") cholesterol and triglyceride levels and increased
concentrations of apolipoprotein A (a component of high-density-lipoprotein cholesterol known as HDL or "good" cholesterol) in
subjects with atherosclerosis or elevated cholesterol or among those taking a beta-blocker drug.
Cautions
Few serious adverse effects have been linked to high intakes of chromium, so the Institute of Medicine has not established a Tolerable
Upper Intake Level (UL) for this mineral ...
Certain medications may interact with chromium, especially when taken on a regular basis. Before taking dietary
supplements, check with your doctor or other qualified healthcare provider, especially if you take prescription or over-the-counter
medications. [See their report for details.]
