There are a number of chromium supplements on the market including GTF chromium, chromium polynicotinate, and others. All of the better chromium supplements, including chromium picolinate, are in a trivalent chemical state. Chromium picolinate has the advantage of being hypoallergenic since there is no yeast. Furthermore, most of the chromium research has used the picolinate form of chromium. Chromium picolinate is the best researched and most reliable form available. Each capsule provides 200 mcg of Chromium from chromium picolinate. Caution: Because chromium can increase insulin sensitivity, this may alter insulin requirements in diabetics. There is some evidence that persons with reactive hypoglycemia may also need to use caution with chromium. This applies to all forms of chromium, not just chromium picolinate. For this reason we need to include the following warning-Diabetics/Hypoglycemics: Use only under a physician's supervision. 100 Vcaps per bottle.
