came across this good article while looking this up

Many Forms of Chromium
There are many forms of chromium; the following is the most common:
Chromium picolinate (bound to picolinic acid)Chromium chloride (bound to chloride; lowest absorption rate)Chromium aspartate (bound to Aspartic Acid)Chromium amino acid chelate (bound to vegetable amino acids)Chromium nicotinate; polynicotinate (bound to niacin)Chromium GTF (one molecule of Chromium, two molecules of Nicotinic Acid and one molecule each of Glutamic Acid)
First, let’s talk a bit about what picolinate is.
Picolinate is one of many different types of “carriers” that in essence “carry” a mineral so it can be absorbed. These carriers are known as chelators. Picolinic acid, produced from the amino acid tryptophan in the liver and kidneys and transported to the pancreas, is the body’s prime natural chelator. It has been shown to be the most efficient chelator for other trace minerals such as:zinc, manganese, iron, molybdenum, and copper.
Based on science, it is known that mineral uptake by tissues is far greater when the mineral is carried by a picolinate. And based on this knowledge, as well as the presence of picolinic acid in our own body, the idea that this form of any mineral being dangerous is simply absurd.
Dr. Richard Anderson, one of the most respected researchers regarding chromium, has subjected rats to several thousand times the dosage of chromium picolinate without a toxic effect. Of course, chromium picolinate has been taken by millions of people for years and it is notably very safe and non-toxic.
