Chromium Polynicotinate vs. Chromium Amino Acid Chelate
Among 4,926 on-market chromium products with an identifiable primary form, 24.6% use Chromium Polynicotinate (1,211 products) and 9% use Chromium Amino Acid Chelate (445).
| Chromium Polynicotinate | Chromium Amino Acid Chelate | |
|---|---|---|
| Quality tier | Tier 2 | Unrated |
| Chromium by weight | — | — |
| Share of market | 24.6% | 9% |
| On-market products | 1,211 | 445 |
| Median declared dose | 120 elemental mcg middle half: 50–200 | 100 elemental mcg middle half: 32.25–120 |
| Most common brands | Douglas Laboratories, Pure Encapsulations, Wonder Laboratories | Trace Minerals Research, The Vitamin Shoppe, Douglas Laboratories |
Doses are declared per serving in elemental mcg. “By weight” is the share of the ingredient that is the nutrient itself (e.g. elemental magnesium in a magnesium salt).
Why Chromium Polynicotinate is tier 2
Picolinate produced higher urinary Cr than two nicotinate supplements and than chloride in the comparative study; its abstract does not rank nicotinate against chloride, and the branded polynicotinate complex was not necessarily one of the products tested.

Why Chromium Amino Acid Chelate is unrated
No dedicated human or animal comparative bioavailability study for this named complex was located.
Source: none found -- insufficient evidence
