Chromium Chloride vs. Chromium Amino Acid Chelate
Among 4,926 on-market chromium products with an identifiable primary form, 14.2% use Chromium Chloride (700 products) and 9% use Chromium Amino Acid Chelate (445).
| Chromium Chloride | Chromium Amino Acid Chelate | |
|---|---|---|
| Quality tier | Tier 3 | Unrated |
| Chromium by weight | 19.5% | — |
| Share of market | 14.2% | 9% |
| On-market products | 700 | 445 |
| Median declared dose | 100 elemental mcg middle half: 35–120 | 100 elemental mcg middle half: 32.25–120 |
| Most common brands | New Chapter, GNC Mega Men, Nature Made | 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 Chloride is tier 3
Produced significantly lower 24h urinary Cr than picolinate in the same crossover study -- cheapest/most common multivitamin form but weakest absorption signal.

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
Tiers summarize published comparative bioavailability or outcome evidence for each form (see methodology).
