Chromium Picolinate vs. Chromium Nicotinate Glycinate Chelate
Among 4,926 on-market chromium products with an identifiable primary form, 38.8% use Chromium Picolinate (1,909 products) and 13.4% use Chromium Nicotinate Glycinate Chelate (661).
| Chromium Picolinate | Chromium Nicotinate Glycinate Chelate | |
|---|---|---|
| Quality tier | Tier 1 | Unrated |
| Chromium by weight | 12.4% | — |
| Share of market | 38.8% | 13.4% |
| On-market products | 1,909 | 661 |
| Median declared dose | 100 elemental mcg middle half: 37.2–200 | 100 elemental mcg middle half: 40–200 |
| Most common brands | Emergen-C, Vitamin World, vitafusion | XYMOGEN, Bluebonnet, Ultima |
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 Picolinate is tier 1
Produced significantly higher 24h urinary Cr than chloride/nicotinate forms in a randomized crossover; the form used in the positive Anderson 1997 glycemic-control RCT.
