Zinc Bisglycinate Chelate vs. Zinc Amino Acid Chelate
Among 8,549 on-market zinc products with an identifiable primary form, 9.7% use Zinc Bisglycinate Chelate (833 products) and 8.1% use Zinc Amino Acid Chelate (695).
| Zinc Bisglycinate Chelate | Zinc Amino Acid Chelate | |
|---|---|---|
| Quality tier | Unrated | Tier 2 |
| Zinc by weight | 30.6% | — |
| Share of market | 9.7% | 8.1% |
| On-market products | 833 | 695 |
| Median declared dose | 11 elemental mg middle half: 6.85–15 | 12.5 elemental mg middle half: 7–15 |
| Most common brands | XYMOGEN, MegaFood, Bluebonnet | Douglas Laboratories, NATURELO Premium Supplements, NOW |
Doses are declared per serving in elemental mg. “By weight” is the share of the ingredient that is the nutrient itself (e.g. elemental magnesium in a magnesium salt).
Why Zinc Bisglycinate Chelate is unrated
Comparative advantage over gluconate shown in a rat model (~49% vs ~42% absorption with phytate present), not confirmed in a human trial.
Source: PMID 16684142 (animal study, not human) -- uncertain, needs review
Why Zinc Amino Acid Chelate is tier 2
No specific human isotope-absorption study for the generic category (distinct from bisglycinate specifically).
Source: uncertain -- needs review
Tiers summarize published comparative bioavailability or outcome evidence for each form (see methodology).
