Manganese Gluconate vs. Manganese Citrate
Among 4,675 on-market manganese products with an identifiable primary form, 24.9% use Manganese Gluconate (1,162 products) and 19.2% use Manganese Citrate (898).
| Manganese Gluconate | Manganese Citrate | |
|---|---|---|
| Quality tier | Tier 2 | Tier 2 |
| Manganese by weight | 12.3% | 30.3% |
| Share of market | 24.9% | 19.2% |
| On-market products | 1,162 | 898 |
| Median declared dose | 2,000 elemental mcg middle half: 1,000–3,000 | 2,000 elemental mcg middle half: 1,000–2,700 |
| Most common brands | Emergen-C, DC, Wonder Laboratories | Ultima, Metagenics, Pure Encapsulations |
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 Manganese Gluconate is tier 2
Same caveat -- no human comparative bioavailability data located; acceptable by convention only.
