Reference figure: elemental zinc

Zinc compared

Every variant is normalised to elemental zinc per serving — zinc picolinate and zinc gluconate carry different amounts of zinc per milligram of compound.

Documented batch measurements first, then linked lab reports and sourced declarations. Reports exceeding stated limits rank last. Equal evidence is ordered by active-ingredient price. This ranks documentation, not health effects.

The range in this list is wide — per gram of active ingredient, the most expensive entry costs about 3× the cheapest. That is not a fault in the table: depending on the compound, a capsule holds many times less active ingredient than the same amount of powder. This column is what makes that difference visible.
