Compare All Forms

Compare different forms of Zinc by bioavailability, conversion rates, and active ingredient content:

Form Tier Steps Elemental Zinc
(mg)
Bioavailability Action
Zinc Bisglycinate Tier 1 0 — Chelated form of Zinc with enhanced absorption due to amino acid binding. View →
Zinc Picolinate

Zinc picolinate, a highly bioavailable form of zinc, support...

Tier 1 0 20.0%

(400mg = 80mg)

Zinc picolinate is a chelated form of zinc, bound to picolinic acid. This chelation enhances bioavailability, allowing for easier absorption and utilization by the body, bypassing initial conversion processes. View →
Zinc Gluconate Tier 3 3 11.0%

(400mg = 44mg)

Basic/low bioavailability form. Cheap raw material with poor absorption or high GI distress. Often poorly utilized by the body, requires 3+ conversion steps. View →
Zinc Oxide Tier 3 3 60.0%

(400mg = 240mg)

Basic/low bioavailability form. Cheap raw material with poor absorption or high GI distress. Often poorly utilized by the body, requires 3+ conversion steps. View →
Zinc Sulfate Tier 3 3 20.0%

(400mg = 80mg)

Basic/low bioavailability form. Cheap raw material with poor absorption or high GI distress. Often poorly utilized by the body, requires 3+ conversion steps. View →

Scientific Evidence

Numerous studies support zinc's role in immune function and wound healing. Research comparing the bioavailability of different zinc forms suggests that zinc picolinate may be better absorbed than some other zinc salts, although more research is needed to definitively confirm this advantage across various populations and dosages. Studies also highlight the potential for zinc supplementation to interfere with copper absorption at high doses and over extended periods.
