Mineral
Zinc (as Zinc Bisglycinate)
Also known as: Zinc glycinate, Chelated zinc, Zinc bisglycinate chelate
Zinc is an essential mineral involved in immune function, protein synthesis, and wound healing. Bisglycinate chelation enhances bioavailability and reduces gastrointestinal irritation compared to zinc oxide or sulfate forms.
Primary uses
- Immune function
- Wound healing
- Protein synthesis
- Testosterone support
- Antioxidant defense
How it works
- Component of 300+ enzymes
- Cofactor for immune cell development and function
- DNA synthesis and cell division
- Antioxidant protection
Dosage
- Typical range
- 8-11 mg elemental zinc daily
- Timing
- Consistent daily dosing recommended
- With food
- Take with food to reduce nausea and enhance absorption
- Duration
- Ongoing supplementation for optimal immune and general health support
- Special populations
- RDA: 11 mg (adult males), 8 mg (adult females), 11-12 mg (pregnant/lactating), 2-11 mg (children). Upper limit: 40 mg/day to avoid copper antagonism.
Forms
- Zinc bisglycinate (chelated form)· 70/100
Safety
Common side effects
- Metallic taste
- Nausea (reduced with chelated form and food)
- Copper deficiency with excessive long-term use
Contraindications
- Hemochromatosis (consult healthcare provider)
Evidence notes
Extensive RCT evidence supports zinc's role in immune function, wound healing, and overall health. Bisglycinate chelation shows superior absorption and tolerability in clinical comparisons.
Grade A: Multiple well-designed human trials support the main claims.
