Mineral
Zinc (as Zinc Bisglycinate Chelate)
Also known as: zinc glycinate, zinc bisglycinate, chelated zinc
Zinc is an essential trace mineral critical for immune function, protein synthesis, and DNA replication. Zinc bisglycinate chelate is a highly absorbable form bound to the amino acid glycine.
Primary uses
- immune function
- wound healing
- protein synthesis
- antioxidant defense
- reproductive health
How it works
- component of immune cells and antibodies
- cofactor for over 300 enzymes
- supports collagen formation
- regulates gene expression
Dosage
- Typical range
- 8-11 mg daily (elemental zinc)
- Timing
- can be taken with or without food, though food may reduce absorption
- With food
- absorption better on empty stomach, but food can reduce GI upset
- Duration
- ongoing for maintenance; higher doses for acute immune support should be limited to 2-3 weeks
- Special populations
- pregnant/nursing women: 11-13 mg daily; vegans/vegetarians may need higher intakes
Forms
- zinc bisglycinate chelate· 70/100
Safety
Common side effects
- nausea
- metallic taste
- headache (at high doses)
Contraindications
- do not exceed 40 mg daily long-term without medical supervision
Evidence notes
Zinc has strong RCT evidence for immune support and wound healing. Bisglycinate chelate form shows superior absorption compared to inorganic salts like oxide or sulfate.
Grade A: Multiple well-designed human trials support the main claims.
