Absorption Enhancers

Taking with a protein-containing meal enhances zinc and amino acid absorption; vitamin B6 facilitates cystine metabolism

Absorption Inhibitors

High-dose calcium supplements reduce zinc absorption; phytates in whole grains inhibit zinc uptake; coffee and tea reduce zinc bioavailability

Side Effects

Possible Side Effects

Generally well-tolerated at recommended doses; high zinc intake may cause nausea, vomiting, and metallic taste; excess vitamin B6 over prolonged periods may cause peripheral neuropathy

Toxicity Risk

Low

Interactions

Medication Interactions

Zinc may decrease the absorption of quinolone and tetracycline antibiotics; take at least 2 hours before or 4-6 hours after the antibiotic. Vitamin B6 may reduce the effectiveness of Levodopa (for Parkinson's disease) when taken alone.

Supplement Interactions

Zinc competes with copper for absorption - prolonged high-dose zinc may cause copper deficiency; iron supplements reduce zinc absorption - take separately

Special Populations
