LifeSource Vitamins Zinc Gluconate 50mg provides the most extensively researched and cost-effective form of zinc supplementation with proven immune support and cold-fighting benefits.* This premium zinc gluconate formula delivers excellent bioavailability and gentle tolerability, making it the ideal choice for daily immune maintenance and therapeutic zinc supplementation.* As one of the most widely studied zinc forms, zinc gluconate offers reliable, research-backed results for immune function, wound healing, and overall cellular health.* Zinc gluconate is formed when zinc is bound to gluconic acid, creating a highly stable, water-soluble compound that your body readily recognizes and absorbs.* Produced in FDA-registered, GMP-certified facilities and 3rd-party lab tested for purity, potency, and label accuracy. Contains 50mg per tablet—consult healthcare provider for appropriate dosing.*

In addition, we reference reviews from 39 leading health organizations and insights from 20 top global universities to ensure our guidance aligns with credible science.*

Clinically Studied Benefits (with research)

• Shortens common cold duration — When started within 24h of symptoms, zinc lozenges/tablets (incl. gluconate) may reduce cold length. (NIH/PMC — Hemilä, 2016)

• Immune cell function — Zinc is required for neutrophil, NK cell, and T lymphocyte activity; supplementation restores immune defense. (NIH/PMC — Prasad, 2008)

• Wound healing — Zinc aids tissue repair; supplementation improves epithelial healing outcomes. (NIH/PubMed — Momen-Heravi, 2017)

• Eye health — Antioxidant + zinc (AREDS/AREDS2) slowed progression to advanced AMD in at-risk adults. (NIH/PubMed — AREDS Report 8, 2001; NIH/PubMed — AREDS2, 2013)

Additional Studies Showing Promising Benefits*

• Skin health (acne) — Some RCTs found zinc gluconate reduced lesion counts; evidence is mixed. (NIH/PubMed — Dréno, 2001)

• Metabolic markers* — Small trials report improvements in glycemic control and inflammation. (NIH/PubMed — Khorsandi, 2019)

University / Academic Context*

• Zinc gluconate — absorption — Widely used in trials due to stability and water solubility; consistently shown effective in immune studies. (NIH/PubMed — Devarshi, 2024 review)

Global Evidence & Authoritative Reviews*

• NCCIH — Notes zinc may shorten colds if started promptly; avoid intranasal zinc. (NCCIH — Zinc)

• NIH ODS — Provides dietary reference intakes & UL = 40 mg/day adults. (NIH/ODS — Zinc)
