Magnesium
Strong EvidenceMineral Supplement
Magnesium is an essential mineral that supports muscle function, sleep quality, and stress management. Most adults benefit from 200-400mg daily, with magnesium glycinate being the best-absorbed form for general use.
Zinc
Strong EvidenceEssential Trace Mineral
Zinc is a critical mineral for immune defense, skin health, and testosterone production. A landmark Cochrane review found zinc lozenges reduced cold duration by 33% when started within 24 hours of symptom onset. The recommended dose is 15-30mg daily for general health.
Calcium
Strong EvidenceEssential Macromineral
Calcium is essential for bone strength and muscle function. Adults need 1,000-1,200mg daily from food and supplements combined. Calcium citrate is better absorbed than carbonate, especially on an empty stomach. Always pair with vitamin D and K2 for optimal bone benefit.
Iron
Strong EvidenceEssential Trace Mineral
Iron is essential for oxygen transport and energy production. Only supplement if deficient — excess iron is harmful. Ferrous bisglycinate is the best-tolerated form with high absorption. Typical therapeutic dose is 18-65mg elemental iron daily for deficiency.
