Essential for bone health, muscle contraction, nerve signaling.
Clinical dose: 500-1000 mg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Immune function, testosterone support, protein synthesis, wound healing
Clinical dose: 15-30 mg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Calcium
Marketing claims: "Strong bones," "Prevents osteoporosis." Reality: Calcium works best from food and when combined with vitamin D and weight-bearing exercise. High-dose supplements alone may increase cardiovascular risk. Most Indians get adequate calcium from dairy — supplementation is mainly for those avoiding dairy or with diagnosed deficiency.
Zinc
Marketing claims: "Immune booster," "Testosterone support." Reality: Zinc only boosts immunity or testosterone if you are deficient. Excess zinc (>40mg long-term) can cause copper deficiency and actually suppress immunity. Most multivitamins provide adequate zinc — standalone supplements often provide excessive doses.
