Comparisons / Magnesium vs Vitamin D3
Compare mechanism, clinical dose, safety profile, and products containing each ingredient.
Overview
Magnesium is usually chosen for Most adults (widespread deficiency), while Vitamin D3 is often selected for Most Indians (endemic deficiency).
Supports 300+ enzymatic reactions, sleep quality, and muscle function
Clinical dose: 200-400 mg
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Bone health, immune function, testosterone support - widespread deficiency in India
Clinical dose: 1000-5000 IU
Safety: Possible side effects include mild digestive discomfort, nausea, or headache, typically dose-related and more common when intake is escalated quickly.
Magnesium
Marketing claims: "Natural calm," "Better sleep guaranteed." Reality: Magnesium helps sleep primarily in deficient individuals. If you are not deficient, effects are modest. Magnesium oxide (the cheapest form) has poor absorption (~4%) — glycinate, citrate, and threonate absorb much better (20-30%).
Vitamin D3
Marketing claims: "Sunshine vitamin," "Immune support," "Prevents everything." Reality: Benefits are primarily for deficient individuals (which is most people in India). High-dose claims (50,000 IU) are for medical treatment of deficiency, not daily supplementation. More is not better — toxicity occurs above 10,000 IU/day long-term.
