👍 Good value — below the typical Vitamin D3 cost-per-dose.
🔬 Studied dose — the commonly-studied Vitamin D3 dose is 2,000 IU/day. You'd take ~2.5 servings/day to reach it — about $0.11/day at this price.Maintenance dosing is commonly 1,000–2,000 IU/day; higher only on a clinician’s advice after a blood test.
