Sentinel Vitamin D3 50,000 IU is a high-potency dietary supplement containing 30 softgel capsules. Each softgel provides 50,000 IU of vitamin D3 (cholecalciferol) to support bone health, calcium absorption, immune function, and muscle strength. This high-dose vitamin D3 supplement comes in an amber glass bottle to protect from light degradation and maintain potency. The softgel format helps optimize absorption since vitamin D3 is fat-soluble. This product is typically used under medical supervision for those with diagnosed vitamin D deficiency or increased needs. The bottle features a tamper-evident seal for safety and product integrity.
