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, immune function, and calcium absorption. This high-dose vitamin D3 supplement comes in an amber glass bottle with a safety seal to protect the product integrity. The softgel format is designed for optimal absorption since vitamin D3 is fat-soluble. Due to its high potency, this supplement should only be taken under medical supervision and is typically used to correct vitamin D deficiency rather than for daily maintenance.
