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 in the body. This high-dose vitamin D3 supplement comes in an amber glass bottle to protect the contents from light degradation. The softgel format helps enhance 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 treat diagnosed vitamin D deficiency. The 30-count bottle allows for convenient monthly dosing when prescribed by a healthcare provider.
