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 help maintain optimal vitamin D levels, support bone health, and promote immune system function. This high-dose vitamin D3 supplement is typically used under medical supervision for individuals with diagnosed vitamin D deficiency or those with increased vitamin D needs. The softgel format helps enhance absorption since vitamin D is fat-soluble. The amber bottle with safety seal helps protect the product from light degradation to maintain potency. As with any high-dose supplement, this should be taken only as directed by a healthcare provider.
