Sentinel D3 50000 IU is a high-potency vitamin D3 supplement containing 30 softgel capsules. Each softgel provides 50,000 IU of vitamin D3 (cholecalciferol) in an easily absorbable form to support bone health, calcium absorption, immune function and overall wellbeing. This high-dose vitamin D3 supplement is typically used under medical supervision for treating vitamin D deficiency. The softgel format helps enhance absorption since vitamin D is fat-soluble. The amber glass bottle helps protect the product from light degradation to maintain potency. As with any high-potency supplement, this should be taken as directed by a healthcare professional.
