Sentinel Vitamin D3 1000 IU is a dietary supplement containing 100 softgel capsules designed to support optimal vitamin D levels. Each softgel provides 1000 IU (25 mcg) of vitamin D3 (cholecalciferol) to help maintain bone health, immune function, and calcium absorption. This supplement is particularly beneficial for individuals who may have limited sun exposure or need to maintain healthy vitamin D levels. The softgel format ensures easy swallowing and optimal absorption since vitamin D3 is fat-soluble. The bottle contains a 100-day supply when taken as directed at one softgel daily. The product comes in an amber glass bottle with a tamper-evident seal to maintain freshness and quality.
