Nature's Bounty Vitamin D3 2000 IU is a dietary supplement containing 150 softgel capsules. Each softgel provides 2000 IU of vitamin D3 (cholecalciferol) to support bone health, calcium absorption, immune function, and overall wellness. This supplement comes in an easy-to-swallow softgel form for optimal absorption, as vitamin D3 is fat-soluble. The dark bottle helps protect the product from light degradation to maintain potency. Vitamin D3 supplementation can be particularly beneficial for those with limited sun exposure or increased vitamin D needs. As with any supplement, consult with a healthcare provider before use.
