This **Vitamin D3** softgel delivers 2,500 IU (62.5mcg) per dose — a comfortable maintenance-to-correction amount that sits well above the 600 IU RDA and well under the 4,000 IU daily upper limit. If you're shoring up winter or limited-sun levels, that's enough to meaningfully raise and hold your blood levels, supporting bone strength and immune function.

It uses cholecalciferol (D3), the form your body raises and holds vitamin D levels with most effectively, and because D3 is fat-soluble, the olive-oil softgel plus the label's with-a-meal instruction both aid absorption.

At 2,500 IU, this sits in the middle ground — more than a basic everyday dose, less than a high-dose correction protocol. If bloodwork shows you're well below range you may want more; for steady year-round coverage, it's right in the pocket.
