You're getting 2,000 IU of **Vitamin D3** per serving as cholecalciferol — the preferred form your body uses most efficiently. That dose sits right in the middle of the 1,000–5,000 IU clinical range, enough to maintain healthy blood levels for most people and support bone density, immune function, and mood regulation.

Since D3 is fat-soluble, your body absorbs it better with a meal containing some fat. The gummy format already includes sugar and tapioca syrup, but no added fat source — so pairing it with food matters here. There's no **Vitamin K2** in the formula, which is often paired with D3 to help direct calcium toward your bones rather than soft tissue.

If you're correcting a deficiency or live in a northern climate with limited sun exposure, 2,000 IU may not be enough — many practitioners recommend 4,000–5,000 IU daily in those cases. You'd need to double your serving to reach that range, which cuts the 45-serving bottle to about three weeks.
