At 2,000 IU (50 mcg) per softgel, this is a straightforward everyday maintenance dose of **Vitamin D3** — above the 600 IU RDA and within the 1,000–5,000 IU clinical range, so one daily softgel covers your bone, immune, and dental bases without overthinking it. It uses cholecalciferol, the D3 form that raises and holds your blood levels more reliably than D2.

Since vitamin D is fat-soluble, take it with a meal — the softgel's soybean oil base already aids absorption. If you get limited sun, live through dark winters, or are correcting a known deficiency, you may need 4,000–5,000 IU daily, so it's worth checking your blood levels rather than assuming this covers you. For routine year-round maintenance, 2,000 IU is a sensible baseline that stays well under the 4,000 IU upper limit.
