**Vitamin D3** at 2,000 IU per softgel — solidly within the clinically studied range of 1,000–5,000 IU/day for supporting bone density, immune function, and mood. The form is cholecalciferol, which your body can use directly without conversion, and the olive oil base in each softgel provides the fat needed to absorb this fat-soluble vitamin effectively.

At 2,000 IU, you're comfortably above the conservative RDA of 600 IU and well below the 4,000 IU upper limit, making this a safe daily dose for long-term use without the need for regular blood monitoring. The 180-count bottle gives you a full six months at one softgel per day.

If you're actively correcting a deficiency or you get very little sun exposure, 2,000 IU may not be enough — many practitioners recommend 4,000–5,000 IU in those situations. For general maintenance in someone with moderate sun exposure, this dose is a reasonable starting point.
