At 5,000 IU (125 mcg) per softgel, this **Vitamin D3** sits at the high-correction end of the dosing range — useful if you're rebuilding levels after a documented deficiency or a low-sun winter, but more than you need for everyday maintenance, which lands closer to 1,000–2,000 IU. It's the cholecalciferol (D3) form, the one your body uses most efficiently to raise and hold blood levels.

This dose backs bone strength, immune function, and dental health, the areas where vitamin D has the strongest clinical evidence. Because D3 is fat-soluble, take the softgel with a meal, as the label suggests, so your body actually absorbs it.

One thing to know: 5,000 IU is above the 4,000 IU everyday upper limit, so treat it as a tool for correcting low levels rather than a forever dose — if you stay on it long-term, get your blood levels checked.
