Vitamin D3 2,000 IU
If you work indoors, you are probably low. Most people are.
Vitamin D comes primarily from sun exposure, and modern life happens indoors. An estimated 40% of American adults are deficient, with higher rates in winter and in northern states.

Vitamin D3 (cholecalciferol), the same form your skin produces in sunlight and the form used in most clinical research. Each serving delivers 2,000 IU, a daily maintenance dose for keeping levels in the healthy range.
Vitamin D status is linked to bone health, immune function, and mood regulation across a large body of research. Supplementation reliably raises blood levels, and correcting deficiency is one of the most well-supported interventions in nutrition. The nuance: megadoses have not shown added benefit in most trials. Consistent, moderate intake is what the evidence supports.
Best for: Indoor workers, anyone in a northern climate, and most adults through the winter months. If you have never tested your vitamin D level, assume you are closer to deficient than optimal.
Not for: People with conditions affecting calcium metabolism should consult their doctor. If bloodwork shows your levels are already optimal year-round, you may not need it.
One serving daily with a meal that contains fat, since D3 is fat-soluble and absorbs better with food. Morning or evening makes no meaningful difference. A blood test once a year tells you whether the dose is right for you.
