Overview
NOW Foods packs 50,000 IU of vitamin D-3 into each softgel, a strength usually reserved for weekly or physician-directed dosing rather than daily use. The unflavored softgels are corn-free, dairy-free, egg-free, soy-free and Halal certified, with 50 in a bottle.
At 50,000 IU per softgel this is a high-potency format built for people with a confirmed deficiency or a doctor-directed dosing schedule, not a general daily multivitamin replacement. Because a single softgel covers many days worth of the standard daily allowance, it is worth checking with a physician before starting.
- 50,000 IU vitamin D3 per softgel

Who it's for
Suits people who have been told by a doctor or blood test that they run low on vitamin D and need a concentrated, infrequent dose. Not the right pick for someone wanting an everyday low-dose D3 softgel to take with breakfast.

Performance notes
Vitamin D3 (cholecalciferol) is the form the body produces from sun exposure and converts efficiently to its active hormone form in the liver and kidneys. At 50,000 IU, one softgel delivers many multiples of the standard daily intake, which is why this strength is typically taken weekly or monthly rather than every day.
