Overview
Life Extension's Vitamin D3 softgels deliver 125 mcg, or 5000 IU, per softgel, a dose well above the 400 to 800 IU found in most multivitamins, aimed at people whose levels call for a stronger daily dose.
At one softgel a day the 60-count bottle lasts two months. The formula is gluten free and non-GMO, and D3 is included here for its established roles in bone health and immune function rather than as part of a wider multivitamin blend.
- 125 mcg (5000 IU) vitamin D3 per softgel
- 60 softgels, once daily, two month supply
- Gluten free and non-GMO
- Single-ingredient formula
Who it's for
People advised to take a higher-dose vitamin D3, or who spend little time in sun and want a single-ingredient daily dose rather than a multivitamin's smaller amount. Not intended for anyone who needs a specific low dose, since 5000 IU exceeds typical general allowances.
Strengths and trade-offs
Drawn from this product's published specifications.
- High-potency 125 mcg (5000 IU) dose per softgel
- One softgel per day, easy to track
- Gluten free and non-GMO
- Two month supply per bottle
- Dose is too high for someone who only needs standard maintenance levels
- No other bone-support nutrients like calcium or K2 included
Performance notes
Vitamin D3 (cholecalciferol) is fat-soluble, and delivering it in a softgel with a small amount of oil is a common way to support its absorption compared with a dry tablet.
