Overview
Doctor's Best Vitamin D3 softgels deliver 5000 IU (125 mcg) per serving, packed 360 to a bottle, and formulated without gluten, soy, or GMO ingredients.
5000 IU is a higher daily dose than the 400 to 2000 IU range found in many general-purpose vitamin D products, so it suits people whose intake target is already set at that level rather than someone starting from scratch. A 360-count bottle at one softgel a day lines up with roughly a year of use.
- 360 softgels per bottle
- 5000 IU (125 mcg) vitamin D3 per serving
- Unflavored softgel
- Non-GMO, gluten free, soy free
Who it's for
Adults taking a higher-dose vitamin D3 regimen who want a year's supply in one bottle. Not the right fit for anyone who wants a lower IU count or has been told to take less than 5000 IU daily.
Strengths and trade-offs
Drawn from this product's published specifications.
- 5000 IU (125 mcg) vitamin D3 per softgel
- 360-count bottle, close to a year's supply at one a day
- Non-GMO, gluten free, and soy free
- 5000 IU is a high dose not appropriate for everyone without guidance
Performance notes
Vitamin D3 (cholecalciferol) is included here at 125 mcg per softgel, supporting the immune system and, more broadly, bone and heart health markers associated with adequate vitamin D status. The softgel delivery is a fat-soluble vitamin format, and the gluten-free, soy-free, non-GMO label describes the manufacturing rather than the dose itself.
