Overview
A gluten-free, non-GMO vitamin D3 softgel at a moderate 1000 IU dose, packaged as a 250-count value size meant to last many months of daily use.
At 1000 IU per softgel this sits at the lower end of common D3 dosing, closer to a maintenance dose than a correction dose for someone testing low. The 250-count size is built for people who already take D3 daily and want to buy less often rather than reconsider their dose.
- 1000 IU (25 mcg) per softgel
- 250 softgels per bottle
- Gluten-free, non-GMO
- Softgel form for fat-soluble absorption
Who it's for
Suits someone with normal vitamin D levels who wants a daily maintenance dose and prefers buying in bulk. Not the pick for someone whose doctor has flagged a deficiency and wants a higher-potency option.
Strengths and trade-offs
Drawn from this product's published specifications.
- Large 250-count supply reduces reorder frequency
- Gluten-free and non-GMO formulation
- Moderate 1000 IU dose suits daily maintenance
- 1000 IU may be too low for a diagnosed deficiency
- No K2 or other cofactor included
Performance notes
Softgel-form D3 is fat-soluble, so absorption is generally better when taken with a meal that has some fat in it rather than on an empty stomach.
