Overview
Pure Encapsulations Vitamin D3 delivers 125 mcg, or 5,000 IU, of vitamin D3 per capsule in a 120-capsule bottle, framed around bone, joint, heart, colon and immune health, in a hypoallergenic, gluten-free and non-GMO formula.
5,000 IU is a higher daily dose than the standard 1,000 to 2,000 IU found in many vitamin D products, typically used by people with a doctor-identified low vitamin D level rather than as a general daily multivitamin substitute. Pure Encapsulations positions the brand around hypoallergenic manufacturing, keeping the capsule free of common allergens and additives found in some other vitamin D lines. At 120 capsules, the bottle runs about four months at one capsule daily.
- 125 mcg (5,000 IU) vitamin D3 per capsule
- 120 capsules per bottle
- Hypoallergenic, gluten-free, non-GMO

Who it's for
Suited to adults who have been advised to take a higher-dose vitamin D3, and to anyone sensitive to fillers or additives who wants a hypoallergenic formula. Not a fit for someone who only needs a standard 1,000 to 2,000 IU maintenance dose.
Strengths and trade-offs
Drawn from this product's published specifications.
- High-dose 5,000 IU vitamin D3 per capsule
- Hypoallergenic, gluten-free, non-GMO formula
- Framed around bone, joint, heart and immune support
- High dose calls for medical guidance before starting
- 120-capsule bottle needs restocking around every four months
Performance notes
Vitamin D3 supports calcium regulation, which is why this formula lists bone and joint health alongside immune and heart function. The 125 mcg (5,000 IU) dose is well above typical maintenance levels, generally reserved for correcting a confirmed low level rather than everyday supplementation. Pure Encapsulations builds the capsule around hypoallergenic manufacturing standards, meaning fewer added binders and fillers than some competing brands.
