Overview
Designs for Health pairs 2000 IU of vitamin D3 with vitamin K in a 120 capsule bottle, aimed at bone and immune support. It is gluten free and vegetarian.
Combining D3 with K reflects the common practice of pairing the two since vitamin K is tied to how the body directs calcium alongside vitamin D. The allergen listing notes dairy, worth checking for anyone avoiding dairy-derived ingredients.
- 2000 IU vitamin D3 plus vitamin K
- 120 capsules per bottle
- Gluten free, vegetarian
- Unflavored capsule form
Who it's for
Suits adults wanting a combined D3 and K capsule at a 2000 IU dose rather than a D3-only formula. Less suited to anyone needing to avoid dairy-derived ingredients or wanting a lower IU dose.
Pros and cons
- 2000 IU vitamin D3 combined with vitamin K
- Gluten free and vegetarian
- 120 capsule count covers an extended supply
- Higher IU dose may not suit everyone's needs
Performance notes
The formula pairs D3 with vitamin K, a combination commonly used because vitamin K plays a role in how the body directs calcium, the typical rationale for stacking the two rather than taking D3 by itself.
