Overview
This NOW Foods formula pairs calcium and magnesium at a 2:1 ratio in tablet form, a combination often used in bone-support routines. The 250-tablet bottle is kosher, vegan and vegetarian, and free of dairy, egg and soy, making it a straightforward pick for people avoiding those allergens.
The 2:1 calcium-to-magnesium ratio is the detail that sets this apart from single-mineral calcium tablets, since magnesium plays a role in how the body uses calcium. NOW does not list a flavor beyond unflavored, and there is no mention of vitamin D3, so anyone relying on this alone for absorption support may want to check whether their diet or other supplements cover that.
- 2:1 calcium to magnesium ratio
- 250 tablets per bottle
- Dairy, egg and soy free
- Kosher, vegan and vegetarian certified
Who it's for
Suits shoppers wanting a two-mineral bone formula from a mid-size supplement brand rather than separate calcium and magnesium bottles. Not the choice for anyone needing vitamin D3 included or a liquid or gummy format.
Strengths and trade-offs
Drawn from this product's published specifications.
- 2:1 calcium-magnesium ratio in one tablet
- Kosher, vegan and vegetarian
- Free of dairy, egg and soy
- 250-count bottle for extended daily use
- No vitamin D3 included in the listed attributes
- Tablet form only, no capsule or powder option
Performance notes
The formula's value rests on the 2:1 calcium-to-magnesium ratio, a proportion some bone-health protocols favor over calcium alone. As tablets, absorption depends on taking them with food and adequate water, standard practice for mineral supplements of this type.
