This daily formula combines calcium and magnesium with vitamins D3 and K2, plus boron, in three vegetarian capsules.
Calcium citrate and carbonate provide two sources of calcium, while magnesium citrate and oxide support normal bone structure and mineral metabolism. Vitamin D3 helps your body absorb calcium, and vitamin K2 supports proteins involved in placing calcium where it belongs.
What’s inside
- Calcium citrate and carbonate to support bone strength and density
- Magnesium citrate and oxide to support bone structure and normal muscle and nerve function
- Vitamin D3 to support calcium absorption
- Vitamin K2 as menaquinone-7 to support normal bone mineralization
- Boron to support mineral metabolism and bone health
Why these nutrients work together
Calcium is a major building block of bone, but it doesn’t do the job alone. Magnesium supports the processes that help your body use calcium and vitamin D. Vitamin D3 helps with calcium absorption, while vitamin K2 supports osteocalcin, a protein involved in binding calcium within the bone matrix.
Suggested Use: Adults take three vegetarian capsules daily with meals, or as directed by a healthcare professional.
If you take an iron supplement or iron-containing bariatric multivitamin, separate it from calcium by at least two hours. Consult your healthcare provider before use if you take blood-thinning medication or have been advised to limit vitamin K.
