The Building Blocks to Strong Bones: Calcium, Vitamin D, and Vitamin K

For building and protecting your bones throughout your life, getting the right amount of calcium is essential. But calcium alone won’t get the job done - you also need vitamin D and vitamin K for optimal calcium absorption and bone density. Exercise also plays an important role in keeping your bones healthy and strong.

Calcium: The Bone Builder

Aside from building strong bones, your body needs calcium to handle other important tasks: to move muscles, send messages through the nervous system, help release hormones and enzymes, and circulate blood.

While calcium supports all these critical functions, more than 99% of this precious mineral gets stored in your bones and teeth to keep them healthy and strong – and to have calcium on hand for when you really need it.

Vitamin D: The Calcium Absorber

The deal with vitamin D - before calcium can do its job, it has to be absorbed by your body – and that’s where vitamin D comes in. Vitamin D regulates calcium absorption in the body, maintains calcium and phosphate levels, and promotes bone growth.

Your body produces vitamin D when your bare skin is exposed to sunshine – specifically ultraviolet B rays –making vitamin D known as “The Sunshine Vitamin.” You can also get vitamin D from your diet and supplements like Viactiv Calcium Chews, which delivers 12.5mcg of vitamin D in every tasty chew.

Vitamin K: The Bone Protector

Vitamin K is the key to helping vitamin D as it has been proven to play an important role in bone health. Vitamin K partners with vitamin D to boost calcium absorption, affect calcium balance and increase bone mineral density – helping your body absorb osteocalcin, a protein that studies show may be essential for protecting bones from fractures. Note: if you’re on blood thinning medicines, be sure to talk to your doctor before taking Viactiv Calcium chews.

How Much, and How to Get Vitamin K

It doesn’t take much to get the vitamin K intake you need. For adults and children over 4 years of age, you need just 120mcg a day to meet your recommended daily value – and just one Viactiv Calcium Chew gives you 40 mcg of vitamin K. Leafy greens and vegetables are a great source of vitamin K.
