Vitamin K2
- Vitamin K2 is a fat-soluble vitamin found naturally in foods like cheese, cheese curd and natto (a fermented soya bean product). It is also found in smaller amounts in meat and egg yolks.
- Vitamin K2 is involved in the body’s ability to produce, and maintain normal healthy bones, through the formation of osteocalcin - a protein produced in bone matrix. Osteocalcin binds with calcium and results in calcium being deposited into bones and bone mineralisation.
- Some studies have suggested that low vitamin K levels may be associated with reduced bone health.

Calcium
- Calcium is essential for the growth, development and maintenance of normal healthy bones. To form bone tissue in the body, calcium salts form crystals on a matrix of collagen.
- During mineralisation of bone, calcium crystals continue to accumulate and become denser which contributes to bone structure, mass and strength.
- Sufficient calcium intake throughout life is needed to achieve optimal bone mass. Unfortunately, though, less than half of all Australians get their daily recommended intake of calcium.
- Increase your calcium intake from foods such as dairy products, salmon & sardines – with bones, tofu, broccoli and bok choy.

Vitamin D3
- Vitamin D3 is the natural form of vitamin D, produced in the skin after exposure to UV-B rays.
- Vitamin D helps with the absorption of calcium (and phosphorus) during digestion from the intestines and promotes the production of osteocalcin (which we’ve seen plays a role in bone mineralisation).
- Unfortunately, more than 1 in 4 adult Australians may be low in vitamin D.
- To up your vitamin D levels – spend short periods of time in the sun, or include these sources of vitamin D in your diet: fatty fish, beef, butter, eggs, and cod liver oil
