Vitamin K
Vitamin K is an important group of nutrients that mostly impacts bone health. Vitamin K2 is the most similar to that found in your body, and;
- supports cardiovascular system health
- is important for the optimal delivery of calcium, one of the key building blocks for strong, healthy bones
- stems the rate of bone density loss during menopause
- helps to increase bone strength, which may decrease the incidence of falls and fractures in the elderly
Vitamin K is the fastest growing vitamin ingredient in Australia, growing at 30% since last year1.
Vitamin K2 can be found in a variety of foods such as green vegetables (kale, spinach, broccoli, collard greens, etc), meat, dairy products, eggs and fermented foods (yoghurt, cheese, kombucha, etc).
