What is it Good For?

Healthy bones

Vitamin D is essential for the absorption of calcium and phosphorus, vital minerals for bone health. Adequate vitamin D helps maintain strong and healthy bones, and it's popular with people wanting to prevent osteoporosis and fractures.

Immune defence

Some people take vitamin D supplements to support overall immune function. Vitamin D is involved in the regulation of the immune system, and helps the body defend against infections as well as supporting balanced immune responses.

Mood & mental wellbeing

There is emerging research suggesting a link between vitamin D levels and mood disorders. Some people take vitamin D supplements to support mental well-being, especially during seasons with reduced sunlight exposure.

    Important vitamin for transporting calcium into the bones

    My wife and I have been taking vitamin K2 MK-7 for a couple of years as we understand it helps to transport calcium out of the blood to the bones. A recent bone density scan my wife had in 2024 showed an improvement when compared with her bone scan in 2013. While we cannot confirm why this is, we believe that our whole food, low carbohydrate diet plus the K2 MK-7 vitamins together with vitamin D3 have all played a role in achieving this good result.
