The basics

Vitamin D3 (cholecalciferol) and Vitamin K2 (menaquinone) are both fat-soluble vitamins, each serving essential roles in the body.

However, factors like limited sunlight exposure, skin type, age, and geographical location can limit this process, making dietary intake or supplementation necessary. Vitamin D3 supports several bodily processes, including calcium absorption for bone growth and maintenance, normal immune function, brain health, mood regulation, and energy levels. Optimal levels of Vitamin D3 are above 100 nmol/L.

On the other hand, Vitamin K2 is less well-known but equally crucial for health. It mainly exists in two forms, MK-4 and MK-7, with MK-7 having a longer half-life and thus more bioavailable. This vitamin plays a key role in activating proteins responsible for incorporating calcium into the bones (osteocalcin) and inhibiting calcium deposition in artery walls (Matrix Gla Protein), supporting bone and cardiovascular health.

The Science

Vitamin D3, known as the "sunshine vitamin, " is essential in many physiological functions, such as calcium absorption in the gut, bone growth and maintenance, immune regulation, and mood enhancement. It's critical to ensure calcium and phosphate adequate serum concentrations for normal bone mineralisation.

Vitamin K2 (as menaquinone-7 or MK-7) activates proteins involved in calcium metabolism, such as osteocalcin, which incorporates calcium into bones, and Matrix Gla Protein (MGP), which inhibits arterial calcification. Thus, it not only assists Vitamin D3 in promoting bone health but also ensures that the absorbed calcium is effectively used in the body and does not contribute to arterial calcification.

Optimal magnesium and B12 levels are necessary to maximise the benefits of Vitamin D, while Vitamin K2's co-administration is crucial to prevent potential side effects related to unregulated calcium metabolism.

How will I know its working?

You may experience stronger bones, improved mood and energy levels, and enhanced immune function.
Since effects can be subtle and long-term, regular lab tests can verify improved blood vitamin D and calcium levels.

When to take it?

Take 1 tablet daily with food and water, unless specified otherwise on the sachet.
