In the UK, sunlight isn’t strong enough for most people to make enough vitamin D from October to March, which is why UK guidance recommends a daily supplement through autumn and winter.

Vitamin D also contributes to the maintenance of normal teeth and the normal absorption and utilisation of calcium. For a bone-focused routine, pair it with High Strength Vitamin K2, the natural partner to vitamin D3, or save on both with our Bone Health Bundle.

Take 1 capsule a day with a meal. Each bottle holds 100 capsules, over three months’ supply, at around 21p a day.

The Science, Simply Put

Vitamin D3 provides 4,000 IU (100µg) of vitamin D3 per serving as natural cholecalciferol, the same form of vitamin D produced in the skin following exposure to sunlight.

The formula also includes calcium from coral calcium, which naturally contributes a range of trace minerals alongside the calcium itself.

Vitamin D contributes to the maintenance of normal bones and teeth, normal muscle function, the normal function of the immune system, and the normal absorption and utilisation of calcium. This is especially important during the darker months of the year when sunlight levels in the UK are lower.

It is a simple daily formula designed to complement a balanced lifestyle.
