    PRODUCT INFO

    Vitamin D3 supports the foundations your body relies on every day. It contributes to calcium absorption for strong bones and teeth, supports muscle function, and supports a healthy immune system.

    Your body makes Vitamin D3 from sunlight, but in the UK that’s often in short supply – especially with long hours indoors or during darker months.

    Each capsule delivers 50µg (2000IU) in the same form your body produces naturally – a reliable way to keep bones strong, muscles working, and your immune system ready year-round.

    UNDER THE SURFACE

    Shorter days, long hours indoors, and heavy training all reduce the amount of Vitamin D your body can make from sunlight.

    In the body, Vitamin D isn’t just stored – it’s converted in the liver and kidneys into its active form, calcitriol, which acts like a hormone to switch on key processes. It helps your gut absorb calcium and phosphorus for strong bones and teeth. It supports healthy muscle contraction through calcium control. And it primes immune cells so they respond when you need them.

    With steady D3 intake, you close that gap. In the short term, that means your bones absorb the minerals they need, your muscles work more effectively, and your immune system stays responsive.

    Over time, those benefits build into stronger bones, sustained muscle function, and immune defences that stay active year-round. That’s the foundation of lasting capability: keeping your fundamentals solid so you can train harder, recover better, and stay resilient.
