Metagenics Vitamin D3 High Strength delivers 5000 IU of vitamin D3 in a small, easy-to-take daily tablet - ideal for those who need effective, high-dose support. With an estimated one in five people in the UK having low levels of vitamin D, supplementation can play a vital role in supporting immune function, bone health, and overall wellbeing. This convenient, high-strength formula is especially suited to individuals with known deficiency or insufficient levels who need reliable and therapeutic support. Formulated with vitamin D3 - the body's preferred and most easily absorbed form - this supplement provides the same type of vitamin D produced naturally by the skin when exposed to sunlight. This means better uptake and faster utilisation compared to other forms, helping to restore and maintain optimal levels more efficiently. It's a simple and cost-effective way to top up your vitamin D-particularly during the darker months or for those with limited sun exposure. Vitamin D3 contributes to the maintenance of normal bones, teeth, muscle function and immune system activity, and also plays a key role in calcium absorption. It's especially important for older adults, those at risk of falls, and for children during periods of rapid growth. Whether you're looking to support your immune defences, maintain bone strength, or simply safeguard your health year-round, Metagenics Vitamin D3 High Strength is a trusted, high-quality choice.
