This vegetarian-friendly formula supports healthy bones, teeth, and muscles, and is important for normal immune function. Suitable for adults and children over 13 years. It is recommended to take one capsule a day with food. Research suggests that many people in the UK have low or sub-optimal levels of vitamin D, primarily due to insufficient exposure to sunlight, especially during winter months. Vitamin D facilitates calcium absorption for healthy bones and teeth, and contributes to the normal function of muscles and the immune system. One capsule typically provides 2000iu (25µg) of Vitamin D3, which is 1000% of the Nutrient Reference Value (NRV*). Store in a cool, dry place out of reach of children.
