Nutri Advanced Vitamin D3 provides 5000iu vitamin D3 per tablet for those who may be deficient in vitamin D or require extra support. **Benefits:** - 5000iu vitamin D3 per tablet, for those who may be deficient in vitamin D or require extra support. - Provided as vitamin D3, the preferred form as it is the same form produced naturally in the skin in response to sunlight, meaning it can be absorbed quickly and easily. - Small tablet size with a one-a-day dosage recommendation - hassle-free way to supplement Vitamin D. - Vitamin D supports many areas of health including the immune system, healthy bones, teeth and muscles - Suitable for vegetarians This formula is suitable for those who may be deficient in vitamin D, or have insufficient levels and require extra vitamin D. Our vitamin D3 is derived from lanolin (sheep wool). It is therefore suitable for vegetarians but not vegans. We recommend regular Vitamin D testing when taking this product. Between October and March, everyone in the UK is at risk of low levels of vitamin D, as we cannot generate enough vitamin D in the skin through sunlight in those months, and it is very difficult to consume enough through food. It is thought that as little as 10% of our vitamin D intake comes from the food we eat. Supplementation with 400iu (10mcg) is recommended to adults and children over the age of one, particularly during the autumn and winter months; and groups at risk of deficiency such as those who have little or no exposure to sun, are recommended to supplement all year round.
