Vitamin D3 is considered essential for our bodies as it contributes to the maintenance of normal bones, teeth, muscle function and also supports the normal absorption of calcium and phosphorus. However, it is naturally found in relatively few foods like oily fish, meat and eggs and most of it comes from exposure to sunlight. The UK government recommends that everyone over the age of 1 should be taking 10mcg (400iu) of vitamin D daily, however this is a base level, and the Endocrine Society recommend 1000iu for optimal, therapeutic benefits. Vitamin D toxicity is very rare. In the UK, the upper safe limit is 4000iu per day, however doses up to 10,000iu daily have not been shown to cause toxicity so you can be rest assured that it is not easy to ingest too much vitamin D. We recommend regular testing of your vitamin D levels when taking this product. Most healthy adults should theoretically be able to get enough Vitamin D from being outside in the sunshine, however Vitamin D deficiency is very common throughout the UK. This is as a result of a low level of exposure to sunlight, making Vitamin D synthesis almost impossible during the winter. High strength, natural form tablet

At Nutri Advanced, we use vitamin D3, the body’s preferred form of this nutrient for optimal absorption and efficacy. This is the same form made in the skin in response to sunlight, meaning it is easier and faster for the body to absorb than other forms. Sunlight is the most common source of Vitamin D but due to Britain's climate, it is very difficult to maintain its levels throughout the year. Our D3 High Strength supplement is the same form of D vitamin that is naturally produced in your body when exposed to the sun.

Vitamin D deficiency is quite common, particularly among the elderly. For example, a study conducted at a hospital in Glasgow, Scotland, found an almost universal vitamin D deficiency among a group of 548 elderly patients. Individuals deficient in vitamin D may need 5,000-10,000 IU of vitamin D daily to replenish tissue stores. With these individuals specifically in mind, Thorne´s D-5000 supplies 5,000 IU of pure vitamin D3 in each vegetarian capsule.
