Vitamin D3 Supplements

SunVit-D3, a vitamin D3 supplement containing pure pharmaceutical grade vitamin D3, was launched in the UK in 2008 by Sunvit-D3 Limited. To maintain healthy vitamin D3 levels, health professionals recommend a daily maintenance of between 400 IU and 2,000 IU of vitamin D3 and we have both 1,000 IU and 2,000 IU in our product range.

Vitamin D benefits are wide and varied and include contribution to the maintenance of normal bones and teeth; contribution to the maintenance of normal muscle function; contribution to the normal function of the immune system and healthy inflammatory response, and contribution to the absorption of calcium and phosphorus and the maintenance of normal blood calcium concentrations.

High Strength Vitamin D3 Tablets

The High Strength range of supplements consist of 3,000 IU/5,000 IU/10,000 IU/20,000 IU/50,000 IU Vitamin D3 in easy to swallow film-coated tablets in convenient blister packs. High strengths should only be taken under medical supervision and advice sought from health practitioner before ordering.

SunVit-D3 products are now the vitamin D3 of choice in many highly respected hospital trusts such as the Central Manchester Foundation Trust, the Imperial College Healthcare NHS Trust in London, the Barnsley Clinical Commissioning Group, Newham, Tower Hamlets and Waltham Forest CCGs.

Sports Performance and Vitamin D

Athletes who train indoors may be at risk of Vitamin D deficiency. It is also important to maintain your Vitamin D intake in the winter months when there are fewer hours of sunlight.

Our 20,000 IU strength has undergone an extensive procedure carried out by the anti-doping laboratory LGC Sport and Specialised analytical service to ensure that it is free from a wide range of substances banned by the World Anti-Doping Agency (WADA). This provides the highest level of assurance for athletes that the product is safe.
