Vitamin D In Sports Performance

Our 1,000 IU and 20,000 IU strength tablets are certified by Informed-Sport and Informed-Choice and have 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).

Informed-Choice and Informed-Sport are quality assurance programs for sports nutrition products, suppliers to the sports nutrition industry, and supplement manufacturing facilities. It is a monitoring program that certifies that a supplement product and/or raw material that bears the Informed-Choice or Informed-Sport logo has been tested for banned substances by LGC’s world-class sports anti-doping laboratory.

This provides the highest level of assurance for athletes that the product is safe to use.  Many sports sectors benefit from our supplements including UK Premier League and championship football teams, Irish Rugby Union and Northern Ireland Sports Institute for winter supplementation of their elite athletes.

In addition, it has been found, through our affiliation with One Dance UK, that athletes who participate in high endurance sports and those who train indoors should also consider supplementing weekly with 1,000 IU and 20,000 IU tablets. You can read the full report findings and abstract carried out as part of the control study here.

Watch our brand new video with Dr. Nicky Keay, Sports and Dance Endocrinologist, as she walks us through why Vitamin D supplementation is important for everyday life and for those who heavily practice dancing, cycling, cardio and strength training.


Professor Matthew Wyon, PhD, CSCS from Research Centre of Sports Exercise and Performance, Institute of Sport at the University of Wolverhampton states:

“Vitamin D supplementation is not only used for treating patients lacking vitamin D but also proven to be vital for elite athletes and dancers for improvements in muscle performance and subsequent reduction injury”.

A recent article in IADMS (International Association for Dance Medicine & Science) describes the role of vitamin D3 in dance medicine and its contribution to the maintenance of normal bones and muscle function.

Case Study – The Royal Ballet

“The Royal Ballet Company has a long association with SunVit-D3 who are our preferred supplier of Vitamin D supplementation for the dancers of The Royal BalletWe undertake autumn and spring blood tests of our dancers to ascertain their Vitamin D levels, then provide SunVit-D3 supplements to take through the winter months. We have seen a significant improvement in Vitamin D levels across the Company over the years and supplementation is now a routine part of the preparation for a dancer to remain fit, strong, and healthy throughout the season.”
