Vitamin D3 (Unflavoured)

The Science in Sport Vitamin D3 is formulated with 5000iu vitamin D3.

Vitamin D3 is one of the most popular daily supplements and it is associated with a number of health and performance benefits: increased cognition, immune health, bone health, muscle repair, recovery and muscle function.

Benefits of Science in Sport Vitamin D3

Vitamin D3 deficiency is common in both the general public and athletic populations. This may be due, in part, to: living at far northern or southern latitudes, training indoors, protective clothing, sun-screen or consciously avoiding sun exposure. All of these factors reduce the specific sun exposure required for the body to synthesize vitamin D3.

Studies reporting positive effects of vitamin D3 supplementation often measure performance and health benefits from correcting deficiencies. More specifically, vitamin D3 supplementation has been shown to support immune function. Additionally, during exercise stress is placed on the working muscle, resulting in muscle tissue breakdown. The adaptive process of repairing the muscle promotes muscle remodelling and drives performance improvements. Supplementing with vitamin D3 may have a beneficial role in skeletal muscle repair and remodelling.

Vitamin D3 is tested under the Informed Sport Certification program. This approach involves testing every single batch of SIS finished product, which leaves the Company’s factory, screened against the 2018 World Anti-Doping Agency (WADA) list. Banned substances including steroids are tested to the level of 10 Nanograms per gram, and stimulants to 100 Nanograms per gram. Batches (sampled at the beginning, during and end of each product batch) receive the recognised and respected Informed Sport* certificate and Science in Sport provides the documentation to athletes on request.
