Klean-D contains 5,000 IU of vitamin vitamin D₃per tablet as targeted support for athletes who train indoors or receive limited exposure to natural sunlight.^‡

Athletes need to train, no matter what: rain or shine, early mornings, late evenings, sore muscles, or low energy. Vitamin D may help to improve the quality, frequency and duration of training, and contribute to faster muscle recovery. Klean-D 5,000 IU contains natural vitamin D₃, providing targeted support for athletes who train indoors or receive limited exposure to natural sunlight. Vitamin D supplementation may also help support athletes' immune health, musculoskeletal strength and physical performance.^‡

INDICATIONS

KLEAN-D may be a useful dietary supplement for athletes desiring healthy vitamin D levels.

FUNCTIONS AND MECHANISM OF ACTION

Vitamin D, also known as the “sunshine vitamin” is an essential vitamin that plays many important roles in the proper functioning of the body. Though classified as a vitamin, vitamin D is actually a key regulatory hormone for multiple physiological processes. It is estimated that 1 billion people, including the elderly, young adults, athletes and children, are vitamin D deficient or insufficient. The main cause of vitamin D deficiency in the athletic population is the direct result of decreased ultraviolet B (UVB) radiation absorption into the skin, which especially affects indoor athletes and those who live and train in northern latitudes.

Adequate vitamin D status is essential for ensuring normal calcium absorption and maintenance of healthy plasma calcium levels.† Besides bone support, vitamin D has many other roles in the body, including modulation of cell growth, neuromuscular and immune function, and inflammatory support. † Clinical research has shown there is a positive association between Vitamin D 25(OH)D serum concentrations, lower extremity function, proximal muscle strength and physical performance. Vitamin D deficiency is associated with diffuse muscle pain, muscle weakness predominantly in the proximal muscle groups, and a reduction in performance speed. A serum 25-hydroxyvitamin D level below 50 nmol/l has been associated with increased body sway and a level below 30 nmol/l with decreased muscle strength. Based on the study by Barker et al, pre-exercise serum 25(OH)D concentrations could influence the recovery of skeletal muscle strength after an acute bout of intense exercise.

Numerous scientists now feel that supplementation with vitamin D at levels greater than previously thought necessary is critical to helping maintain healthy bone remodeling and healthy vitamin D plasma levels.† A committee of the Institute of Medicine reviewed the data on vitamin D needs and concluded that persons are at risk of vitamin D deficiency at serum 25(OH)D concentrations
