The Power of Vitamin D

Vitamin D has been shown to extensively effect bone and immune results.  A meta analysis was performed by PB Tomlinson and his colleagues from the College of London, whereby research on Vitamin D and muscle power in 310 healthy adults ages 18 to 40 years, was evaluated.  The various trials performed lasted from four weeks to six months and included Vitamin D dosages ranging from 4000IU per day to 60,000IU per week.  The mean standardized difference in both up and lower muscle strength was 0.32, which led the researchers to conclude that vitamin D indeed played a significant role in increasing muscle strength.
