Vitamin D Deficiency
Insufficient vitamin D may cause girls to have weak muscles.
Vitamin D deficiency is known to weaken the muscular and skeletal systems. A new study has found that vitamin D is connected to muscle power in adolescent girls.
The researchers measured vitamin D in 99 girls between the ages of 12 and 14. They found that 75 percent of the participants had vitamin D levels lower than optimal.
New research also suggests that vitamin D deficiency may also increase the risk of cancer, heart disease and autoimmune disorders.
Scientists and medical professionals believe that vitamin D deficiency is rampant, particularly among dark skinned people living far from the equator. Recent studies suggest that up to 55 percent of apparently healthy adolescents may be vitamin D deficient.
