Vitamin D Supplementation Shown to Reduce Muscle Fatigue
People with vitamin D deficiencies often experience physical fatigue. A recent study suggests that taking vitamin D supplements may increase the presence of phosphocreatine in people with vitamin D deficiencies, and reduce symptoms of fatigue.
Phosphocreatine is a compound that works in conjunction with adenosine triphosphate to produce muscular energy in the human body.
The study included 12 participants with severe vitamin D deficiencies who took a vitamin D supplement and 15 healthy control subjects.
The researchers took MRI scans of the participants at the beginning of the study after they exercised their calves. They then took MRI scans 10-12 weeks after beginning supplementation of vitamin D. The recovery half time for phosphocreatine was reduced from 34.4 seconds to 27.8 seconds as a result of the vitamin D supplementation.
The researchers stated that this is the first study to find a link between vitamin D levels and muscle aerobic function.
The study was conducted by researchers at Newcastle University in the UK. It was published in the March 2013 issue of The Journal of Clinical Endocrinology and Metabolism.
Previous studies have shown vitamin D to be associated with improved kidney health, reductions in the risk of skin cancer, reducing the risk of osteoporosis, combating diabetes, and improving age related eye degeneration.
Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun but it becomes harder for our bodies to process it as we age. A high quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.
