There's an epidemic in progress -- and it has nothing to do with the flu. A ground-breaking study found an astonishing 59 percent of study subjects had too little Vitamin D in their blood. Nearly a quarter of the group had serious deficiencies (less than 20 ng/ml).
The study was also the first to show a clear link between Vitamin D levels and the accumulation of fat in muscle tissue -- a factor in muscle strength and overall health. Scientists have known for years that Vitamin D is essential for muscle strength.
Studies in the elderly have showed bedridden patients quickly gain strength when given Vitamin D.
