Recent research out of Yale University has uncovered an interesting new aspect to the function and benefit of vitamin D in the human body. Preventing colds and influenza.

This fact has led many to speculate as to why with the bulk of theories suggesting the lower temperatures allow the pathogens to survive longer and be transmitted more easily.

Much research is now being done to ascertain the ‘right’ amount for vitamin D supplementation; mostly among the elderly, who are at increased risk of falls and fractures, which are a major cause of death.
