Your jaw may hit the floor at how important this nutrient is for mood and immune function and how low the RDA actually is. Here's an article on muscle weakness and vitamin D: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1304730/?page=1 . There are estimates that anywhere from 50-80% of people are vitamin D deficient in the winter. The USRDA is set at 400IU. I've seen studies showing that an adult human can use 4000IU in a day at times. Have your Dr check this also when you go in next time. Cod liver oil is good for this but there is a risk of getting too much vitamin A with cod liver oil.
