Does everyone have a sunny warm tropical vacation planned for this winter? If you don't and even if you do you will probably only be there for around a week; with that said how are you obtaining your Vitamin D this winter? There are several foods that contain Vitamin D and even some foods that are fortified with Vitamin D, such as cereals and milk.
However, about 80%-90% of Vitamin D is obtained by sunlight. With the cooler weather most people are usually completely covered up or just not outside near as much as they would be during the warmer months minimizing their exposure to the sun. It is tough this time of year to expose your skin to the sun because of the cooler temperatures but if you get a chance on a rare warm winter day make sure to get out to not only enjoy the beautiful day but to minimize your chance for Vitamin D deficiency.
Studies of Vitamin D have shown that it helps prevent osteoporosis, boosts the immune system, and helps those with blood pressure issues. Many studies also emphasize how deficiency in Vitamin D can lead to autoimmune diseases and certain cancers. If you are wanting to prevent yourself from being deficient you should add 600-800 IU of Vitamin D into your supplementation regimen.
In addition Vitamin D is shown to help improve bone strength. If you don't have Vitamin D at your house next time make sure to pick some up at the store and you'll be set!
