If you are feeling extra soreness and aches during the winter season this could be due to the lack of Vitamin D in your diet. Vitamin D is known as a sunshine vitamin since our bodies make vitamin D from the sun’s ultraviolet rays. Due to the winter weather we are in short supply of this vitamin. Vitamin D is crucial for calcium absorption and bone health. A study showed that patients that were suffering with back pain had inadequate levels of vitamin D. They were all given vitamin D supplements for 3 months and symptoms improved 95%. Vitamin D supplements are good for you, easy to take, usually have no side effects and can typically cost as little as 7 to 10 cents per day.
