Vitamin D is a fat-soluble vitamin in a family of compounds that includes vitamins D-1, D-2, and D-3. It is produced naturally in your skin in response to sunlight. During winter months, sun exposure dramatically decreases and many people in the Midwest become deficient in the vitamin, without being aware at all.
Thankfully, you can also get vitamin D through food and supplementation – we recommend both!
Vitamin D has several important functions, but the main function is regulating the absorption of calcium and phosphorus to ensure normal growth of bones and teeth. It is also shown to facilitate normal immune function, which becomes especially important during the winter months.
Here are some other benefits to supplementing with Vitamin D.
Vitamin D fights disease.
• reducing your risk of multiple sclerosis, according to a 2006 study published in the Journal of the American Medical Association • decreasing your chance of developing heart disease, according to 2008 findings published in Circulation • helping to reduce your likelihood of developing the flu, according to 2010 research published in the American Journal of Clinical Nutrition
Vitamin D reduces depression. Studies have shown marked improvement in depression episodes for those taking vitamin D. It also appears to help with anxiety, which is extremely helpful during the holidays.
Vitamin D boosts weight loss. In one study, people were able to lose more weight taking a daily calcium and vitamin D supplement than those taking a placebo.
I always joke that if you are unsure if you have a deficiency in vitamin D, you probably already do! You can get blood work done to check your levels, and then supplement accordingly.
