Best Vitamin D3 Supplements

If you’ve never tried a vitamin D supplement, you should try it. Good for the treatment and prevention of bone disorders, vitamin D is made by the body when the skin is exposed to sunlight. Those who live in especially cold and wintery areas could find themselves lower in vitamin D.

Vitamin D isn’t only important for the promotion of bone growth and absorption of calcium, but for other important functions of the body. Studies done on vitamin D or the “sunshine vitamin” have shown a plethora of benefits. Also obtained through a healthy diet, vitamin D is also known as a pro-hormone involved in many metabolic processes.

Here is a list of key benefits you can obtain from taking a vitamin D supplement: stronger bone health, prevention of bone disease, lessened bone fractures, better physical performance, protection against cancer (breast, colon, prostate, pancreatic, and ovarian), better brain development and cognitive functioning.

Vitamin D supplementation can also reduce depression, reduce risk of Parkinson’s disease, lessen risk of Alzheimer’s disease, protect from multiple sclerosis, improve sleep quality, reduce risk of cardiovascular disease, reduce blood pressure, decrease risk of diabetes (type 1 and type 2), prevent obesity and metabolic syndrome.

Vitamin D also has a large anti-inflammatory role and can be beneficial for inflammatory bowel disease, celiac disease, and cystic fibrosis. Vitamin D is also an effective therapy for dermatitis, asthma, arthritis, and hair loss. Taking a vitamin D supplement can also be beneficial for fertility in men and pregnancy and lactation in women.

These are just some of the many benefits that can be achieved by taking a vitamin D supplement. The rest of this post will cover eight awesome vitamin D3 supplements you can take to ensure your body has enough of this great vitamin!
