There are many known benefits associated with taking vitamin D, also called the “sunshine” vitamin.  

Wow, who knew?

Did you know that vitamin D was discovered in the early 1920s due to contributions of British biochemist and nutritionist Sir Edward Mellanby in a search to cure rickets?  He proved rickets to be a dietary deficiency disease. In 1922, American biochemist Dr. Elmer McCollum would go on to identify vitamin D by using a rat colony for nutritional research. Other experts would also make valuable scientific contributions in nutritional advancement. Per National Library of Medicine, “Before the twentieth century, it was not possible to describe the essentials of a diet that could support life, growth, and reproduction of higher animals.” Lucky for us, this dietary knowledge is helping humans live longer and healthier lifestyles today.

Good for the body

Vitamin D is good for the human body by promoting calcium absorption in the gut and enabling bone mineralization. Vitamin D regulates many cellular functions of the body – supporting immune health, muscle function, and brain activity. Per Mayo Clinic, numerous studies show that people who get ample vitamin D and calcium in their diets can slow bone mineral loss and help prevent serious bone fractures and age-related osteoporosis (weak and brittle bones).

Note: Vitamin D helps the body absorb calcium. Both are considered essential nutrients for bone health.

Research shows that Vitamin D may contribute to:

• Cognitive health improvement
• Treatments of bone problems and other health issues
• Possible prevention of some cancers

Folks can get vitamin D in three ways:

• Through skin
• From diet
• From supplements

The sunshine vitamin

The body makes vitamin D when direct sunlight converts a chemical in the skin into an active form of vitamin D. People can also get vitamin D from food sources like egg yolks, salmon, sardines and mushrooms. Since vitamin D isn’t naturally found in all foods, or amounts may be lacking in some foods, people can get extra vitamin D from fortified foods like milk and cereal. Vitamin D can also be taken in vitamin form. Supplements are generally a safe way for adults with low vitamin D levels to gain adequate amounts. Supplements may also help those with inadequate exposure to sunlight, insufficient diets, or those who cannot absorb vitamin D to get enough of this all-important vitamin. Not all supplements are made equally, so do consult a health expert for advice. 

How much is right for you?

Vitamin D is a vital nutrient the body needs for building and maintaining healthy bones. It is an essential nutrient that has anti-inflammatory, antioxidant, and neuroprotective properties. Basic recommendations for intake of vitamin D exist. The FDA’s Daily Value recommendations are: 15 micrograms (mcg) for children ages one through three, and 20 micrograms (mcg) per day for adults and for children over four.

Getting it right!

Getting adequate amounts of vitamin D is critical for a strong body, however, individual needs may vary. It’s vital to know how much vitamin D is right for you – and whether you are getting adequate amounts of this key nutrient. While getting too little vitamin D is problematic for the body, taking too much vitamin D can also negate the vitamin’s benefits and present health risk. Again, consult your health care provider to learn what’s right for you.
