Summer is the time to soak in some rays and get a healthy dose of Vitamin D to store for the winter months ahead.  How do you get Vitamin D safely without risking a sunburn? What if you live in the city? Why is it important? What happens if you don’t get enough? 

How much Vitamin D do I need?

The recommended amount of Vitamin D is a topic of debate in the medical world.

  • The Vitamin D Council recommends adults take in 5,000 IU (international unit).
  • The Institute of Medicine’s Food and Nutrition Board recommends 600 IU a day for ages 1-70
  • The Endocrine Society suggests that 2,000 IU/day is enough.

What if I don’t get enough Vitamin D?

The studies are still out, but here’s what we know:

  • The amount of people with a Vitamin D deficiency is reaching an all-time high.
  • Studies are linking deficiencies to an assortment of health issues and diseases. 

Vitamin D plays an important role in bone growth and development by absorbing calcium and helping regulate the immune system. It is commonly known as “the bone vitamin,” but research shows that Vitamin D acts more like a hormone rather than a vitamin. Almost every tissue type in our body has receptors for Vitamin D and need it for optimal performance.  Receptors are abundant in your heart, pancreas, and brain. Vitamin D deficiency has been linked to heart disease, diabetes, and depression. 

“Vitamin D probably affects every disease.”
Robert P. Heaney, MD, expert from Creighton University

How much Vitamin D Do You Need?

How do you get enough of it if experts don’t agree on the amount needed?  Dr. Heaney studied Vitamin D, osteoporosis and physiology for over 50 years, and the key to his recommended amounts was the measurement. His studies started at 2000 IU per day, and he then measured again 6 months later. If they still tested in the normal range, they would stick to that amount, but if they weren’t, they would double it and continue measuring. Considering genetics, input, and output, recommendations depend on the individual. If you haven’t had a Vitamin D test, most doctors include them in annual physicals. Depending on the amount in your blood they might suggest over-the-counter supplements or start you on a prescribed amount and continue regular measurements. 

How do increase your Vitamin D intake?

Getting outside and exposing your skin to the sunshine for ten minutes each day can help raise your levels of Vitamin D. Be sure to protect against sunburn.

You may find the results to be an easy fix to a variety of health issues you’re experiencing.
