Summer is the time of year to soak in some rays and get a healthy dose of Vitamin D to store for the winter months ahead.
But you’re probably wondering how do we get Vitamin D safely, without risking a sunburn?
What if we live in the city?
And on top of that, why is it important and what’s the big deal if we don’t get enough?
The recommended amount of Vitamin D is a topic of debate in the medical world. While the Vitamin D council recommends adults take in 5,000 IU (international unit), the Institute of Medicine’s Food and Nutrition Board recommend 600 IU a day for ages 1-70 and then the Endocrine Society advises 2,000 IU/day is enough.
The studies are still out, but here’s what we do know, the amount of people with a Vitamin D deficiency is reaching an all-time high and 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 and is more commonly known as the bone vitamin, but research has found Vitamin D acts as a hormone rather than a vitamin.
The studies have found almost every tissue type in our body has receptors for Vitamin D and requires it for optimal performance. Among these tissues, receptors are abundant in your heart, pancreas and brain; hence, Vitamin D deficiency has been linked to problems including heart disease, diabetes and depression.
The late expert from Creighton University, Robert P. Heaney, MD has gone as far to say, “Vitamin D probably affects every disease.”
So we know why it’s important, but how do we get enough of it if experts can’t even 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 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, in, ut 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 in severe cases, start you on a prescribed amount and continue regular measurements.
Here’s how you can help with your intake.
Getting outside and exposing your skin for ten minutes each day can raise your levels of Vitamin D. But if you’re fair-skinned, live in the city, or don’t get outside much, that’s ten minutes too many. Outside of supplements, the best way is through your diet.
