There are many vitamins and minerals that our bodies need. No nutrient is necessarily better then the other. However, it is important to know the different vitamins and understand why we need them. Today we will be looking at Vitamin D.
Vitamin D also known as the Sunshine Vitamin is becoming a rather popular vitamin lately and with good reason too! Did you know that anywhere from 50-85% of people are deficient in vitamin D? Why are we all so defiant in this vitamin? What is so great about vitamin D? What can happen if we are deficient? With so many people needing vitamin D, I though it was high time this blog looked into the why’s and how’s of this vitamin.
What is Vitamin D?
Vitamin D is actually not a vitamin at all but rather a fat soluble hormone. There are two main types of Vitamin D: Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D3 is the preferred form as it is the one that your body actually makes and is the one that is most easily absorbed. Vitamin D2 is not easily absorbed however; it is the most common form to be added to milk and other fortified foods, as it is cheaper. The only reason for someone to prefer D2 to D3 is because D2 is vegan whereas D3 is an animal product (usually wool).
Why do we need Vitamin D?
Vitamin D is generally noted for it’s benefit in bone health and in keeping us from becoming sick due to it increasing our immunity. What you may not know is that Vitamin D is important for many other reasons.
Vitamin D deficiency can result in:
Sensitivity to low-level radiation
Increases diabetes risk
How do we get Vitamin D?
The sun is the best source of vitamin D and is how the body natural synthesizes vitamin D. It is actually possible to make about 10,000 IU of vitamin D from the sun in only 20 minutes, if you are fair skinned and out in full sun. However, it is hard to get enough vitamin D from the sun now. There are a few things that make the sun a hard source of vitamin D; 1) living in northern climates where direct sunlight is hard to come by for parts of the year 2) having darker skin – melanin makes it harder to synthesis vitamin D 3) age, as the older you get the harder it is to make vitamin D 4) sunscreen
– wearing sunscreen completely blocks your body’s ability to make vitamin D.
You can also get Vitamin D from food sources. One of the most popular food sources is cod liver oil. While it is certainty not the most tasty form to get vitamin D from, it does give you quite a bit and it also gives you vitamin A which helps absorption. Other food sources are fish, milk and eggs.
Many people however, decide to make things certain and get their vitamin D from a supplement. Naturally the sun and food sources are the preferred method of vitamin D but when it isn’t the easiest way then supplementing is perfectly all right. However, you should choose a supplement that includes oil because vitamin D is fat-soluble. This means that dry vitamin D tablets are not the best option. It is also important to choose a vitamin D3 supplement, as D3 is the form that is recognized by your body and better absorbed. We like to use Carlson’s Vitamin D3 Drops.
How much Vitamin D should you take?
The Institute of Medicine (IOM) revised it’s recommendations for vitamin D in 2010 and now suggests 400 IU for infants 0-12 months, 600 IU for people 1 – 69 years, and 800 IU for those over 70.
Many doctors however feel that this amount is still much too low and many recommend 1000-2000 IU per day with 4,000-6,000 IU for pregnant or nursing mothers.
