When we think of "vitamins," we know they're super-important for health.
But vitamin D is special.
It's difficult to get enough vitamin D; vitamin D is, therefore, a very common deficiency.
So, let talk about how much of this critical fat-soluble vitamin we need, and how you can get enough. The three ways to vitamin D are exposure to the sun, consuming vitamin D containing food, and through supplements.
Why is vitamin D important, and how much do we need?
Vitamin D helps us absorb calcium from our food and acts like a hormone to help us build strong bones, Vitamin D can also help with immune function, cellular growth, and help to prevent mood imbalances such as depression and seasonal affective disorder.
Not getting enough vitamin D can lead to bone diseases like osteomalacia. Inadequate vitamin D can also increase your risk of heart disease, autoimmune diseases, certain cancers, and even death. The "official" minimum amount of vitamin D to strive for each day is merely 400-600 IU. Many experts think that this is not nearly enough for optimal health.
To ensure you get adequate amounts of vitamin D, you can implement any combination of the three vitamin D sources mentioned above on a weekly basis.
How can I get enough vitamin D from the sun?
Your skin makes vitamin D when it's exposed to the sun; that's why it's referred to as the "sunshine vitamin." How much vitamin D your skin makes depends on many things. Location, seasons, clouds, clothing, all affect the amount of vitamin d you skin can produce from the sun. One standard recommendation is to get about 5-30 minutes of sun exposure between 10:00 am - 3:00 pm to the face, arms, legs, or back. This should be done without sunscreen, at least twice a week. Of course, we should always avoid sunburns and of course in some locations (and seasons of the year) it's not easy to get sun exposure. So, how can we get enough vitamin D in other ways?
