Vitamin D3 is important for good overall health and strong and healthy bones. It’s also an important factor in making sure your muscles, heart, lungs and brain work well and that your body can fight infection.
Your body can make its own vitamin D3 from sunlight. You can also get vitamin D3 from supplements and a very small amount comes from a few foods you eat.
The vitamin D3 that you get in your skin from sunlight, and the vitamin D3 from supplements, has to be changed by your body a number of times before it can be used. Once it’s ready, your body uses it to manage the amount of calcium in your blood, bones and gut and to help cells all over your body to communicate properly.
Vitamin D isn’t like most other vitamins. Your body can make its own vitamin D when you expose your skin to sunlight. But your body can’t make other vitamins.
Also what makes vitamin D unique compared to other vitamins, is that when your body gets its vitamin D, it turns vitamin D into a hormone. This hormone is sometimes called “activated vitamin D” or “calcitriol”.
If your body doesn’t get enough vitamin D to keep it healthy, this is called vitamin D deficiency. Severe vitamin D deficiency can sometimes cause a condition called rickets in children and a condition called osteomalacia in adults. Both of these conditions cause soft, thin, and brittle bones.
A lack of vitamin D has also been linked to some other conditions such as cancer, asthma, type-II diabetes, high blood pressure, depression, Alzheimer’s and autoimmune diseases like multiple sclerosis, Crohn’s and type-I diabetes.
Your body gets most of the vitamins and minerals it needs from the foods that you eat. However, there are only a few foods that naturally contain any vitamin D. Most foods that contain vitamin D only have small amounts, so it’s almost impossible to get what your body needs just from food.
Because there are only small amounts of vitamin D in food there are only two sure ways to get enough vitamin D
1.Exposing your bare skin to sunlight to get ultraviolet B (UVB).
You don’t need to tan or to burn your skin in order to get the vitamin D you need. Exposing your skin for a short time will make all the vitamin D your body can produce in one day. In fact, your body can produce 10,000 to 25,000 IU of vitamin D in just a little under the time it takes for your skin to turn pink. You make the most vitamin D when you expose a large area of your skin, such as your back, rather than a small area such as your face or arms.
2. Taking vitamin D supplements.
The Vitamin D Council recommends taking vitamin D3 rather than vitamin D2. Vitamin D3 is the type of vitamin D your body produces in response to sun exposure, while vitamin D2 is not.
proto-col vitamin D is type 3 and at 5000IU is the dose recommended by the Vitamin D Council for an adult. proto-col vitamin D is formulated by Professor Greg Whyte OBE PhD BSc FBASES FACSM. As the summer comes to an end we should all turn to vitamin D supplements to maintain optimal health.
