Vitamin D has been making headlines lately as a recent study revealed that at least 9% of young Americans are vitamin D deficient! 1 Experts were surprised by those numbers, and now more is being done to help everyone understand the importance of vitamin D when it comes to good health. We encourage you to take a moment and learn little more about this important nutrient.
What is vitamin D?
Vtamin D is also known as a pro-hormone due to the fact that it helps to regulate development and metabolism (especially in the bones), while contributing to hormone production. 2 Therefore, it is important to consume the correct amount of vitamin D; too much is just as bad as too little. 2 3 Although getting too much vitamin D usually requires heavy supplementation, and there are now blood tests available to help you monitor your vitamin D levels.
So how does vitamin D contribute to your good health? Let’s take a look at some of it’s important functions once inside of the body:
- Healthy bone development – Vitamin D helps to maintain proper levels of calcium in the blood and boosts calcium deposits the bones. 2 3
- Cancer prevention – Since vitamin D is important to normal cellular growth and function, it may also play a role in the prevention and treatment of certain cancers. 2 3
- Healthy immune system – Vitamin D regulates the immune system as well as inflammation, making it very helpful for arthritus and autoimmune disorders, including inflammatory bowel disesase. 3
Sources of vitamin D
The two sources of vitamin D are exposure to sunlight and diet. When UV-B (ultra-violet B) rays in sunlight combine with cholesterol in skin cells, cholecalciferol (vitamin D3) is produced. However, UV-B rays are only present with great intensity between 10 AM and 2 PM in the warmer and tropical latitudes. 2
A more reliable source of vitamin D is your diet. Vitamin D in the diet can come from both plant and animal sources. However, it appears that the animal form (cholecalciferol or vitamin D3) has a better chance of being metabolized correctly within the body. 3 When you take vitamin D3, it is coverted by the liver and kidneys into a fully active form called calcitriol; so that it may perform the many functions listed above. 2 3
How much vitamin D do we need?
The USRDA of vitamin D is 400 IU. 3 However, some people may find that they need more vitamin D to help achieve and/or maintain optimum health. If you plan on taking more than 1000 IU of vitamin D daily, it may be a good idea to get your blood levels tested periodically in order to avoid toxicity. Also, high stress seems to increase the need for vitamin D and calcium within the body. 2
Vitamin D therapy
So what is the best way to get more vitamin D? We feel that a variety of methods in moderation may work the best. If you can, spend some time in the sun without sunscreen; 20-30 minutes, 2-3 times per week, during the peak hours of the day is optimal. You do not need to get burned or even tan.
You may also decide to take vitamin D supplements along with calcium and magnesium (to prevent a calcium deficiency). We like to use our Liquid Vitamin D along with our Liquid Calcium/Magnesium in some juice. For the results, take our Legendary Minerals with vitamin D and cal/mag to enhance absorption and assimilation. Use these products daily for the best results.
We feel that Vitamin D is a very important nutrient when it comes to good health; one that might have been forgotten over the course of the past few decades. However, we are glad that vitamin D is getting the mainstream attention it deserves so that everyone can enjoy better health. We wish you the very best in health.
