One of the most notable researchers is Dr. Michael Holick, who wrote the book, The Vitamin D Solution.
Four signs that you are Vitamin D-deficient, according to Dr. Holick, are:
1. You frequently feel fatigue, aches and pains. Osteomalacia, a softening of the bones, is due to Vitamin D and calcium deficiency.
2. You suffer from frequent colds and flu. Vitamin D regulates genes that influence your immune system to attack and destroy bacteria and viruses.
3. You feel depressed. Serotonin, the brain hormone associated with mood elevation, rises with exposure to bright light, and falls with decreased sun exposure.
4. Your head feels sweaty. Excessive sweating in newborns is a common early symptom of Vitamin D deficiency.
Aside from causing such acute symptoms, a lack of sufficient Vitamin D can lead to serious chronic diseases. Optimizing your Vitamin D levels may help prevent cancer, heart disease, autoimmune diseases, infections, mental health conditions, and more.
You are more prone to Vitamin D deficiency if you are over 50, have dark skin or suffer from gut troubles, such as Crohn’s disease, Celiac disease, gluten sensitivity, and inflammatory bowel disease.
Despite its name, Vitamin D is not a regular vitamin. It’s actually a steroid hormone that you get primarily from sun exposure or supplementation.
Some medical experts, such as Dr. Phil Mercola, suggest that getting Vitamin D directly from the sun or a safe tanning bed are best.
If you live in Canada, supplementation with Vitamin D3 most of the year is essential.
Researchers have found that Vitamin D3 (derived from animals) is twice as effective as D2 (derived from plants) in raising levels of Vitamin D in the body, according to Dr. Mercola.
At present, the optimal range of Vitamin D for general health appears to be somewhere between 50 and 70 nanograms per milliliter (which can now easily be determined by a simple blood test). For treatment of chronic diseases, such as cancer, recommendations go even a bit higher than that.
The Endocrine Society’s Clinical Guidelines Subcommittee recommends the following dosages:
*Neonates: 400 to 1,000 IUs
*Children one year of age and above: 600 to 1,000 IUs per day
*Adults: 1,500 to 2,000 IUs per day
However, these guidelines are thought to allow most people to reach a vitamin D level of 30 ng/ml, which many still consider to be sub-optimal for disease prevention.
Also, please note another recommendation from Dr. Mercola: If you’re taking Vitamin D supplements, you also need to take Vitamin K2, which helps move calcium into the areas of your body that need it, such as bones and teeth, and remove it from areas where it shouldn’t be, such as arteries and soft tissue.
It’s amazing how a couple of simple vitamins can be so important to our health and well-being.
