Even though it is readily available and crucial for our body to fight disease, almost half of the American population is deficient in vitamin D.
This deficiency is also known as the hidden cause of numerous chronic preventable diseases, such as heart disease, diabetes, depression, muscle pain, osteoporosis, many cancers, fibromyalgia, osteoporosis, osteopenia (bone loss) and even autoimmune diseases.
“A growing body of evidence shows that vitamin D plays a crucial role in disease prevention and maintaining optimal health. There are about 30,000 genes in your body, and vitamin D affects nearly 3,000 of them, as well as vitamin D receptors located throughout your body.”
Namely, vitamin D acts as a hormone and gene modulator, limiting cancerous cell growth and boosting cell differentiation. Therefore, it effectively inhibits cancer growth, especially breast, colon, prostate, and ovarian cancer.
Also, it prevents infections, common colds, and the flu, and scientists have found that people who are lower in it are more prone to weight gain.
The primary source of vitamin D for our body is the exposure to sunlight. Exposure to sunlight that makes our skin slightly red triggers the production of 10,000 to 25,000 international units (IU) of Vitamin D in our bodies.
Autoimmune diseases like lupus, type 1 diabetes, multiple sclerosis, inflammatory bowel disease, and rheumatoid arthritis are very rare in people from certain parts of the world who have blood levels of vitamin D between 42 and 65 ng/mL (105 and 163 nmol/L).
