On the membrane of each cell in your body are entry ways called, receptor sites. Each cell has tens of thousands of these sites. They are like a lock and key, much like the children’s toy box of square pieces in square holes, triangles in triangle holes. Each site only allows specific chemicals inside. The password allows the right chemical to enter so it can be utilized by the cell. The cell does not want anything it is not programed for. Because the presence of specific receptor sites exclusive for this vitamin, D is defined as a hormone. Vitamin D is not just for our bones.
Logan Bronwell, author of the article, The Overlooked Importance of Vitamin D Receptors, explains the newest of vitamin D Research by Michael Holick, MD. The data show that nearly every tissue and cell type in the body has receptors for vitamin D! The discovery has changed how we look at our daily needs for this vitamin.
Some of the major points of Vitamin D in Logan Bronwell’s article are:
- Vitamin D deficiency makes one 91% more likely to progress to insulin resistance, or pre-diabetes.
- Low levels of vitamin D increase the risk of non-Alzheimer’s dementia almost 20 times.
- Vitamin D regulates genes that control cell growth and development, immune function, metabolic control, cardiovascular and neurological diseases.
- Although humans can make some of vitamin D in their bodies, most people require addition amounts from diet, sun and supplements to have enough Vitamin D levels.
- From diet of production in skin, Vitamin D is converted to an active form, Vitamin D3, in the kidneys and liver.
- Vitamin D protects brain cells and is powerful against neurodegenerative diseases and can reverse non-Alzheimer’s dementia by nearly 20-fold.
- There is a strong correlation to vitamin D receptors and the regulation of signaling pathways involved in inflammation, tumor growth, and immune system surveillance for cancer- especially in the epithelial cells of the skin, breast, prostate, and colon and other tissues that are prone to cancer development.
- Increase in Vitamin D levels through supplementation has helped in decline of disease activity in rheumatoid arthritis and lupus.
It sounds like a panacea to many ill states. Perhaps it is! Vitamin D is stored in the body. Too much can cause problems, too. What does the article suggest for supplementation levels? ‘Start by taking a high-quality vitamin D3 (I personally believe the best form of Vitamin D from natural food sources) of at least 2,000 IU daily. Small children need at least 400 to 1,000 IU)’. Then get your vitamin D level checked by a qualified practitioner. (25-hydroxyviatmin D for testing)
The article continues to say that if your levels are low, 2,000-8,000 IU daily has shown to increase levels of Vit D. (Make sure you retest for this in your regular check-ups)
