Why is Vitamin D Critical for Health?
Vitamin D is a steroid hormone. It is synthesized by UVB (Ultra Violet Light) from the sun. LDL Cholesterol is converted to Vitamin D in the skin by yes, you read that correctly, UVB sunlight. Sun block and clothes block this production which is another reason why I believe sun block is a terrible idea, however that’s a discussion for another day. I would highly suggest getting your levels measured, as well as getting hs-CRP measured. Highly Sensitive CRP is the gauge of inflammation in your body whereas Vit D is the water that puts out the fire (inflammation). Vitamin D levels should be 80-120 in my opinion to be optimal. Anything less notes that you need work. hs-CRP should be as close to 0 as you can get. One of vitamin D’s most important actions is to modulate the immune system, as receptors for vitamin D are found on T Killer Cells. These are the same cells that HIV wipes out in its victims. Even vitamin D deficiency turns off the epigenetic’s which is that protect us from viruses bacteria and fungal infections.
Here are a list of diseases associated with vitamin D levels at 30 or below:
- Seizures and muscle tonight us along with heart failure and newly born children
- Cancer of all types
- High blood pressure
- Osteoarthritis and rheumatoid arthritis
- Mental illness of all types
- Radiation poisoning
- Chronic pain
- Multiple sclerosis and most auto immune diseases
- Muscular weakness
- Diabetes, especially metabolic syndrome and type two diabetes
So what does vitamin D really do?
- Vitamin D facilitates increased intestinal absorption of phosphorus and calcium as well as suppression of parathyroid hormone secretion to increase our plasma calcium concentrations. It does not, however, dictate where this calcium deposit in our bodies.
- Vitamin D levels above 50 are associated with increased Adiponectin levels. High adiponectin means you are less likely to be obese. It also means your leptin levels are low. So higher vitamin D levels can help us trim our fat stores. Decreasing Fat can help us avoid insulin resistance and the eventual development of type two diabetes.
- It is a natural antibiotic that helps white blood cells clear infections. It helps us defend ourselves from viruses and bacterial infections. In the gut lining, it activates T regulator cells to protect the intestinal lining and the GALT that lives behind the breast borders. Vitamin D also blocks the intracellular inflammatory signals of NF Kappa beta and TNF alpha, both of which play a role in many pathologic diseases, such as cancer, autoimmunity, and obesity.
- Vitamin D inhibits the hormone renin in our kidneys, which helps prevent high blood pressure. It also protects the kidneys from high levels of uric acid production that come from the end stage of fructose metabolism.
- Usually, the skin makes 10,000 to 20,000 IU’s of vitamin D. Excess vitamin D3 is then broken down to its degradation products. These degradation products have been shown to inhibit psoriasis by preventing the skin from reproducing at a faster rate than normal, the pathology found in psoriasis. Anyone with psoriasis should check their vitamin D levels.
- In autoimmune diseases, we need to advocate for much higher levels of vitamin D. Why? Low Vitamin D is associated with leaky gut syndrome which increases systemic inflammatory processes.
- Higher vitamin D levels are associated with longer telomere lengths. This means that Optimal vitamin D levels reduce cellular aging, reduce the use of our stem cells, and decrease the leakiness of our mitochondria. If your vitamin D level is low your telomeres will be shortened, putting your health at risk, as well as, faster aging and Neolithic disease.
Vitamin D does have many other functions in the body. Vitamin D is one of the most critical markers used for determination of your overall healthiness. If vitamin D levels are below 60 I would strongly suggest getting more sun exposure and eating foods that are high in vitamin D. Most wild-caught fish and seafood are high in vitamin D. Getting your vitamin D levels to an optimal level is not only critical for health but can increase your wellness and mental attitude.
