28 Mar Vitamin D – Immune Booster Extraordinaire
WIDESPREAD VITAMIN D DEFICIENCY
According to the The National Health and Nutrition Exam Survey (2000–2004) approximately 75% of adults in the US are vitamin D deficient. In support of its worldwide prevalence, a 2018 study examining the data of 35,667 individuals in Turkey found that over 94% had a serum level less than 30 ng/mL (insufficient), 76% had a level less than 20 ng/mL (deficient), and over 32% had a level less than 10 ng/mL (severely deficient). The average serum 25(OH)D level of all individuals in the study was 15 ng/mL, which is indicative of a severe deficiency.
A POWERFUL PROTECTIVE NUTRIENT
Derived from cholesterol – vitamin D is technically a hormone – and is best described as a “super vitamin”, which regulates thousands of genes and metabolic processes in the body. In addition to its powerful anti-microbial and anti-viral activity, vitamin D is needed for the optimal production of the body’s master antioxidant glutathione, which regenerates other antioxidants, is anti-inflammatory, and serves a number of vital protective functions in the body.
A sufficient level of Vitamin D bolsters our immune defenses, and is now believed to be one of our frontline defenses against the seasonal flu and viral infections, and with its powerful anti-inflammatory, immunomodulatory activity aids in preventing life-threatening pneumonia.
In a 2013 study titled, “Influence of vitamin D status on respiratory infection incidence and immune function during 4 months of winter training in endurance sport athletes”, the authors found that individuals with higher blood levels of vitamin D were at lower risk of moderate to severe infections and had greater systemic immunity.
In another study, the same year, titled, Vitamin D Deficiency and Acute Lung Injury, the authors state, “The evidence for the role of vitamin D in lung disease is growing – deficiency has been associated with impaired pulmonary function, increased incidence of viral and bacterial infections and inflammatory disease including asthma and COPD. Studies have also reported a high prevalence of vitamin D deficiency in the critically ill and an association with adverse outcomes.”
ALL THE MORE REASON TO OPTIMIZE YOUR VITAMIN D LEVEL DURING THE PRESENT TIME.
So, what does that mean exactly?
TO DERIVE THE MAXIMUM BENEFIT FROM VITAMIN D – for most people – this means taking 5,000 iu of vitamin D3 per day as a maintenance dose, and to get your vitamin D level tested every 6 months, so that you stay within the optimal window of 50-90 ng/mL. If you’re overweight (or obese), you’re going to need 2-3 times this amount because fat stores sequester vitamin D, which reduces your blood level.
FOR A POWERFUL BOOST TO YOUR IMMUNE SYSTEM, and as a potent anti-inflammatory nutrient (hormone) – you can safely take much higher levels of vitamin D3 in the short-term, for a few days until you’re feeling better. If you feel something coming on, immediately take the following: 1,000 iu of vitamin D3 per pound of body weight, which will give your immune system a powerful boost, and provide you extra support against bacterial and viral infections, as well as speeding your recovery. Make sure to take this higher dose with at least 200 mcg of vitamin K2 (Mk-7), which vitamin D needs to function properly.
TO PUT IT SIMPLY, THE KEY TO STAYING HEALTHY IN THIS DAY AND AGE IS A STRONG IMMUNE SYSTEM
The way to do this involves a combination of eating healthy (e.g. focus on organic fruits, vegetables, grass-fed meats, organic pastured eggs; the highest quality food possible), reducing sugar intake, reducing toxin exposure (e.g. get rid of chemical air fresheners, perfumes, deodorants, harsh cleaning agents, and substitute with natural, safer versions), getting enough rest and good quality sleep at night, moving your body and exercising daily, and keeping your nutrient reserves optimized.
