There isn’t a vitamin more important to your health than vitamin D. You need it to build and maintain strong bones. Your immune system is crippled without it. Vitamin D deficiency appears to raise the risk of almost every chronic disease, from cancer to diabetes to cardiovascular disease to age-related cognitive decline to auto-immune disease. Yet professor and nutrition researcher Peter Horvath at the University of Buffalo School of Public Health and Health Professions in Buffalo, New York, reports that during Buffalo’s winter months, nearly 50% of the population in Buffalo has insufficient levels of vitamin D, while 25% are outright deficient. “Every cell in your body,” he says, “is responsive to vitamin D. If you’re deficient, you won’t see the health effects for years and it could take months to get your levels back up.” Dr. Horvath is probably using the standard definition of vitamin D deficiency—a blood level of less than30 ng/mL (or 75 nmol/L). However other vitamin D e…

While many factors determine whether or not you will get a coronavirus infection, how bad the infection will be, and how long it will take to recover, there is one all-important factor—the state of your immunity.  Beyond Health’s protocol for building and maintaining a strong immune system includes having your vitamin D blood levels tested with a 25(OH)D test, and getting them up to 40-60 ng/mL (100-150 nmol/L) or more depending on your medical situation. Your immune system requires adequate amounts of vitamin D to function the way it’s supposed to. If you’re low on D, it’s like fighting the coronavirus with one hand tied behind your back. You can raise your vitamin D levels with sun, food and supplements. SUN Sunlight is an inexhaustible source of free vitamin D! The sun’s UVB rays convert cholesterol in the skin into vitamin D. However, since these same UVB rays cause sunburn, light-skinned people need to build up a protective tan gradually. The best approach is…
