Vitamin D is generally known for its role in maintaining bone and teeth. The importance of this nutrient has been found over time to be more than that, because vitamin D controls the expression of over 200 genes in the body and nearly EVERY tissue in the body has a vitamin D receptor, including the immune system, skin, thyroid, stomach, colon, pancreas, and more. This has shown its importance in almost all systems of the body, including the immune system, nervous and endocrine systems, digestive system, cardiovascular system, integumentary system, and – as we all know – the skeletal system.
Unfortunately, vitamin D – like other Vitamins – cannot be produced and it has to be gotten from other sources, like your diet. However, it is extremely difficult to get enough vitamin D your body needs from food.
Fatty fish (mackerel, salmon, etc.), liver, and eggs contain some, but you have to consume large amounts of them at once for optimal levels of vitamin D. The best source of vitamin D is SUNLIGHT. It is recommended that you consume up to 10,000 UI of vitamin D3 for health benefits. Adequate sunlight is important to achieve these recommended amounts.
Why do people still have low levels of vitamin D?
This is because many people spend an average of over 90% of their time indoors, so they’re not getting nearly the amount of sun needed for proper vitamin D. And when they are outside, they don’t expose enough skin to sunlight to get the amount of sun rays they need.
