Vitamin D is one of the most researched vitamins in the human body. Science has found many things that are affected by having too little or too much or even from what source a body’s Vitamin D comes. Vitamin D has been linked to asthma, the immune system, brain function, diabetes, and more.
Yet not every source of Vitamin D is great. Some people find that some supplements, for example, are not as good as others. Scientists also warn that the primary source of Vitamin D, sunlight, can become detrimental when we overdo it, leading to skin cancer.
Over-supplementation of Vitamin D, for example, is linked with general fatigue, appetite loss, headache, and sometimes vomiting, says Food World News. It’s also linked with pregnancy problems, kidney disease, hardened arteries, and a lot of other not-so-great things.
