Vitamin D has many beneficial effects, but my comments will be restricted to the effect of vitamin D on cancer.
Interest in this association was started by the observation that certain cancers are less common near the equator, where there is more sunlight exposure, and therefore more natural vitamin D generation in your skin.
The most information on cancer in humans Is available on colorectal, breast, prostate, and pancreatic cancer. Colorectal cancer, highlighted DWW our posting, is the only cancer that apparently is affected by vitamin D.
Several studies have suggested that vitamin D can decrease cancer cell growth, stimulate cell death, and reduce cancer blood vessel formation. Increasing cell death, or apoptosis, is what interests me the most, since this is one of the factors which increases inflammation in aging.
The infographics stated that only 300 international units of vitamin D is necessary to produce a 50 Percent reduction in cancer, and that a healthy diet generally supplies this.
I personally take 5000 international units vitamin D. This produces a blood level of about 60 ng/mL, and what the NFL recommends to keep their players healthy, and well within the maximum recommended level of 120 ng/milliliter.
Excessive vitamin D can produce an elevated calcium blood level, and mine is within normal limits. I take the higher dose because of vitamin D’s other effects, such is benefiting the immune system in a time of Conid-19.
I suggest that you get a vitamin D blood level, and also a calcium blood level if you elect to take more of this useful vitamin.
