With so much media coverage on the bad of being out in the sun, it is no surprise that we are now seeing major health problems from the lack of sunshine. The body makes vitamin D from sunlight. We also get it from some fish oils, and we can take it as a nutritional supplement.
Rickets in children is not a thing of the past.
The active form of vitamin D is cholecalciferol, or D3. It comes from the sun as UVB rays. It is also found in cod liver oil, lambs wool, and animals produce it on their fur and feathers. Glass blocks most of the UVB out.
The active form in the blood is calcitriol. The storage form is calcidiol (note spelling difference from calcitriol) and is the one measured in the blood. Calcitriol has powerful anti-cancer properties. Edward L. Giovannucii, MD, said, “I would challenge anyone to find an area or nutrient or any factor that has such consistent anti-cancer benefits as vitamin D.” Vitamin D helps in many conditions, including osteoarthritis, Parkinson’s disease, Type 1 diabetes, and heart disease. It is important in immune function.
Ergocalciferol, or D2, is derived from fungal and plant sources. Rats can use it, but for humans it can be detrimental especially in higher amounts. D3 should be the choice.
The great balance idea comes into play here too. Studies are showing that sun exposure increases risk of some viruses, specifically human papillomavirus (HPV), which than increases the incidence of cervical cancer. A high incidence occurs in August in the Northern Hemisphere. Why? People tend to be out in the sun more during summer, thus getting more vitamin D. A classic Dr. Royal Lee statement is that Vitamin D tends to put calcium in the blood, vitamin C (the complex) tends to put calcium in the bone, and quality fatty acids tends to put calcium in the tissue. Lack of calcium relates to increasing the incidence of viruses, and secondarily a related incidence of some cancers.
Some claim using sunscreen can be more harmful than beneficial. The best way to prevent sunburn is to gradually acclimate to it. The use of quality dietary oils, not hydrogenated etc, help keep calcium in the tissue to help in healthy skin. (Cataplex® F for essential fats (plus a few other factors) and Calcium Lactate® from Standard Process® are an excellent combination in this regard.)
For blood tests, 1,25(OH)2D may have more meaning than the commonly done 25(OH)D test.
