• Vitamin D's many health benefits highlighted in studies from the major medical journals: hormonal balance for men and women; fibroids; healthy blood pressure; diabetes; multiple sclerosis; chronic back back pain; reduction in pain in older people with overall body pain; less falls; immune support; helps our bodies make their own antibiotics; and many, many other health benefits.

• "25-OH is the health test to check your levels, 60-100 ng = the optimal health level."
• "The sun doesn't cause skin cancer (the risk is much lower for the worst kind of skin cancer, melanoma) if you are eating healthfully, (nutrient dense) Mediterranean Diet -- 140 studies cited, melanoma increased 12 fold on the Standard American Diet (SAD)."
• "Sunscreen doesn't appear to help prevent skin cancer."

• Information on Vitamin D from Krauss' Food and the Nutrition Care Process, a Dietetics Textbook:
  • "The skin not only makes vitamin D upon exposure to UVB rays [from sunlight], but also makes other photoproducts that cannot be obtained from food or supplements."
  • "UVB light cannot pass through glass; exposure of the skin to sunlight through glass will not result in vitamin D synthesis."
  • "Another deterrent to vitamin D synthesis by the skin is sunscreen. A sunscreen with an SPF 15 reduces skin synthesis of vitamin D by 95%, and an SPF 30 reduces it by 99%."
  • "How much sun exposure is the correct amount to maintain optimal vitamin D levels in the body? A person sunbathing in a bathing suit will have received a dose of between 10,000 and 25,000 IU [the RDA for adults 19 to 70+ is 600 to 800 IU] when he or she has sunbathed long enough to be slightly pink 24 hours later ... Exposing 25% of the body (arms and legs) for 1/4 to 1/2 the time it takes to get slightly pink will allow the body to make 2,000 to 4,000 IU of vitamin D with each exposure."
  • "The amount of time necessary for sunlight exposure to produce adequate vitamin D depends on the person's skin type (pale skin requires less time than dark skin with a lot of the burn-protecting pigment melanin), season of the year (the lower the sun on the horizon in the winter, the greater the time needed), the latitude (within + or - 35 degrees from the equator, the most vitamin D can be produced when skin is exposed to UVB rays), and the time of day (more vitamin D is synthesized by the skin when the sun is directly overhead between 11:00 AM and 3:00 PM)."
  • "A person should be exposed to sunlight 2 to 3 times per week from March through October in northern climates to accumulate enough vitamin D to get through the winter with adequate vitamin D. See Holick for tables [Vitamin D: A D-lightful Solution for Health, Dr. Holick's website] of time of sun exposure needed to make adequate amounts of vitamin D. Several apps are also available to determine this -- Vitamin D Calculator, Vitamin D Pro, and D-Minder."
  • "Beside being in bone, receptors for vitamin D have been identified in the gastrointestinal track, brain, breast, nerve, and many other tissues."
  • "Vitamin D maintains adequate serum calcium and phosphate concentrations to prevent hypocalcemic tetany [overly stimulated neuromuscular activity]. It also modulates cell growth, neuromuscular and immune function, and reduction of inflammation. Many genes that encode for the regulation of cell proliferation, differentiation and apoptosis are modulated by vitamin D... https://ods.od.nih.gov/factsheets/vitaminD-HealthProfessional/."
