Now that we are heading towards summer in Australia, most of us think about slathering our bodies with sunscreens, but if we were to expose at least 20% of our skin to sunlight all year round for up to 10 minutes a day without any sunscreen, then many of us would ensure adequate amounts of vitamin D (remember to do this before the hottest part of the day – early morning or late afternoon).
The liver and kidney help convert vitamin D to its active hormone form. Those who have impaired liver or kidney functions would require more vitamin D synthesis either from direct sunlight or good quality supplements. (Note: a simple blood test may be required to check your current levels of vitamin D before considering any supplementation.)
Deficiency of natural sunlight and vitamin D has been associated with seasonal affective disorder (SAD). Dr. Norman Shealy, M.D.,Ph.D wrote that Vitamin D has long been known to enhance immune function and to benefit many other health conditions.
Krispin Sullivan from the Weston A. Price Foundation writes “Actually, vitamin D does not in itself promote healthy bone. Vitamin D controls the levels of calcium in the blood. If there is not enough calcium in the diet, then it will be drawn from the bone. High levels of vitamin D (from the diet or from sunlight) will actually demineralize bone if sufficient calcium is not present.
Vitamin D will also enhance the uptake of toxic metals like lead, cadmium, aluminum and strontium if calcium, magnesium and phosphorus are not present in adequate amounts. Vitamin D supplementation should never be suggested unless calcium intake is sufficient or supplemented at the same time”. See the complete article below.
“The existence and importance of this part of our immune response makes it clear that humans and other primates need to maintain sufficient levels of vitamin D,” said Adrian Gombart, an associate professor of biochemistry and a principal investigator with the Linus Pauling Institute at Oregon State University.
