Quick Takeaway: Studies suggest high blood levels of 25-OH vitamin D may prevent melanoma [1] and appropriate D levels may affect the prognosis in both primary [2] and metastatic melanomas. [3] Keep your levels in blood between 50-80 ng/dL.

Additionally, melatonin and its metabolites protect the skin from sun and help guard the DNA there when faced with the mixture of cancer-inducing ultraviolet rays and oxidation.

ThinkstockPhotos-458916339-667252-edited.jpgOn Nov. 24, the sun set in the tiny Greenlandic town of Ittoqqortoormiit. For the next three months, the Inuit inhabitants of this isolated, icebound landscape will take their children to school in the dark, work in the dark, and pick them up in the dark.

And though townspeople admit that, "it can get depressing for people who weren't born here, especially in December," the local mindset is that living in darkness is just a normal part of life.

Last week, I discussed Melatonin's Role in Sleep. By focusing on MT6s, we may be focusing on the tip of the melatonin iceberg.

We see very high levels of MT6s in the urine as a result of pineal synthesis and release of melatonin in response to dark stimulation.

Melatonin's Role in Sleep

Posted by Dr. Allison Smith on Saturday, 07 March

139247884Melatonin is a ubiquitous little hormone that comes in an indolamine package similar to serotonin, its precursor. Thanks to its unique structure, it can travel easily through the blood stream and readily crosses the blood-brain and placental barriers. It is synthesized and used all over the body to perform a number of indispensable roles. It’s the main reason our bodies know what time it is and what it’s supposed to be doing at any given moment.
