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.

Got SAD? Got ODD? Here's News You Can Use

Posted by Candace Burch on Wednesday, 10 February

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. Isn't there something they do to stay happy in the absence of the sun? Not really. "We just deal with it! Polar People don't mind!" (Hersher, 2016).

But if you are not one of the "Polar People" and looking for a solution to flagging mood and energy—especially if it occurs during the fall and winter monthsyou probably do mind, very much. In that case, the possibility that you are deficient in Vitamin D should be a top consideration. (Consider that the Inuit diet is very unusual compared to ours, given that they eat plenty of fatty sea food that is super rich in vitamin D.)

New Research on Vitamin D Using Dried Blood Spot Testing

Posted by Margaret Groves on Thursday, 23 April

Vitamin DTwo vitamin D studies were published recently, both utilizing ZRT's testing in dried blood spot.

Dried blood spot samples are well suited for research applications because they are equivalent to serum but have the advantage of ease of sample collection, shipping, and storage, which doesn’t require any refrigeration or biohazard labeling. Also, samples are easily identified by details that can simply be written on the outside flap of the collection cards, which require minimal freezer space for long-term storage of samples.

The Phenomenon of Vitamin D

Posted by Dr. Sherry LaBeck on Monday, 12 January

 

155036913-597007-editedEarly in the 20th century, research in the nutritional arena was blossoming. Scientists were swiftly realizing that the nutritional requirements to "support life, growth and reproduction" in both animals and humans were more than simply proteins, carbohydrates, fats and minerals, as commonly believed. And, all scientists working in the field knew that this missing knowledge was key to relieving a host of common afflictions.

In 1912 one scientist, Casimir Funk, isolated a substance found in the hulls of rice that cured beriberi, a nutritional disease linked to thiamine (B1) deficiency. From this revelation, he theorized that other diet-related ailments such as pellagra, scurvy and rickets could also be a consequence of deficiencies of yet unidentified substances. He further hypothesized that these substances would have the same basic property of a protein, and called them "vital amines" or "vitamines" Later this term was embraced (with the ‘e’ omitted) and became a major focus of nutritional research for the next 30 years, yielding discovery after discovery of essential nutrients.
