- Vitamin D: A Sufficient Blood Level is Necessary for Optimal Health
Vitamin D knowledge has undergone a fascinating evolution over the years. First, there was the general understanding that deficiency of this secosteroid hormone was the cause of the childhood disease known as rickets and later, it became known as the key to good bone health; now, there is an acknowledgment that vitamin D is necessary for humans to maintain optimal ...
- Defining Safety: Tanning, Sunscreens, Vitamin D Supplements and Botox
The recent firestorm of anti-tanning propaganda featuring the false and misleading claim that “there is no such thing as a safe tan” caused us to wonder how tanning compares to sunscreens, vitamin D supplements and Botox injections with regard to safety. But, in order to make this comparison, we must first define the words “safe” and “tan.”“Safe” can be defined ...
- Study: Sun Exposure May Have Anti-Melanoma Effect Through Vitamin D
A new study indicates an association between skin cancer and Bsml, a receptor gene involved in vitamin D metabolism. The study, which will be published in the journal Cancer, suggests that genetic differences in Bsml are the reason that people have different levels of vitamin D, and that this means some people may have more vitamin D-related protection against cancer ...
- Science & Technology: Melanoma, Tanning Part 2
In Part 1 of this series, we showed that there is no causal correlation between UVR and cutaneous malignant melanoma (CMM). Instead, we showed that a weak coincidental correlation resulting from the normal and natural response by the body to UVR (an increase in the number of melanocytes in the skin after exposure) has led to the incorrect belief that ...
- Science & Technology: Melanoma & Tanning
Does exposure to sunlight, UVR or a tanning device cause cutaneous malignant melanoma (CMM)? The answer to this question is extremely important to the indoor tanning industry because, if UVR can be scientifically proven to cause CMM in humans, the survival of the industry is in jeopardy. On the other hand, if the scientific evidence shows that exposure to sunlight, ...
