Researchers believe their findings have significant implications for the development of tailored recommendations for vitamin D supplementation.
The authors analysed data from half a million participants from the United Kingdom and for each person, they calculated the individualized estimate of ambient ultraviolet-B level, which is the wavelength of sunlight that induces vitamin D synthesis in the skin. "We believe our findings have significant implications for the development of tailored recommendations for vitamin D supplementation. Our study underscores the need to move away from a one-size-fits-all approach towards personalized strategies for optimizing vitamin D status."
