Personalized Vitamin D: The Key to Effective Supplementation

"Time is no longer the enemy; it's the path to full longevity. Personalization is the bridge between knowledge and comprehensive well-being."

A recent study, published in the prestigious scientific journal Clinical Nutrition in April 2025, reveals that the key to effective vitamin D supplementation is personalized treatment. The study, conducted by researchers at the Cleveland Clinic and the University of Catania (Italy), analyzed the impact of tailoring vitamin D doses to each individual's initial levels, rather than following standardized regimens.

The study concludes that personalizing vitamin D supplementation is much more effective than applying generic doses. Measuring 25OHD levels before treatment provides a strategy that improves absorption and effectiveness, tailoring it to individual needs. This is particularly essential for older adults, those with obesity, or those at specific risk.

At Longevitas, this philosophy of personalization is already a reality. We use advanced tools such as biogenetic studies and recommendations based on blood and DNA analysis to create personalized supplementation plans. It's not just about offering vitamin D, but about offering your vitamin D: the exact dose, frequency, and combination your body needs.

Furthermore, we understand that vitamin D is much more than just bone health. Its influence on immune function, metabolism, and inflammation regulation makes this vitamin a key component for longevity. And only with a personalized strategy can we ensure its optimal effect.
