Is it harder to absorb vitamin D as you get older? An in-depth look at age-related factors

According to the Cleveland Clinic, the ability of human skin to produce vitamin D decreases significantly with age, with a reduction of over 50% in the precursor compound from age 20 to 80. This critical decline directly contributes to why it is harder to absorb vitamin D as you get older, but it's not the only reason. Multiple physiological changes, including diminished skin synthesis, altered metabolism, and lifestyle factors, compound the challenge of maintaining adequate vitamin D levels in later years.
