Vitamin D: Daily Intake for Adults Under 75

New guidelines clarify the daily intake recommendations for vitamin D for adults under 75. Healthy individuals in this age group likely don’t require extra vitamin D supplementation, and routine testing isn’t advised. These updated recommendations, published in The Journal of Clinical Endocrinology & Metabolism, emphasize the nuanced role of vitamin D in overall health. Experts suggest higher doses for children, pregnant individuals, and older adults, but not necessarily for those under 75. The focus is on disease prevention. News Directory 3 provides critical insights on this topic. The expert panel highlights limitations in current evidence, notably on establishing specific blood level thresholds. Discover what’s next …
New Vitamin D Guidelines Address Supplementation Role and testing
New guidelines from the Endocrine Society address the appropriate use of vitamin D supplements and testing. The recommendations, published in the August 2024 issue of The Journal of Clinical Endocrinology & Metabolism, suggest that healthy adults younger than 75 are unlikely to benefit from exceeding the Institutes of Medicine’s (IOM) recommended daily intake. Routine vitamin D level testing is also discouraged for this group.
Though, the guidelines suggest higher vitamin D doses than the IOM’s daily allowance for children, pregnant individuals, adults over 75, and those with high-risk prediabetes. The panel of experts based their recommendations on clinical trials, focusing on healthy individuals without specific indications for vitamin D treatment or testing.
marie Demay, M.D., of Harvard Medical School and Massachusetts general Hospital, who chaired the guideline panel, said the aim was to define vitamin D requirements for disease prevention in generally healthy people.She noted that while higher doses might benefit those 75 and older, pregnant people, adults with prediabetes, and children and adolescents, routine vitamin D level testing isn’t advised for any of these groups.
for adults 50 and older needing vitamin D supplementation, the guidelines favor daily, lower doses over less frequent, higher doses. The panel also advises against routine 25-hydroxyvitamin D level testing, including screening for people with dark complexions or obesity, citing a lack of identified outcome-specific benefits based on these levels.

what’s next
Researchers continue to explore the role of vitamin D in various health outcomes, but the panel acknowledged limitations in current evidence. Many large clinical trials weren’t designed for the reported outcomes, and studied populations often had adequate vitamin D blood levels at the outset. The panel couldn’t establish specific blood-level thresholds for adequacy or target levels for disease prevention due to insufficient evidence regarding the role of vitamin D supplementation and vitamin D levels.
