New Vitamin D Guidelines Scrap Routine Testing for Healthy Adults Under 75

New guidance on vitamin D intake and testing has been issued for different age groups. An article in Eesti Arst by endocrinologist Vallo Volke states that healthy adults under 75 do not require routine supplementation or blood checks. Meanwhile, updated U.S. guidelines have adjusted the normal threshold for vitamin D levels.

Endocrinologist Vallo Volke’s 2024 article highlights that regular vitamin D intake and testing are unnecessary for adults under 75. Doctors may still order tests if they suspect a deficiency or see a medical need. The decision remains at the physician’s discretion.

The Health Insurance Fund supports this stance, advising against routine vitamin D level checks in standard blood tests. For healthy adults, supplementation is only recommended when deficiency is suspected. However, certain groups are advised to take vitamin D supplements regardless. Children, adolescents, pregnant women, and those aged 75 and older should maintain intake. For the elderly, supplementation is encouraged without the need for regular blood monitoring. The U.S. Endocrine Society recently updated its guidelines, lowering the normal vitamin D threshold to 50 nmol/L. Previously, the benchmark had been set below 75 nmol/L. Despite widespread supplement use and increased testing, the optimal dose and serum concentration for disease prevention remain unclear.

The updated recommendations aim to streamline vitamin D testing and intake. Healthy adults under 75 no longer need routine checks, while specific groups continue to receive supplementation advice. Doctors retain the authority to request tests when clinically justified.
