EFSA recommends significant increase in the upper safe limit for vitamin D
The European Food Safety Authority, (EFSA) increases their guidelines on the upper safe limit for vitamin D.
In 2002, EFSA evaluated the upper safe limit for intake of vitamin D to be 50 micrograms a day. It is this limit EFSA has been asked to reevaluate based on a series of new research findings. EFSA is basing their evaluation on two studies of men who consumed between 234 and 275 microgram vitamin D a day without gaining an increased content of calcium in the blood, (a side effect of vitamin D toxicity).
To guard against possible uncertainties in these studies, EFSA has proposed that the safe limit is set to 100 micrograms daily, which is a significant increase in the previous assessment.
Existing limit values are still valid
In European countries the recommended daily allowance (RDA) is around 5 micrograms for adults and 5-10 micrograms for children and elderly people. If the new recommendations from EFSA are approved by the EU Commission it can mean a significant change in the European recommendations.
EFSA's proposal is as follows:
|Age children||Upper safe level for ingestion (UL) of the vitamin D (µg / day)|
|0-1 years||25 micrograms|
|1-10 years||50 micrograms|
|11-17 years||100 micrograms|
|Adults ≥ 18 years (including pregnant and nursing)||100 micrograms|
