Survey results: vitamin D supplementation & vD RDA


"These are the preliminary results of the vitamin D supplementation survey. It is clear that the variable recommended daily allowance (RDA) information is confusing you. What can be done about it?"

"I am reassured to note that those of you who responded to the question on what we recommend on this blog ticked either 5,000U or 4,000U per day. The 5,000U comes from  the Vitamin D Council's recommendation and the 4,000U from the European Food Safety Authority (EFSA). Which one is correct? They are both fine; I still recommend the 5,000U per day for economic reasons; in the UK General Practitioners or GPs, generally will not prescribe these doses and 5,000U tablets are much cheaper than 4x1,000U or 2x2,000U tablets. In additon, the 5,000U per day dose is well within the safe daily dose of vD supplementation of EFSA, i.e. 11,000U per day."
