Public Health England published new advice this week on vitamin D intake; recommending now that everyone takes a 10mcg (400IU) vitamin D supplement through the autumn and winter and also through the summer if they have little or no exposure to the sun. A ‘safe intake’ recommendation is given for babies 0-1 year (rather than an RNI (recommended nutrient intake) as there was insufficient evidence to set an RNI in this age group) of 8.5-10mcg including those who are exclusively or partially breast fed. Babies who are taking more than 500ml formula will not need extra supplements as formulas are fortified already. The ‘safe intake’ recommendation of 10mcg also applies to 1-4 year olds. NHS Choices also give a good summary here. This is a change to previous advice which had only recommended supplementation in at risk groups.
