Composition of Immunace micronutrient supplement produced by Vitabiotics, compared to reference nutrient intake (RNI) for British adults (men or women, whichever is the higher). *Equivalent to 700 μg/day retinol, which is the RNI for adult men. ^†Based on RNI for older adults, no intake of preformed vitamin D can be quantified as required for adults exposed to sun.

The corrected table is as follows.
