1. calcium maybe? I dunno. Just google milk vitamins.
2. There is less vitamin A in skimmed milk than in whole milk. This is because the vitamin is in the fat part of the milk. There is less fat in skimmed milk, and so there is less vitamin A. See: http://www.milk.co.uk/page.aspx?intPageID=71 from the Dairy Council. RNI (Reference Nutrient Intake) values are rough estimates based on existing research. The RNI is considered to be enough to meet the requirements of most people and is generally more than most of us need. This is because the amount of vitamins needed depends on age, gender, size and general health.

3. Vitamin A which is a fat soluble vitamin (hence it is reduced when fat content lessened.) See The Dairy Council website answer as follows: 'Whole milk contains some vitamin A, however levels in semi skimmed and skimmed milks are much lower. This is because vitamin A is dissolved within the milk fat fraction which is removed to varying levels when producing lower fat milk products.' Adults will get rid of excess vitamins that they have not used on a daily basis and if a ctain amount of a vitamin is present in their body already, they will not need as much as quoted for the RNI values.
