I don't know about which you are talking about, but if you are talking about the Government jobs as Nutritional Therapist, then yeah! The state governments sometimes releases notification for Nutritional Therapist and for that one need to have MSc along with the qualification of Registration in Nutrition and Dietetics. The age limit is not specific and is dependent on the government but in general the maximum age limit is 40 years for most of the State Governments.
