vit A and folic acid for SAM treatment in adults who are on PlumpyNut?

Dear experts I would very much appreciate your inputs on this question: I have male adults who are SAM (based on BMI or oedema). They receive 5 sachets of Plumpynut and a simple meal per day. Should they receive a high dose of vitamin A: yes/no and why? Should they receive a dose of folic acid: yes/no and why? Your (scientific) opinion is more than appreciated! Thanks so much, Mija
