I am malnourished and would like to gain weight. What is suitable for this: Nutrego Forte, Nutridrink or Nutricomp drink?

It is difficult to suggest a specific method of treatment based on such a short description.

Nutrego Forte, Nutridrink and Nutricomp Drink are ready-to-eat high-calorie, high-protein and low-residue diets. They differ in calorific value, osmolality and protein content. All of these preparations should be used under medical supervision.

I encourage you to make an appointment with your doctor or dietitian, who will adjust the treatment according to your current clinical condition. If you do not have the opportunity to consult your doctor, you can use the teleconsultation here:
