What are Oral Nutrition Supplements?

Oral nutrition supplements (ONS) are foods and drinks that provide extra nutrition to help prevent or treat malnutrition. They contain energy (calories), protein, vitamins, and minerals for people who cannot get enough nutrition from their usual diet.
They come in many forms, which include
  • milkshake style drinks
  • juices
  • powders
  • ready-made liquids.
Some products are tailored for people with dysphagia (swallowing difficulties).
