The amino acids can be used to supplement both sip and tube feeding. They are soluble in water and can be added directly to liquid or powdered formula. They are best added to the powder before reconstitution. They may also be taken as a paste. Flavouring can be added if required. The addition of flavourings to foods for infants under 6 months is not recommended.
