Isovaleric Acidaemia (IVA) | Protein metabolism

Isovaleric acidaemia (IVA)

Isovaleric Acidaemia (IVA) 

The ‘building blocks’ of protein are called amino acids. Isovaleric acidaemia (IVA), is one of a number of disorders where, due to the lack of an enzyme, the body cannot properly deal with one of the amino acids, leucine. People with IVA therefore need to restrict the amount of protein they eat.


Protein substitutes for IVA and related disorders, provide all the amino acids found in protein but no leucine. In combination with their allowance of regular dietary protein, protein substitutes ensure that an individual with IVA has an adequate intake of protein.


Vitaflo® produces a ready-to-drink, lifestyle-friendly protein substitute for IVA.
