Invertase is a microbial enzyme sourced from yeast or fungi. It splits sucrose into glucose and fructose. Commercial invertase is not the same as the sucrase your body makes at the intestinal brush border. No solid evidence shows that oral invertase helps human sucrose digestion the way sacrosidase (recombinant human sucrase) does.
Some people take invertase for its sucrose-splitting action in the lab, but the enzyme is not built for human digestive shortfalls. Relying on it can delay proper treatment for conditions like congenital sucrase-isomaltase deficiency.
This product is not a substitute for clinical sucrase therapy.
