Plasmolysed herbal yeast (Strath®) improves micronutrient bioavailability – An in vitro study using Caco-2 intestinal epithelial cells

The use of yeasts enriched with distinct micronutrients as supplement in human nutrition increased over the last years. A special plasmolysed herbal yeast was investigated to demonstrate its beneficial effect on the bioavailability of important micronutrients for human nutrition such as iron, zinc, magnesium and vitamin B1. The well-established Caco-2 model was applied for this investigation. The plasmolysed herbal yeast underwent an in vitro simulation of the gastro-intestinal digest process before applied to the Caco-2 model. The results demonstrate an improved bioavailability of the micronutrients iron, zinc, magnesium and vitamin B1 in the presence of the plasmolysed herbal yeast.
