ADVERSE EFFECTS
In the present study, the 4-week intake of REP hydrolysate did not show a positive effect, possibly due to the insufficient length of intervention. The single intake of REP hydrolysate did not improve the Euthymia Scale or all of the subscales of POMS 2; yet, it showed a significant improvement in the POMS 2 Tension–Anxiety score and a significant reduction in the salivary CgA concentration without adverse effects. Hence, REP hydrolysate may be a helpful and harmless ingredient that can be used to relax anxiety symptoms and nervousness and prevent future related symptoms.
