Biogena Griffonia 50 Serolution contains the amino acids 5-HTP from Griffonia simplicifolia and phenylalanine, both precursors of the "happiness hormone" serotonin, along with special B vitamins, amino acids, and extract from the acerola cherry. 5-HTP is a natural intermediate product in the body from which serotonin is formed. Serotonin levels are closely linked to a positive mood and a feeling of satisfaction. Biogena Griffonia 50 Serolution can support your well-being during stressful situations.
