Prolife lozenges are a nutritional supplement with live bacterial cultures and B group vitamins. Live bacterial cultures, so-called 'good bacteria', maintain or restore the balance of disturbed intestinal microflora. Glucooligosaccharide is a prebiotic and enables the colonization ('inhabitation') and reproduction of good bacteria. Vitamins B6 and B12 contribute to the normal functioning of the immune system and reduce fatigue, especially during periods of intense physical and mental activity. Vitamins B1 and B2 contribute to normal energy production.
