The Mood Boosting Probiotic, The Science Behind L. brevis

Lactobacillus brevis or L. brevis belongs to the lactic acid bacteria family. In addition to improving gut health, L. brevis is also linked to having a positive effect on your mood.¹

L. brevis is commonly found in fermented food products like sauerkraut, pickles and yogurt, and added in certain wines and beers for flavor.

According to studies, L. brevis may support natural killer (NK) cell activity in adults.² NK cells are a type of pathogen-killing cells that fight off infections and stop the growth of cancer cells.

Doctor's Biome contains live, active cultures of L. brevis, along with 14 other scientifically backed strains of probiotics. We suggest taking Doctor's Biome on an empty stomach or at least 30-60 minutes before a meal for optimal health boosting results.
