What is a Probiotic?
Poor diet, antibiotic use, stress, illness, food poisoning and traveling can deplete the beneficial bacteria that fill our digestive systems. Probiotics help to maintain and improve the balance of beneficial flora to support healthy digestive and immune systems. GNC's clinically studied probiotic formulas are tested to ensure the highest potency, delivering up to 1500% more live and active cultures per serving than leading competitors.
