Bifidobacterium bifidum (CUL 20) resists stomach acid and reaches the intestines intact. Clinically studied, this strain settles into the gut lining where it helps maintain a strong gut barrier and keeps immune responses balanced.
Many people find that CUL 20 promotes regular bowel movements and soothes occasional digestive upset. Take it alongside a meal to boost its survival through the digestive tract. You will find it sold as a single strain capsule or inside multi-strain probiotic blends.
Mild bloating or gas can happen during the first few days of use. Anyone with a weakened immune system or a serious health condition should speak with a doctor before starting. To keep the bacteria alive, allow at least two hours between a dose of antibiotics and this probiotic.
