Probulin is a probiotic brand built around one powerful differentiator: their patented MAKTrek 3-D Probiotic Delivery System. Most probiotic supplements lose a significant portion of their live bacteria to stomach acid before reaching the intestines where they do their work. Probulin's triple-layer MAKTrek technology — using a marine polysaccharide seaweed coating and a secondary protective acid buffer — shields probiotic bacteria through the harsh stomach environment, delivering far more live cultures to the colon. NSF certified and third-party tested, Probulin offers formulas for daily support, women's health, mood, and colon health. Every Probulin product is refrigerated for guaranteed potency and is free from dairy, gluten, and soy — delivering probiotics that actually survive the journey.
