Most probiotics never make it to your gut

Stomach acid destroys the majority of live cultures in ordinary probiotics before they can do a thing. That's the dirty secret of the category — high CFU counts on the label mean nothing if the bacteria die on the way down.

THE DIFFERENCE

MAKTrek® 3-D Probiotic Delivery System

Our capsules use a marine-derived, seaweed-based delivery technology that shields live cultures from stomach acid — so the full 40 billion CFU actually survives to reach your intestines, where it belongs.

Survival is the whole game. That's what you're paying for.
