HCL Breakthrough provides you with a plethora of digestion-related benefits, that facilitate better gut movement and release of stomach acid. But other branded supplements that are meant for gut support do not have such benefits. They might improve your digestion but not on a long-term basis. It is 100 percent plant-based. Even the pepsin contained in this supplement is made from plant-based substances and not from animals. But other brands add animal-based ingredients as pepsin to their supplements, making it inappropriate for consumption by certain individuals.
