Bromelain is a proteolytic enzyme derived from the stem of the pineapple that has protein-digesting properties. Proteases like bromelain break down the protein you get from food and turns it into amino acids. Your body then uses these amino acids for various functions. Bromelain can deliver outstanding support for comfortable joint function, as well. Swanson Ultra Bromelain veggie caps feature super-potent bromelain in a delayed-release veggie cap that enables it to pass through the stomach without losing its enzymatic activity, delivering a powerful 1,200 GDU to be absorbed in the lower gastrointestinal tract for optimal systemic activity.
