Bromelain

Ingredients

Bromelain is a group of protein-digesting enzymes (proteases) naturally found in the stem and fruit of pineapple (Ananas comosus). Supplement-grade bromelain may be derived from pineapple stem and is commonly standardized according to enzyme activity, often expressed in units such as GDU or MCU. The exact source, enzyme activity, serving size, and additional ingredients vary by manufacturer.

Bromelain is a natural mixture of proteolytic enzymes obtained from pineapple (Ananas comosus). These enzymes help break down proteins and are commonly used as ingredients in digestive enzyme and nutritional supplement formulations.

Bromelain is particularly associated with the pineapple stem, which can provide a concentrated source of proteolytic enzymes. Some products may use bromelain from pineapple fruit or combine bromelain with other digestive enzymes.

Unlike many vitamins and minerals, bromelain is typically described by its enzyme activity rather than simply its weight. Product labels may use activity measurements such as GDU (gelatin digesting units) or MCU (milk clotting units). Therefore, two products containing the same milligram amount may have different enzyme activity.

Bromelain is available in capsules, tablets, powders, and combination enzyme formulas. People taking blood-thinning medication, those with pineapple allergies, or individuals preparing for surgery should consult a healthcare professional before using concentrated bromelain supplements.
