Bromelain is a group of protein-digesting enzymes found naturally in pineapple, mostly in the stem and also in the fruit. Fresh pineapple contains some, and it is why the fruit can tingle your mouth. Cooking and canning largely deactivate the enzyme.
If pineapple has ever made your tongue tingle, you have met bromelain. Here is what this enzyme is, where it lives in the fruit, and how it relates to food and supplements.
Bromelain is a mixture of enzymes called proteases, which break down proteins. In the pineapple plant, the highest concentration is in the stem, and a smaller amount is in the juicy flesh and core. This is the reason pineapple can leave a slightly raw or tingly feeling on your lips and tongue, as the enzyme starts digesting proteins on contact. The sensation is stronger with underripe fruit and when you eat a lot in one sitting. Pairing pineapple with yogurt or cottage cheese, or eating it after a meal, can soften the effect, because the enzyme then has other proteins to work on.
Fresh pineapple contains active bromelain, and that is why it works as a meat tenderizer in marinades. It is also why fresh pineapple prevents gelatin from setting, since the enzyme breaks down the protein. Heat changes the story: canned pineapple and cooked pineapple have been heated enough to deactivate most of the enzyme, so gelatin sets normally. Try grilling pineapple slices for a sweet, caramelized side, or blend fresh pineapple into smoothies. For marinades, thirty minutes is usually plenty, because leaving meat in fresh pineapple too long makes the texture turn mushy rather than tender, which is bromelain doing its job a little too well.

Check Today's PriceThe amount of bromelain in a serving of fresh fruit is small compared with concentrated supplements, which are measured in activity units such as GDU. Eating pineapple is still a tasty way to add vitamin C, manganese, and fiber. People with pineapple or latex allergies, those taking blood thinners or certain antibiotics, and anyone pregnant should ask a healthcare professional before using bromelain supplements. Choose ripe pineapples that smell sweet at the base and feel heavy for their size. Once cut, store the fruit in the refrigerator and eat it within a few days. Supplements should be kept in a cool, dry place and used according to their label directions.
BreathiZen includes bromelain standardized to 2400 GDU/g, alongside mullein leaf extract, ginger root extract, organic lemon extract, and Cordyceps militaris. It is a plant-based oral spray taken once daily to support respiratory wellness. Fresh pineapple remains a delicious food choice, but the two are different, since a daily spray is designed for consistent, gradual use. Your enzyme-rich diet and a daily habit complement each other. It is made in a GMP-certified, FDA-registered US facility, is non-GMO and non-habit-forming, and is a dietary supplement meant to support, not treat or cure.
Very little active bromelain remains. The heat used in canning deactivates most of the enzyme. Canned pineapple still offers vitamin C and fiber, though it is often packed in syrup, so choose fruit packed in juice or water.
Bromelain breaks down proteins, including those on the surface of your tongue and lips, causing a mild tingling or sore feeling. It is usually harmless and temporary. Allergic reactions are different and involve swelling or rash.
