Bromelain for Sports & Fitness
What is it?
Bromelain, derived from the pineapple plant, is one of a group of proteolytic enzymes (enzymes capable of digesting protein).
Where is it found?
Bromelain is found mostly in the stems of pineapples and is available as a dietary
supplement.
Why do athletes use it?*
Some athletes say that bromelain
- helps to reduce pain associated with sports injuries,
such as sprains and strains.
What do the advocates say?*
Bromelain is most effective for injuries in which there is a congestion of blood or heavy
bruising. Because it is a protein digestive agent, bromelain digests trapped blood byproducts.
It is more effective for sprains and strains than it is for joint pain.
When using bromelain, continue to take it until the swelling and blood stagnation is gone;
this can last anywhere from a few days to a few weeks.
How much is usually taken by athletes?
Typically, 2 to 4 tablets or capsules are taken several times per day. Other uses of
bromelain for sports and fitness have not been studied.
Are there any side effects or interactions?
Bromelain is generally safe and free of side effects when taken in moderate amounts.
However, one preliminary report indicates increased heart rate with the use of
bromelain.1 In addition, some people are allergic to bromelain. One woman
reportedly developed a hives and severe swelling after taking bromelain, even though she had
tolerated bromelain on two other occasions previously.2 Because bromelain acts as a
blood thinner and little is known about how bromelain interacts with blood-thinning drugs,
people should avoid combining such drugs with bromelain in order to reduce the theoretical
risk of excessive bleeding.
Are there any drug
interactions?
Certain medicines may interact with bromelain. Refer to drug interactions for a list of those medicines.
