Bromelain
Description:
Bromelain, derived from the pineapple plant, is one of a group of proteolytic enzymes (enzymes capable of digesting protein).
Properties & Uses:
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.
Recommended Dietary Allowances:
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.
Deficiency Symptoms:
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
