The
term "proteolytic" refers to all enzymes that
digest protein. Other classes of enzymes include Amylase
a digestive enzyme that breaks down carbohydrates and Lipase
a digestive enzyme that breaks down fat during the digestive
process. Each of these help in the digestion of food which
in turn helps with absorption of those essential nutrients
in the diet. In the body, proteolytic digestive enzymes
are produced in the pancreas, but supplemental forms of
enzymes may come from fungal or bacterial sources, extraction
from the pancreas of livestock animals (trypsin/chymotrypsin)
or extraction from plants (such as papain from the papaya
and Bromelain from pineapples). The primary uses of proteolytic
enzymes in dietary supplements are used as digestive enzymes,
anti-inflammatory agents and pain relievers.
There
are a number of clinical trials showing the benefit of using
oral proteolytic enzymes as a digestive aid. Proteolytic
enzymes are also theorized to help reduce symptoms of food
allergies and as a treatment for rheumatoid arthritis and
other autoimmune diseases
Perhaps
the strongest evidence for benefits of proteolytic enzyme
supplements come from numerous European studies showing
various enzyme blends to be effective in accelerating recovery
from exercise and injury in sportsmen as well as tissue
repair in patients following surgery. In one study of footballers
suffering from ankle injuries, proteolytic enzyme supplements
accelerated healing and got players back on the field about
50% faster than athletes assigned to receive a placebo tablet(1).
A handful of other small trials in athletes have shown enzymes
can help reduce inflammation, speed healing of bruises and
other tissue injuries (including fractures) and reduce overall
recovery time when compared to athletes taking a placebo(2-8).
In patients recovering from facial and various reconstructive
surgeries, treatment with proteolytic enzymes significantly
reduced swelling, bruising and stiffness compared to placebo
groups (9-11).
