Digestive Enzymes

Uses

Digestive enzymes are complex proteins involved in digestion that stimulate chemical changes in other substances. They work optimally at specific temperature and pH. Digestive enzymes include pancreatic enzymes, plant-derived enzymes, and fungal-derived enzymes. There are three classes of digestive enzymes: proteolytic enzymes needed to digest protein, lipases needed to digest fat, and amylases needed to digest carbohydrates.

Used forWhy
3 Stars
Low Back Pain (Trypsin, Chymotrypsin)
4 to 8 tablets a day of proteolytic enzymes containing trypsin and chymotrypsin, and/or bromelain
Supplementing with a combination of the enzymes trypsin and chymotrypsin may improve low back pain.

Three double-blind trials have investigated the effects of supplementing a combination of the trypsin and chymotrypsin for seven to ten days on severe low back pain with or without accompanying leg pain. Eight tablets per day were given initially in all trials, but in two trials the number of pills was reduced to four per day after two to three days. One of these trials reported small, though statistically significant improvements, for some measures in people with degenerative arthritis of the lower spine. People with sciatica-type leg pain had significant improvement in several measures in one trial, while another found the enzymes were not much more effective than a placebo. These trials included chronic low back conditions, so their relevance to acute LBP alone may be limited.

Pancreatic Insufficiency
Consult a qualified medical practitioner
Digestive enzymes are the mainstay of pancreatic insufficiency treatment and have been shown to reduce pain and steatorrhea associated with pancreatitis.

The mainstay of treatment for pancreatic insufficiency is replacement of , using supplements prepared from pig pancreas (pancrelipase) or fungi. Enzyme supplements have been shown to reduce steatorrhea associated with pancreatitis, while pain reduction has been demonstrated in some, though not all, double-blind studies. Digestive enzyme preparations that are resistant to the acidity of the stomach are effective at lower doses compared with conventional digestive enzyme preparations. Some enzyme preparations are produced with higher lipase enzyme content for improved fat absorption, but one controlled study of chronic pancreatitis found no advantage of this preparation over one with standard lipase content. People with more severe pancreatic insufficiency or who attempt to eat a higher-fat diet require more enzymes, but large amounts of pancreatic digestive enzymes are known to damage the large intestine in some people with diseases causing pancreatic insufficiency. Therefore, a qualified healthcare practitioner should be consulted about the appropriate and safe amount of enzymes to use.

Many otherwise healthy people suffer from indigestion, and some doctors believe that mild pancreatic insufficiency can be a cause of indigestion. A preliminary study of people with indigestion reported significant improvement in almost all of those given pancreatic enzyme supplements. One double-blind trial found that giving pancreatic enzymes to healthy people along with a high-fat meal reduced bloating, gas, and abdominal fullness following the meal.

Stomach surgery patients often have decreased pancreatic function, malabsorption, and abdominal symptoms, including steatorrhea, but digestive enzyme supplementation had no effect on steatorrhea in two of three double-blind studies of stomach surgery patients, although some other symptoms did improve. Patients who have surgery to remove part of the pancreas often have severe steatorrhea that is difficult to control with enzyme supplements. In one double-blind study, neither high-dose nor standard-dose pancreatin was able to eliminate steatorrhea in over half of the pancreas surgery patients studied.

Sprains and Strains
4 to 8 tablets a day of proteolytic enzymes containing trypsin, chymotrypsin, and/or bromelain
Proteolytic enzymes, including bromelain, may be helpful in healing sprains and strains because they are anti-inflammatory and appear to promote tissue healing.

Several preliminary trials have reported reduced pain and swelling, and/or faster healing in people with a variety of conditions using either bromelain, papain from papaya, or a combination of trypsin and chymotrypsin. Double-blind trials have reported faster recovery from athletic injuries, including sprains and strains, and earlier return to activity using eight tablets daily of trypsin/chymotrypsin, four to eight tablets daily of papain, eight tablets of bromelain (single-blind only), or a combination of these enzymes. However, one double-blind trial using eight tablets per day of trypsin/chymotrypsin to treat sprained ankles found no significant effect on swelling, bruising, or overall function.

Bromelain is measured in MCUs (milk clotting units) or GDUs (gelatin dissolving units). One GDU equals 1.5 MCU. Strong products contain at least 2,000 MCU (1,333 GDU) per gram (1,000 mg). A supplement containing 500 mg labeled “2,000 MCU per gram” would have 1,000 MCU of activity, because 500 mg is half a gram. Some doctors recommend 3,000 MCU taken three times per day for several days, followed by 2,000 MCU three times per day. Some of the research, however, uses smaller amounts, such as 2,000 MCU taken in divided amounts in the course of a day (500 MCU taken four times per day). Other enzyme preparations, such as trypsin/chymotrypsin, have different measuring units. Recommended use is typically two tablets four times per day on an empty stomach, but as with bromelain, the strength of trypsin/chymotrypsin tablets can vary significantly from product to product.

Celiac Disease
Consult a qualified healthcare practitioner
Some evidence suggests that enzyme supplements may be useful at the beginning of dietary treatment for this disease.

People with celiac disease often do not produce adequate digestive secretions from the pancreas, including lipase enzymes In a double-blind trial, children with celiac disease who received a supplement along with a gluten-free diet gained significantly more weight in the first month than those treated with only a gluten-free diet. However, this benefit disappeared in the second month, suggesting enzyme supplements may only be useful at the beginning of dietary treatment.

Indigestion, Heartburn, and Low Stomach Acidity
Consult a qualified healthcare practitioner
Lipase, a pancreatic enzyme, aids in the digestion of fats and may improve digestion in some people.

Lipase, a , aids in the digestion of fats and may improve digestion in some people. In a double-blind trial, a timed-release form of pancreatic enzymes was shown to significantly reduce gas, bloating, and fullness after a high-fat meal. Participants in this study took one capsule immediately before the meal and two capsules immediately after the meal. The three capsules together provided 30,000 USP units of lipase, 112,500 USP units of protease, and 99,600 USP units of amylase. However, the amount of pancreatic enzymes needed may vary from person to person, and should be determined with the help of a doctor.

Osteoarthritis
90 mg of bromelain and 48 mg of trypsin, with 100 mg of rutosid, taken in enteric-coated pills three times per day
In one study, people with painful osteoarthritis of the knee who received an oral enzyme-flavonoid preparation saw more improvement in pain and joint function than those who took a nonsteroidal anti-inflammatory (NSAID).

In a double-blind study, a group of people with painful osteoarthritis of the knee received an oral -flavonoid preparation or a nonsteroidal anti-inflammatory (NSAID) for six weeks. While both treatments relieved pain and improved joint function, the enzyme-flavonoid product appeared to be slightly more effective than the NSAID. No serious side effects were seen. The enzyme-flavonoid product used in this study was Phlogenzym (Mucos Pharma, Geretsried, Germany). Each enteric-coated tablet contained 90 mg of bromelain, 48 mg of trypsin, and 100 mg of rutosid (a derivative of the flavonoid rutin); one tablet was given three times a day.

Tendinitis
Several tablets per day of proteolytic enzymes
Supplementing with digestive enzymes may reduce the severity of symptoms and speed healing.

Alternative healthcare practitioners frequently recommend for various minor injuries. Research demonstrates that these enzymes are well absorbed when taken by mouth, and preliminary and double-blind trials have shown their effectiveness for reducing pain and swelling associated with various injuries and for speeding up the healing process. Unfortunately, many of these studies did not specifically identify the patients’ injury, so it is unclear whether the positive results included improvements in tendinitis.

Acne Rosacea
Refer to label instructions
Digestive enzymes have been reported anecdotally to improve rosacea symptoms.

Some people with rosacea have been reported to produce inadequate stomach acid. In a preliminary trial, supplemental hydrochloric acid, along with vitamin B complex, improved some cases of rosacea in people with low stomach-acid production. Similarly, improvement in rosacea has been reported anecdotally after supplementation with , and a controlled study found that rosacea patients produced less pancreatic lipase than healthy people. Controlled trials are needed to evaluate the effects of hydrochloric acid and digestive enzyme supplements in rosacea. Hydrochloric acid supplements should not be taken without the supervision of a healthcare practitioner.

Allergies and Sensitivities and Food Allergies
Refer to label instructions
Proteolytic enzymes may theoretically reduce allergy symptoms by breaking down undigested protein to sizes that are too small to cause allergic reactions.

According to one theory, allergies are triggered by partially undigested protein. Proteolytic may reduce allergy symptoms by further breaking down undigested protein to sizes that are too small to cause allergic reactions. Preliminary human evidence supports this theory.Hydrochloric acid secreted by the stomach also helps the digestion of protein, and preliminary research suggests that some people with allergies may not produce adequate amounts of stomach acid. However, no controlled trials have investigated the use of enzyme supplements to improve digestion as a treatment for food allergies.

Chronic Candidiasis
Refer to label instructions
Digestive enzymes inhibit the overgrowth of candida and prevent it from becoming established in the small intestine.

It is unknown if taking or betaine HCl (hydrochloric acid) tablets is beneficial for chronic candidiasis. Nonetheless, some doctors recommend improving digestive secretions with these agents. Hydrochloric-acid secretion from the stomach, pancreatic enzymes, and bile all inhibit the overgrowth of Candida and prevent its penetration into the absorptive surfaces of the small intestine. Decreased secretion of any of these important digestive components can lead to overgrowth of Candida in the gastrointestinal tract. Consult a physician for more information.

1 Star
Crohn’s Disease
Refer to label instructions
Supplementing with enzymes might improve the nutrient malabsorption that is often associated with Crohn’s disease.

People with Crohn’s disease may be deficient in , including lipase. In theory, supplementing with enzymes might improve the nutrient malabsorption that is often associated with Crohn’s disease. However, people with Crohn’s disease considering supplementation with enzymes should consult a doctor.

Low Back Pain
Refer to label instructions
Several trials have reported reduced pain and swelling, and/or faster healing in people with a variety of conditions who use papain.

Several preliminary trials have reported reduced pain and swelling, and/or faster healing in people with a variety of conditions using either bromelain, papain from papaya, or a combination of trypsin and chymotrypsin. Double-blind trials have reported faster recovery from athletic injuries, including sprains and strains, and earlier return to activity using eight tablets daily of trypsin/chymotrypsin, four to eight tablets daily of papain, eight tablets of bromelain (single-blind only), or a combination of these enzymes. However, one double-blind trial using eight tablets per day of trypsin/chymotrypsin to treat sprained ankles found no significant effect on swelling, bruising, or overall function.
