Digestive enzymes

Additional Reading

Carbohydrates are broken down by enzymes like amylase (found in saliva and pancreatic juices) into simpler sugars. Proteins are digested by enzymes such as pepsin (in the stomach) and trypsin and chymotrypsin (from the pancreas) into amino acids. Fats, on the other hand, are broken down by lipase, primarily produced in the pancreas, into fatty acids and glycerol.

However, there are situations where the body might not produce enough of these enzymes or where supplemental enzymes might be beneficial. For instance, some people have conditions or diseases that reduce their body's ability to produce or secrete these enzymes, leading to digestive problems. Conditions like chronic pancreatitis, cystic fibrosis, or surgical removal of parts of the stomach or pancreas can lead to enzyme deficiencies. Moreover, as people age, the production of certain enzymes may decrease, potentially leading to digestive discomfort after eating certain foods.

Digestive enzyme supplements are used for various reasons. For those with diagnosed enzyme deficiencies, these supplements can be essential for the proper digestion of food and nutrient absorption. Yet, for others, they might be taken to address symptoms of indigestion, such as bloating, gas, or feelings of fullness after eating. There are some that might also take them to aid in the digestion of specific foods they find difficult to digest, such as lactose in dairy products. Lactase supplements, for example, are commonly taken by those with lactose intolerance to help digest lactose-containing foods without experiencing gastrointestinal discomfort.

It's also worth noting that while many people find relief from digestive discomfort by using enzyme supplements, the efficacy of these supplements can vary. Not everyone will benefit from them, and it's essential to use them under the guidance of a healthcare professional, especially for those with chronic conditions or those taking other medications. Over-reliance without proper medical advice can lead to imbalances or mask underlying health issues.

The History of Digestive Enzymes

One of the earliest figures in this history was Santorio Santorio, an Italian Renaissance physiologist and physician. Santorio was deeply intrigued by the question of why the food and drink he consumed seemed to weigh more than his subsequent excretions.

To investigate this, he designed a unique weighing chair suspended from a scale, where he meticulously weighed himself, his food, urine, and feces over 30 years. This led to his theory of "insensible perspiration," suggesting that some substance was lost through the skin or mouth.

While Santorio did not fully understand the biochemical processes involved, he was on the right track in realizing that weight loss was indeed a result of water loss through breath and skin, a by-product of the body’s breakdown of food​​.

The term "metabolism," which is closely related to the function of digestive enzymes, was coined much later, in 1839 by German physiologist Theodor Schwann. Schwann was also one of the first to recognize that all living things are composed of cells.

The understanding of metabolism includes two types: catabolism, the breaking down of complex molecules, and anabolism, the building up of molecules. When we consume food, digestive enzymes play a crucial role in breaking down fats, carbohydrates, and proteins into their building blocks, which are then used to synthesize ATP, the basic form of fuel for the body​​.

The concept of enzymes, the catalysts of biochemical reactions, was not well understood until the late 17th and early 18th centuries. It was French chemist Anselme Payen who first discovered an enzyme, diastase, in 1833. This discovery was a significant milestone in enzymology.

However, it wasn't until the late 19th and early 20th centuries that the biochemical identity of enzymes was clarified. Scientists like Eduard Buchner demonstrated that enzymes could facilitate chemical reactions outside of living cells, leading to his Nobel Prize-winning work on cell-free fermentation. By the 20th century, the crystallization and detailed study of enzymes like urease and catalase further cemented the understanding that enzymes are indeed proteins capable of catalysis​​. This journey from the Renaissance to modern biochemistry reveals the complexity and depth of our understanding of digestion and the crucial role of enzymes. It underscores how incremental scientific advancements over centuries have built our current knowledge of human biology and metabolism.

Ingredients of Digestive Enzymes

Digestive enzyme supplements typically contain a range of enzymes to aid in the digestion of various food components. The main types of enzymes included are:

• Amylase - Breaks down complex carbohydrates.
• Lipase - Aids in the digestion of fats.
• Protease - Breaks down proteins into amino acids.
• Lactase - Specifically breaks down lactose, the sugar in milk.
Sucrase - Helps digest sucrose, a type of sugar.

These enzymes are crucial for proper digestion, as they help break down food into smaller, absorbable components. The pancreas is the primary source of these enzymes in the body. In cases where the body doesn't produce enough enzymes or doesn't release them effectively, digestive enzyme supplements can be beneficial. Conditions like exocrine pancreatic insufficiency (EPI) and lactose intolerance are examples where these supplements might be used​.

Who should take Digestive Enzymes

Digestive enzymes are particularly beneficial for individuals who have conditions affecting their natural enzyme production or release. People with conditions such as Exocrine Pancreatic Insufficiency (EPI), where the pancreas doesn’t produce enough digestive enzymes, and lactose intolerance, characterized by a deficiency in lactase enzyme, may find these supplements helpful. Additionally, those with find these supplements helpful. Additionally, those with congenital enzyme deficiencies, chronic pancreatitis, cystic fibrosis, or gastrointestinal surgeries that impact enzyme production may also benefit from enzyme supplements.

What Digestive Enzymes are NOT intended for

• Individuals with Allergies People who are allergic to specific enzymes or ingredients in the enzyme supplements should avoid them.
• People with Chronic Pancreatitis While some individuals with chronic pancreatitis may benefit from enzyme supplements, others may experience worsening symptoms.
• Those with Liver Disease People with liver disease may need to avoid certain enzymes, as their condition could be exacerbated.
• Individuals with Gastric or Duodenal Ulcers Digestive enzymes may irritate the lining of the stomach or duodenum, worsening ulcers.
• People on Certain Medications Those taking certain medications, such as anticoagulants or anti-inflammatory drugs, should consult a doctor before using digestive enzymes.
