Enzymes: What They Do and Why You Should Care

Enzymes are the body's chemical workers. They speed up reactions that would otherwise take too long to keep you alive. Every bite you eat, every cell that divides, and most drugs you take involve enzymes. If you know the basics, you can make smarter choices about medicines, supplements, and tests.

How enzymes work is simple. An enzyme has an active site that fits a molecule called a substrate. When they bind, the enzyme changes the substrate into products. Temperature, pH, and some chemicals change how well enzymes work. Heat can break them; acid can slow them. The body keeps enzymes in a narrow range so metabolism runs smoothly.

Medications often target enzymes. Some drugs block enzymes to treat disease, while others rely on enzymes to become active. For example, Xenical (Orlistat) blocks pancreatic lipase so your body absorbs less fat — that’s why it must be taken with meals that contain fat. Methotrexate blocks dihydrofolate reductase to slow rapidly dividing cells, which is useful for autoimmune disease and cancer but can cause side effects. Antibiotics like ciprofloxacin target bacterial enzymes such as DNA gyrase; that can cure infections but also bring rare risks. Knowing which enzyme a drug hits helps you predict effects and interactions.

Enzyme tests are common in medicine. Blood levels of ALT and AST tell doctors about liver stress. High enzyme levels after a new drug often trigger extra monitoring or dosage changes. Ischemia, where tissue gets too little blood, releases certain enzymes and can damage organs like the eye. If you see abnormal test results, ask what enzyme changed and why.

Digestive enzyme supplements are popular, but they’re not a cure-all. Enzyme pills can help if your pancreas produces too little enzyme or if you digest heavy meals poorly. Timing matters: take digestive enzymes with food so they mix with what you eat. Natural supplements such as lingonberry may support digestion and inflammation, but they work differently from enzymes and should not replace medical advice.

Practical tips to use right away:

- Read how a drug works. If it’s an enzyme blocker, learn when to take it and what labs to watch. - Take Orlistat with meals containing fat; miss the meal, skip the pill. - If a doctor orders liver enzymes, track trends, not single numbers. - Don’t mix enzyme supplements with prescription enzymes or fire up your own dosing plan. - Tell your doctor about herbs and supplements — some change enzyme activity and drug levels.
