Amylase

A starch-digesting enzyme, almost always sold inside a multi-enzyme blend. Blends show modest symptom benefits in functional dyspepsia; amylase on its own has essentially no evidence in people with a working pancreas.

What the science says

  • Multi-enzyme blends in functional dyspepsia Moderate evidence

    A randomized, double-blind, placebo-controlled trial in 120 adults found a fungal multi-enzyme blend improved dyspepsia quality-of-life, pain and sleep scores over two months, and an earlier placebo-controlled trial of a multienzyme complex reported similar symptom benefits.

  • Digestive effects are measurable but small Limited evidence

    A randomized, double-blind crossover trial in 30 middle-aged and older adults found a six-enzyme mixture including amylase shifted postprandial glucose and fatty acid curves and slightly sped leucine appearance, but did not change overall plasma amino acid responses to a mixed meal.

  • Amylase alone is untested Limited evidence

    No trial isolates amylase. Healthy people secrete salivary and pancreatic amylase well in excess of need, so a supplemental dose has no obvious deficit to correct.

Dosage & safety

Studied doseLabel doses inside blends are typically 5,000–20,000 DU of amylase per capsule, taken with meals; the dyspepsia trial used 400 mg/day of blend.
SafetyWell tolerated; occasional nausea or cramping. Fungal enzymes derived from Aspergillus oryzae can provoke reactions in people with mould allergy. These products do not treat pancreatic insufficiency, which requires prescription pancrelipase. Added amylase raises the glycaemic response to starchy meals, which is worth noting in diabetes.

How to take it

TimingWith the first bites of a meal — taken afterwards it largely misses the food.
With food?Always with food; there is nothing for it to act on otherwise.
Worth knowingIf fat or protein is what bothers you rather than starch, amylase is the wrong enzyme — and none of these treat pancreatic insufficiency.

Interactions

With medications

  • acarbose and other alpha-glucosidase inhibitors

    These drugs work by slowing starch digestion; added amylase works directly against them. do not combine

  • insulin and other diabetes medication

    Faster starch breakdown raises the glycaemic spike from a starchy meal. watch your post-meal glucose when starting

Well-established interactions only — this is not a complete list. Always tell your doctor and pharmacist what you take.

Frequently asked questions

Do amylase enzyme supplements help digestion?

Amylase on its own has essentially no evidence in people with a working pancreas, which already secretes amylase well in excess of need (limited). Multi-enzyme blends containing amylase have moderate evidence for modest symptom benefits in functional dyspepsia.

When should I take amylase?

Take amylase with the first bites of a meal; taken afterwards it largely misses the food. Label doses inside blends are typically 5,000–20,000 DU per capsule.

Does amylase affect blood sugar?

Added amylase speeds starch breakdown and raises the glycaemic response to starchy meals, so watch post-meal glucose if you use insulin or other diabetes medication. Do not combine amylase with acarbose, which works by slowing starch digestion.

Can amylase treat pancreatic insufficiency?

No, over-the-counter amylase and digestive enzyme blends do not treat pancreatic insufficiency, which requires prescription pancrelipase. Aspergillus-derived amylase can also provoke reactions in people with mould allergy.
