Digestive Enzymes 101: Which One Do You Need?

Reviewed by Dr. Kristi Hughes, Head of Nutrition Strategy

If you've ever felt uncomfortably full, bloated, or gassy after a meal — especially a rich or unfamiliar one — a digestive enzyme supplement may be worth understanding. Here's a plain-language breakdown of what these enzymes actually do.

What Digestive Enzymes Do

Your body naturally produces enzymes in the mouth, stomach, and pancreas to break down food into absorbable nutrients. Enzyme supplements provide additional support for this process, which can be useful after large meals, with age-related enzyme decline, or for people who experience occasional digestive discomfort.

The Main Types of Digestive Enzymes

• Amylase — breaks down carbohydrates and starches.
• Protease — breaks down proteins into amino acids.
• Lipase — breaks down fats.
• Lactase — breaks down lactose, useful for those with dairy sensitivity.
• Cellulase — breaks down fiber from vegetables and grains that the human body doesn't naturally produce enzymes for.

Choosing the Right Formula

A broad-spectrum enzyme blend (covering carbs, protein, and fat) is a reasonable starting point for general digestive support after meals. If you have a specific sensitivity — like dairy or gluten — look for a formula that emphasizes the relevant enzyme (Lactase or DPP-IV, for example).

When to Take Them

Most digestive enzyme products are designed to be taken at the start of a meal, so the enzymes are active as food enters the digestive tract. Always check the label of your specific product, since formulations vary.

A Note on Quality

Look for enzyme products that state their potency in standardized units (like HUT, DU, or FCC units) rather than only milligrams — this tells you the actual activity level, not just the weight of the ingredient.

Not medical advice. If digestive discomfort is frequent or severe, consult a healthcare provider to rule out underlying conditions.
