What Digestive Enzyme Helps With Garlic and Onion?

by Emily · Jul 23, 2026
The short version

Garlic and onion are high in fructans, so you want an enzyme formula that is built for fructans, not just lactase for dairy or alpha-galactosidase for beans. Après is designed to support digestion of garlic and onion fructans along with other common triggers like wheat, beans, dairy, and fiber.

Garlic and onion are the reason low-FODMAP eating feels impossible at restaurants. They are in sauces, dressings, marinades, soups, chips, spice blends, frozen meals, "natural flavors," and almost every delicious thing that starts with a pan and olive oil. If they bloat you, you need a strategy that works in real life, not only in your own kitchen.

Why garlic and onion are hard

Garlic and onion contain fructans, a type of fermentable carbohydrate. Fructans can reach the large intestine and get fermented by bacteria, which can lead to gas and bloating for some people. They are also potent: a little garlic or onion powder can season an entire sauce.

For the ingredient-label side, read ingredients that cause bloating. For restaurants, read what to order if you bloat.

What to look for in an enzyme

  • Fructan support: garlic and onion are fructan problems, not lactose problems.
  • Meal coverage: restaurant meals often include garlic, onion, wheat, dairy, beans, and fiber together.
  • Timing: take it with the meal, not after you are already bloated.
  • Food reality: the best formula is the one that matches what you actually eat.

Après supports digestion of garlic and onion fructans, plus other common meal triggers like wheat, dairy, beans, and fiber. That matters because garlic and onion rarely travel alone.
