Guava leaf extract is made from guava leaves. It delivers flavonoids, tannins, and quercetin. While the fruit is a snack, the leaf extract is used for digestion and metabolism.
People reach for it to calm occasional bloating or diarrhea and help maintain balanced blood sugar alongside a healthy diet. It comes in capsule or liquid extract form.
Take it with a meal to boost absorption and reduce stomach upset. Some people take it before meals when their goal is digestive support.
Mild digestive discomfort is a possible side effect. Talk to a healthcare professional before starting, especially if you have a health condition or take other medications.
