The Active Ingredient Is: Onion (Allium cepa) bulb extract

Onion bulb extract is a plant-based ingredient used in herbal supplements for everyday health support.

This form comes from the Allium cepa bulb and is described in product info as gluten-free and non-GMO, with the extract supplied in capsule form.

What Does Onion Bulb Extract Do?

Onion bulb extract supports antioxidants and helps deliver natural compounds like flavonoids that contribute to overall wellness.

This mechanism lines up with what people generally understand about onion components as antioxidant sources that may help protect cells from oxidative stress, as recognised in EFSA and NHS-focused guidance on nutrient function and antioxidant activity.
