The Active Ingredient Is: Fennel Seed (Foeniculum vulgare) Powder

Fennel seed is an herb used in traditional digestive support and is consumed here in its whole seed powder form for a full spectrum profile.

This powder is derived from fennel seeds (Foeniculum vulgare) and includes the seed’s natural compounds, which have been associated with digestive wellness and antioxidant activity.

What Does Fennel Seed Do?

Fennel seeds participate in relaxing gastrointestinal smooth muscle, which can help ease gas and bloating and support digestive comfort. They also play a role in promoting digestion and may contribute to hormonal balance through their phytochemical profile.

This combination relies on the seed’s bioactive compounds to support normal gut function and overall gastrointestinal wellbeing, aligning with traditional use and nutritional guidance.

This supplement is not intended to diagnose, treat, cure, or prevent any disease.
