Grapefruit Seed Extract, GSE

What Is Grapefruit Seed Extract?

Grapefruit seed extract powder is a natural antioxidant with antibacterial and antifungal properties. Although, as the name suggests, it comes only from the seeds of citrus paradisi, as manufacturers, we also extract it from the membranes and pulp.

Grapefruit is rich in phytochemicals that fight fungi, bacteria, and viruses. These include ascorbic acid powder (vitamin C), citric acid powder, flavonoids, limonoids, sterols, tocopherols (vitamin E), and other minerals.
