Standard Process Gastrex Journeys Holistic Life

Key Benefits of Gastrex

Gastrex combines vitamins, minerals, and a unique blend of whole food ingredients. Together, these support healthy digestion and help settle the stomach.

Foundational Nutritional Support

Each dose includes helpful nutrients such as:

  • Vitamin C: Supports immune function and tissue repair.

  • Niacin: Helps with digestion, energy production, and skin health.

  • Vitamin B6: Supports brain function and energy conversion from food.

  • Sodium: Helps regulate fluid balance and nerve function.

These nutrients work behind the scenes to support overall wellness.

  • Okra: Gentle fiber that helps soothe and support the gut.

  • Spanish moss: Traditionally used to calm irritation.

  • Anise: Helps reduce gas and bloating.

  • Bovine liver: Provides natural B vitamins and iron.

  • Porcine stomach and porcine duodenum: Natural sources of digestive enzymes.

Together, these ingredients support the stomach lining, digestion, and nutrient absorption.
