About the Ingredients

Turmeric: Curcuma xanthorrhiza is a unique form of turmeric where research has shown that when fed to horses it may suppress the formation of stomach ulcers.1

PowerStance (Powdered coconut oil): may assist in the absorption of the Curcuma xanthorrhiza, while the lauric acid may provide anti-bacterial properties.2

Seaweed Derived Calcium: is harvested from red algae (Lithothamnion). Lithothamnion has a honeycomb structure that provides a large surface area of (>10m2) per gram and a slow release of bio-available minerals, calcium, magnesium and silicon. It has a longer buffering action than limestone or sodium bicarbonate. Research shows this had a significant buffering action for 4-6 hours under simulated in-vitro stomach digestion conditions and also simulated in-vitro hindgut fermentation activities.3

Actigen: is a strain of yeast containing Mannan Oligosaccharides (MOS). MOS are considered a prebiotic and are thought to promote the growth of healthy gut bacteria. They are thought to reduce the number of pathogenic bacteria in the hindgut. They may also boost the immune function in the digestive tract.

Yea-SaccTS: Yea-sacc is a probiotic (live microorganism) that works symbiotically with Actigen (a prebiotic) and helps promote beneficial bacteria and fiber digestion in the hindgut as well as help to stabilise the hindgut pH.

Sodium Alginate: may assist in maintaining the integrity of the mucus membrane within the digestive tract.
