The Science
Complete Fibre. Complete Gut Support.
Dietary fibre is one of the most under-consumed nutrients in the modern diet, yet it's essential for digestive health, metabolic function, and immune performance. EFECTIV Fibre Powder delivers 5g per serving from three distinct sources: VITACEL® Oat Fibre (insoluble — adds bulk and promotes regularity), Inulin from Chicory Root (soluble prebiotic — feeds beneficial gut bacteria), and Psyllium Husk (soluble — forms a gel that slows digestion and supports satiety). Together, they provide complete fibre support in a single, unflavoured scoop.
Digestion
Soluble & insoluble fibre for complete digestive support
Microbiome
Prebiotic inulin feeds and grows beneficial gut bacteria
Satiety
Fibre slows gastric emptying to support appetite control
"Bioavailability is the key to effective sports nutrition."
