Activated B-Complex by Swanson Health Products provides all eight essential B-vitamins in their most bioactive, co-enzyme forms, ready for direct use by the body.
This advanced complex helps maintain normal energy metabolism, supports the nervous system, contributes to mental performance, and reduces tiredness and fatigue.
Unlike standard B-vitamins that require conversion in the liver, Swanson’s activated forms—such as methylcobalamin (B-12), pyridoxal-5-phosphate (B-6), and riboflavin-5-phosphate (B-2)—ensure optimal absorption and utilisation.
Bioactive Forms for Immediate Use
Contains fully activated coenzyme forms that bypass hepatic conversion, ensuring faster metabolic integration.
Energy & Fatigue Support
Contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue (EFSA-approved claim).
Nervous System & Cognitive Function
B-vitamins (B-1, B-2, B-6, B-12, niacin, biotin) contribute to normal neurological and psychological function.
Homocysteine & Heart Health
Vitamins B-6, B-12 and folate contribute to normal homocysteine metabolism, supporting cardiovascular wellbeing.
Stress & Mood Balance
Helps maintain normal mental performance under demanding conditions, ideal for students and professionals.
