B vitamins are crucial for energy production, brain function, and maintaining a healthy nervous system. Because B vitamins are water-soluble, they need to be replenished daily for optimal body function.
Nutri Advanced High Strength Vitamin B Complex delivers all eight essential B vitamins, alongside inositol, choline, and PABA, to help fight fatigue, boost cognitive function, and support overall wellbeing. Inositol and choline work synergistically with B vitamins to promote brain health, aid fat metabolism, and improve liver function. They also help maintain healthy cell membranes and support nerve signalling. PABA, a natural part of folic acid, complements the blend by enhancing the function of B vitamins.
Unlike standard formulas, this supplement uses bioavailable, active forms of B12, folate, B6, and riboflavin (B2), which are easier for the body to absorb and utilise. Perfect for those needing extra energy and nervous system support, it’s ideal for people experiencing fatigue, stress, or low B vitamin levels.
This formula provides B vitamins in their active, bioavailable forms, meaning they are ready for the body to use without needing conversion. Some individuals struggle to process standard B vitamins efficiently, which can reduce their effectiveness. By using active forms of folate, B12, B6, and B2, this supplement ensures optimal absorption and support for energy production, brain health, and nervous system function.
For over 40 years, Nutri Advanced has helped people take charge of their health with science-backed nutrition. Now part of Metagenics, a global leader in functional supplements, the brand remains committed to tackling health concerns at their root. Every formula is carefully crafted using the latest research and high-quality ingredients to support real, lasting wellness. With a strong focus on quality, sustainability, and expert guidance, Nutri Advanced continues to make better health more accessible—helping people feel their best every day.
