Why We Love It
  • Supports energy and metabolism.
  • Perfect blend of B vitamins.
  • Superior bioavailability and absorption.
Main Highlights
  • REASSURINGLY EXPENSIVE - VitaBright Super B Complex is not for cost-cutters. If you’re after quality and results, read on. Our doses are much higher than cheaper options, and carefully balanced by our clinical nutritionist for efficient nutritional support. There are eleven B vitamins and, unlike low-budget alternatives, our formula includes all of them. It also includes vitamin C because of its many complementary functions with the B vitamins.
  • BODY-READY METHYLATED B COMPLEX VITAMINS - We manufacture using more pricey ingredients. Our vitamins are methylated and in their active, body-ready forms so they don’t need your own enzymes to modify them before they can get to work. The active formula includes active vitamin B3 (niacinamide), active vitamin B6 (high strength P-5-P), 5-MTHF methyl folate and B12 supplements as methylcobalamin & adenosylcobalamin.
  • HOW TO USE - Take 2 tablets a day. The bottle lasts 2 months. Our tablets are slimline and easy to swallow, coated with vegetable fibre (hypromellose) so they glide down easily. This is the only way to disguise the bitter taste of B vitamins - when they’re at the strong doses in our supplement. We don’t make liquid, spray or drops, which have weaker doses to make the taste acceptable.
  • B VITAMIN COMPLEX PROVEN HEALTH BENEFITS (CLAIMS AUTHORISED BY EFSA) - The B vitamins contribute to energy-yielding metabolism and the reduction of tiredness and fatigue, functioning of the nervous system, psychological function and mental performance, the immune system, hormonal activity, macronutrient metabolism and cardiovascular health (homocysteine metabolism, formation of red blood cells and heart function).
  • BEST OF BRITISH QUALITY - VitaBright vitamin B complex tablets are made in Britain, in BRC accredited grade AA manufacturing facilities operating to GMP standards. We use only the finest ingredients, double seal all bottles, and test for heavy metals to ensure there is no compromise on quality or safety. VitaBright Vitamin B Complex with folate delivers potent, premium B vitamins for women and men who want above average quality.
