Our B Complex is a high-strength formula with active forms of vitamin B6, folate and vitamin B12.

Key Benefits

  • All eight B-vitamins — contribute to normal energy-yielding metabolism, normal functioning of the nervous system, normal psychological function, and reduction of tiredness and fatigue.
  • Vitamin B12 as methylcobalamin — the active form the body can use directly, rather than cyanocobalamin, which first has to be converted.
  • Vitamin B6 as P5P (Pyridoxal-5-Phosphate) — the metabolically active form, at 8mg (571% NRV).
  • Folate as 5-MTHF (methyltetrahydrofolate) — folate contributes to normal psychological function and the reduction of tiredness and fatigue.
  • Choline and inositol added alongside — choline contributes to normal homocysteine metabolism and the maintenance of normal liver function.

Why Dr Marks?

We use the active forms of B6, folate and B12, at high-strength doses.

Take one capsule daily, ideally with food and a glass of water. B-vitamins are water-soluble with no established Tolerable Upper Intake Level for most forms used here; however, please check with your GP first if you take regular prescribed medication that can affect B-vitamin levels, or are on dialysis. Suitable for vegetarians and vegans. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

Directions: Take 1 capsule daily with water, ideally in the morning with food.

Format: Size 00 vegetable capsule (HPMC) — easy to swallow, suitable for vegetarians and vegans.

Free from: Artificial colours, sweeteners and preservatives; unnecessary fillers, binders or flow agents; gluten, dairy, soya and GMOs.

Storage: Store below 25°C in a cool, dry place, out of reach of children. Use within 3 months of opening.

Formulated by GPs in the UK and manufactured in GMP-certified, UK-based facilities.

Speak to your GP first if you are taking regular prescribed medication that can affect B-vitamin levels, or if you are on dialysis, as high-dose B-vitamins may interact with some treatments.
