UK's Strongest B Vitamin formula.

Product ID: 641
  • Only the highest quality B vitamins are used
  • Convenient one-a-day, coated tablets
  • The UK’s strongest and safe for short term use
  • Made in the UK to GMP pharmaceutical standards

This is the strongest B complex that is available in the UK, and we recommend this product is best taken for short periods of 2-3 months, during periods of convalescence, or as a quick boost to your B vitamin intake. After this period you should change to our B 50 Complex, our Multi B Complex, or choose one of our multis such as Multiguard® which has high B Vitamin levels.

If you are wondering if a B complex is what you need then this product will leave you in no doubt, (although the same could be said for our B50 Complex), which is why Nutritionists sometimes recommend a product of this strength.

As with all our products, these tablets are made in the UK to strict GMP pharmaceutical standards using the highest quality B vitamins available.

"Only taken once and caused indigestion. Huge pills!"
By , 28 Sep 2018
Just waiting to get a pill cutter so that I can manage these mega bombs. Also the plastic top was disfigured and very hard to open and close.

Thank you for taking the time to leave a review.

I am sorry to hear that the tablets are too large. For future reference we do offer a free sample service and can send a small quantity of most products so that you can assess the size.

These tablets are not known to cause indigestion, I can see that my colleague has spoken to you to resolve this issue.

We do advise that this product is used at the recommended dose for at least three months. Perhaps you would be kind enough to leave another review after this time.
