Product Information

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.

"Awful side effect"
By Anonymous , 03 Jun 2019
I thought this product would help all-round energy levels and well-being. All it did was scare me by giving me fluorescent yellow urine. No warnings given on packaging.
Recommend to a friend: No
Thank you for taking the time to leave a review.

The change in urine colour is completely normal, and is a result of your body excreting any excess vitamin B2, as this is water soluble. This is not a cause for concern and simply an indication that the body is absorbing the nutrients it needs. I have contacted you directly to discuss this further.

"I feel great! At last a solution to help pms."
By Anonymous , 18 May 2019
After many years of suffering from severe pms I’ve found a supplement that works. I take this b complex alongside flaxseed oil, magnesium citrate, ferrous citrate. I’ve improved greatly. Before this I was feeling sick, dizzy, had migraines and period pain, my temper was dreadful. I’d say I’m 90% cured. An excellent service from Nature’s Best consultants and delivery!
