Everything you need to know:

Why should I choose a complete B-complex instead of individual B vitamins?

B vitamins work synergistically as a team. Taking a complete B-complex ensures that all eight essential B vitamins work together in harmony.

Individual B vitamins are most effective when taken together as part of a complete B-complex.

Choose our B-complex to cover 100% of your daily needs.

Can B-complex vitamins reduce tiredness and boost energy?

Yes! Vitamins B2, B3, B5, B6, and B12 contribute to the reduction of tiredness and fatigue.

Is this B-complex suitable for vegans and vegetarians?

Absolutely. Our formula is 100% vegan and vegetarian. If you follow a plant-based lifestyle, you know some B vitamins are harder to get from food alone — especially B12. This powder gives you all the essentials in one scoop, so you can cover all your daily needs.

Our customers also confirm it works

7 B vitamins in 1 formula

Formulated to provide all essential B vitamins in a single formula

Choose our B-Complex

You know B vitamins are essential. Here’s why our B-complex formula delivers superior results:

  • Complete formula

Our B-complex provides 100% NRV of 8 essential B vitamins in one convenient serving. This means you are covering your daily needs for B vitamins.

  • Balanced B vitamin ratios

Rather than random amounts, our formula provides balanced ratios of 8 B vitamins (B1, B2, B6, B12, folic acid, pantothenic acid, niacin) that work together.

  • Support your nervous system and psychological function

Vitamins B1, B2, B5, B6, and B12 contribute to the normal functioning of the nervous system and Vitamin B6 also contributes to the regulation of hormonal activity.

  • Perfect for busy, demanding lifestyles

This is ideal for students, athletes, and anyone with high energy demands, because vitamins B2, B3, B5, B6, and B12 help reduce tiredness and fatigue, while B1, B6, B9, and B12 support normal psychological function – helping you stay energised and focused throughout the day.

  • Perfect for vegans and vegetarians

If you don’t eat animal products, it can be tricky to get enough of certain B vitamins. That’s why so many vegans and vegetarians choose a complete B-complex. Ours combines eight essential B vitamins in one formula that fits perfectly with a plant-based lifestyle.

  • Delicious natural orange flavour

Our B-complex features natural orange flavour (5%), creating a refreshing citrus drink that makes daily B vitamin intake enjoyable.

  • You will maintain normal psychological function with vitamins B1, B6, B9, and B12
