Everything you need to know:

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

B vitamins work synergistically together as a team. Taking individual B vitamins can create imbalances, while a complete B-complex ensures all eight essential B vitamins work together harmoniously.

By taking our B-complex supplement, you support energy-yielding metabolism, nervous system function, and normal skin, vision and red blood cells, and so much more.

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

Why is 50 mg considered the optimal amount? +

The 50 mg B-complex provides 100% recommended daily amount of essential B vitamins. This strength ensures you’re getting a meaningful dose that can make a difference: for example reduced fatigue and tiredness and normalized psychological function.

Can B vitamins help with my energy levels? +

Unlike stimulants that provide temporary energy spikes, B vitamins support your body’s natural energy production at the cellular level.

Is this B-complex good 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 that it works

7 B vitamins in 1 formula

50 mg of essential B vitamins for energy, nervous system support, and psychological function

(B1, B2, B6, B12, folic acid, pantothenic acid, niacin)

  • Why should vegans and vegetarians choose this B-complex?

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 turn to a complete B-complex. Ours combines seven essential B vitamins in one formula that fits perfectly into a plant-based lifestyle.

  • Are you dealing with persistent fatigue despite getting enough sleep?

B-complex contributes to normal energy-yielding metabolism and the reduction of tiredness and fatigue. This complete complex ensures your body has all the B vitamins it needs to feel less fatigued.

  • Do you want to support your nervous system and psychological function?

B-complex contributes to normal functioning of the nervous system and normal psychological function. Vitamin B6 contributes to regulation of hormonal activity.

Choose our B-Complex

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

  • Complete 50 mg formula

Our B-complex provides 100% NRV of 7 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 7 B vitamins (B1, B2, B6, B12, folic acid, pantothenic acid, niacin) that work together.

  • Perfect for busy, demanding lifestyles

Ideal for students, athletes, or anyone with high energy demands. B vitamins contribute to the reduction of tiredness and fatigue, contribute to normal functioning of the nervous system and to normal psychological function.

  • Perfect for vegans and vegetarians:

All seven B vitamins in one easy-to-mix plant-based formula, including B12.

  • Delicious natural orange flavour

Our B-complex features natural orange flavour (5%) plus real orange powder (0.1%), creating a refreshing citrus drink that makes daily B vitamin intake enjoyable.

Why powder form matters

  • Better absorption
    Liquid supplements can be absorbed more readily than compressed tablets, meaning your body can utilize the B vitamins effectively.
  • Dosage flexibility
    Start with half a serving if needed, or adjust based on individual requirements.
  • Integrate it easily into your life
    Add to your morning smoothie, post-workout drink, or evening routine. Make B-complex supplementation work for your lifestyle.
  • Easy to mix and dissolve
    We’ve all bought fizzy tablets that clump, stick to the glass, or leave gritty residue. Our formula dissolves instantly and completely, making your daily B-complex intake pleasant.
  • Consistency is key
    The easier it is to take, the more likely you are to take it consistently. And with supplements, consistency is everything.

Start taking your B-complex today

If you start with B-complex TODAY:

  • You get complete B-complex coverage in optimal ratios
  • You contribute to the reduction of tiredness and fatigue
  • You support normal functioning of the nervous system
  • You support normal red blood cell formation
  • You contribute to regulation of hormonal activity

If you start taking B-complex later:

  • You continue to rely on potentially inadequate B vitamin intake
  • You delay extra nervous and immune system support
  • You delay optimizing your psychological function and hormonal activity
