Everything you need to know:

What makes our 400 mg dosage more effective? +

Many people have higher magnesium needs due to stress, exercise, or dietary factors. Most magnesium supplements provide basic maintenance doses. Our 400 mg (106.6% NRV) delivers levels that can make a real impact on your energy, muscle function, and stress resilience.

Magnesium contributes to the reduction of tiredness and fatigue, normal muscle function, and normal psychological function. Higher doses mean better results.

Is magnesium citrate better than other magnesium forms? +

Magnesium citrate offers excellent bioavailability and is gentle on the stomach. Combined with our powder format for rapid absorption, this ensures your body can effectively utilize the full 400 mg dose for maximum benefit.

Why does this product save me money? +

The 200 g economy pack provides more servings per purchase, reducing the per-dose cost. You get more benefits from using magnesium regularly, so this format supports both your health goals and budget.

Want more magnesium for your money?

200 g pack delivers premium magnesium with delicious ice tea flavour

Stop feeling tired throughout the day

Magnesium contributes to the reduction of tiredness and fatigue, while supporting normal energy-yielding metabolism. With 400 mg per serving, you’re covering your daily magnesium needs.

Support electrolyte balance

Magnesium is the one of the most popular minerals in sports supplementation. Magnesium contributes to electrolyte balance, to the reduction of tiredness and fatigue and to normal energy-yielding metabolism.

Build muscle

Whether you’re an athlete or simply dealing with everyday muscle tension, magnesium contributes to normal muscle function. Magnesium also contributes to normal protein synthesis.

Feel less stressed and mentally overwhelmed

Magnesium contributes to normal psychological function and normal functioning of the nervous system and to reduction of tiredness.

Maximum strength formula with magnesium citrate

Economy pack – Get more for your money!

We believe in providing the best value for your hard-earned money.

At 400 mg per serving with 106.6% NRV, you get more magnesium per euro than standard supplements.

With our economy pack, you can enjoy the immense benefits of magnesium while saving up to 20%!

Don’t settle for less – maintain consistent supplementation without constantly reordering.

Why powder form is better

  • Better absorption
    Liquid supplements can be absorbed more readily than compressed tablets, meaning your body can utilize the magnesium more effectively.
  • Dosage flexibility
    Start with half a serving if needed, or adjust based on your individual requirements.
  • Integrate it easily into your life
    Add to your morning smoothie, in your post-workout drink, or before sleep. Make supplementation work for your lifestyle.
  • Easy to mix and dissolve
    We’ve all bought fizzy tablets that stick to the glass, or leave gritty residue. Our formula dissolves instantly, making your daily magnesium 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 magnesium today

If you start taking magnesium TODAY:

  • You get 400 mg magnesium per serving
  • You support the reduction of tiredness and fatigue
  • You contribute to normal muscle function
  • You contribute to normal psychological function
  • You get high-strength magnesium in an easily absorbed form

If you start taking magnesium later:

  • You continue to experience the same level of fatigue
  • You miss out on optimal muscle function support
  • You delay supporting your psychological function
