Everything you need to know:

Why is magnesium so important for me? +

Magnesium is involved in over 300 enzymatic reactions in your body, making it one of the most important minerals for overall wellbeing. Despite its importance, many people don’t get enough magnesium from their diet alone.

Our formula offers you 375 mg magnesium citrate per serving (100% NRV), meaning you’re covering your daily needs for this important mineral.

Can magnesium help me if I’m often tired and feel fatigue? +

If you’re experiencing ongoing fatigue, it could be related to inadequate magnesium intake. Magnesium contributes to the reduction of tiredness and fatigue, while also supporting normal energy-yielding metabolism.

Why should I take magnesium if I’m active and I work out? +

Magnesium is one of those minerals that works quietly in the background, but its impact on both your psychological function and exercise performance is huge.

Beyond physical benefits, magnesium contributes to normal psychological function and to reduction of tiredness and fatigue. Magnesium contributes to normal protein synthesis and to normal muscle function.

Magnesium also contributes to electrolyte balance, so it’s especially essential for physically active people.

Why should I choose this specific formula? +

Our formula offers you 375 mg magnesium citrate per serving, meaning you’re covering your daily needs for this important mineral.

The powder form allows for better absorption and faster utilization by your body. Plus, it’s more convenient, just mix with water and drink.

Our customers also confirm that it works

Experiencing fatigue? Suspecting you’re lacking magnesium?

Choose 375 mg of magnesium citrate for muscles, psychological function and against fatigue

  • Do you often feel tired throughout the day?

Magnesium contributes to the reduction of tiredness and fatigue, while supporting normal energy-yielding metabolism. With 375 mg per serving, you’re covering your daily magnesium needs.

  • Do you want to support electrolyte balance?

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

  • Are you trying to build muscles?

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

  • Do you feel stressed or mentally overwhelmed?

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

Choose our magnesium

You already know magnesium matters. Here’s why our magnesium makes the difference:

High-strength formula

Unless your diet is excellent, you’re likely not covering your daily magnesium needs with food alone. With 375 mg of magnesium per serving in this formula, you get your daily requirement.

Magnesium citrate – one of the most absorbable types of magnesium

Magnesium citrate is a type of magnesium that has been combined with citric acid. As the name suggests, this is the acid that gives citrus fruits their tangy taste. Magnesium citrate is a popular choice, because it’s known to be more easily absorbed than some other types.*

With added inulin

This formula features inulin, a source of dietary fibre, containing 90 g per 100g.

Built for busy and active lifestyles

Perfect for athletes, gym enthusiasts, or anyone with a busy lifestyle who needs muscle support. Magnesium contributes to normal muscle function and electrolyte balance and contributes to normal protein synthesis.

Delicious citrus flavour

Our magnesium has a refreshing, natural orange flavour and lemon flavour. You won’t find any added sugar in our formula.

*Walker AF, Marakis G, Christie S, Byng M. Mg citrate found more bioavailable than other Mg preparations in a randomised, double-blind study. Magnes Res. 2003 Sep 16(3): 183-91. https://pubmed.ncbi.nlm.nih.gov/14596323/

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 routine 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 support the reduction of tiredness and fatigue¹
  • You contribute to normal muscle function¹
  • You support normal energy-yielding metabolism¹
  • You contribute to normal psychological function¹
  • 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
