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.

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.

If you start taking magnesium later:
