Where magnesium comes from
The best sources are seeds, nuts, pulses, wholegrains and green leafy vegetables. We go into detail in Magnesium-rich foods.
How to top up your intake
A supplement lets you secure a fixed amount every day. Our 2-capsule serving provides 200 mg of elemental magnesium, more than half the daily reference value:
Your daily serving against the reference value
Magnesium contributes to a reduction of tiredness and fatigue.
One capsule or two?
The label allows 1 to 2 capsules per day. We suggest the full serving of 2 capsules in the evening. If you prefer a gentler start, you can begin with 1.
Always read the elemental magnesium
When comparing products, look at the elemental magnesium per serving, not the weight of the compound. We explain it in Types of magnesium and elemental magnesium.
