Everything about magnesium
What magnesium is, what forms exist, and how to use Magnesium Ultimate.
What is magnesium?
Magnesium is a mineral the body cannot produce itself; you get it from your diet and, if needed, from a supplement. For adults, the EU reference intake is 375 mg per day. Magnesium Ultimate provides 75.5 mg of elemental magnesium per capsule (20% of the reference intake) and 151 mg at the standard dose of two capsules per day (40%).
What magnesium does
Magnesium has authorised health claims in the EU. Magnesium contributes to a reduction of tiredness and fatigue. Magnesium contributes to normal muscle function. Magnesium contributes to normal psychological function. Magnesium contributes to the maintenance of normal bones. A varied, balanced diet and a healthy lifestyle are important; a food supplement does not replace these.
Bisglycinate and citrate: two forms
In a supplement, magnesium is always bound to another substance. For magnesium bisglycinate that is the amino acid glycine — two glycine molecules per magnesium ion, known as a chelate. For magnesium citrate that is citric acid. Magnesium Ultimate combines both: 615 mg magnesium bisglycinate (66.5 mg elemental magnesium) and 61.6 mg magnesium citrate (9 mg elemental magnesium) per capsule. Bisglycinate provides the largest part in this formula; citrate is a small addition.
Taurine
Taurine is an amino acid that occurs naturally in the body. Each Magnesium Ultimate capsule contains 92.4 mg taurine. There are no authorised health claims for taurine; we therefore only describe it factually.
How to use Magnesium Ultimate
Standard two capsules per day: one with breakfast and one with dinner, each with a glass of water. Do not take the capsule on an empty stomach — without fillers it is concentrated — and never more than one capsule at a time. A different dose only on the advice of your practitioner; do not exceed the recommended dose. Consult in advance in case of pregnancy, breastfeeding, kidney problems or medication use. Store the pouch dry and cool, closed and out of reach of young children.
Magnesium in your diet
Pumpkin seeds, almonds, cashew nuts, dark chocolate, wholegrain cereals, legumes and green leafy vegetables such as spinach naturally contain magnesium. A supplement is an addition to your diet, not a replacement: your plate first, then a capsule.
Quality from our own Dutch production
Magnesium Ultimate is made in the Netherlands in Natuurlijk.fit's own production facility, led by Michael Eekhof — lab experience since 2005. The production process is HACCP-assured and every batch is tested by an independent external laboratory. Because of the manual process, magnesium stearate and fillers are unnecessary: the vegan pullulan capsule contains only magnesium bisglycinate, magnesium citrate and taurine — without synthetic additives.
Packaged plastic-free
The 120 capsules come in a resealable, compostable kraft pouch — without plastic. Natuurlijk.fit is a plastic-free brand: all products are packaged this way. At two capsules per day, one pouch lasts two months.

green leaves.
