In brief: the most direct alternative to Nutripure Magnesium Taurine B6 is SuperNutrition Magnesium Bisglycinate.
The difference lies in the raw material. Nutripure uses a buffered bisglycinate (80% bisglycinate, 20% magnesium oxide according to its own composition), while SuperNutrition uses pure unbuffered bisglycinate, without added oxide.
At an equivalent daily dose, SuperNutrition provides more truly chelated magnesium, for a cost per chelated milligram that is approximately 39% lower. Nutripure retains three clear advantages: taurine, two capsules per day instead of four, and compliance with the anti-doping standard. Here's how to decide.

Nutripure Magnesium in summary
Nutripure offers one of the best-selling magnesiums on the French market, with real documentary transparency (traceability sheets, downloadable labels and certificates). The formula is based on:
- 240 mg of elemental magnesium per day, or 64% of reference intakes, in 2 capsules;
- 300 mg of taurine and 1 mg of vitamin B6 (pyridoxine hydrochloride);
- a raw material described as "buffered magnesium bisglycinate (80% magnesium bisglycinate, 20% magnesium oxide)";
- a vegetable capsule made of pullulan, French manufacturing and compliance with the EN 17444 anti-doping standard;
- a rating of 4.7/5 from over 800 reviews, in 1, 3 and 6 month formats.
It's a serious formula, whose central argument is the magnesium-taurine-B6 synergy in few capsules. The question of an alternative arises especially for those who specifically seek pure bisglycinate, as we will detail.
Why look for an alternative to Nutripure magnesium?
Three legitimate reasons regularly come up:
- You are looking for bisglycinate, not a buffered form. Buffering with oxide is a common and declared practice in the industry, but if your initial intention is "bisglycinate", the formula does not quite meet this expectation.
- The quantity of chelated magnesium per euro. Part of the announced elemental magnesium comes from oxide, which changes the calculation of the value for money when considering chelated magnesium.
- The simplicity of the formula. Some profiles look for a single active ingredient, without taurine or other associated ingredients, to precisely control what they consume.
None of these points disqualify Nutripure. They explain why the comparison deserves to be made, especially for the specific demand for "bisglycinate."
The real issue: buffered bisglycinate or pure bisglycinate?
What "buffered" means
Magnesium bisglycinate is the so-called chelated form: magnesium is bound to two molecules of glycine, an amino acid. This form is recognized for its good digestive tolerance and assimilation.
Its industrial disadvantage is its low density: bisglycinate contains little magnesium per gram of raw material. To display a high dosage in a small number of capsules, part of the industry adds magnesium oxide, which is much denser. This is called buffered bisglycinate. The practice is legal and Nutripure clearly states it in its composition tab.
Why 80/20 doesn't mean 80/20
This is the point that few buyers calculate. The 80/20 ratio refers to the weight of the raw material, not the magnesium delivered. However, the two forms do not have the same elemental magnesium content: according to the table published by Nutripure itself, bisglycinate contains about 20%, oxide about 60%.
Out of 100 mg of buffered mixture: 80 mg of bisglycinate provide 16 mg of magnesium, 20 mg of oxide provide 12 mg. That's 28 mg in total, of which 43% comes from oxide. Applied to the announced 240 mg daily, this represents approximately 137 mg from bisglycinate and 103 mg from oxide.
This calculation deliberately uses the 20% content published by Nutripure, which is the most favorable to its formula. With the theoretical content of pure bisglycinate, closer to 14%, the oxide share would exceed 50%.
The SuperNutrition approach
SuperNutrition takes the opposite approach: 100% pure, unbuffered bisglycinate, without added oxide to inflate the advertised content. The trade-off is accepted and visible: it takes 4 capsules to reach 270 mg of elemental magnesium, whereas 2 capsules are enough with Nutripure. This is the price of chelate purity, and this is precisely what a buyer who types "magnesium bisglycinate" is looking for.
The formula also combines vitamin B6 in the form of bioactive P5P, directly usable by the body, whereas Nutripure uses pyridoxine hydrochloride, a classic form requiring prior conversion.
In summary: neither "good" nor "bad", but two different approaches. If your priority is pure chelate, SuperNutrition better matches that intention. If you want the full dosage in 2 capsules with taurine, Nutripure meets that need.
Price: the actual cost of a day's treatment
Comparing bottles is misleading, as dosages differ. It's necessary to consider the effective daily cost of treatment.
- SuperNutrition: €15.90 for 120 capsules, or 30 days at 4 capsules → €0.53/day.
- Nutripure 1-month format: €14.90 for 60 capsules at 2 capsules/day → €0.50/day.
- Nutripure 3-month format: €39.90 for 180 capsules → €0.44/day.
On this raw criterion, Nutripure is cheaper, especially for 3 or 6-month commitments. This should be stated clearly.
The ranking reverses as soon as the price is related to the amount of chelated magnesium actually provided. SuperNutrition delivers approximately 270 mg of chelated magnesium per day for €0.53, or €0.20 per 100 mg segment. Nutripure delivers approximately 137 mg for €0.44 in its most advantageous format, or €0.32 per 100 mg segment. The difference reaches approximately 39% in favor of SuperNutrition.
What Nutripure does better
Honestly, several points weigh in Nutripure's favor:
- Two capsules a day instead of four: a real gain in adherence for a long course of treatment.
- Taurine (300 mg), absent from the SuperNutrition formula: this is a real formulation addition, not a marketing argument.
- Compliance with the EN 17444 anti-doping standard, a decisive criterion for licensed athletes subject to control.
- The lowest daily price for 3 and 6-month formats.
- Considerable social proof (over 800 reviews on this product alone) and downloadable traceability documents.
The best product therefore depends on what you are looking for, not on an absolute ranking.
Which magnesium to choose according to your profile
- You are specifically looking for pure bisglycinate → SuperNutrition Magnesium Bisglycinate (100% chelated, unbuffered).

In all cases, magnesium is a long-term treatment: allow 2 to 4 weeks of regular intake to replenish your reserves. Regularity is more important than the displayed dosage. Also discover our comparison of the best forms of magnesium on the market.
What you should know about magnesium
Magnesium helps reduce fatigue, contributes to the normal functioning of the nervous system, normal psychological functions, normal muscle function, and the maintenance of electrolyte balance. Vitamin B6 also helps reduce fatigue and contributes to normal energy metabolism. (learn more about the benefits of magnesium)
These are the recognized contributions at the European level. A dietary supplement is not a substitute for a varied diet, nor for medical advice in case of persistent problems, pregnancy, breastfeeding, or ongoing treatment. In case of kidney failure, medical advice is essential before any supplementation.
Frequently asked questions
What is the best alternative to Nutripure Magnesium?
SuperNutrition Magnesium Bisglycinate is the most direct alternative for those seeking pure bisglycinate: 100% chelated, unbuffered, 270 mg of elemental magnesium per day, and vitamin B6 in bioactive P5P form. Nutripure remains relevant for its taurine, its intake in 2 capsules, and its anti-doping compliance.
Is Nutripure magnesium pure bisglycinate?
No. Its official composition indicates a buffered magnesium bisglycinate, consisting of 80% bisglycinate and 20% magnesium oxide. Given the respective elemental magnesium contents, approximately 43% of the magnesium provided comes from the oxide. For 100% bisglycinate, you need to look for an unbuffered formula.
What is buffered magnesium?
It is a bisglycinate to which magnesium oxide is added, a form much denser in elemental magnesium. This allows for a high dosage in few capsules. The practice is common and declared, but it reduces the proportion of truly chelated magnesium in the daily dose.
Is it better to take 2 or 4 capsules a day?
It's a trade-off between convenience and purity. Two capsules improve adherence for a long course of treatment. Four capsules of pure bisglycinate provide more chelated magnesium without resorting to oxide. Splitting the doses during meals remains the best way to proceed in all cases.
Why compare the cost per chelated milligram rather than the price of the bottle?
Because two products with similar prices can provide very different amounts of chelated magnesium. Here, SuperNutrition costs approximately €0.20 per 100 mg of chelated magnesium, compared to approximately €0.32 for Nutripure in its most advantageous format.
How long does it take for magnesium to take effect?
Generally, allow 2 to 4 weeks of regular intake to replenish your reserves. Regularity is the determining factor.
