  • Is produced in France in a high-quality laboratory with guaranteed traceability.

What is magnesium citrate?

Magnesium citrate is the combination of citrate and magnesium: two active molecules for athletes. 

This is the ideal form of magnesium to take before a workout. Citrate raises an athlete's pH, which has been lowered by the acid that the muscles generate during exertion. When the blood becomes too acidic, fatigue sets in more easily.

What are the benefits of magnesium citrate?

Guaranteed health of the athlete
Magnesium intake is necessary during intense and frequent physical exertion. Athletes needs to increase their magnesium intake by 10 to 20% above the recommended dose.

Boosted performance
There is a correlation between magnesium consumption and muscle mass. The higher your dietary intake of magnesium, the more muscle and better strength you have, even if you aren't athletic.

Protection of blood vessels
Magnesium also acts as an inhibitor of vascular calcification, which is very important because regular physical activity promotes the calcification of blood vessels.

Prevention of kidney stones
Magnesium citrate increases the pH of urine to dissolve stones before they can form.

Usage tips

Who is magnesium citrate for?

Nutrimuscle Magnesium Citrate is a supplement favoured by:

  • Athletes, to support their general health and improve performance
  • Inactive people who require a magnesium supplement

When should I take magnesium citrate?

In order to optimise absorption, it is particularly important to spread out your intakes into small doses throughout the day rather than taking one or two large doses per day.

Similarly, it's best to take Nutrimuscle Magnesium Citrate with meals, as protein and carbohydrates improve its assimilation.

How do I take magnesium citrate?

The more difficulty a person has assimilating magnesium, the more they will need to supplement with higher doses. 

But how do I know my magnesium assimilation is adequate or not?
The laxative effect of magnesium citrate comes more from the magnesium than from the citrate. So, if you are very sensitive to the laxative effect of magnesium, it is a sign that you assimilate it rather well. On the contrary, if no laxative effect occurs following a high intake of magnesium, it's a sign that you are not assimilating it very well. 

Similarly, migraines that are greatly reduced by regular use of magnesium are a sign of poor assimilation (49-50-51).

Increase dosages gradually
As with all supplements, it is advisable to start with a small dose of Nutrimuscle Magnesium citrate and progress slowly day by day if all goes well.
You can also add magnesium citrate to your water, which you can drink in small sips throughout the day.

No duplicated effect with Potassium Bicarbonate

Before a physical effort, the effect of citrate comes more slowly than that of bicarbonate. In addition, since the doses of magnesium citrate required to increase the blood pH are very high, the incidence of side effects in the digestive tract is very high (40).

The intake of 500 to 900 mg of citrate per kilo of body weight is used for studies, hence an intake of 40 to 80 g for an 80 kg athlete. However, the studies must be put into perspective: they test incredibly high doses, taken all at once. This is in no way relevant to athletes. Thus, they should start slowly to avoid digestive discomfort. The goal of supplementation is not to take as much as possible all at once, but rather to use a much more modest dosage on a regular basis.

The dosages and strategies of the studies should be ignored. This way, you'll avoid side effects, your performance will improve further, and you'll benefit from protective health benefits over time (see below; 41-42).

Conclusions: as a first step, bicarbonate intake should be retained. The addition of citrate will reinforce the effect of bicarbonate, allowing you to lower your intake if necessary (43).

In addition, magnesium citrate is much easier to use, since it can be taken with proteins, which is not the case with bicarbonate. And above all, magnesium citrate provides magnesium, while bicarbonate provides potassium, two minerals that are very both important to general health.

Benefits of Magnesium Citrate in more detail

Athlete's health assured

The goal of magnesium citrate supplementation is twofold. First of all, it aims to ensure the health of the athlete, who sees his magnesium requirements increase due to intense and regular physical exertion. The second objective is to optimize its performance and progress.

But the choice of this form of magnesium is not neutral, since magnesium citrate does not contain one, but two active molecules for the athlete. Like magnesium, citrate will also ensure the health of the athlete while increasing his performance.

Sport reduces magnesium levels because it speeds up the use and elimination of this mineral in sweat and urine. In other words, sport increases the need for magnesium (1-2-3-4-5-6).
This phenomenon of increased needs is particularly true in strength sports (7-8).

It is for these reasons that doctors recommend that athletes increase their magnesium intake by 10 to 20% compared to the basic recommendations (9).

Performance increase
Many studies have pointed to a correlation between magnesium intake and muscle mass. The higher the dietary intake of magnesium, the more muscle and strength people have, even the sedentary (10-11-12-13).
On the contrary, a magnesium deficiency is associated with a lower muscle mass.

Other studies show an improvement in performance and strength compared to a placebo, thanks to the intake of magnesium (14-15-16-17-18).

Several mechanisms of action are put forward. First, magnesium plays an important role in the process of muscle protein synthesis (anabolism) (19). Second, magnesium reduces the incidence of chronic inflammation and helps fight acidosis (20).

Likewise, in elite athletes, magnesium supplementation reduces muscle damage as well as DNA damage, which facilitates recovery between two workouts (21-22-23).

Magnesium intake could also serve to optimize testosterone secretion (24).
Finally, taking magnesium before exercise promotes glucose metabolism, helping to maintain blood sugar levels better, which fights fatigue (25-26).

Prevention of kidney stones
Medical research tends to show that intense physical activity can have a negative impact on the kidneys (44). Indeed, acidic urine promotes aggregation of kidney stones (45-46-47-48). The purpose of magnesium citrate is to increase the pH of the urine in order to dissolve stones before they can form.

Inhibition of vascular calcification
A low level of magnesium in the blood is associated with higher mortality with a higher incidence of cardiovascular disease and cancer (30-31-32-33-34). Magnesium also acts as an inhibitor of vascular calcification (35). This action is very important, especially in athletes, because the regular practice of a sporting activity promotes calcification of the blood vessels.

1. Magnesium contributes to electrolyte balance, strengthens muscle functions (neurotransmission and muscle contraction, including heart muscle) and protein synthesis.

2. Magnesium contributes to normal energy metabolism.

3. Magnesium contributes to the maintenance of normal nervous system functioning.

4. Magnesium helps to reduce fatigue and exhaustion.

5. Magnesium maintains bone health.

6. Magnesium contributes to good dental health.

Should we take magnesium citrate or use it non-stop?

The level of magnesium in magnesium citrate is 11.7%. So by taking 1 g of magnesium citrate, we get 730 mg of citrate and 117 mg of magnesium.

The average urine loss of magnesium is of the order of 100 mg per day. It is imperative to compensate them.

In Europe, the daily regulatory dosages for magnesium are 300 mg for women and 350 mg for men.

The needs of athletes are at least 10 to 20% higher. Although not regulatory, but recommended by the medical profession, the daily doses should take this into account.

The average intestinal absorption when things are going well is 30-50% of the magnesium ingested for a food intake of 370 mg per day.

The more magnesium you take, the more this absorption level is reduced, which can drop to 20%, hence the need to split your intake throughout the day.

Obviously, these are average values with some individuals having a much better assimilation rate, which considerably reduces their needs. On the contrary, in a person who has a lower than average absorption rate, combined with a high level of elimination, the magnesium requirement is found to be well above.

It is in these people that we find migraine sufferers, who respond well to high doses of magnesium. Likewise, in subjects suffering from classic intestinal problems, the absorption of magnesium is generally reduced.

Magnesium absorption does not improve with age, as it decreases over time. It seems wise to compensate for this decrease if we want to fully benefit from the effects of magnesium on our longevity.

It is because of this complexity of the assimilation mechanisms and those responsible for elimination that it is estimated that supplementation for at least 4 weeks is necessary to fully benefit from the effects of magnesium.

As the body stores magnesium poorly and the elimination of this mineral is constant, it is necessary to ensure a continual supply if one does not want to create a nutritional deficit. We therefore advise against taking cures that would consist of taking magnesium citrate for a period and then stopping it for a certain period of time.

What can be done is modulation of the intake according to your needs. These increase during periods of stress, intense training or when the weather is hot (since more magnesium is eliminated through perspiration). On the other hand, for people who suffer from migraines or who experience poor assimilation, we recommend a constant, relatively high intake throughout the year without taking a break.

ZMB and magnesium citrate, what's the difference?

If you are already taking ZMB Nutrimuscle, is it in your interest to take magnesium citrate as well or will it duplicate?

If you have an excellent absorption capacity for magnesium, adding magnesium citrate is not necessarily useful. On the other hand, if your assimilation capacities are not optimal, it is wise to add magnesium citrate to increase your magnesium intake (see below for clues that will help you assess your absorption capacities).

More than a magnesium intake, ZMB Nutrimuscle is above all a recovery supplement thanks to its content in pidolate, a relaxing amino acid. ZMB Nutrimuscle is best used in the evening, but not before a workout. Magnesium citrate can be taken throughout the day, in order to split the intake, in order to optimize its absorption (see below).
