Sinob Citrulline Malate - L-Citrulline Malate for Muscle Congestion

What is Sinob Citrulline Malate?

Sinob Citrulline Malate is a powdered L-citrulline malate for mixing, with no flavouring, no sweetener and no bulking agent. One 5 g scoop provides 3 g of citrulline malate as declared by the manufacturer, of which 1.875 g is L-citrulline, at a 2:1 ratio. It is taken one hour before training.

Citrulline is an amino acid the body makes itself and which is found above all in watermelon — Citrullus, hence the name. It serves as the raw material for arginine, which is itself the precursor of nitric oxide. That chain explains why citrulline has taken over from directly ingested arginine in pre-workout formulas.

The malate it comes paired with is not merely a manufacturing salt. It is malic acid, the molecule that gives a green apple its sharpness, and it is part of the cycle by which the cell produces energy. The 2:1 ratio means two parts citrulline to one part malate. The full German range can be browsed in our Sinob section, and the other products in the category in our citrulline section.

What does a dose of Citrulline Malate contain?

A point of honesty before going any further: the manufacturer's documentation contradicts itself on one detail. It states both an additive-free powder and 3 g of citrulline malate per 5 g scoop. We are reproducing the declared figures as they stand, without recalculating or correcting them. The official table appears on the packaging you will receive, and that is what counts.

What you need to know about dosages in this category, on the other hand, is perfectly clear. Published work on citrulline malate in strength training generally uses 6 to 8 g per serving. With one scoop, you are at 3 g. That is half a dose, and it is better to know it before buying: if you are aiming for the amounts used in the protocols, count on two scoops. The manufacturer allows for this itself, in fact, mentioning 6 to 8 g for sessions where the pump is the main objective.

On the regulatory side, let us be blunt: no health claim is authorised in Europe for citrulline. Not on performance, not on circulation, not on the muscle pump. So what we describe is an amino acid, its dosage and how to use it — not a promised result. The sensation of a pump during training is something many people report; it is not a claim, and we will not present it as one.

The manufacturer declares a powder with no allergens in the composition, suitable for vegan diets, gluten-free and lactose-free, and states that it is made in Germany.

Data missing from the manufacturer's documentation: the net weight of the tub, and therefore the number of servings, is not disclosed. We will not infer it; the net content is shown on the packaging.

Ingredients list

No allergens declared in the composition by the manufacturer.

How should Citrulline Malate be taken?

Dose: 5 g, i.e. one scoop, up to 6 to 8 g for long sessions. Liquid: 200 to 300 ml of cold water. Timing: 60 minutes before training. Frequency: one serving on training days; 3 g spread through the day for maintenance. Duration: no fixed course, occasional use around sessions.

Timing genuinely matters with this product, unlike many others. Sixty minutes is not a comfort margin: it is the time needed for citrulline to be absorbed, pass through the kidney and be converted into arginine. Taking it ten minutes before starting your session amounts to drinking it for nothing. If you are setting off from home, take it as you close the front door, not when you reach the changing room.

Dissolving it takes a little effort: citrulline malate is an acidic powder that settles at the bottom of the glass if you leave it standing. Shake it hard, drink it straight away, and rinse the glass — the acidity leaves a sticky residue if you wait.

The taste is decidedly sour and bitter, with no flavouring to mask it. That is the price of a pure powder. Two solutions: mix it into an already flavoured training drink, or add it to your usual pre-workout, where it will go unnoticed. Do not sweeten it at the last minute with fruit juice for a fasted session, as you would be adding carbohydrates without meaning to.

It combines without overlap with beta-alanine, which works through an entirely different mechanism, and with creatine monohydrate, whose value for strength is far better documented than that of citrulline.

Who is Citrulline Malate for, and who is it not for?

It is aimed at an adult training for resistance or endurance who wants to put together their own pre-workout rather than buy a ready-made formula. That is where its real value lies: a bare powder, dosable to the gram, with no caffeine or flavouring imposed on you.

It calls for caution if your blood pressure is low. The manufacturer mentions this explicitly, because of the vasodilatory effect expected from the arginine-nitric oxide pathway. Likewise, if you are on cardiovascular medication, an interaction is possible: that question is one for your doctor before you buy, and the answer cannot be guessed.

It is not recommended for pregnant or breastfeeding women without the advice of a healthcare professional. The manufacturer recommends starting at 3 g to assess your tolerance: that is sensible advice, digestive discomfort being the side effect most frequently reported with this kind of powder at high doses.

What not to expect from it. It does not replace a complete pre-workout: there is no caffeine here, no stimulant, no electrolyte. You will not feel a kick. It does not build muscle and it does not burn fat. And at 3 g per scoop, it is below the amounts used in the published protocols — that is the most important point on this page, and it is why we are repeating it.

Citrulline malate or arginine?

This is the most useful comparison in the category, and it settles fairly clearly.

Arginine taken orally undergoes substantial breakdown in the gut and the liver before it reaches the bloodstream. A sizeable share of what you swallow never arrives where it is supposed to act. That is a documented fact, and it is the reason citrulline has taken its place in most modern formulas.

Citrulline bypasses that stage: it is converted into arginine in the kidney, downstream of the digestive filter. At an equivalent dose, it therefore raises circulating arginine more than arginine itself does. That is the reasoning behind its commercial success, and it stands up.

When does arginine remain the right choice? When you are specifically after that molecule for a use documented elsewhere, or when you can find it at a solid dose for a lower budget. Our L-arginine section offers it in isolated form. And if you would rather have a complete stimulant-free formula, our pre workout without creatine section brings together ready-made products, generally dosed at 6 g of citrulline or more.

Frequently asked questions

How much citrulline per scoop?

3 g of citrulline malate as declared by the manufacturer per 5 g scoop, of which 1.875 g is L-citrulline at a 2:1 ratio. Published strength-training protocols tend to use 6 to 8 g of citrulline malate: count on two scoops if you want to get close to that.

Why take it an hour before the session?

Because citrulline has to be absorbed and then converted into arginine by the kidney before it has any effect at all. That journey takes time. A serving ten minutes before the warm-up arrives too late: sixty minutes is the interval the manufacturer settles on, and it is a coherent one.

What does this powder taste like?

Sour and bitter, with no flavouring to soften it. That is the trade-off of a pure powder, free of sweeteners and colourings. Most users mix it into an already flavoured training drink or into their usual pre-workout.

Citrulline malate or pure citrulline?

Malate is malic acid, a molecule from the cell's energy cycle, not merely a manufacturing salt. Weight for weight, a pure citrulline provides more citrulline; at an equal citrulline dose, the two are equivalent. Always compare the “of which L-citrulline” line, not the total weight.

Can it be combined with a caffeinated pre-workout?

Yes, without any overlap: citrulline is not a stimulant and provides no caffeine. That is in fact the most common way of using it, all the more so as its taste then goes unnoticed. Simply check that your pre-workout does not already contain some, otherwise you would be doubling the dose without knowing it.

Should it be taken on rest days?

It is not necessary. Unlike creatine or beta-alanine, which load into the muscle over several weeks, citrulline acts when you take it. The manufacturer does, however, mention 3 g spread through the day for maintenance, which remains optional.

Is this powder suitable for vegans?

The manufacturer declares a vegan product, gluten-free, lactose-free and with no allergens in the composition. It is a synthetically produced amino acid, with no raw material of animal origin.

Where can you buy Sinob Citrulline Malate?

The tub can be ordered from this page, and we ship anywhere in France and Europe. At the Vendargues shop, around ten minutes from Montpellier, this is the product we bring out for customers who want to put together their own pre-workout: a bare powder costs less than a ready-made formula and you decide on the dose. The rest of the range can be browsed in our sports nutrition selection.
