Everything below sets out what citrulline malate 250g does, what may lawfully be claimed for it in Great Britain, and who should not bother. We would rather lose the sale than overstate it. The full citrulline malate 250g specification, price per serving and the alternatives worth considering are all further down this page.

Citrulline malate in a 2 to 1 ratio, unflavoured, at 6g per serving with 41 servings per tub.
Buying the individual ingredients and combining them yourself is almost always cheaper per session than buying a finished formula, and it lets you set your own caffeine dose or leave it out entirely.
Stack it with our beta alanine and taurine if you want to assemble the full thing.
Be warned that citrulline malate is genuinely sour on its own, so mix it into a flavoured drink rather than plain water.

Citrulline Malate 250g: dose, use and limits
Citrulline Malate 250g is stocked because for anyone who would rather build their own pre workout than buy a pre mixed one.

What citrulline malate 250g actually does
Citrulline is the answer to arginine’s problem. Swallowed arginine is largely destroyed before it reaches circulation; citrulline passes through and is converted to arginine in the kidneys, raising plasma arginine more effectively than arginine itself. That arginine feeds nitric oxide production, which dilates blood vessels and produces the sensation people call a pump. Bound to malic acid as citrulline malate, it also contributes to the citric acid cycle, which is the basis of the endurance findings.

Why this citrulline malate 250g in particular
Check whether the label states citrulline malate or pure citrulline, and in what ratio. A 2:1 citrulline malate product is two parts citrulline to one part malate, so six grams of citrulline malate is four grams of citrulline, and comparing across products without allowing for that is how people end up under dosing.
Buying citrulline malate on its own is the sensible way to get the one pre workout ingredient with decent evidence, at a dose that actually matches the research. Most pre workouts contain a fraction of the six to eight grams used in studies, because the ingredient is expensive and the tub has to hold a lot of other things. Buying it separately solves that entirely.
What we can and cannot claim about citrulline malate 250g
Supplement claims in Great Britain are constrained to an authorised register, which is why this section reads more narrowly than most of the category.
There is no authorised health claim for citrulline or citrulline malate in Great Britain. The pump and performance effects, whatever the research shows, cannot lawfully be claimed on the product.

What the evidence says about citrulline malate 250g
Some of this rests on good evidence and some on habit, so here is the split.
The evidence for citrulline malate is reasonable, with studies showing improvements in repetitions to failure and reductions in muscle soreness, typically at six to eight grams. It is one of the better supported pre workout ingredients and considerably better evidenced than the arginine it replaced. The effect is modest and most noticeable in higher repetition work.
Who citrulline malate 250g is for, and who should skip it
We would rather talk you out of this than sell it to the wrong person. Sensible for consistent trainers who want convenience rather than a transformation.
A poor choice for someone hoping it substitutes for food, sleep or consistent training. If you are in the second group, the honest advice is to close the tab.
Stacking citrulline malate 250g without doubling up
Combining supplements is where most people start paying twice for the same ingredient. One spreadsheet column per ingredient settles the question in five minutes.
Two products at half a useful dose each are not equal to one product at a useful dose. We would rather you bought one thing here and nothing else.
How to take citrulline malate 250g
Measure with the scoop provided and mix into water or whatever you normally drink. Powders give you control over the amount, which is their advantage over capsules, and the trade is that you have to actually do the measuring.
Mixing is easier if you add the liquid first and the powder second, which is the opposite of what most people do and the reason so many shakers end up with a lump in the corner.
Six to eight grams around thirty to sixty minutes before training. Check the ratio, since a 2:1 citrulline malate at six grams gives you four grams of actual citrulline.
What to expect from citrulline malate 250g, week by week
Judge this against a calendar rather than a feeling, and the whole category gets easier to assess. Treat the first fortnight as a baseline rather than a trial. If something is going to change, weeks four to eight is where it shows up.
At the three month point, be willing to conclude it did nothing for you. Keep one honest record and the question answers itself.
How to read the label on citrulline malate 250g
Before trusting a page about a product, read the product. Reference intake tells you about an average adult, which you may or may not resemble.
A generous serving size can make a thin dose look adequate, so read both numbers. Check the ingredient order too. Actives listed after the sweeteners and anti caking agents are present in token amounts whatever the front says.
Quality, testing and what you are trusting
Every product in this category makes similar claims, so the real variable is testing. Analytical surveys of sports supplements make consistently uncomfortable reading.
If a test failure would cost you something, buy only what has been batch certified. Our editorial policy covers how claims like these are checked before they appear.
Ordering citrulline malate 250g: delivery and returns
The shipping detail, up front, where it is useful rather than buried. Nobody handling the parcel learns anything from it, which matters more to some buyers than others. Every order is tracked, and the arrival window is calculated at checkout rather than guessed at here.
Change your mind on a sealed tub and the statutory window applies as written. A damaged parcel gets replaced or refunded on a photograph, not on a form.
Common mistakes with citrulline malate 250g
The same handful of mistakes come up again and again with this category, and none of them are complicated to avoid.
- Under dosing, since the research uses six to eight grams and many products contain far less
- Not allowing for the malate ratio when comparing citrulline content between products
- Expecting the pump sensation to indicate muscle growth, which it does not
None of those are unique to citrulline malate 250g, and all of them cost either money or the effect itself.
Citrulline malate 250g: what you are actually buying
Twenty three pounds for two hundred and fifty grams. At a proper dose that is roughly forty servings, which compares very well against pre workouts that under dose it.
The published specification is below. Cost per serving is the only fair comparison in this category, as nobody agrees on what a serving is.

Citrulline malate 250g: common questions
How much citrulline malate should I take?
Research showing benefit generally uses six to eight grams. Allow for the malate ratio when working out how much actual citrulline that is.
Can I add it to my pre workout?
Yes, and that is often the sensible move, since most pre workouts contain well below the researched dose.
How much citrulline malate should I take?
Research showing benefit generally uses six to eight grams. Check the ratio too, since a 2:1 product at six grams gives you four grams of actual citrulline.
Is the pump actually useful?
It is a blood flow effect rather than a growth effect. The performance findings around repetitions to failure are the more meaningful part of the evidence.
Is this suitable for teenagers?
Generally the simple products are, and the rest are not worth it at that age. Nothing on this site is intended for under 18s.
Why do some products list ingredients I cannot pronounce?
Flavour and texture ingredients, declared because they must be. The length of a chemical name tells you nothing about whether it belongs there.
Is a higher dose better?
No. There is a point where additional intake stops doing anything, and with a few ingredients it starts doing harm.
Do you sell anything I should avoid mixing this with?
No dangerous combinations exist within what we stock. Overlap is the problem rather than interaction, and with zinc and vitamin D that overlap can take you past a sensible intake.
What is the difference between your own brand and the branded products?
Cost structure. Our own label is cheaper because it is not funding a brand. Established brands offer a longer record, which is worth something and is not worth everything.
Do I need to take this with food?
Depends on the ingredient, and the label says which. As a rule anything fat soluble absorbs better with a meal, and anything that has ever made you queasy is better taken mid meal.
How do I know the tub contains what the label says?
You cannot verify it at home, which is why manufacturing standards matter more than branding. Where a product carries independent certification the page says so.
Do you offer a subscription?
No. A subscription is good for us and usually bad for the buyer, so we have left it alone.
Can I take this long term?
Yes, where it is correcting a shortfall that is still there. Put a date in the calendar to review it once a year rather than letting the subscription outlive the reason for it.
How quickly do you dispatch?
Orders are dispatched on working days, usually within one. You will get tracking, and a window that was calculated rather than advertised.
