L-Citrulline & L-Arginine Stack - 400mg Citrulline Malate & 400mg Arginine Per Serving - 30 Servings Vegan Capsules

If you have got as far as searching these two by name, you already know the outline: arginine is the direct precursor to nitric oxide, and citrulline is the amino acid your body turns into arginine.

The part that decides which bottle is worth buying is the bit most pages skip. A large share of swallowed arginine is broken down in the gut and the liver before it ever reaches your bloodstream. Citrulline slips past that and is converted in the kidneys instead, which is why it is generally the more dependable oral route to arginine than arginine is.

Three actives, printed:

• L-citrulline DL-malate, 400 mg – the largest single amount, and deliberately so. Note that this figure is the weight of the citrulline malate complex rather than of citrulline on its own
• L-arginine hydrochloride, 350 mg – the direct precursor, supplied alongside rather than instead of the citrulline
• L-arginine alpha-ketoglutarate, 50 mg – the smallest of the three, listed at its real size rather than given a prominence it has not earned

And then nothing else, which is the other half of the point. Two excipients, no stimulant, no nitrate blend, nothing that would muddy what you are actually testing.

KINETIC L-Citrulline & L-Arginine Stack is two capsules daily with 6 to 8 oz of water. Sixty capsules to a bottle. What you get for that:

• Both nitric oxide precursors, at amounts you can read and weigh yourself
• Support for healthy circulation, every day rather than around a session
• A clean single variable, if you are working out what these two actually do for you

🧪 Nothing to feel, and that is by design

No stimulant, no flush, no tingle. If you have felt your skin prickle on a pre-workout that was beta-alanine, and there is none in this bottle. A precursor habit is judged on consistency, not on a sensation twenty minutes in.

📐 Check our arithmetic before you buy

You are the kind of buyer who reads the panel first, so the panel is on the front of this page and the comparison against the research doses is a section below. If a page in this aisle will not give you both, that is usually the answer.

🧱 It stacks without overlapping

No caffeine, no creatine, no beta-alanine and no electrolytes. Whatever else is already in your routine, nothing in here doubles up on it, and that is deliberate for someone running more than one product.

💧 Two capsules, a full glass, every day

Six to eight ounces of water is the label direction and it is worth taking seriously, because amino capsules swallowed dry are the usual reason one sits badly. There is no window to hit and no need to time it around food or training.

You searched these two by name, so you will check this yourself. Here it is first.

• On the amounts, plainly – the human performance research on citrulline malate generally uses six to eight grams in one serving, and on arginine three to six grams. This serving is 400 mg and 400 mg. That is somewhere around a fifteenth to a twentieth of a studied performance dose, and it is why there is no pump, rep-count, endurance or recovery claim anywhere on this page. Once, in full, up front
• The malate ratio is not on the label – citrulline malate comes in different ratios and the free citrulline differs accordingly. Ours does not state which, so the citrulline is some amount below 400 mg and we are not going to publish an estimate dressed up as a label fact
• The arginine is the less efficient half – and it is on our own label, so we will say it. First-pass breakdown is exactly why citrulline is weighted first here. If a brand tells you plain arginine is the superior oral precursor, that is worth knowing about the brand
• What it is honestly for – supplying both precursors daily, in a short and readable label, as a nutrient habit. Smaller than the category promises, and true
• It is not a pre-workout – nothing here is stimulant, and nothing here is built to change how a single session feels

What is left is the precursor pair at printed amounts with nothing else in the bottle. If that is what you were looking for, this is it, and if you wanted the clinical serving you now know exactly what to compare against.

This was made for people who shop by ingredient rather than by front-of-bottle promise.

It's especially for you if:

• You searched for these two amino acids by name rather than for a category word
• You have turned a bottle round, found a proprietary matrix where the amounts should be, and put it back
• You run several products and want one that adds no caffeine, no creatine and no beta-alanine to the pile
• You want a clean single variable, because you are actually paying attention to what changes when you add something
• You would rather a brand told you its serving is a fraction of the research dose than let you find that out yourself

Three actives, every amount printed. Sixty vegetable capsules to a bottle, two a day. Gluten free, vegetarian, vegan friendly, allergen free and non-GMO. Made in the USA.

It is not for you if you want a clinical-serving citrulline product, if you are pregnant or nursing, if you are under 18, or if you take blood pressure medication or nitrates without speaking to your doctor first.
