L-Citrulline & L-Arginine Stack - Nitric Oxide & Circulation Support - 400mg Citrulline & 400mg Arginine Per Serving - 30 Servings, Vegan Capsules

Nitric oxide is the signal that tells a blood vessel to widen, and your body builds it from two amino acids: arginine directly, and citrulline by converting it into arginine first.

How much of it actually arrives is the part worth knowing. 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, and what each is doing:

• L-citrulline DL-malate, 400 mg – the largest single amount in the serving, and deliberately the one leading the label
• L-arginine hydrochloride, 350 mg – the direct precursor, supplied alongside the citrulline rather than instead of it
• L-arginine alpha-ketoglutarate, 50 mg – the same amino acid in a second form, bringing the arginine in every serving to 400 mg across the two

And then two excipients and nothing else, which is what lets it sit alongside whatever your training week already involves.

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

• Blood flow support aimed at the muscle actually doing the work
• Endurance and training capacity backed every day of the block, rest days included
• Both nitric oxide precursors arriving daily, with citrulline weighted first

🩸 What is building underneath the block

Two capsules put both precursors into the pathway your body builds nitric oxide from, and that pool is filled by what arrives every day. Support for blood flow to working muscle is in place before a session starts rather than assembled in the twenty minutes before it. No stimulant, no flush and no tingle involved.

🏋️ It works on the days you are not training

Both precursors arrive on the Tuesday you trained and on the Sunday you did not, so the pathway behind blood flow to working muscle is supplied through the whole week. A hard block is won across all seven days, not only the four you are under a bar.

🧱 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.

Three amino acids, one pathway, taken every day of the block. Here is what that covers.

• Blood flow to working muscle – nitric oxide widens the vessel, and a wider vessel carries more oxygen and more nutrients to the muscle that is doing the work
• Endurance and training capacity – supported every day rather than around a single session, so what you have been building is there for the last set as well as the first
• Citrulline weighted first – first-pass breakdown is what a large share of swallowed arginine runs into. The citrulline route goes around it, which is why citrulline leads this label
• It is not for everyone – speak to your doctor first if you are pregnant or nursing, under 18, taking blood pressure medication, nitrates or a PDE5 inhibitor, if you have a history of cold sores, or if you have surgery coming up

The precursor pair at printed amounts, with two excipients and nothing else in the bottle.

This was made for people training through a block who want blood flow and endurance supported every day of it.

It's especially for you if:

• You want blood flow and endurance support running all week rather than only on the days you train
• You care what actually reaches your bloodstream, not only what is written on the front of the bottle
• You run more than one product and want this one to sit alongside them without doubling anything up
• You have been through a block where the last set was the first thing to go
• You want two excipients and nothing else in the capsule you are adding to the stack

Three actives and two excipients. 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 are pregnant or nursing, if you are under 18, or if you take blood pressure medication or nitrates without speaking to your doctor first.

Chances are, this is the citrulline and arginine stack you have been looking for.
