Citrulline malate, 400 mg
Citrulline passes the gut untouched and converts to arginine in the kidney, raising blood arginine more reliably than arginine itself. Ours is the DL-malate form, the one the performance research used.*
Steady Flow. Warmer Hands. Zero Stimulants.
Citrulline malate and arginine in one stimulant-free capsule pair, the precursor chain your body turns into nitric oxide, with every milligram printed on the panel.*

As seen in
Your body builds nitric oxide from arginine, so nearly every bottle on the shelf is an arginine bottle. The catch is what happens on the way in: a large share of an oral arginine dose is broken down in the gut and liver before it ever reaches your blood. Citrulline takes the long way around. It passes the gut untouched, converts to arginine in the kidney, and raises blood arginine more reliably than arginine itself.*
What most bottles do:
How Suppla Nitric Oxide is built instead:
Two capsules a day. That is the whole routine.
1. Warmer hands, livelier legs. Most of our customers notice it in daily life first: on morning walks, on cold mornings, on stairs that used to demand a pause.*
2. The workout pump. If you train, you will likely feel it there too: fuller, warmer muscles, the reason citrulline malate became a gym staple.*
3. Nothing else comes along. No jitters, no crash, no racing heart at 9pm. Stimulant-free means the only thing working is the blood flow support.*
What this formula does not do: it is not a blood pressure medication and it does not treat any condition. If you take blood pressure medication or nitrates, talk to your doctor before starting; the combination is exactly what a doctor should supervise.
Nitric oxide support works with your circulation day by day. This is the arc most people describe on two capsules daily, without skipping.
Days 1-7 · The Settling Phase. The habit locks in. Two capsules with water, any time of day, training day or not.*
Weeks 1-3 · The First Signals. Many notice the training pump first, then the everyday things: warmer extremities, livelier legs on stairs and walks.*
Weeks 3-8 · The Steady Build. Daily amino support is cumulative. This is the window where the routine starts feeling like a baseline, not an experiment.*
Weeks 8-12 · The Habit. The routine is invisible now. This is why the 3-month supply is the most popular choice.*
Consistency is the mechanism. Give it a full 60 days; the guarantee covers exactly that.
You train and want the pump without another scoop of caffeine. Or you are past 45 and circulation is the quiet thing you have started thinking about: cold hands, tired legs, the long sit at a desk.
You want the precursor that survives digestion, in the form the research used, next to the arginine it converts into, with every milligram printed. And you want it stimulant-free so it fits any hour and any stack.
Whether you are 30 and chasing a pump or 65 and chasing warmer feet, this is built for the daily habit.
Not for you if you want a caffeine hit, or if you take blood pressure medication or nitrates and have not cleared it with your doctor. We would rather you know before you buy.
Every bottle is manufactured in the USA. Orders ship within 1 to 2 business days and most arrive in 3 to 7 business days anywhere in the US. You get a tracking number by email the moment it ships. Subscriptions ship free.
Take Nitric Oxide daily for 60 days. If your training and your circulation do not feel different, email support@getsuppla.com. Full refund. No return required, no questions asked.
You have probably already spent money on arginine bottles that never made it past your gut, or powders that were mostly caffeine. This time the risk is on us. There is no downside to trying it properly.

The precursor that survives digestion, the amino it becomes, and zero stimulants hiding the difference. Two capsules a day.
Citrulline passes the gut untouched and converts to arginine in the kidney, raising blood arginine more reliably than arginine itself. Ours is the DL-malate form, the one the performance research used.*
L-Arginine HCl 350 mg plus AAKG 50 mg in the same capsule. Citrulline feeds arginine, arginine feeds nitric oxide. Carrying both covers the chain from either end.*
Every milligram is on the panel: 400 + 350 + 50. A blend total tells you nothing; a printed number can be compared with the research and with the bottle next to it.
No caffeine, no sucralose, no flavoring system. A cellulose capsule, rice flour, and the aminos. Take it at night, on rest days, or alongside anything else in your routine.

No scoops, no flavoring, no caffeine window to plan around. Two capsules with water, every day.

“I walk two miles every morning, rain or shine. Around week five my legs stopped feeling heavy on the hills and my hands stay warm the whole loop. My doctor knows what I take and had no objection.”
“Cold hands on the golf course every fall, like clockwork. A month on these and my hands stay warm through the round. My wife noticed before I said anything.”
“Cold hands and feet every winter since my forties. Half this category is caffeine powder; this is the opposite, two aminos and every milligram printed. Six weeks in, my hands finally stay warm.”
“Desk job, feet used to fall asleep by 3pm. Sounds small but that stopped around week three. I take two with lunch and that's the whole ritual.”
Not an arginine bottle your gut intercepts. Not a blend that hides the milligrams. Not a caffeine powder selling you the buzz. The precursor chain, printed.
