How to take it

One scoop (12.1 g) in water, 30 to 60 minutes before bed. One serving a day.

Training or intimacy instead? Take the same scoop 30 to 60 minutes beforehand.

Why before bed?

Your body does its repair work while you sleep, and repair runs on blood flow.

Most nitric oxide products are pre-workout powders built around a pump that is gone by dinner. NightNOX™ is built for the eight hours that actually matter - and it is stimulant-free, so it will not keep you up.

One Scoop. Whole Body Support*.

Nitric oxide tells your blood vessels to relax and widen — to your heart, your muscles, everywhere.

A hand holding a NightNOX shaker, linked to four icons: athletic performance, cardiovascular health, erectile function and healthy ageing.

Gym Performance

Blood flow gets oxygen to working muscle for strength, recovery and growth.

Cardiovascular Health

The lining of your blood vessels uses nitric oxide to stay healthy and flexible.

Erectile function

Erections are blood flow. Nitric oxide is what starts and maintains them.

Healthy ageing

Nitric oxide production declines with age. Supplementing it supports the vessels that depend on it.

Nobel Prize · 1998

Scientists were awarded the Nobel Prize in Physiology or Medicine for discovering nitric oxide's role in cardiovascular health.

Why Recommended before bed

Recovery happens at night.So does NightNOX™.

Sleep isn't downtime. Your heart rate slows, your blood pressure dips and your body shifts into recovery. This process runs on healthy blood flow and nitric oxide regulates it.

NightNOX™ before bed supports exactly that.

Need a boost before exercise or sex? Take your daily serving 30–60 minutes beforehand instead.

What's inside

9 precisely dosed ingredients. 4-in-1 Nitric Oxide Support System.

Pink NightNOX powder bursting from an open tub, beneath a panel showing four nitric oxide pathways: make, preserve, protect and support.
Make

Three different raw materials that your body can use to make more nitric oxide.

L-Citrulline

4,000 mg

Converts into arginine - the raw material your body uses to produce nitric oxide and works synergistically with L-arginine Nitrate.

Found naturally in: watermelon, cucumber and pumpkin

L-Arginine Nitrate (NO3-T®)

1,500 mg

Provides both arginine and nitrates, giving your body two extra complementary routes into nitric oxide production.

Found naturally in: nuts, seeds and soy (arginine); beetroot, arugula and spinach (nitrate)

Preserve

Keep more arginine available for your body to use to produce nitric oxide.

L-Norvaline

300 mg

Included to help preserve arginine by slowing the enzyme that breaks it down. Most nitric oxide supplements skip this.

Found naturally in: peanuts and other legumes

Protect

Help defend nitric oxide against oxidative stress.

L-Glutathione

250 mg

An antioxidant that pairs with citrulline to help protect nitric oxide availability from oxidative stress.

Found naturally in: asparagus, avocado and spinach

Folate as 5-MTHF

800 mcg

The active form of folate, protecting the enzyme that blood vessels use to produce nitric oxide.

Found naturally in: leafy greens, legumes and citrus

Vitamin C

100 mg

Supports the formula's antioxidant action and helps protect nitric oxide from premature breakdown.

Found naturally in: citrus fruit, peppers and berries

Support

Support the vascular environment and your sleep that nitric oxide depends on.

Pine Bark Extract

125 mg

Standardized to 95% proanthocyanidins to support vascular function and antioxidant defenses.

Found naturally in: the bark of the maritime pine

Taurine

1,500 mg

Supports healthy vascular function, sleep and cellular balance at a meaningful daily dose.

Found naturally in: shellfish and fish — and made by the body itself

L-Theanine

200 mg

Supports a calm evening routine without sedating you.

Found naturally in: green tea and black tea

Serving size one scoop (12.1 g), 30 servings per container. Made in the USA in a GMP-certified facility. Vegan. Photographs and source lines show where each compound occurs in nature — NightNOX™ contains purified, individually dosed ingredients, not these foods.

FAQs

What is NightNOX™?

NightNOX™ is a nightly nitric oxide system. Nitric oxide is the signal that tells your blood vessels to relax and widen, and your body produces less of it as you age.

Most formulas stop at supplying more raw material. NightNOX™ works four ways: make nitric oxide, preserve the arginine it is built from, protect it from oxidative breakdown, and support the vascular environment it depends on.

Nine active ingredients, led by 4,000 mg L-citrulline and 1,500 mg L-arginine nitrate (NO3-T®), with every dose printed on the label. No proprietary blends. Mixed berry, vegan, stimulant-free, and made in the USA in a GMP-certified facility.†

Who is NightNOX™ for?

Men over 18 who want to support healthy blood flow — for training and recovery, for cardiovascular health, for erectile function, or simply because nitric oxide production declines with age.

If you take medication for blood pressure or erectile function, or you have a medical condition, talk to your doctor before starting.

How do I take NightNOX™?

One scoop (12.1 g) mixed with water, 30 to 60 minutes before bed. One serving a day.

Daily use is the point. Nitric oxide support is not something you top up occasionally — the formula is built around consistency.

Why take it before bed?

Because your body does its repair work while you sleep, and repair runs on blood flow. It is also when healthy nighttime erections happen.

Most nitric oxide products are pre-workout powders built around a temporary pump that is gone by dinner. NightNOX™ is built for the eight hours that actually matter.

Will it keep me awake?

No. NightNOX™ contains no caffeine and no stimulants of any kind — that is deliberate, because it is designed to be taken at night.

It also includes 200 mg of L-theanine, which supports a calm evening routine without sedating you.

Can I take it before training or sex instead?

Yes. Take your one daily scoop 30 to 60 minutes beforehand instead of at bedtime. Either way it is one serving a day.

How long until I notice anything?

Results vary from person to person. This is the pattern the formula is built around.

Tonight. Citrulline and arginine nitrate begin working within hours, for an acute nitric oxide boost that supports blood flow for exercise, recovery and intimacy.

First month. All nine ingredients become part of your daily routine and support shifts from occasional to constant. You may begin to notice fuller pumps, better exercise performance and healthier nighttime erections.

From 90 days. Consistent use provides longer-term support for your vascular system — blood flow, recovery, cardiovascular health and sexual function. Ninety days is the beginning, not the finish line.†

Will it help my performance in the gym?

NightNOX™ supports healthy blood flow, and blood flow is how oxygen and nutrients reach working muscle — during training and during the recovery that follows. L-citrulline in particular has been studied specifically in the context of exercise performance, and 4,000 mg is a full studied dose.

It is built to support the work you are already putting in, not to replace it. Individual results vary.†

Can I use it alongside the Adam Sensor?

Yes, and this is something no other supplement can offer. The Adam Sensor tracks your nighttime erections, which depend on nitric oxide and healthy blood flow.

It does not measure nitric oxide directly — nothing worn on the body does — but it does let you follow your own trend over months instead of guessing. Most supplements ask you to take their word for it.

What is actually in it?

Serving size one scoop (12.1 g), 30 servings per container. L-Citrulline 4,000 mg, Taurine 1,500 mg, L-Arginine Nitrate (NO3-T®) 1,500 mg, L-Norvaline 300 mg, L-Glutathione 250 mg, L-Theanine 200 mg, Pine Bark Extract 125 mg, Vitamin C 100 mg, Folate 800 mcg as 5-MTHF.

Of the 12.1 g scoop, about 8 g is active ingredient; the rest is flavour and mixing agents, all listed on the label. No proprietary blends.

Can I take it with medication?

If you take medication for blood pressure or erectile function, or you have a medical condition, ask your doctor before starting. Nitric oxide affects blood vessels, and so do several common medicines.

When will it ship?

NightNOX™ is on pre-sale now. Orders ship in November.

Available in the United States only.

What if it's not for me?

Try it. If NightNOX™ isn't for you, tell us within 30 days of delivery and we'll refund you in full — no questions asked.
