FitNox® (Plant Nitric Oxide Complex)

Evidence Level
Limited
1 Clinical Trial
3 Documented Benefits
2/5 Evidence Score

FitNox® is a plant-based nitric oxide complex combining moringa (Moringa oleifera) leaf, pomegranate (Punica granatum), and black ginger (Kaempferia parviflora). It is designed to boost the body's nitric oxide for better blood flow and stamina.

Studied Dose Around 250 mg per day.
Active Compound Blend of Moringa oleifera leaf, pomegranate, and black ginger (Kaempferia parviflora) extracts.

Benefits

Nitric oxide and blood flow

In a randomized single-dose study, FitNox significantly increased nitric oxide levels in serum and saliva (a short-term surrogate marker), consistent with support for vasodilation and blood flow.

Supported by Trial 1

Exercise support (mechanistic)

The single-dose study measured only nitric oxide in serum and saliva; endurance and muscle fatigue were not assessed. Any exercise-performance link is a mechanistic extrapolation from the acute rise in nitric oxide.

Supported by Trial 1

Energy and stamina

By supporting nitric oxide and blood flow, FitNox is positioned to support energy and workout stamina; effects on fatigue and stamina have not been directly measured.

Supported by Trial 1

Mechanism of action

1

Nitric-oxide enhancement

The plant blend supports the body's production and protection of nitric oxide, which relaxes blood vessels for better blood flow.

2

Antioxidant protection of NO

Pomegranate polyphenols help protect nitric oxide from being broken down, prolonging its blood-flow benefits.

Clinical trials

1
Plant NO Complex and Nitric Oxide — RCT
PubMed

Randomized single-dose study on enhancement of nitric oxide in serum and saliva with a natural sports supplement. (Jacob et al. 2018, Journal of Dietary Supplements)

Healthy adults.

The supplement significantly increased nitric oxide levels in serum and saliva versus control.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated.
Mild digestive upset is occasionally reported.
Avoid taking late if it feels energizing.

Important Drug interactions

Blood pressure medication — nitric-oxide boosters may add to blood-pressure lowering; monitor.
Erectile-dysfunction drugs (PDE5 inhibitors) — possible additive effect; consult a doctor.
Tell your doctor if you take cardiovascular medication.
