NOW Foods L-Citrulline 750mg review — unflavored nitric-oxide and endothelial blood-flow capsules without pre-workout stimulants or artificial sweeteners.

Plain L-citrulline — nitric oxide and pumps without a pre-workout carnival

4.5
(2,800 retailer reviews)

NOW’s 750 mg L-citrulline capsule is the cheap, unflavored way to try the arginine precursor Huberman and pre-workout labels talk about. Performance literature often uses 3–6 g of citrulline malate — this bottle is 750 mg per cap, so you are counting capsules, not sipping a candy tub. Pair with creatine; skip the 20-ingredient pre-workout.

How It Works

Citrulline → arginine → nitric oxide. Performance effects are modest and better studied as citrulline malate at gram doses. This is not a blood-pressure drug and not a replacement for Zone 2.

1

Arginine Precursor

Citrulline raises plasma arginine better than oral arginine for many people. Nitric oxide is the marketing word; pumps and a bit of performance are the usual claims.

2

Dose Honesty

750 mg is a convenient cap. Training studies often sit at grams. Four to eight capsules is a real protocol — or buy powder later if you stay on it.

3

No Stimulant

This SKU is citrulline only. Caffeine stays in coffee or a separate pill. See the caffeine guide.

What You'll Experience

Lifts

Same session

Some people notice a pump. Many notice nothing. Do not stack it the week you add four other new bottles.

GI

High doses

Malate powders upset more stomachs than capsules. Titrate.

Benefits

Stim-Free

Moderate Evidence

Train at night without another 300 mg caffeine.

Known Form

Moderate Evidence

L-citrulline, not a proprietary pump blend with dyes.

Risks & Considerations

Blood Pressure Meds

medium risk

NO-pathway supplements can interact. That is a clinician conversation if you are on antihypertensives.

Not a Hypertrophy Drug

low risk

Creatine and protein still do more for muscle. This is optional.

Mixed Reviews

Pump believers vs ‘felt nothing.’ Smart comments all say you need grams, not one capsule.

Creatine Dose: 5g Daily for Muscle, Bone, and Brain

Take 5 g of creatine monohydrate every day for muscle, bone, and brain. You do not need a separate higher daily dose for bone — the bone research is still early and is studied with lifting, at ordinary doses. Some short brain studies use about 10–20 g a day, split up. That is a research protocol, not the daily dose this guide uses. Saturation from 5 g a day is the default.

L-Citrulline Guide: How Long It Lasts, Daily Dose (3–6g) & Malate

How long does L-citrulline or citrulline malate last, and how much should you take per day? Oral L-citrulline peaks in the bloodstream about 45–60 minutes after ingestion and its nitric-oxide vasodilation and workout 'pump' effects last roughly 3 to 6 hours (with baseline endothelial benefits extending longer with daily use). Clinical exercise studies use 3 to 6 grams of pure L-citrulline (or 6 to 8 grams of 2:1 citrulline malate) taken 30–60 minutes before training. This guide covers exact dosing, duration, and why [NOW Foods L-Citrulline 750mg](/equipment/now-foods-citrulline) is a stimulant-free nitric oxide staple on Amazon.
