NOW Foods L-Citrulline 750 mg
Plain L-citrulline — nitric oxide and pumps without a pre-workout carnival
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.
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.
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.
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 sessionSome people notice a pump. Many notice nothing. Do not stack it the week you add four other new bottles.
GI
High dosesMalate powders upset more stomachs than capsules. Titrate.
Benefits
Stim-Free
Moderate EvidenceTrain at night without another 300 mg caffeine.
Known Form
Moderate EvidenceL-citrulline, not a proprietary pump blend with dyes.
Risks & Considerations
Blood Pressure Meds
medium riskNO-pathway supplements can interact. That is a clinician conversation if you are on antihypertensives.
Not a Hypertrophy Drug
low riskCreatine and protein still do more for muscle. This is optional.
