HelloPharmacist Scorecard of L-Citrulline 1,200 mg by LuckyVitamin

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: L-citrulline at 1,200 mg per dose. L-citrulline is an amino acid your body converts into another amino acid called L-arginine, which plays a role in blood vessel function and circulation.

The tablet also holds inactive ingredients (stearic acid, croscarmellose sodium, microcrystalline cellulose, coating, and silicon dioxide) — common fillers and binders that help the tablet hold together and move through your digestive system.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded L-citrulline's overall clinical evidence instead.

Moderate

Some clinical evidence supports L-citrulline for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Athletic performance — rated "Possibly Effective" (Natural Medicines).

L-citrulline is possibly effective for athletic performance — there's decent evidence it may help with endurance and muscle function. For sarcopenia (age-related muscle loss), the evidence suggests it is possibly ineffective.

For heart disease, heart failure, diabetes, and Reye syndrome, the evidence we hold is insufficient to say whether it works or doesn't. If you're taking it for one of those latter purposes, talk with your doctor about whether there's stronger evidence outside our data.

The evidence, ingredient by ingredient L-citrulline

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L-citrulline is generally well tolerated in healthy adults, though long-term safety hasn't been fully studied. The most common side effects are mild: gastrointestinal discomfort and heartburn.

A small number of people with pulmonary hypertension reported a cough, though that was at a much lower dose (1 gram) than this product. There is not enough safety data during pregnancy, so the evidence advises against use during pregnancy.

Safety while breastfeeding is unknown; the data suggests avoiding supplemental use at that time. Talk with your doctor or pharmacist if you're pregnant, planning pregnancy, or breastfeeding before taking this.

Side effects, ingredient by ingredient L-citrulline

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — L-citrulline.
  • The most serious interaction on file is rated Moderate.
  • For scale: 178 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, double-check any blood pressure medications (antihypertensive drugs) you're on — L-citrulline can theoretically add to their effect and lower your pressure more than intended (Moderate risk). Also check erectile dysfunction medications like sildenafil (Moderate risk of dangerously low blood pressure).

Use the medication checker below to run your exact drugs through, and talk to your doctor or pharmacist if you take either type.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

L-Citrulline may help with athletic performance if that's your goal, but it's not a proven fix for heart disease, heart failure, or diabetes. The real concern is its interaction with blood pressure and erectile dysfunction medications — both can be dangerously amplified.

If you're on either of those drug types, check your specific medications against the tool on this page and clear it with your doctor or pharmacist first. Otherwise, it's generally well tolerated, though stomach upset or heartburn can happen.

Formula

Citrulline is a non-essential amino acid that is an important intermediate in the urea cycle, functioning along with other amino acids to rid the body of ammonia, a by-product of protein metabolism. Citrulline also plays an important role in the healing process and in the maintenance of a healthy immune system.

L-Citrulline2 drug types · 178 drugs

Antihypertensive Drugs

Theoretically, concomitant use of L-citrulline with antihypertensive drugs might have additive effects and increase the chance of hypotension.
L-citrulline is converted to L-arginine, which can increase nitric oxide and cause vasodilation. However, a meta-analysis of 5 small clinical studies suggests that taking L-citrulline 3-6 grams daily for 1-8 weeks does not lower blood pressure when compared with control.

Likelihood Possible Evidence B
Phosphodiesterase-5 Inhibitors

Theoretically, concurrent use of phosphodiesterase-5 (PDE-5) inhibitors and L-citrulline might result in additive vasodilation.
L-citrulline is converted to L-arginine, which can increase nitric oxide and cause vasodilation. Theoretically, taking L-arginine with PDE-5 inhibitors might have additive vasodilatory and hypotensive effects. However, in studies evaluating the combined use of L-arginine and sildenafil for erectile dysfunction, hypotension was not reported.

L-Citrulline 1,200 mg by LuckyVitamin: Common Questions

Does L-Citrulline 1,200 mg by LuckyVitamin interact with any medications?
Yes. Based on its ingredients, L-Citrulline 1,200 mg has a known interaction with 178 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
L-Citrulline 1,200 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this help me build muscle or improve my workout?
L-citrulline is possibly effective for athletic performance, so there's some evidence it may support endurance or muscle work during exercise. But for age-related muscle loss specifically (sarcopenia), the evidence suggests it's not effective. Talk with your doctor about whether it fits your fitness goals.
Can I take this if I'm on blood pressure medication?
That depends on your specific drug — L-citrulline theoretically adds to blood pressure medications' effects and could lower your pressure too much. Check your exact medication against the tool on this page, and talk with your doctor or pharmacist before starting. They can tell you whether it's safe for you.
What side effects should I expect?
Most people tolerate it well. The most common side effects are mild: gastrointestinal discomfort and heartburn. A small number of people reported cough, though that was at a much lower dose. Stop and talk with your pharmacist if you have persistent stomach trouble.
Is this safe during pregnancy or breastfeeding?
There isn't enough safety data during pregnancy, so the evidence advises against it. Safety while breastfeeding is unknown too, so it's best to avoid it then as well. Talk with your doctor or pharmacist if you're pregnant, planning pregnancy, or breastfeeding.
Can I take this with my erectile dysfunction medication?
L-citrulline and drugs like sildenafil both work by widening blood vessels, so taking them together could cause an unsafe drop in blood pressure (Moderate risk). Before combining them, check with your doctor or pharmacist — they'll let you know if it's okay for you.
What does L-citrulline actually do in the body?
Your body converts L-citrulline into L-arginine, an amino acid that helps widen blood vessels and improve blood flow. That's why it may help with athletic performance and why it can interact with blood pressure and erectile dysfunction drugs.
