HelloPharmacist Scorecard of L-Citrulline 3000 mg Capsules by BulkSupplements.com

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, an amino acid your body converts to another amino acid called L-arginine. The capsule itself is made with bovine gelatin.

L-citrulline is included at 3000 mg per serving.

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. For other uses — including sarcopenia (muscle loss with age), heart failure, cardiovascular disease, diabetes, and Reye syndrome — the evidence either points to little benefit or isn't strong enough yet to say whether it works.

The data we hold doesn't establish reliable evidence for those conditions.

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 gastrointestinal — heartburn and stomach discomfort.

A small number of patients with pulmonary hypertension reported cough when taking it. For pregnancy, there isn't enough safety data, so you should avoid this supplement during pregnancy.

The same applies to breastfeeding — safety is unknown, so supplemental use isn't advised. Talk with your doctor or pharmacist about whether L-citrulline is right for you if you're pregnant, planning to become pregnant, or breastfeeding.

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, check with your doctor or pharmacist if you're on blood pressure medications or erectile dysfunction drugs (like sildenafil). Both can have additive lowering effects on your blood pressure when combined with L-citrulline.

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, but it can lower blood pressure and shouldn't be mixed with blood pressure or erectile dysfunction medications without your doctor's approval. It's generally well tolerated, though digestive upset can happen.

Talk with your doctor or pharmacist before starting, especially if you take any medications or have heart or blood pressure concerns.

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 3000 mg Capsules by BulkSupplements.com: Common Questions

Does L-Citrulline 3000 mg Capsules by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, L-Citrulline 3000 mg Capsules 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 3000 mg Capsules 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.
What is L-citrulline supposed to do?
L-citrulline is an amino acid your body converts to L-arginine, which helps relax blood vessels and improve blood flow. The evidence shows it's possibly effective for athletic performance. For other uses — like heart failure, cardiovascular disease, and diabetes — the data we have isn't strong enough to say whether it works.
Can I take this if I'm on blood pressure medication?
No — not without checking with your doctor first. L-citrulline can lower blood pressure, and mixing it with blood pressure drugs might cause your pressure to drop too far. Talk with your own doctor or pharmacist about your specific medications before starting.
What are the side effects?
Most people don't have problems, but heartburn and stomach discomfort are the most common side effects reported. A small number of patients with pulmonary hypertension reported cough. Long-term safety hasn't been fully studied.
Is this safe during pregnancy or breastfeeding?
No. There isn't enough safety data during pregnancy, so you should avoid this supplement if you're pregnant or planning to become pregnant. Safety while breastfeeding is also unknown, so avoid supplemental use then too. Talk with your doctor or pharmacist if you have questions about whether L-citrulline is right for you.
What's in the capsule besides L-citrulline?
The capsule is made with bovine gelatin. That's the only other ingredient — the rest is L-citrulline at 3000 mg per serving.
Can I take this with erectile dysfunction medications?
Check with your doctor first. Erectile dysfunction drugs like sildenafil lower blood pressure, and L-citrulline does too — combining them could cause your blood pressure to drop too much. Your doctor or pharmacist can tell you whether it's safe for your situation.
