Answer:
Not assessed by our current pair rules.Quick take
- •NutriAudit has no specific interaction rule for L-citrulline + L-arginine. The pair remains unassessed in our rules; ingredient references do not establish combination safety.
- •Our rules do not establish whether L-citrulline and L-arginine compete for absorption. A missing warning does not establish that there is no competition.
- •The main warning is false confidence. “No known interaction” does not mean every dose is safe once multiple products and body conditions are layered together.
Timing: No L-citrulline + L-arginine timing recommendation is established by our current rules. Use the product instructions and ask a pharmacist about your exact formulations and medications; this page does not recommend a spacing interval.
Full-stack warning: A pair lookup does not cover your full stack. Duplicate ingredients, high doses, medications, pregnancy, or medical conditions require a separate review.

Frequently Asked Questions
Can I take l-citrulline and l-arginine together?
Our database does not currently assess this pair with a specific interaction rule. That is a coverage gap, not evidence that the combination is safe. Review both product labels, total intake, medications, and relevant health conditions with a clinician or pharmacist.
If no pair rule is listed, what should I check next?
Look at upper limits, duplicate intake from multiple products, and whether pregnancy, kidney-stone history, or cardiovascular issues change the safe range.
