Citrulline Malate and L-Citrulline: what the published research says

PubMed indexes 8 records that name Citrulline Malate and L-Citrulline together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Citrulline Malate and L-Citrulline. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

8 studies naming Citrulline Malate and L-Citrulline.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Effects of Citrulline Malate Supplementation on Muscle Strength in Resistance-Trained Adults: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Journal of dietary supplements · 2022 · PMID 34176406

Meta-AnalysisSystematic ReviewHuman subjects

“The mean effects were similar for "limbs" (upper vs lower) [p = 0.763]. Accordingly, our findings suggest that citrulline malate supplementation does not improve muscle strength in healthy and resistance-trained individuals (PROSPERO registration number: CRD42020159338).”

Aguiar et al. · From the abstract

Names both Citrulline Malate and L-Citrulline in its title.

Short-term citrulline malate supplementation enhances lower-limb function in physically active older women: A pilot randomized controlled trial.

Clinical nutrition ESPEN · 2026 · PMID 42162613

Randomized Controlled Trial

“Six weeks of CM supplementation combined with multicomponent training was associated with improved sit-to-stand performance in older women, with additional favourable trends in walking endurance, SPPB score, and 25(OH)D. Given the pilot nature of the study, these findings should be considered preliminary and hypothesis-generating. Larger and longer trials are needed to confirm the reproducibility, clinical significance, and potential mechanisms of these effects.”

Ramos-Hernández et al. · Authors' conclusion

Names both Citrulline Malate and L-Citrulline in its title.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Citrulline Malate, L-Citrulline, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
