Product Overview
Our fermented free‑form L‑Citrulline powder is a non‑protein‑building alpha‑amino acid manufactured under strict food‑grade fermentation workflows, delivering minimum 99.0% HPLC‑verified purity. Unlike L‑arginine, free‑form L‑Citrulline bypasses liver first‑pass breakdown after oral ingestion, helping the human body generate endogenous nitric oxide steadily to maintain endothelial vessel condition, support urea‑cycle ammonia elimination, and mitigate exercise‑triggered metabolic tiredness.
This clean‑label raw material contains zero malate compound, no filler agents, no artificial colorants or synthetic additives. It meets non‑GMO and clean‑formula criteria and fits multiple finished‑product development scenarios. The raw material passes multi‑level third‑party testing and holds global mainstream food safety credentials, satisfying anti‑doping and import compliance requirements for worldwide bulk purchasers.
Suited for sports supplement formulations, functional beverage blending, health food production, and pharma intermediate preparation. Important reminder: this raw material serves dietary formulation purposes only and cannot replace therapeutic drugs. Formulations targeting pregnant people, lactating mothers or children need professional medical assessment before adoption.

Frequently Asked Questions
Q1: What core distinction separates free‑form L‑Citrulline powder and L‑Citrulline Malate for finished‑product development?
A: Our free‑form L‑Citrulline is pure amino‑acid monomer without malic acid. L‑Citrulline Malate represents a salt complex combining citrulline and malate, featuring different dissolving performance and application positioning. If your formula requires precise citrulline content control, select free‑form L‑Citrulline raw powder.
Q2: Is this fermented L‑Citrulline raw material workable for organic‑certified finished‑product manufacturing?
A: Yes. Produced by non‑GMO fermentation, without irradiation processing and artificial additives, this raw material can fit clean‑label and organic‑compliant finished‑product formulation requirements. Please refer to our full supporting certification documents for your local organic filing procedure.
Q3: How should I store bulk L‑Citrulline powder to reach full shelf‑life performance?
A: Keep goods hermetically sealed, store inside cool, dry and ventilated warehouse environment, stay away from direct sunlight and humid atmosphere. Proper‑condition storage grants a 24‑month shelf life from manufacturing date. After partial opening of packages, seal tightly to prevent moisture ingress.
Q4: Could you furnish independent third‑party toxicology assessment and heavy‑metal test files for import registration?
A: We can provide complete document packages including Certificate of Analysis, heavy‑metal test statements, toxicology summary report and safety evaluation materials, which can be used for customs clearance and local regulatory registration work in target countries.
Q5: What delivery ways are available for my order of L‑Citrulline powder bulk goods?
A: For sample orders below 100 kg, door‑to‑door international express is available within 3‑5 working days. 100‑1000 kg orders choose airport‑to‑airport air freight (5‑7 days). Orders ≥300 kg can adopt sea port‑to‑port sea shipping around 30 days. Our team provides all required customs‑declaration paperwork.
Q6: Does this L‑Citrulline raw material contain common allergens such as soy, lactose or gluten?
A: Zero soy, milk‑derived components, gluten, peanut, tree‑nut and sesame ingredients are applied during our whole production workflow. Production lines avoid cross‑allergen contamination, making it suitable for allergen‑sensitive dietary‑supplement formula development.
Q7: What risks need formulators pay attention to when applying L‑Citrulline in finished dietary supplements?
A: This raw‑material is only for dietary‑supplement formula instead of therapeutic use. For formulas facing pregnant women, lactating groups and children, medical‑professional consultation is mandatory before launching finished‑goods. People taking hypotensive medication should be warned for potential interaction risks in finished‑product label copy.
Q8: Can I get technical guidance when combining L‑Citrulline with other amino‑acid raw materials in my new formula project?
A: Yes. Our technical department offers formulation‑support service for brand owners and food factories, including ingredient‑mixing reference, dissolving‑property debugging and compatibility evaluation with other amino‑acid substances.
