Benario is a trading name/food ingredient brand backed by AuSaMicS Pty Ltd (ABN 56 676 640 467). This product is supplied as a food and nutrition ingredient for formulation use. It is not supplied as a finished dietary supplement or therapeutic good. Final formulation, dosage, nutrition claims, warning statements and label compliance are the buyer’s responsibility.
L-Arginine USP is typically used in dry powder systems such as amino acid premixes, protein powders, capsules, tablets and beverage powders. It is water-soluble, but it has a strong basic/bitter taste, so final-product testing is important for taste, pH, mouthfeel and label compliance.
💡 Taste and pH tip: L-Arginine free base can raise pH and create a strong alkaline/bitter taste. In drink powders, test with acids, flavours, sweeteners and minerals before approving the final formula.
Typical application guide
| Application | Typical use approach | Notes |
|---|---|---|
| Protein powders | Blend into dry premix | Use to adjust amino acid profile; check taste and pH |
| Amino acid blends | As per formulation spec | Combine with other amino acids according to target profile |
| Drink mixes | Dissolve/disperse with mixing | Manage basic taste with acids and flavour system |
| Capsules | As per formulation spec | Check flow, bulk density and fill weight |
| Tablets | As per compression formula | Validate compressibility and excipient compatibility |
| Food R&D | Small pilot batches | Check taste, pH, solubility and nutrition-labelling impact |
L-Arginine vs related forms
| Ingredient | Main role | Key formulation point |
|---|---|---|
| L-Arginine free base | USP amino acid ingredient | Basic taste; may raise pH; not the same as HCl salt |
| L-Arginine Hydrochloride | Arginine salt form | Different molecular weight, acidity and taste profile |
| L-Citrulline | Amino acid ingredient | Different identity and formula; often used in nutrition blends |
| L-Ornithine | Amino acid ingredient | Different amino acid; not interchangeable with arginine |
| L-Leucine | BCAA amino acid | More bitter and lower water solubility; different nutrition role |
| Glycine | Sweet amino acid | Milder, sweet taste; very different flavour profile |
Tips for use
- Pre-blend with other dry ingredients to improve uniform distribution
- For beverage powders, test acidity and flavour masking before scale-up
- Account for pH impact when used in drink mixes or acidic formulas
- For capsules/tablets, validate bulk density, flow and excipient compatibility
- Use accurate weighing for amino acid and nutrition formulations
- Request COA/source statement before making vegan, fermentation-derived, halal, kosher or non-GMO claims
- Do not make nitric-oxide, blood-flow, performance, medical or therapeutic claims unless approved for the finished product
⚠️ Claims caution: L-Arginine is widely discussed in sports nutrition and supplement marketing, but this page should stay ingredient-focused. Avoid unapproved claims such as blood flow, nitric oxide support, performance, fertility, cardiovascular benefit or disease treatment.
Storage
- Store tightly sealed in a cool, dry place
- Protect from moisture to maintain powder flow
- Keep away from strong odours and volatile flavours
- Use clean, dry utensils only
- Close container immediately after use
Usage information is general formulation guidance only. L-Arginine dosage, nutrition claims, warning statements and finished-product compliance depend on the intended product, serving size and market. Always run pilot trials before commercial production.
🧾 COA check: Confirm assay, identity, free-base form, source status, microbiology and heavy metals on the batch COA before commercial formulation. Do not assume the same specification as L-Arginine HCl.

Frequently asked questions
L-Arginine powder is used as a USP-grade amino acid ingredient in nutrition blends, protein powders, amino acid premixes, capsules, tablets, beverage powders and food formulation. It is supplied as an ingredient, not as a finished supplement or therapeutic product.
This product is L-Arginine free base. It is not L-Arginine Hydrochloride. The two forms have different molecular weights, taste profiles and formulation behaviour, so they should not be substituted gram-for-gram without recalculation.
Yes, L-Arginine is soluble in water. However, the free base form can have a strong basic/bitter taste and may affect pH, so beverage and drink-powder formulas should be tested for flavour, acidity, mouthfeel and stability.
This product page supplies L-Arginine as an ingredient only. Nitric oxide, blood-flow, sports-performance, fertility, cardiovascular or therapeutic claims must not be made unless they are legally permitted for the finished product in the target market.
Do not assume vegan, fermentation-derived, halal, kosher, non-GMO or allergen-free status unless confirmed by batch documentation. Request the COA and source statement before making source-sensitive claims.
L-Arginine free base has a naturally strong basic and bitter amino acid taste. In drink powders, it usually needs proper flavour masking with acids, flavours, sweeteners and mouthfeel agents.
The 100g pack is best for R&D and taste trials. The 250g pack suits repeated formulation testing. The 500g and 1kg packs are better for nutrition brands, small manufacturers and regular amino acid blending.
