USP Grade HCl Salt Form Food Grade Lab Tested COA Available
L-Lysine Hydrochloride is the HCl salt form of L-Lysine — an essential amino acid that must be obtained through diet. USP grade, offering superior purity and stability compared to free-form L-Lysine. The most limiting essential amino acid in plant-based proteins (cereals, grains), making it critical for plant-based EAA blends, protein fortification and complete nutritional formulas. Pure food-grade powder with excellent water solubility and a mildly salty taste.
🧪 USP Grade (United States Pharmacopeia) — one of the highest internationally recognised standards for purity and quality. Meets strict requirements for identity, assay, heavy metals and microbial limits. Preferred for pharmaceutical, nutraceutical and premium food applications.

💡 Dosing note: L-Lysine HCl contains ~80% free L-Lysine. To deliver 1g of L-Lysine, use approximately 1.25g of L-Lysine HCl. Always calculate based on the lysine content, not the total weight of the salt.
Benario is a trading name of AuSaMicS Pty Ltd (ABN 56 676 640 467). This product is a food-grade ingredient intended for use in food manufacturing and nutritional formulation. It is not a therapeutic good and is not intended to prevent, treat or cure any disease.
L-Lysine HCl is the most critical amino acid to include in plant-based and cereal-based nutritional formulas. It is the first limiting essential amino acid in virtually all grain-based protein sources.
Recommended usage levels
| Application | Typical inclusion rate | Notes |
|---|---|---|
| EAA / plant-based protein blend | 1 – 5% | Most limiting EAA in grain-based proteins — always include |
| Cereal / bread fortification | 0.1 – 0.5% | Mix into dry blend before processing |
| Functional drink / nutritional beverage | 500 mg – 2 g per serve | Dissolve in water — mildly salty taste |
| Meal replacement / MRP | 500 mg – 2 g per serve | Standard inclusion in complete protein formulas |
| Animal / poultry feed | As per formulation spec | Most limiting EAA in corn-soy diets |
| General food use (powder/capsule) | 500 mg – 3 g per serve | Typical inclusion rate in nutritional products |
Lysine in plant-based protein fortification
| Protein source | Lysine status | Recommendation |
|---|---|---|
| Wheat / wheat flour | Severely limiting | Add L-Lysine HCl at 0.2–0.4% of flour weight |
| Corn / maize | Severely limiting | First limiting EAA — essential to supplement |
| Rice protein | Limiting | Include in complete rice protein blends |
| Oat protein | Limiting | Improves PDCAAS score significantly |
| Pea protein | Adequate | Less critical but useful in complete EAA blends |
| Soy protein | Adequate | Less critical — soy is relatively lysine-rich |
💡 Formulation tip: L-Lysine is the first limiting amino acid in most grain-based foods (wheat, corn, rice, oats). Including L-Lysine HCl in plant-based EAA or protein fortification blends is the single most impactful step for improving the nutritional quality of cereal-based products. The HCl salt form is preferred for liquid applications due to its superior solubility versus free-form L-Lysine.
Tips for use
- Dissolve in water before adding to liquid formulas for even distribution
- Mildly salty taste — consider flavour masking in consumer-facing products at higher doses
- Stable under normal food processing temperatures — suitable for most manufacturing conditions
- For capsule or tablet use, blend with excipients before compression
- Remember: 1.25g L-Lysine HCl = 1g free L-Lysine equivalent
Storage
- Store in a cool, dry place away from direct sunlight and moisture
- Keep container tightly sealed after every use
- Shelf life: 24 months from manufacture date when stored correctly
- Avoid moisture exposure — may clump; break up before use

Frequently asked questions
L-Lysine HCl (hydrochloride) is the salt form of L-Lysine — it is more stable, more water soluble and has a longer shelf life than free-form L-Lysine. The HCl salt form is the industry standard for food and nutritional applications. The lysine content of L-Lysine HCl is approximately 80% (the remainder is the HCl component), so adjust dosing accordingly when substituting.
USP stands for United States Pharmacopeia — one of the highest internationally recognised quality standards for pharmaceutical and food-grade chemicals. USP grade specifies strict requirements for identity, purity, potency and quality. It meets or exceeds standard food grade and FCC (Food Chemicals Codex) requirements.
L-Lysine is the first limiting essential amino acid in most grain-based foods — wheat, corn, rice, oats and barley are all deficient in lysine. This means that without lysine supplementation, plant-based protein sources cannot support complete protein synthesis. Adding L-Lysine HCl to plant-based EAA blends and cereal-based foods directly addresses this deficiency and significantly improves the nutritional quality.
L-Lysine HCl has a molecular weight of 182.65 g/mol, while free L-Lysine has a molecular weight of 146.19 g/mol. The lysine content of L-Lysine HCl is therefore approximately 80.1% (146.19 ÷ 182.65). To deliver 1g of L-Lysine, use approximately 1.25g of L-Lysine HCl.
Yes. This product is manufactured via fermentation of plant-based feedstocks and is suitable for vegans and vegetarians. It is gluten-free and contains no animal-derived ingredients.
Yes. Email info@benario.com.au with your order number for a batch-specific Certificate of Analysis including assay, heavy metals and identity confirmation per USP specifications.
The 100g and 500g packs suit R&D, small-batch testing and home use. The 1kg and 2.5kg are ideal for regular commercial production. The 5kg is best value for food manufacturers, animal nutrition producers and bulk buyers.
