⚖️ Formulation note: L-Leucine is a bitter, low-solubility BCAA powder. It should be tested in the final product for taste, dispersion, mouthfeel and label compliance before scale-up.
Benario L-Leucine Powder is a food-grade branched-chain amino acid ingredient for nutrition blends, protein powders, amino acid premixes, beverage powders, capsules, tablets and food formulation. L-Leucine is one of the three BCAAs alongside L-Isoleucine and L-Valine, and is used where a clean, single-amino-acid ingredient is required for food or nutrition formulation work.

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, food additive declarations and label compliance are the buyer’s responsibility.
L-Leucine is typically used in dry powder systems such as protein powders, amino acid blends, BCAA blends, capsules, tablets and beverage powders. It is functionally useful, but its bitter taste and limited water solubility mean formulation testing is essential before commercial launch.
💡 Taste-masking tip: L-Leucine can taste noticeably bitter. In drink powders, test with acidity, sweeteners, flavours, salt/mineral balance and mouthfeel agents 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 flavour impact |
| BCAA blends | Combine with L-Isoleucine and L-Valine | Commonly formulated with flavour and acid systems |
| Drink mixes | Disperse with strong mixing | Check solubility, foam, mouthfeel and sediment |
| 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, dispersion and nutrition-labelling impact |
L-Leucine vs related amino acids
| Ingredient | Main role | Key formulation point |
|---|---|---|
| L-Leucine | BCAA amino acid | Bitter taste; low water solubility; common in BCAA/protein blends |
| L-Isoleucine | BCAA amino acid | Structural isomer of leucine; different amino acid identity |
| L-Valine | BCAA amino acid | Used alongside leucine and isoleucine in BCAA systems |
| Glycine | Sweet amino acid | Mild sweet taste; much more taste-friendly in beverages |
| L-Glutamine | Amino acid ingredient | Different solubility, taste and nutrition positioning |
| Taurine | Amino sulfonic acid ingredient | Not a BCAA; common in beverage and nutrition products |
Tips for use
- Pre-blend with other dry ingredients to improve uniform distribution
- Use high-shear mixing or suitable processing for beverage applications
- Expect limited water solubility and possible floating/sediment in simple water systems
- Use flavours, acids and sweeteners to manage bitterness in drink powders
- For capsules/tablets, validate bulk density, flow and excipient compatibility
- For nutrition products, calculate amino acid contribution and label values accurately
- Do not make muscle-growth, recovery, medical or therapeutic claims unless approved for the finished product
⚠️ Claims caution: L-Leucine is widely discussed in sports nutrition, but this ingredient page should stay formulation-focused. Avoid unapproved claims such as muscle growth, recovery, performance, disease treatment or therapeutic benefit.
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-Leucine dosage, food additive declaration, nutrition claims and finished-product compliance depend on the intended product, serving size and market. Always run pilot trials before commercial production.
🧬 Identity note: L-Leucine and L-Isoleucine have the same molecular formula but are different amino acids with different structures and CAS numbers. Confirm identity by batch COA before formulation.

Frequently asked questions
L-Leucine powder is used as a food-grade amino acid ingredient in protein powders, BCAA blends, nutrition powders, capsules, tablets, beverage powders and food formulation. It is supplied as an ingredient, not as a finished supplement or therapeutic product.
Yes. L-Leucine is one of the three branched-chain amino acids, together with L-Isoleucine and L-Valine. It is commonly used in BCAA and sports-nutrition-style formulations, but finished-product claims must be assessed separately.
L-Leucine is commonly referenced as E641 / INS 641 when used as a flavour enhancer. Labelling depends on how the ingredient is used in the finished product, so commercial users should confirm the correct declaration before sale.
No. L-Leucine is only sparingly soluble in water and can float, clump or leave sediment in simple drink systems. Beverage formulas usually need proper mixing, flavour masking and dispersion testing before commercial production.
Many hydrophobic amino acids, including L-Leucine, have a bitter taste. In beverages and powders, bitterness should be managed with suitable flavours, acidity, sweeteners and mouthfeel agents.
This product is supplied as a food ingredient only. Muscle, recovery, performance or therapeutic claims must not be made unless they are legally permitted for the finished product in the target market.
The 100g pack is best for R&D and taste-masking 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.
