Product Info
What is Beta-Alanine?
Beta-Alanine is a naturally occurring non-essential amino acid widely used in dietary and sports supplements as a precursor to carnosine, which buffers muscle acidity to enhance physical endurance.
How is Beta-Alanine made?
| Step No. | Production Stage | Key Action | Control Point & Note |
|---|---|---|---|
| 1 | Synthesis (Ammoniation) | React acrylic acid with an excess of aqueous ammonia in a sealed pressure reactor. | The molar ratio of ammonia to acrylic acid is critical; excess ammonia is used to maximize yield and prevent side reactions. Temperature and pressure are tightly controlled to manage reaction rate and selectivity. |
| 2 | Purification (Ammonia Removal) | Heat the reaction mixture under vacuum to distill off the unreacted excess ammonia. | Temperature must be controlled to avoid product degradation. The efficiency of the vacuum system determines the rate of removal. Residual ammonia levels are monitored. |
| 3 | Decolorization & Filtration | Treat the crude beta-alanine solution with activated carbon to remove color and organic impurities, followed by filtration. | The quantity of activated carbon and contact time must be optimized to ensure effective decolorization without significant product loss. Filtration must completely remove all carbon particles. |
| 4 | Crystallization | Concentrate the purified solution by evaporating water and then cool it under controlled conditions to induce crystallization. | The cooling rate is a key parameter; slow cooling promotes the growth of larger, purer crystals. Solution concentration and pH (adjusted to the isoelectric point, ~6.9) are crucial for maximizing crystallization yield. |
| 5 | Centrifugation & Washing | Separate the solid beta-alanine crystals from the mother liquor using a centrifuge. The crystals are then washed. | Washing is typically done with a small amount of cold deionized water or ethanol to remove surface impurities without re-dissolving a significant amount of the product. |
| 6 | Drying | Dry the washed, wet crystals in a vacuum oven or fluid bed dryer until a constant weight is achieved. | Drying temperature is strictly controlled to be low enough to prevent thermal degradation or discoloration. The final product must meet the specified low moisture content (e.g., <0.2%). |
| 7 | Sieving & Packaging | Sieve the dried product to achieve the desired particle size distribution. Package the final product into clean, sealed containers. | Sieve mesh size is selected based on customer requirements. Packaging occurs in a controlled environment to prevent any foreign material or microbial contamination. Final QC analysis is performed on the lot. |

Applications & Usage
Common Applications:
Sports nutrition
muscle endurance supplements
pharmaceutical formulations
Mechanism of action:
| Parameter | Beta-Alanine |
|---|---|
| Functional Category | Nutritional Supplement; Intramuscular pH Buffer Precursor |
| Key Ingredients | β-Alanine (3-aminopropanoic acid) |
| Mechanism of Action | Acts as the rate-limiting precursor for the synthesis of carnosine (β-alanyl-L-histidine) in skeletal muscle. Increased carnosine concentrations enhance the intracellular buffering capacity, specifically against the accumulation of hydrogen ions (H+) during high-intensity anaerobic exercise. This mechanism helps stabilize muscle pH and delays the onset of neuromuscular fatigue. |
| Application Effect in Product | When formulated into supplements (powders, capsules, beverages), it provides the consumer with enhanced muscular endurance, increased training capacity for high-intensity efforts, and a delay in the perception of fatigue. It does not typically alter the physical or chemical properties of the food/beverage product itself. |
Comparison:
| Product Name | Category/Type | Key Features | Strengths (vs peers) | Weaknesses (vs peers) | Best Use Cases | Why Choose |
|---|---|---|---|---|---|---|
| Beta-Alanine | Amino Acid / Intracellular Buffer | Increases muscle carnosine levels to buffer acid. Often causes a harmless tingling sensation (paresthesia). Requires a daily loading phase for full effect. | Directly improves muscular endurance for sustained high-intensity efforts (1-4 minutes). Strong scientific backing for this specific use case. | Paresthesia can be uncomfortable for some users. Benefits are not felt acutely; requires consistent daily supplementation. | High-Intensity Interval Training (HIIT), rowing, mid-distance running (400m-1500m), sports with repeated high-effort intervals like soccer or hockey. | For its specific, proven ability to buffer muscle acidity and extend performance in activities where burning muscle fatigue is the primary limiting factor. |
| Creatine Monohydrate | Amino Acid Derivative / ATP Regenerator | Increases phosphocreatine stores for rapid ATP energy regeneration. The most researched sports supplement available. | Unmatched for improving maximal strength, power output, and performance in short, explosive bursts. Very cost-effective. | Less direct impact on buffering muscle acidosis. Can cause initial water weight gain. Primarily benefits efforts under 30 seconds. | Weightlifting, powerlifting, sprinting, any sport requiring repeated bursts of maximal power. | Choose for increasing raw strength and explosive power. |
| Sodium Bicarbonate | Alkalinizing Agent / Extracellular Buffer | Directly increases blood pH, acting as an external buffer to pull acid out of muscle cells. Very fast-acting. | Potent and acute performance enhancer for all-out efforts. Extremely inexpensive and readily available. | Very high risk of severe gastrointestinal distress (cramping, bloating, diarrhea). High sodium content is a concern for many. | Single, all-out competitive events lasting 1-7 minutes, like a cycling time trial or a 400m swim, where GI risk is worth the potential reward. | Choose for a cheap, powerful, single-dose boost for a key event, if you can tolerate the side effects. |
| Citrulline Malate | Amino Acid / Nitric Oxide Booster | Increases nitric oxide production to improve blood flow. Aids in clearing ammonia, a byproduct of exercise. | Enhances blood flow ("pump"), can reduce muscle soreness, and benefits both anaerobic and aerobic endurance without CNS stimulation. | Less potent for direct acid buffering compared to Beta-Alanine. Requires a relatively large dose (6-8g) for performance benefits. | High-repetition resistance training, general endurance activities, and for reducing delayed onset muscle soreness (DOMS). | Choose for improved endurance, muscle pumps, and better recovery, especially during volume-focused training. |
