Going Beyond Protein
Whole proteins can require hours of complex digestion in addition to being bundled with undesirable micronutrients such as extra calories, fats, and carbohydrates.
For advanced healthcare, pharmaceutical, and food formulations, pure L-amino acids offer a highly efficient alternative. Because L-amino acids bypass complex digestion and are absorbed almost instantly into the bloodstream, their addition to formulations means faster, more targeted, and efficient benefits.
Ajinomoto Health & Nutrition is the industry leader in high-purity amino acid technology. Grounded in “AminoScience,” our products drive product innovation while delivering nutritional and functional benefits to improve global health outcomes.
Meeting the Challenge
Product developers are tasked with balancing clean label standards with superior taste profiles. Health-conscious consumers are demanding plant-derived, allergen-free, Non-GMO ingredients, and transparent product labeling. To satisfy this demand, Ajinomoto Health & Nutrition leverages advanced fermentation processes to generate high-purity L-amino acids.
Free-form amino acids can introduce a bitter flavor profile. Ajinomoto Health & Nutrition addresses this sensory hurdle with taste-masking innovations that enable R&D departments to provide substantial functional dosages while maintaining excellent flavor. This premium taste experience drives repeat purchases.
L-Amino Acid Ingredient Portfolio from Ajinomoto Health & Nutrition
Standard L-Amino Acids
L-Alanine
Supports cellular energy production, glucose metabolism, and stamina during high-intensity training.
L-Arginine
Acts as a precursor to nitric oxide, which expands blood vessels to improve blood flow, vascular health, and nutrient delivery.
L-Aspartic Acid
Helps combat fatigue and supports cellular energy production.
L-Cysteine
Functions as a key structural building block for skin, hair, and nails while promoting the synthesis of the master antioxidant glutathione.
L-Cystine
Provides structural stability to proteins like keratin and supports respiratory health.
L-Glutamic Acid
Serves as an important neurotransmitter for brain function and acts as a precursor for other vital amino acids.
L-Glutamine
Fuels immune cells and maintains the structural integrity of the intestinal lining for optimal gut health.
L-Histidine
Acts as a critical component for tissue repair and combines with beta-alanine to synthesize muscle-protecting carnosine.
L-Isoleucine
One of the three branched-chain amino acids (BCAAs) that stimulates glucose uptake into muscle tissue during exercise.
L-Leucine
The primary genetic trigger for muscle protein synthesis, making it essential for muscle growth and recovery.
L-Lysine
Critical for collagen synthesis, tissue repair, and supporting calcium absorption for bone health.
L-Methionine
Contains essential sulfur that protects tissues, clears heavy metals, and supports healthy liver function.
L-Phenylalanine
Acts as a direct precursor to L-tyrosine and key brain chemicals that regulate mood and alertness.
L-Proline
A foundational component of collagen that maintains the elasticity and health of skin, joints, and tendons.
L-Serine
Essential for proper brain function, cognitive health, and the formation of cell membranes.
L-Threonine
Helps build structural proteins like collagen and elastin while maintaining protective mucus barriers in the gut.
L-Tryptophan
Converts directly into serotonin and melatonin to regulate mood, sleep patterns, and emotional balance.
L-Tyrosine
Synthesizes neurotransmitters like dopamine and adrenaline to help the brain maintain focus and performance during stress.
Dipeptides and Specialty Derivatives
L-Alanyl-L-Glutamine
Formulated as a highly stable, hyper-soluble dipeptide that dramatically improves cellular hydration and electrolyte absorption.
N-Acetyl-L-Cysteine
Modifies standard cysteine for superior absorption, directly replenishing liver glutathione stores to neutralize free radicals.
N-Acetyl-L-Tyrosine
Enhances solubility and bioavailability over standard tyrosine to efficiently support cognitive function under cognitive fatigue.
N-Acetyl-DL-Tryptophan
Used primarily as a stabilizer in pharmaceutical and clinical applications to protect sensitive protein solutions.
Levodopa (L-DOPA)
Crosses the blood-brain barrier to directly convert into dopamine, supporting motor function and neurological health.
Taurine
Regulates cellular hydration, supports cardiovascular health, and aids neurological development.
Product Applications
Formulators can overcome traditional manufacturing challenges due to the versatility that pure L-amino acids provide across diverse product formats:
Beverage formulations:
Unlike intact proteins that can create chalky textures and grittiness, free-form L-amino acids are highly soluble and dissolve completely. This makes them ideal for refreshing beverages, waters, and clear sports drinks.
Functional foods:
Thermal processing often causes protein to lose its natural shape and structure, which in turn, ruins product texture and shelf life. Pure L-amino acids are heat-stable, which enables them to maintain integrity during baking. This format is perfect for fortifying bars, baked goods, and healthy snacks.
Dietary supplements:
L-amino acids maintain consistent particle sizes that ensure uniform blending. They mix smoothly into powdered formulas, sports nutrition shakes, and clinical medical nutrition products.
