ABOUT INDIVIDUAL AMINO ACID SUPPLEMENTS
Amino acids are compounds the body uses to build proteins and perform numerous physiological functions. They contribute to muscle tissue, enzymes, neurotransmitters, hormones, connective tissue, energy metabolism, and many other biological processes.
Our Individual Amino Acid Supplements collection at Coal Harbour Pharmacy features pharmacist-curated single-amino-acid and closely related formulas that allow more targeted supplementation than broad-spectrum amino acid blends.
Choose from options such as L-Glutamine, L-Theanine, L-Tyrosine, L-Lysine, L-Arginine, L-Citrulline, Glycine, Taurine, L-Tryptophan, L-Carnitine, NAC, and individual BCAAs, available in capsules, tablets, powders, and other convenient formats.
KEY BENEFITS
Depending on the specific amino acid, supplementation may help:
• Support muscle protein synthesis and recovery
• Support exercise performance and endurance
• Maintain healthy nervous-system function
• Support calmness, focus, and mental performance
• Provide building blocks for neurotransmitters
• Support connective tissue and collagen formation

WHAT ARE AMINO ACIDS?
Amino acids are organic compounds that combine to form proteins.
The amino acids used to build proteins are generally categorized as:
Essential Amino Acids
These cannot be produced in sufficient quantities by the body and therefore must be obtained through the diet.
They include:
• Histidine
• Isoleucine
• Leucine
• Lysine
• Methionine
• Phenylalanine
• Threonine
• Tryptophan
• Valine
Non-Essential Amino Acids
The body can normally synthesize these amino acids, although they remain important for normal physiological function.
Conditionally Essential Amino Acids
Under certain circumstances—including illness, injury, growth, or significant physiological stress—the body’s requirements for some normally synthesized amino acids may increase.
AMINO ACIDS FOR MUSCLE & PERFORMANCE
L-Leucine
Leucine is an essential branched-chain amino acid (BCAA) with an important role in signaling muscle protein synthesis.
Commonly selected for:
• Muscle-building nutrition

Beta-Alanine
Beta-alanine is used to produce carnosine, a compound concentrated in skeletal muscle.
Supplementation is particularly associated with exercise-performance applications involving repeated or sustained high-intensity activity.
A harmless tingling sensation known as paresthesia can occur with larger individual doses.
AMINO ACIDS FOR MUSCLE & TISSUE RECOVERY
L-Glutamine
Glutamine is abundant in the body and is involved in numerous metabolic processes.
It is commonly incorporated into nutritional protocols supporting:
• Exercise recovery
• Intestinal-cell nutrition
• Immune-cell metabolism
• Increased physiological demands
Glycine
Glycine contributes to:
• Protein synthesis
• Collagen formation
• Glutathione synthesis
• Nervous-system signaling
It is also commonly used in evening wellness and sleep-support routines.
L-Proline
Proline is particularly important as a structural component of collagen.
It contributes to:
• Connective tissue
• Skin structure
• Cartilage
• Tendons and ligaments
• Normal tissue repair
AMINO ACIDS FOR FOCUS, STRESS & SLEEP
L-Theanine
L-theanine is an amino-acid-related compound naturally occurring in tea.
It is commonly used to support:
• Relaxation without pronounced sedation
• Calm focus
• Stress management
• Mental performance
It is frequently combined with caffeine in focus-oriented formulations.
L-Tyrosine
Tyrosine is used by the body in the production of catecholamines such as dopamine and norepinephrine, as well as thyroid hormones.
It is often selected for cognitive support during periods of acute stress or demanding mental activity.
L-Tryptophan
Tryptophan is an essential amino acid and a biochemical precursor to serotonin and melatonin.
It is commonly used in formulations supporting:
• Sleep
• Relaxation
• Mood-related nutritional support
L-Serine
Serine participates in numerous metabolic and neurological processes and is an important component of proteins and cell membranes.
AMINO ACIDS FOR METABOLIC & CELLULAR SUPPORT
L-Carnitine
Carnitine helps transport long-chain fatty acids into mitochondria, where they can be used for energy production.
Different forms of carnitine are available depending on the intended nutritional application.
Taurine
Taurine is an amino-sulfonic acid found throughout the body, particularly in the heart, brain, muscles, and eyes.
It contributes to several physiological processes involving:
• Cellular function
• Electrolyte balance
• Cardiovascular function
• Nervous-system function
L-Alanine
Alanine participates in glucose and amino-acid metabolism and plays a role in energy metabolism, particularly between muscle and liver tissue.
L-Methionine
Methionine is an essential sulfur-containing amino acid involved in methylation pathways and the production of several biologically important compounds.
L-Ornithine
Ornithine participates in the urea cycle, through which the body processes nitrogen produced during amino-acid metabolism.
AMINO ACIDS FOR IMMUNE & ANTIOXIDANT SUPPORT
L-Lysine
Lysine is an essential amino acid required for normal protein synthesis.
It also contributes to:
• Collagen formation
• Tissue maintenance

NAC is a derivative of cysteine and an important precursor used in the synthesis of glutathione.
It is commonly incorporated into nutritional protocols supporting:
• Antioxidant defenses
• Glutathione production
• Respiratory health
• Cellular protection
Histidine
Histidine is an essential amino acid involved in protein synthesis and serves as a precursor to histamine.
It also contributes to several metabolic and physiological processes.
WHAT ABOUT 5-HTP, GABA & COLLAGEN?
Some products commonly grouped with amino acids are technically different from individual protein-forming amino acids.
5-HTP
5-Hydroxytryptophan is a naturally occurring metabolic intermediate between tryptophan and serotonin.
Because it directly affects serotonin pathways, potential medication interactions—particularly with serotonergic medications—should be carefully considered.
GABA
Gamma-aminobutyric acid is an inhibitory neurotransmitter rather than one of the standard protein-building amino acids. It is commonly sold as a nutritional supplement for relaxation and stress support.
Collagen Peptides
Collagen peptides are not an individual amino acid. They are mixtures of small peptides naturally rich in amino acids such as glycine, proline, and hydroxyproline.
They are generally better categorized under collagen or connective-tissue support.

FAQ
Do I need individual amino acid supplements if I eat enough protein?
Not necessarily. A varied diet containing adequate high-quality protein generally supplies essential amino acids. Individual supplementation is more useful when targeting a particular nutritional or performance goal.
Are BCAAs individual amino acids?
Leucine, isoleucine, and valine are individual essential amino acids collectively known as branched-chain amino acids (BCAAs).
Which amino acid is best for muscle growth?
Leucine plays an important signaling role in muscle protein synthesis, but muscle growth ultimately requires adequate total protein, all essential amino acids, sufficient energy intake, and appropriate resistance training.
Which amino acid is best for relaxation?
L-theanine and glycine are commonly used in relaxation-oriented supplements, while L-tryptophan is involved in serotonin and melatonin synthesis. They work through different mechanisms.
Can I take several individual amino acids together?
Sometimes, but combining them is not automatically beneficial. Large amounts of individual amino acids can compete for absorption or create unnecessary imbalances.
Are amino acid supplements vegan?
Many are produced through fermentation and can be vegan, but sourcing varies. Check the individual product label.
Are 5-HTP and GABA amino acids?
They are commonly grouped with amino-acid supplements, but neither is one of the standard protein-forming amino acids.
CAUTIONS & WARNINGS
