Naturally occurring compound that supports physical performance during high-intensity exercise.
L-carnitine is a quaternary amino-acid derivative, chemically described as β-hydroxy-γ-trimethylaminobutyric acid, naturally present in the human body and in foods, especially those of animal origin. In supplements it is commonly used as free-form L-carnitine or as salts/esters that supply L-carnitine, such as L-carnitine L-tartrate, acetyl-L-carnitine, and propionyl-L-carnitine. These forms appear in capsules, tablets, powders, or liquids, with serving amounts varying widely depending on the formula. In cosmetics it may be included as a functional ingredient in leave-on or rinse-off products, typically at low concentrations and declared on the INCI list. On labels it can also appear as “carnitine” or under the specific form name, clearly indicating the source of the active substance. As a raw material it is typically offered with standardized purity and is often used in blended formulas alongside other amino acids, vitamins, or other supplement ingredients.
N-acetylcysteine (NAC) is a derivative of the amino acid L-cysteine in which the amino group is acetylated; on labels it may also appear as N-acetyl-L-cysteine or acetylcysteine. It is a small, water-soluble organosulfur compound that is chemically related to cysteine found naturally in proteins and in human metabolism. In food supplements it is typically supplied as a powder or in capsules/tablets containing NAC as the primary ingredient, sometimes in blends with other amino acids. In cosmetics it may be present under the INCI name “Acetyl Cysteine”, used in water-based formulas such as serums or skin-care products. As a raw material, NAC is commonly identified by its chemical name “acetylcysteine” and standard identifiers such as a CAS number, while specifications can differ by purity grade and supplied form.

Choline is a water-soluble organic compound often grouped with the B-complex family, occurring naturally in foods such as eggs, meat, fish and legumes, and also present in the body as part of phospholipids. In supplements it is used as choline bitartrate, choline chloride, alpha-GPC (L-alpha-glycerylphosphorylcholine) or citicoline (CDP-choline), and also via lecithin as a source of phosphatidylcholine. On labels it may also appear as “total choline” calculated from these sources. In cosmetics, choline derivatives and phospholipids can be used in formulas as components of liposomal delivery systems or within conditioning blends, typically in leave-on or rinse-off products. Choline is commonly presented in capsules, tablets, powders or liquids, often combined with phospholipids or other lipid-matrix ingredients. Composition and concentration depend on the chemical form and on how the raw material is standardised.
L-arginine is a proteinogenic amino acid found naturally in protein-rich foods and in the body as part of amino-acid metabolism. In supplements it is commonly used as L-arginine in powders or capsules, and also as different salts/complexes chosen for handling and solubility, such as L-arginine hydrochloride (HCl) or arginine alpha-ketoglutarate (AAKG). On labels it may also appear as “free form” (base) or as part of amino-acid blends and pre-workout style formulas. As a raw material, L-arginine is a white crystalline powder, often hygroscopic, that is mixed into drinks or filled into capsules. In cosmetics it is seen less often in water-based formulas as an amino acid/conditioning component, typically at low concentrations and alongside other amino acids.
Chondroitin sulfate is a glycosaminoglycan, meaning a long polysaccharide built from repeating disaccharide units, naturally present in connective tissues and especially in cartilage. In food supplements it is most commonly listed as “chondroitin sulfate” or as a sodium salt, supplied as capsules, tablets, powders, or sachets. Traditional raw-material sources include bovine, porcine, avian, and cartilaginous fish cartilage, while some products use chondroitin sulfate made via microbial fermentation followed by sulfation. Composition and molecular weight can vary with the source and purification process, so labels often specify the form and origin. In cosmetics it may appear as a skin-conditioning/humectant ingredient in topical formulas, typically using water-soluble derivatives and low concentrations suited to leave-on or rinse-off products.

Coenzyme Q10 is a lipophilic benzoquinone (ubiquinone-10) that occurs naturally in human cells and in many foods in small amounts. In food supplements it is typically provided as ubiquinone (the oxidised form) or ubiquinol (the reduced form), commonly dispersed in oils or microencapsulated for softgels, capsules or powders. In cosmetics it is most often declared under the INCI name “Ubiquinone” and is used in emulsions such as face creams, eye-area products, serums and body lotions. As a fat-soluble molecule, it is usually formulated into the oil phase and paired with other formula antioxidants to support stability. On labels it may also appear as “ubidecarenone”, a naming variant used in some markets for the same substance. Cosmetic- and supplement-grade material may be produced by fermentation or synthesis and then standardised for purity.
