🧬 Amino Acid Supplements UK — Full Range

🔬 What Are These Amino Acids? — Ingredient Background

L-Tyrosine is a non-essential amino acid synthesised in the body from the essential amino acid phenylalanine. It is found naturally in protein-containing foods including meat, fish, dairy, eggs, nuts and beans. L-Tyrosine is the precursor to several neurotransmitters and hormones — including dopamine, noradrenaline (norepinephrine), adrenaline (epinephrine) and thyroid hormones T3 and T4. It is one of the most widely purchased individual amino acid supplements in the UK. Charge Products supplies L-Tyrosine in both vegan capsule and powder formats. Academic reference: NIH ODS — Amino Acid Dietary Supplements.

L-Theanine is an amino acid found naturally and almost exclusively in tea leaves (Camellia sinensis). It is not classified as an essential amino acid and has no established UK NRV. L-Theanine is one of the most researched amino acids in the context of relaxation and focus, having been studied for its effects on alpha brain wave activity. It is widely purchased as a standalone amino acid supplement and in combination with other nutrients. Charge Products supplies L-Theanine in both capsule and powder formats with a wide range of bulk sizes for retail and trade. Academic reference: PubMed — L-Theanine research review.

L-Arginine HCl is a conditionally essential amino acid — it can be synthesised in the body but dietary or supplemental sources may be relevant in specific circumstances. L-Arginine is found naturally in meat, fish, dairy, nuts and legumes. It is the biological precursor to nitric oxide (NO) via the action of nitric oxide synthase enzymes. L-Arginine is supplied here as L-Arginine Hydrochloride (HCl) — the salt form — which is stable and commonly used in supplement manufacture. Academic reference: PubMed — L-Arginine biochemistry.

Betaine HCl (Trimethylglycine) is an amino-acid-derived compound structurally related to the amino acid glycine. It occurs naturally in beetroot, spinach, quinoa and wholegrains. Betaine HCl (the hydrochloride form) is the supplemental form most commonly used in capsule and powder formats. Betaine is a methyl donor — it contributes to normal homocysteine metabolism, which is its one EU/UK authorised health claim under Regulation 432/2012. Academic reference: NIH ODS — Betaine and methyl donors.

Phenylethylamine (PEA) is a naturally occurring monoamine alkaloid found in trace amounts in the human body and in some foods. It is structurally related to the catecholamine neurotransmitters and shares its phenethyl backbone with several amino acid-derived compounds. PEA is supplied here in combination with L-Tyrosine in the L-Tyrosine & Phenylethylamine capsule format. No EU/UK authorised health claims exist for PEA.
