A Single-Ingredient L-Tyrosine Supplement
L-Tyrosine is a non-essential amino acid — the body can produce it from phenylalanine, though dietary and supplemental intake is common among people who want a reliable daily source. It is the amino acid from which the body synthesises dopamine, noradrenaline, adrenaline and thyroid hormones. Each capsule in this formulation contains 500mg of L-Tyrosine as the free-form amino acid, in a vegan HPMC capsule shell, with no fillers, binders or added excipients of any kind.
Why People Choose L-Tyrosine
✔ 500mg free-form L-Tyrosine per capsule — the same form used in nutritional research
✔ No fillers, no binders, no flow agents — L-Tyrosine and the capsule shell only
✔ 120 capsules per bottle — a flexible supply, whether taken at one or two capsules daily
✔ A straightforward single-ingredient formulation with nothing unnecessary added
✔ Suitable for vegetarians; manufactured in the UK to GMP Code of Practice and ISO 9001
More Than a Typical Amino Acid Supplement
L-Tyrosine is present in many multi-ingredient formulations, but often at lower doses as part of a blend. This is a dedicated single-ingredient formulation at 500mg per capsule, making it well-suited for people who want to manage their intake without secondary ingredients. The free-form amino acid format means the dose is predictable and consistent with what appears in nutritional studies.
When People Take L-Tyrosine
L-Tyrosine has a following among people with demanding daily schedules — busy professionals, those with heavy training blocks, and people who want a considered approach to their amino acid intake. The recommended approach is one to two capsules daily, taken ideally on an empty stomach or with a carbohydrate-only snack, and not within three hours of bedtime. The flexible dose range means the supply from a 120-capsule bottle lasts between 60 and 120 days depending on individual preference.
About L-Tyrosine
Tyrosine was first isolated in 1846 from casein, a milk protein. It takes its name from the Greek word for cheese — tyros — reflecting that origin. As a non-essential amino acid, the body produces it from phenylalanine (an essential amino acid obtained from the diet). L-Tyrosine is the biologically active form. It is a precursor to the catecholamine neurotransmitters — dopamine, noradrenaline and adrenaline — and to thyroid hormones including thyroxine. L-Tyrosine is not on the GB nutrition register for any approved health effect; its widespread use in supplement formulations reflects its biological role as an amino acid.
