L-Tyrosine is a conditionally essential amino acid — the body produces it from phenylalanine, but dietary intake matters when endogenous synthesis is insufficient. It is the biosynthetic precursor to dopamine, noradrenaline, adrenaline and the thyroid hormones T3 and T4. It is naturally found in high-protein foods including chicken, turkey, fish, dairy, eggs, nuts and seeds. Educational context — food supplement, not a medicine.

Biosynthesis
Produced from phenylalanine via phenylalanine hydroxylase · our supplemental form is produced via bacterial fermentation of maize glucose
Downstream Molecules
L-Tyrosine → L-DOPA → Dopamine → Noradrenaline → Adrenaline
Also → Thyroid hormones T3 (triiodothyronine) and T4 (thyroxine)
Natural Food Sources
Chicken · turkey · fish · dairy · eggs · nuts · seeds · soy · avocado

🌱 Fermentation-Derived — Why Source Matters
Not all L-Tyrosine is produced the same way. Most inexpensive L-Tyrosine on the market is extracted via acid hydrolysis of animal-derived proteins — including animal hair, feathers and other protein by-products. Our L-Tyrosine is produced via bacterial fermentation of plant-based glucose substrates (maize) — the same clean production method used in pharmaceutical amino acid manufacturing.
| Factor | Fermentation-Derived ← Ours | Animal Hydrolysis |
|---|---|---|
| Source | ✅ Maize glucose — plant-based | Animal hair, feathers, protein hydrolysis |
| Production method | ✅ Bacterial fermentation — clean process | Acid hydrolysis of animal protein |
| Vegan status | ✅ Fully vegan — no animal materials | Not vegan |
| Capsule shell | ✅ HPMC — plant cellulose | Usually gelatin — animal collagen |
| Label transparency | ✅ Clearly labelled vegan | Often unspecified or unmarked |
| Pharmaceutical standard | ✅ Same method as pharma-grade production | Budget grade |
⚖️ Why There Are No Authorised Health Claims for L-Tyrosine
L-Tyrosine is a widely studied amino acid — but no authorised EU/UK health claims exist for it as a food supplement ingredient under Regulation 1924/2006. This is the honest position and it applies to all L-Tyrosine supplements on the UK market.
What we can say (factual and biochemical):
L-Tyrosine is the biosynthetic precursor to dopamine, noradrenaline, adrenaline and thyroid hormones T3 and T4. This is established biochemistry — not a health claim. Educational context only.
What we cannot claim:
We cannot claim L-Tyrosine supplements "support focus," "boost dopamine," "reduce stress," or "improve cognitive performance" — these are unapproved health claims under UK food law. Any supplement brand making these claims is non-compliant. We don't make claims we cannot legally support.
✅ What this means for you: All L-Tyrosine content on this page is factual specification and biochemical educational background only — not health claims. The biochemistry is real. The regulatory position is what it is. Food supplement — not a medicine.

💡 How to Use & Store
Suggested use: 1–2 capsules per day as directed on the label. Can be taken with or without food.
MAOIs: Do not take L-Tyrosine if you are on monoamine oxidase inhibitors (MAOIs) without GP guidance — L-Tyrosine is a precursor to catecholamines which MAOIs prevent from breaking down, potentially causing elevated blood pressure.
Thyroid medication: L-Tyrosine is a precursor to thyroid hormones T3 and T4. Consult GP before use if on levothyroxine or other thyroid medication.
Storage: Cool, dry place below 25°C, away from direct sunlight. Reseal securely after use. Food supplement — not a medicine.
