L-Tyrosine 500mg 60 Caps — Focus, Mental Energy & Stress Resilience (FSSAI Lab-Tested India)
About Zenith Sports
Zenith Sports is an Indian sports nutrition brand on a single mission: make lab-tested, easy-to-digest protein supplements that Indian athletes can actually trust.
Founded in 2020 and headquartered in Bangalore, Zenith Sports was built to fix two problems that quietly hurt every Indian gym-goer — bloating from cheap whey, and uncertainty about authenticity. Our answer was an 8-enzyme digestive blend in every whey and mass gainer, paired with a two-step QR-code authenticity check on every pouch you buy.
What makes Zenith different
1. 8-enzyme digestive blend in every protein SKU
Every Zenith whey and mass gainer is fortified with Protease, Lactase, Lipase, Amylase, Alpha-galactosidase, Gluco-amylase, Invertase and Cellulase. The blend helps break down protein and lactose efficiently, so you get maximum absorption without the bloating most Indian users associate with whey.
2. USA-imported whey concentrate at 80% protein-by-weight
Our raw whey is imported from the USA — one of the world’s highest-quality whey supply chains — and processed to a clean 80% protein-by-weight concentrate. No fillers, no artificial sweeteners in our unflavoured range, no banned substances.
3. Lab-tested every batch, with proof
Zenith Sports products are manufactured by Medizen Labs Pvt Ltd at our partner facility in Bangalore. The facility holds an FSSAI license (No. 11215332000675) and is GMP-certified. Every batch is third-party lab tested for heavy metals and adulterants — and we publish the test reports on our product pages, not behind an email gate.
4. Two-step QR authenticity check on every pack
Counterfeiting is the worst-kept secret in Indian supplements. We fight it with a two-step verification on every pouch: scan the QR code on the front, then scratch and scan the hidden Scratch QR code inside. Both must match at our verification page for the product to be authentic.
Who we are
Zenith Sports is operated by Meltingpot Concepts Pvt Ltd, headquartered in Bangalore, Karnataka. We are an India-first brand. Every product is formulated for Indian bodies, Indian climate, and Indian price points — the same protein quality international athletes buy, without the international markup.

Zenith Sports L-Tyrosine delivers 500mg per capsule. Tyrosine is a non-essential amino acid your brain converts into L-DOPA, then dopamine, then noradrenaline and adrenaline — the neurotransmitters that drive focus, motivation, and your stress response. Under high cognitive load, sleep deprivation, or acute stress, dopamine levels drop. Tyrosine supplementation maintains the precursor pool so synthesis can continue. Manufactured at our FSSAI-approved (License 11215332000675), GMP-certified facility in Bangalore. Vegetarian capsules.
The science
The neurotransmitter chain.
Your focus is downstream of dopamine. Your dopamine is downstream of tyrosine. No tyrosine, no dopamine.
Tyrosine enters the brain.
After ingestion, tyrosine crosses the blood-brain barrier through a specific transporter. Plasma levels peak around 60–90 minutes after dose.
Converted to L-DOPA.
The enzyme tyrosine hydroxylase — the rate-limiting step — converts tyrosine into L-DOPA inside dopaminergic neurons.
Dopamine production.
L-DOPA is rapidly converted to dopamine. Dopamine drives motivation, focus, and reward signaling. It's also the precursor to noradrenaline — the stress hormone that sharpens reaction time.
You feel clearer under pressure.
Studies in sleep-deprived military and emergency personnel show maintained cognitive performance with tyrosine supplementation during acute stress — the conditions where the brain otherwise burns through dopamine fastest.
Tested. Traceable.

Questions
The ones we get most.
When is tyrosine most useful?
High-stakes cognitive performance under fatigue — exams, presentations, long-haul travel, sleep-deprived training, demanding work shifts. It's not a daily focus pill so much as an under-stress focus tool.
Can I stack it with caffeine?
Yes. Synergistic for focus. Common stack: caffeine for arousal, tyrosine for dopamine precursor supply. Add L-Theanine to smooth the edge of the caffeine.
How quickly does it work?
60–90 minutes for peak plasma levels. Effect on focus is usually noticeable within that window when paired with a demanding task.
Side effects?
Generally well tolerated. People on thyroid medication should consult their doctor (tyrosine is also a thyroid hormone precursor). Avoid if you have hyperthyroidism.
Vegetarian?
Yes. HPMC capsule. Tyrosine is fermentation-derived.
FSSAI approved?
Yes. License 11215332000675. GMP-certified facility by Medizen Labs in Bangalore.
