The L-Arginine L-Ornithine L-Lysine trio is one of sports nutrition’s classic combinations — three amino acids the gym tradition has stacked together since the 1980s, pressed by Fits into a single tablet: 361.75 mg arginine, 300 mg ornithine and 225 mg lysine per tablet, 120 tablets per pack.

Three aminos, three roles

• L-arginine — the conditionally essential amino acid, famous throughout sports nutrition as the precursor in the body’s own nitric-oxide chemistry
• L-ornithine — arginine’s metabolic partner in the urea cycle, the pairing that made the two inseparable on supplement labels for four decades
• L-lysine — a genuinely essential amino acid the body cannot make, obtainable only from food and supplements, and a structural regular in the body’s protein work

Why the trio travels together

This exact three-way combination is a piece of gym-culture heritage: the classic stacks of the golden era paired arginine and ornithine, lysine joined for its essential status, and the formula has survived every subsequent fashion cycle on loyalty alone. Fits’ contribution is the modern audit — each amino quantified per tablet, hydrochloride forms named, and the excipients (cellulose, dicalcium phosphate, hypromellose coating and colleagues) printed where marketing usually lives.

How to take it

One tablet a day, preferably early in the morning, per the label. Do not exceed the stated dose. Standard cautions apply with feeling: pregnancy and breastfeeding call for medical advice; anyone on blood-pressure medication should specifically discuss arginine with their pharmacist; and herpes-prone customers may know lysine and arginine’s folk rivalry — another conversation your pharmacist handles well. Food supplements complement a protein-adequate diet; no tablet out-argues a chicken breast.

Who buys the trio?

Veterans of classic sports nutrition who’ve stacked these three since before the internet; pre-workout minimalists who prefer heritage combinations to neon blends; and amino-acid completists building shelves one named compound at a time alongside our taurine and glycine.

Frequently asked questions

Why morning dosing? The label’s tradition — the classic stacks were morning-and-training-day creatures; consistency matters more than the hour.

Tablet size? A standard pressed tablet — one swallow, once a day, 120 days per pack: a full four-month run.

Vegetarian? The coating is hypromellose (plant-derived) — no gelatine in this one.

Heritage stacks, modern expectations

Supplement culture has a habit of rediscovering its grandparents — and the arginine-ornithine-lysine trio is due its reappraisal on modern terms: not the breathless promises of the magazine era, but stated milligrams, named forms and a four-month runway per pack. Run it the way heritage deserves: one tablet, mornings, alongside actual training and actual protein, evaluated across a season. The stack’s endurance through forty years of fashion cycles is itself the most honest testimonial available — formulas without loyal users don’t survive four decades on shelves.

Combine with creatine and protein? The classic architecture — this trio predates them as stack-mates by decades; label doses all round and the three coexist as they always have.

Powder equivalents? For arginine-family powders the market leans pre-workout blends — the tablet is the way to keep this trio’s doses under your own control.

Why hydrochloride forms? Stability and solubility — the HCl salts are how these aminos have always been pressed reliably; the facts table states the free-amino equivalents.

Training-day only or daily? The label reads daily — heritage stacks were built as routines, not event supplements; pick the pattern and hold it.

Age guidance? Adult sports nutrition — teenagers’ protein questions belong with food first and professionals second.

Empty stomach or with breakfast? The early-morning label tradition implies before food; sensitive stomachs may prefer alongside it — either way, same slot daily.
