What is in LactiGo.

What are the ingredients in LactiGo?

Menthol 1.5% is the one active ingredient, and seven inactive ingredients make up the rest: ethoxydiglycol, glycerin, L-carnosine, magnesium sulfate, phenoxyethanol, water and xanthan gum. That is the list on the FDA-listed label, in label order.

Why is carnosine listed as “inactive”? Because on a US over-the-counter label, “active” is reserved for the ingredient that makes the drug claim — here, menthol for minor aches. Carnosine’s job is performance, and that is what the trials measured.

What does the carnosine in LactiGo do?

Carnosine is the reason LactiGo exists. It is a dipeptide your muscle already uses to buffer the acid that builds up in hard efforts, and it is the ingredient every LactiGo trial studies.

• 2025, triple-blind: world-class rugby sevens players produced 5–10% more peak power on LactiGo than on a placebo with the same menthol — 1426 W vs 1270 W in sprint 7.
• 2016, field test: Serie A footballers ran 3 × 1000 m about 4% faster with LactiGo.
• 2021, absorption: in racehorses, topical carnosine raised muscle carnosine about 35% within 30 minutes and about 46% at 60 minutes.

What is the menthol for?

Menthol is the cooling you feel and the label’s active ingredient: at 1.5% it makes the menthol version an over-the-counter topical analgesic for the temporary relief of minor aches and pains of muscles and joints. It is also the ingredient sceptics point to — so the 2025 trial put the same menthol in its placebo, and LactiGo still won on peak power.

The shop page lists the menthol at 1.25% and the DailyMed label at 1.5%; the brand’s FAQ notes there may be minor differences depending on territory. Either way the carnosine, not the tingle, is what the trial isolated.

What is the difference between LactiGo with menthol and Original?

Only the menthol. LactiGo Original — the menthol-free version, also called Regular — has the same carnosine, magnesium sulfate and gel base, no scent, and the same $55 price for 100 ml.

Which LactiGo version should you choose?

Choose menthol if you want the version the trial compared against a menthol placebo, plus the cooling feel and label relief of minor muscle aches. Choose Original if you dislike the tingle, have skin that reacts to menthol, or train in close contact with partners — grapplers and fighters often do.

• Game day, racing, hard intervals: with menthol, the tested version.
• Grappling, close-contact sport, sensitive skin: Original.
• Kit bag and travel: Original Go Packets, 10 ml each — one per leg.

Is LactiGo vegan, and what else is not in it?

Yes, LactiGo is vegan: the brand says the raw materials for its L-carnosine are derived from corn. There is no caffeine, no stimulant, nothing to swallow, and nothing on the WADA Prohibited List — and every batch is Informed Sport tested.
