The Ledger.
Every ingredient, every dose.

Most energy drinks run on bulk synthetic caffeine powder. TULUI uses Nuracaf, a branded natural caffeine, at a real 200mg dose per 12 fl oz can, roughly two cups of coffee in one clean pour. Same molecule your coffee makes, sourced on purpose, and disclosed to the milligram.

An amino acid found naturally in tea leaves. We pair it with the caffeine deliberately: research on caffeine and L-theanine taken together suggests a smoother, steadier experience than caffeine alone. Most cans skip it entirely. We consider it the other half of the formula.

A highly soluble form of the amino acid L-tyrosine, a building block the body uses to make several of its own neurotransmitters. 750mg is a real dose, printed on the label instead of buried in a blend.

An amino acid the sports-nutrition world knows well, studied for its role in the body's own nitric-oxide pathway. Two full grams per can. A true gram-level dose, the kind most cans only hint at.

A premium choline source. Choline is a nutrient the body uses to make acetylcholine and to build cell membranes, and Alpha GPC is one of the most studied ways to supplement it. Most energy drinks skip choline entirely. We dose it for real.

A nucleotide the body uses as a building block for cell membranes, brain cells included; that upkeep role is where the research on uridine points. Rare in this aisle, and ours carries a real 200mg dose.

B12 comes in two common forms. Most energy drinks use cyanocobalamin, the cheap synthetic form. TULUI uses methylcobalamin, the form your body uses directly. It costs more. We think it is worth saying so on the can.

A workhorse B vitamin involved in normal energy metabolism, dosed sensibly rather than at the four-digit "percent daily value" numbers some cans print for show.

Electrolytes that count: fine pink Himalayan salt and potassium, covering what sweat takes back. Enough to matter in a 12 oz can, not enough to taste like a sports drink.
