Typical: 5–15 g

A leaf extract from the ginkgo tree standardized to flavone glycosides and terpene lactones, long used in memory and circulation formulas.

Typical: 120–240 mg

A conditionally essential amino acid that serves as the direct precursor to dopamine, norepinephrine, and epinephrine.

Typical: 200–400 mg

An acetylated form of carnitine that crosses the blood-brain barrier more readily than carnitine itself and donates acetyl groups for acetylcholine synthesis.

Typical: 500–2,000 mg

A branded water-extracted ashwagandha made from both leaf and root and standardized to a minimum of 10% withanolide glycosides, which lets it work at a smaller dose than root-only extracts.

Typical: 125–250 mg

Guarana is the seed of Paullinia cupana, an Amazonian vine whose seeds contain more caffeine by weight than coffee beans, along with theobromine and tannins.

An extract of a creeping wetland herb from traditional Indian practice, standardized to bacosides, that is one of the better-studied botanical nootropics for memory.

Typical: 300–450 mg

A magnesium salt of L-threonic acid, a vitamin C metabolite, developed at MIT as a form that raises brain magnesium in animal models.

Typical: 100–144 mg

MCT oil powder is MCT oil spray-dried onto a carbohydrate carrier, most often acacia gum or maltodextrin, to produce a free-flowing powder that disperses in water.

Typical: 5–10 g

Phosphatidylserine is a phospholipid concentrated in neuronal membranes where it supports receptor function, neurotransmitter release, and signaling.

Typical: 100–300 mg

A leaf extract of lemon balm, a mint-family herb with a citrus aroma, used in calming, sleep, and focus formulas.

Typical: 300–600 mg

Huperzine A is an alkaloid from the club moss Huperzia serrata that reversibly inhibits acetylcholinesterase, raising acetylcholine levels in the brain.

Typical: 50–200 mcg

Nitrosigine is a patented complex of L-arginine bound with silicate and stabilized by inositol, developed by Nutrition21.

Typical: 1,500 mg

An acetylated form of tyrosine marketed for better water solubility than plain L-tyrosine, which makes it convenient in ready-to-drink and powder formulas.

Typical: 350–1,000 mg

Theacrine is a purine alkaloid structurally related to caffeine, found in kucha tea and cupuaçu.

Typical: 50–200 mg

Alpha-GPC is a water-soluble phospholipid metabolite that delivers choline across the blood-brain barrier more efficiently than choline salts, which is why it anchors many focus and memory formulas and pre-workout blends.

Typical: 300–600 mg

The root of a ginseng species native to North America, used in focus and calm-energy formulas.

Typical: 200–400 mg

Citicoline is a naturally occurring nucleotide that splits in the gut into choline and cytidine (converted to uridine), giving the brain both a choline source for acetylcholine and phosphatidylcholine and a uridine source for membrane synthesis.

Typical: 250–500 mg

Yerba mate is the leaf of Ilex paraguariensis, brewed as a tea across South America.

Typical: 500–1,500 mg

A metabolite of arginine that acts as a neuromodulator, binding imidazoline and NMDA receptors and influencing nitric-oxide synthase.

A seed extract of velvet bean standardized to L-DOPA, the direct precursor of dopamine, used in mood, motivation, and men's vitality formulas.

Typical: 250–500 mg
