A familiar evening ingredient, precisely dosed in milligrams.

Aerial-parts extract of passionflower (Passiflora incarnata), a plant long used in calming preparations. It's a mainstay of evening and wind-down blends, with no caffeine or stimulants.

Root extract of Valeriana officinalis, traditionally used to support relaxation and restful sleep. Its distinctly earthy, pungent aroma makes capsules the format most people prefer.

The seed of Ziziphus jujuba — suan zao ren in traditional Chinese herbal practice — naturally supplies saponins known as jujubosides. A time-honored choice for evening wind-down blends.

One of the most-researched ingredients in sports nutrition, used to support training performance.

A racemic blend of the D- and L-forms of methionine, a sulfur-containing essential amino acid. Traditionally grouped with the lipotropic factors; carries the faint sulfur note typical of this amino acid.

Combines both mirror-image forms of phenylalanine: the L-isomer, an essential amino acid and tyrosine precursor, and the D-isomer. A longtime pick for mood- and focus-oriented stacks.

A blend of all nine amino acids the body cannot make on its own, supplied in free form. A staple of training and recovery stacks, its gram-scale servings suit powders far better than capsules.

A free-form, glucogenic nonessential amino acid, L-alanine is a faintly sweet, readily water-soluble powder often folded into amino acid and endurance formulations.

Free-form L-arginine is a conditionally essential amino acid and the body's direct precursor to nitric oxide, making it a mainstay of circulation- and pump-focused stacks.

The hydrochloride salt of L-arginine, this form dissolves more readily and tastes slightly tart; like base arginine it feeds the nitric oxide pathway and suits pre-workout blends.

This pairs L-arginine with L-pyroglutamate in one free-form powder, a nitric-oxide-precursor amino acid combination often chosen for nootropic and circulation stacks.

A free-form acidic amino acid with a distinctly sour note, L-aspartic acid takes part in the urea cycle and energy metabolism and appears in many amino acid formulations.

Built in the body from lysine and methionine, free-form L-carnitine shuttles fatty acids into the mitochondria and is a familiar component of energy- and endurance-oriented blends.

The hydrochloride salt of the sulfur-bearing amino acid cysteine, this readily soluble powder carries a pronounced sulfur odor and serves as a precursor in the glutathione pathway.

L-cystine is two cysteine molecules linked by a disulfide bond, a poorly water-soluble amino acid form that acts as a stable cysteine reservoir in the body.

A free-form acidic amino acid with a savory, umami taste, L-glutamic acid is a building block of protein and a common addition to amino acid formulations.

The hydrochloride salt of glutamic acid, this form is more soluble and noticeably tart-acidic, offering the same free-form amino acid in a readily dissolving powder.

Free-form L-histidine is an essential amino acid and the precursor the body uses to make carnosine and histamine, and it's a routine inclusion in amino acid blends.

The hydrochloride salt of L-histidine, this form dissolves more easily and stays stable as a powder, delivering the same essential amino acid used to build carnosine.

One of the three branched-chain amino acids, free-form L-isoleucine is a slightly bitter, essential amino acid that's a standard part of BCAA and intra-workout formulations.

The most abundant of the three branched-chain amino acids (BCAAs), offered as a free-form powder and a mainstay of recovery and intra-workout formulas; it has a characteristically bitter taste.

An essential amino acid supplied as its stable hydrochloride salt, free-form and readily water-soluble, it is a routine addition to protein-support and collagen-focused formulas.

A sulfur-containing essential amino acid and a key methyl donor, offered free-form; it acts as a precursor to cysteine and is a common addition to methylation-support formulas.

A bonded pairing of the amino acid ornithine with alpha-ketoglutarate, supplied as a single-ingredient powder and traditionally used in athletic recovery and post-exercise support formulas.

This salt links ornithine to aspartate, two amino acids tied to the urea cycle, and comes as a free-form powder found in recovery and ammonia-metabolism support stacks.

An essential aromatic amino acid and the metabolic precursor to tyrosine and the catecholamines, offered free-form and common in mood- and focus-oriented stacks; not suitable for those with PKU.

A non-essential amino acid that, alongside glycine and lysine, forms the backbone of collagen. This free-form powder is a staple of skin, joint, and connective-tissue formulas.

A non-essential amino acid the body uses to build phospholipids and neurotransmitters, supplied free-form and a frequent component of cognitive- and sleep-support formulas.

An essential amino acid and a building block of collagen, elastin, and gut-lining mucins, this free-form powder is commonly added to structural-protein and gut-support formulas.
