Sleep, Mood & Brain
Groups melatonin, amino-acid and inositol compounds, calming or stimulating combinations, and NAD-related nutrients acting through circadian, neurotransmitter, second-messenger, or cellular-energy pathways.
Narrow by ingredient, form, or use.
Each group keeps closely related formulations together so strengths and forms are easier to compare.

5-HTP & Inositol
5-HTP is a serotonin precursor, while myo-inositol and D-chiro-inositol participate in cellular second-messenger systems; their neurological and metabolic uses are biologically distinct.

9 products
Apigenin & Sleep Blends
Apigenin is a plant flavone, while magnesium and tryptophan sleep combinations join nutrients involved in neuromuscular function or serotonin synthesis; evidence depends on each composition.

12 products
L-Theanine & GABA
L-theanine, GABA, theanine-caffeine combinations, and theanine-GABA blends target relaxation, inhibitory neurotransmission, or focused alertness; caffeine-containing options have a distinctly stimulating profile.

Melatonin Supplements
Standard and extended-release melatonin provide the hormone that signals biological night and regulates circadian timing; extended release prolongs exposure compared with conventional forms.

9 products
NAD & Cellular Support
NADH participates directly in cellular redox and energy reactions, nicotinamide riboside is an NAD precursor, and PQQ is redox-active; supplemental outcomes remain under active investigation.
