Ingredient research · Vitamin B6

Vitamin B6 is an essential nutrient that helps enzymes process amino acids and supports neurotransmitter, hemoglobin, and immune function. Supplementation reliably corrects deficiency and can reduce nausea during pregnancy; outside these uses, it is most relevant when intake or absorption is inadequate.

• Supports depressive-symptom measures in premenopausal women with hormone-related contexts.

Ingredient research · 5-HTP

5-HTP is an amino acid derivative the body uses to make serotonin and, downstream, melatonin. It is commonly taken for mood and sleep, with possible but inconsistent benefits; because it raises serotonin, it can interact importantly with antidepressants and other serotonergic drugs.

• Supports levodopa-induced motor-complication measures in Parkinson's disease.

Ingredient research · L-Tyrosine

L-Tyrosine is an amino acid the body uses to make dopamine, norepinephrine, and thyroid hormones. Supplementation may help preserve attention, working memory, and mental performance during acute stressors such as sleep loss or cold exposure, but it is not a reliably effective everyday cognitive or mood enhancer.

• Supports cycling endurance during exercise in the heat.

Ingredient research · GABA

GABA is the brain’s main inhibitory signaling molecule, helping dampen neural activity, and supplemental GABA is commonly taken to promote relaxation, ease stress, or support sleep. However, it is unclear how much orally consumed GABA reaches the brain, and human benefits appear modest and inconsistent.

Ingredient research · L-Theanine

L-Theanine is an amino acid found naturally in tea that can promote a calmer mental state without causing marked drowsiness. As a supplement, it may ease perceived stress, support sleep quality, and improve attention when paired with caffeine, although cognitive effects on its own are less consistent.

• Supports selected stress and anxiety-related measures.
