L-tryptophan is converted into 5-HTP and then serotonin and melatonin, which may influence mood, relaxation and sleep-wake signalling.
Caution: May cause drowsiness; avoid before driving and separate from protein as other amino acids can compete for absorption.
Niacinamide acts as a precursor for NAD+, supporting cellular energy reactions involved in neurotransmitter metabolism.
Caution: High doses may cause flushing or digestive discomfort in some people; take with food if sensitive.
L-lysine is an essential amino acid that may influence neurotransmitter activity and stress-related signalling pathways.
Caution: Amino acids taken with protein-heavy meals may compete for uptake; separate timing if aiming for specific effects.
Hops extracts contain bitter acids that may promote relaxation by modulating GABA-related signalling.
Caution: May increase drowsiness; avoid combining with sedative substances and alcohol.
Rosemary polyphenols may offer antioxidant activity and mild calming effects by interacting with neuronal signalling and oxidative stress pathways.
Caution: Concentrated extracts may cause digestive upset in some individuals; take with food if sensitive.
L-tryptophan supplies substrate for serotonin and melatonin production, while niacinamide supports NAD+-dependent enzymes involved in tryptophan metabolism. Hops extract adds calming GABA-related activity, and rosemary contributes antioxidant support and gentle relaxation. L-lysine complements the formula by influencing stress-related neurotransmission.
Label Warning: Consult a healthcare provider before use if taking mood-related medication such as MAOIs or SSRIs. Use caution before driving or operating heavy machinery. Do not exceed the recommended dose. Consult a doctor if you have a medical condition or if pregnant or breastfeeding.
Who should be cautious: People using antidepressants or mood medications. Those sensitive to sedatives or with sleep disorders may wish to start with a lower dose. If combining with serotonergic medications, speak with a healthcare provider first to reduce serotonin syndrome risk.
Storage: Store tightly closed in a cool, dry place.
