Sleep support, relaxation, stress support
Adults with busy schedules seeking a calming nighttime routine or those with low evening wind-down time.
Take 1 to 2 tablets 30 to 60 minutes before bedtime; do not exceed the suggested use. Because melatonin and calming amino acids may cause drowsiness, use only at night and avoid alcohol; taking with a small snack can support tolerance.
Melatonin signals the body’s internal clock that it is nighttime, which may help regulate sleep-wake cycles.
Caution: May cause next-day drowsiness; avoid driving or alcohol close to use.
GABA is an inhibitory neurotransmitter that may calm neuronal activity and promote relaxation.
Caution: Can cause drowsiness; avoid combining with alcohol or other sedatives.
Magnesium acts as a cofactor for enzymes involved in nerve and muscle relaxation and supports GABA receptor function.
Caution: May loosen stools in some people; take with food if sensitive.
Glycine functions as an inhibitory neurotransmitter and may promote a calming effect before sleep.
Caution: May cause mild gastrointestinal discomfort in some individuals.
Taurine modulates GABA and glycine receptors and may support a relaxed nervous system state.
Caution: May cause mild sedation; use at bedtime as directed.
Melatonin helps set the body’s sleep timing, while GABA, glycine, and taurine act on inhibitory neurotransmission to encourage relaxation. Magnesium supports these processes by aiding nerve and muscle relaxation and supporting GABA activity.
Label Warning: Use only at bedtime. For adult use only. Not for children, teenagers, or women who are pregnant, may become pregnant, or breastfeeding. If under medical supervision, or have autoimmune disease, diabetes, depressive disorder, thyroid condition, epilepsy, leukemia, or a lymphoproliferative disorder, or are taking MAO inhibitors or corticosteroids such as hydrocortisone or prednisone, consult a physician before use. Do not use with alcohol. Do not use when operating machinery or driving.
Who should be cautious: People with sleep or mood medications, seizure history, thyroid issues, diabetes, autoimmune conditions, or hormone-related conditions may need caution. Those sensitive to sedatives or with planned lab tests should consider timing and discuss with a healthcare provider. Contains magnesium, which may reduce absorption of certain antibiotics and some medications if taken together; separate timing if applicable. If using medications that may interact with magnesium, consult a healthcare provider before use.
Storage: Store in a cool, dry place.
