Relaxation support, stress support, sleep support
Adults with busy, high-stress evenings or those seeking a wind-down routine before bed.
Take 2 to 4 tablets 30 to 60 minutes before bedtime; consider starting at the lower amount to assess comfort, and take with a small snack if sensitive.
Contains no dairy, egg, gluten, soy or wheat. Contains no sugar, preservatives, or artificial colour, flavour or fragrance.
Magnesium acts as a cofactor for enzymes involved in nerve signalling and muscle relaxation and helps regulate the GABA and melatonin systems associated with calmness and sleep readiness.
Caution: High intakes may cause loose stools; take with food if sensitive and separate from certain medications because minerals can affect absorption.
GABA is an inhibitory neurotransmitter that may help calm neuronal activity, promoting relaxation and a sense of ease before bedtime.
Caution: May cause drowsiness; avoid activities requiring alertness after taking and consider starting with a lower amount to assess response.
Taurine modulates GABA and glycine receptors and supports membrane stability, which may help ease excitability and promote relaxation.
Caution: May enhance sedative effects when combined with other calming ingredients; use at night as directed to gauge personal sensitivity.
Valerian contains valerenic compounds that may interact with GABA pathways and adenosine signalling to encourage calm and reduce restlessness.
Caution: Can cause daytime drowsiness in some people; avoid alcohol and take in the evening to see how you respond.
Passionflower flavonoids are thought to influence GABA activity, which may help settle a busy mind and ease tension before sleep.
Caution: May increase drowsiness when used with other calming agents; take before bedtime and avoid driving afterwards.
Magnesium and taurine help modulate nerve excitability and support GABAergic tone, creating a foundation for relaxation. GABA offers direct inhibitory signalling, while valerian and passionflower add botanical compounds that influence GABA and adenosine pathways for a broader calming effect.
Label Warning: If you are pregnant, may become pregnant, or breastfeeding, consult a healthcare professional before use. California Proposition 65 warning for reproductive harm.
Who should be cautious: People taking thyroid medications or certain antibiotics may need to separate calcium and magnesium by at least 2 hours. Those sensitive to sedatives or using sleep aids should be cautious due to valerian, passionflower, skullcap, chamomile, GABA and taurine, which may cause drowsiness. If using medications that may interact with calcium or magnesium, discuss with a healthcare provider before use.
