Melatonin is a hormone that signals darkness to the brain and helps coordinate the sleep–wake cycle through action on melatonin receptors in the suprachiasmatic nucleus.
Caution: May cause drowsiness; take only at bedtime and avoid driving or alcohol close to use.
Vitamin B6 acts as a coenzyme in neurotransmitter synthesis, including pathways involved in converting tryptophan to serotonin and melatonin.
Caution: High intakes over time may cause nerve tingling; stay within suggested use.
Calcium participates in neuronal signalling and muscle function, and small amounts may contribute to normal cellular communication.
Caution: Take with water to aid swallowing; separate from certain medicines like some antibiotics as advised by a professional.
Melatonin provides the direct sleep–wake timing signal by acting on melatonin receptors. Vitamin B6 supports the enzymatic steps that create serotonin and melatonin from tryptophan. Calcium contributes to general cellular signalling, complementing neurotransmitter activity.
Label Warning: For adult use only at bedtime. Not intended for children, teenagers, pregnant or nursing women. Consult a doctor before use if taking any medications or if you have a medical condition. Stop use and speak to a doctor if adverse reactions occur. Do not use with alcohol, when driving, or operating machinery. May cause drowsiness. Limit use to two months with a one-week break.

There are few other supplements that are as consistently effective at supporting healthy, deep sleep as melatonin. In fact, Melatonin is an integral part of the body’s natural sleep cycle called the circadian rhythm, which controls not only the wake and sleep cycle, but other physiological functions such as blood pressure, digestion and brain-wave states as well. Melatonin is secreted by a small gland located at the base of the brain called the pineal gland, where it is produced by a conversion from serotonin. Serotonin itself is created by the conversion from the amino acid tryptophan, which is often deficient in the diet. The primary stress hormone, cortisol also inhibits melatonin production and absorption, leading to restless sleep and insomnia. Therefore, melatonin supplements are often recommended because they may help support deep, natural sleep and a consistent circadian rhythm cycle.
Adults - Take one tablet an hour before bedtime, as a dietary supplement. Do not exceed daily dose unless recommended by a healthcare professional.
