Pharmacological Action

Glycine is an amino acid. In the central nervous system (CNS) glycine acts as an agonist at the glutamate receptor N-methyl-D-aspartate (NMDA). The concentration of glycine in the brain is fairly stable due to the dietary consumption of glycine. However, the addition of supplements can increase CNS concentrations of glycine. Theanine is thought to work for stress-induced anxiety by reducing the release of glutamate, an excitatory neurotransmitter. It is also used for its relaxing and anti-anxiety effects.

Magnesium helps relax muscles and is believed to block the release of excess excitatory neurotransmitters in the brain. Magnesium is also used orally for treating attention deficit hyperactivity disorder (ADHD), anxiety and chronic fatigue syndrome (CFS).

Dosage Directions

Dissolve 1 sachet into approximately 100 ml water before bed. Consume within 24-hours of mixing.

Do not use this product if you are hypersensitive (allergic) to any of the ingredients. If you are on any medication or suffering from any medical condition, it is advisable to seek medical advice before starting any new medicine, supplement or remedy. Do not exceed recommended dosages unless on the advice of a healthcare practitioner. This medicine has not been evaluated by the Medicines Control Council. This medicine is not intended to diagnose, treat, cure or prevent any disease.

Do not use continually for more than 3 months without consulting your healthcare practitioner.

Side Effects

Side effects may include nausea, vomiting, diarrhoea, upper gastrointestinal tract discomfort and drowsiness.


There are no known contraindications.


Antihypertensive medicines: Theoretically, concomitant use of Theanine might potentiate the activity of antihypertensive medications.
Calcium channel blockers: Magnesium inhibits calcium entry into smooth muscle cells and may therefore have additive effects with calcium channel blockers.
Potassium sparing diuretics: They also have magnesium sparing properties, which can counteract the magnesium losses associated with loop and thiazide diuretics.
Quinolone antibiotics: Magnesium can decrease quinolone absorption. Individuals should take magnesium at least 2 hours before, or 4 to 6 hours after quinolone antibiotics.

Pregnancy and Breastfeeding

Safety during pregnancy and whilst breastfeeding has not been established.
