Magnesium bisglycinate is magnesium bound to the amino acid glycine. GABA (gamma-aminobutyric acid) is made here by fermentation and sold under the PharmaGABA name, at 62.5 mg of PharmaGABA per capsule. L-theanine is an amino acid first found in tea leaves. Melatonin is the hormone the body releases in the evening as it gets dark; this one is made without animal sources.
The non-medicinal ingredients are carbohydrate gum, magnesium stearate, rice powder, silica, stearic acid and water. Natural Factors lists it as suitable for vegetarians and vegans, and non-GMO.
How to take it
Adults take 2 capsules once a day, at or before bedtime. For jet lag, take them at bedtime while travelling and at your destination until you have adjusted to the new time zone. Consult a health care practitioner for use beyond 4 weeks.
Do not use if you are pregnant or breastfeeding. When using this product avoid driving or using machinery for 5 hours. Avoid alcohol and other products that cause drowsiness. Ask a health care practitioner first if you take any prescription medication. The full directions and cautions are under How to Take.
How it compares
Most magnesium bedtime products pair the mineral with one other ingredient. This formula puts four in one capsule. CanPrev Magnesium + GABA & Melatonin Sleep (120 VCaps) skips the L-theanine. Natural Factors Stress-Relax Tranquil Sleep (90 Softgels) is the brand's other bedtime formula, without magnesium.
Who it suits
Adults who want magnesium and melatonin in the same bedtime dose, shift workers, and travellers crossing time zones eastward.
