What is ITL Health PrizMAG and what does it do?
Each capsule provides 800mg of magnesium bisglycinate (95mg elemental magnesium bound to 705mg glycine), combining two nutrients studied for supporting calm, uninterrupted sleep. Unlike some sleep products, it's not intended to cause morning grogginess or dependency, and is formulated to be gentle on digestion.
What does research say about magnesium and glycine for sleep?
A randomized, placebo-controlled trial using 250mg of elemental magnesium as bisglycinate over 4 weeks found improvements in self-reported sleep quality in adults with poor sleep. Glycine on its own has shown some evidence at doses around 3g for improving sleep quality and reducing daytime fatigue, working partly through interaction with NMDA receptors, though larger studies are still needed to firmly establish optimal dosing for the combination.
How should this be taken?
Adults should take one capsule daily, increasing up to 4 capsules as needed, or as directed by a healthcare practitioner, since individual needs vary. It can be taken with or without food.
How does this differ from other magnesium bisglycinate products on the market?
Many magnesium bisglycinate products blend in magnesium oxide to reduce cost, since oxide is cheaper per milligram of elemental magnesium, and typically include fillers or magnesium stearate as processing aids. This product uses 100% pure magnesium bisglycinate with no added magnesium oxide, fillers, or stearates, positioning it for people who specifically want to avoid oxide dilution or find stearates cause digestive sensitivity.
What is ITL Health and what is the brand known for?
ITL Health is a magnesium supplement brand headquartered in Sarnia, Ontario, Canada. Originally founded in the UK and Ireland by philanthropist George Esser, the company is now run by his daughters and has established its Canadian base in Ontario. ITL Health is best known for two magnesium products: MAG365, an ionic magnesium citrate powder that activates when dissolved in water, and PrizMAG, a pure magnesium bisglycinate capsule. Both are licensed by Health Canada and manufactured in compliance with GMP standards. The brand also offers a Vitamin D Plus formula combining vitamin D3 (from lichen), methylcobalamin B12, K2, and magnesium bisglycinate.
How does ITL Health differ from other magnesium supplement brands?
ITL Health's primary differentiator is its MAG365 format: an ionic magnesium citrate powder that is dissolved in hot water before consumption. When citric acid and magnesium carbonate react in water, they form magnesium citrate in an ionic, highly soluble state — a different delivery mechanism from pre-formed magnesium citrate capsules. The resulting drink form is gentle on digestion and does not require stomach acid to break down, which can be an advantage for users with compromised gastric function. PrizMAG uses pure magnesium bisglycinate with no fillers or added magnesium oxide, a distinction from many bisglycinate products that blend in oxide to reduce cost. The brand's dual-country heritage (UK/Ireland + Canada) has given it a broader clinical following than most Canadian-only magnesium brands.
