Magnesium is an essential mineral involved in hundreds of biochemical reactions in the body. From supporting muscle and nerve function to regulating blood sugar levels and promoting bone health, magnesium plays a vital role in keeping us feeling well. When it comes to supplements, two forms are particularly popular in the UK and Ireland: magnesium glycinate (also known as bisglycinate) and magnesium citrate. Both are highly bioavailable, but they differ in composition, absorption, and how they benefit the body.
Magnesium Glycinate (Bisglycinate)
Magnesium glycinate combines magnesium with glycine, a calming amino acid. As a chelated form of magnesium (meaning it's bound to an amino acid), it’s gentle on the stomach and easily absorbed by the body.
Key benefits of magnesium glycinate include:
-
Superior Absorption: Chelated minerals like magnesium glycinate are better recognised and utilised by the body, ensuring effective magnesium delivery.
-
Calming Properties: Glycine supports the nervous system and may help reduce stress and promote deeper, more restful sleep.
-
Muscle Support: This form is known to ease muscle tension, making it a favourite among those with cramps or tightness.
Magnesium Citrate
Magnesium citrate is formed by combining magnesium with citric acid, a naturally occurring compound found in citrus fruits. It’s one of the most widely used magnesium forms due to its versatility and digestive benefits.
Top reasons people choose magnesium citrate:
-
Bioavailable and Effective: Citrate is a well-absorbed form that helps maintain optimal magnesium levels.
-
Digestive Relief: Thanks to its mild laxative effect, magnesium citrate is often recommended for occasional constipation.
-
Energy Metabolism: Magnesium plays a critical role in ATP (adenosine triphosphate) production, which fuels our body’s energy systems.
Why MAG365 is Different: Ionic Magnesium Citrate for Optimal Absorption
MAG365 is not your average magnesium citrate supplement. It’s an ionic magnesium powder that becomes highly absorbable once activated in water. This “pre-digested” format allows your body to absorb the magnesium quickly and efficiently—without relying on the digestive system to break it down. For individuals looking to increase their magnesium levels swiftly and effectively, MAG365 is a smart and convenient solution.

Which Magnesium is Right for You?
-
If you're looking for digestive support, enhanced energy, or a fast-acting format, magnesium citrate (especially in its ionic form like MAG365) may be the better fit.
-
If you need something that’s calming, gentle on the stomach, and effective for muscle relaxation, magnesium glycinate (bisglycinate) is likely your best option.
Whichever you choose, both forms offer unique benefits that can help you maintain balanced magnesium levels and support overall wellbeing.
