MAGNESIUM GLYCINATE VS CITRATE: how to choose the right one for your body?

THEY’RE NOT THE SAME – AND THE DIFFERENCE MATTERS

Both magnesium glycinate and magnesium citrate are well-absorbed, widely recommended forms of magnesium. But in my years working as a physiotherapist and physical education teacher, I’ve seen firsthand how choosing the wrong form can leave people wondering why their supplement “isn’t working.” The mineral is the same — what changes is how your body uses it, and what it does once it gets there.

Magnesium Glycinate: Best for Calm, Sleep, and Recovery

Magnesium glycinate is magnesium bound to glycine, an amino acid with its own calming effect on the nervous system. This makes it the go-to form for:

– Poor sleep or difficulty switching off at night

– Anxiety or chronic stress

– Muscle tension and tightness

– Sensitive digestion

In clinical practice, this is the form I recommend most often for people who are mentally exhausted but physically wired — a pattern that’s far more common than most people realise.

Magnesium Citrate: Best for Energy, Cramps, and Daily Use

Magnesium citrate is magnesium bound to citric acid. It absorbs quickly, supports energy production, and has a mild relaxing effect on the intestinal muscles — making it particularly useful for people with sluggish digestion or constipation. It’s also the form I recommend first to active people and athletes dealing with muscle cramps or general fatigue.

– Low energy or persistent fatigue

– Muscle cramps during or after exercise

– Constipation or slow digestion

– General magnesium top-up

Quick Answer: Which One Is Right for You?

• Sleep, anxiety, tension –> MAGNESIUM GLYCINATE
• Energy, cramps, digestion –> MAGNESIUM CITRATE

Both –> Citrate by day + Glycinate at night
