Magnesium Glycinate

Magnesium glycinate is magnesium bound to the amino acid glycine. It is widely regarded as one of the gentlest, best-absorbed forms of magnesium, which is why it is the form many people reach for when they want a daily magnesium that is easy on the stomach. It is also the form most associated with evening routines, as magnesium plays a role in normal nervous-system function and supports sleep quality. Free shipping on orders over $150 AUD.

What is magnesium glycinate?

Magnesium glycinate is a chelate: a magnesium ion bound to two molecules of the amino acid glycine. You will see it sold under two names that mean the same thing - "magnesium glycinate" and "magnesium bisglycinate". The "bis" simply refers to the two glycine molecules attached to each magnesium. If a label says bisglycinate, you are buying glycinate. Some products list "magnesium bisglycinate" to be precise; others shorten it to glycinate. Both are the same chelated form.

Magnesium itself is an essential mineral involved in hundreds of processes in the body, from energy production to normal muscle and nervous-system function. The catch is that magnesium on its own is not well absorbed - the form it is bound to matters a great deal. That binding partner (the glycine, the citrate, the oxide) changes how gentle the supplement is and how much your body takes up. Glycinate's binding partner, glycine, is itself a calming amino acid involved in normal nervous-system function, which is part of why this particular form has become the go-to for daily, everyday use.

Why glycinate is the gentle, well-absorbed form

Two things make magnesium glycinate stand out from cheaper forms like magnesium oxide.

It is well absorbed. Chelated forms of magnesium, glycinate among them, are generally absorbed more efficiently than inorganic salts such as oxide. That means more of what is on the label is actually taken up rather than passing through. Source: National Institutes of Health Office of Dietary Supplements, Magnesium Fact Sheet.

It is gentle on the digestive system. The forms of magnesium that draw water into the digestive tract - oxide, and to a lesser extent citrate at higher doses - are more likely to cause loose stools. Glycinate is far less likely to do this, which is why it is the form usually recommended for people who want a daily magnesium they can take consistently without digestive upset. If you have tried magnesium before and found it disagreed with you, glycinate is the form worth trying next.

The combination - well absorbed, easy on the gut - is exactly why glycinate commands the most search interest of any magnesium form in Australia, and why it is the form most often suggested for taking every day over the long term.

Magnesium glycinate and sleep

The single biggest reason people search for magnesium glycinate is the evening, wind-down routine. Magnesium plays a role in normal nervous-system function, and the glycine it is bound to is an amino acid associated with calm. Together, that is why glycinate is the form most commonly chosen by people building a nightly routine, and why magnesium is widely discussed as a supplement that may support sleep quality as part of a healthy lifestyle.

A note on what we are and are not saying: magnesium is not a sleeping tablet and is not a treatment for insomnia or any sleep disorder. What the everyday-wellbeing evidence supports is that magnesium contributes to normal nervous-system function and that maintaining adequate magnesium intake supports overall sleep quality. If you have an ongoing sleep problem, that is a conversation for your GP, not a supplement decision. For the full picture, see our guide to magnesium for sleep, which covers which form people choose and when to take it.

Glycinate vs other forms of magnesium

There are many forms of magnesium on the Australian market, and they are not interchangeable. Here is how glycinate compares to the forms you will see most often.

Glycinate vs citrate. Citrate is also well absorbed, but it is more noticeable on digestion at higher doses because it draws water into the digestive tract. Glycinate is the gentler of the two and the better pick if your goal is a daily magnesium for evening routines or general wellbeing. Citrate suits people who want a well-absorbed everyday form. Read the full comparison: magnesium glycinate vs citrate.

Glycinate vs oxide. Magnesium oxide is the cheapest form and has a high amount of magnesium by weight, but it is poorly absorbed and the most likely to cause loose stools. Glycinate is far better absorbed and far gentler. If you are comparing on price alone, oxide looks attractive; on absorption and tolerability, glycinate wins comfortably.

Glycinate vs threonate. Magnesium L-threonate is the form most associated with cognitive-focused routines because of how it is studied for the brain. Glycinate is the all-rounder for daily use and evening routines. Many people who want both end up taking glycinate daily and threonate for focus. See our magnesium threonate range.

Glycinate vs blends. Magnesium complex products combine several forms - often glycinate, citrate and others - to cover more bases in one serve. If you want glycinate plus the benefits of other forms in a single product, a magnesium complex is the practical choice. For a full breakdown of every form, see types of magnesium.

Who magnesium glycinate suits

Glycinate is the sensible default for most healthy adults who want a daily magnesium. It particularly suits:

  • Anyone building an evening or wind-down routine. The form most chosen for nightly use.
  • People with a sensitive stomach. If oxide or citrate has caused loose stools, glycinate is the gentle alternative.
  • Daily, long-term users. Well absorbed and easy to tolerate, so it is easy to take consistently.
  • People who want a single, clean form rather than a blend - though a blend is a fine choice too if you want broader coverage.

If your priority is cognitive focus, look at threonate. If you want broad coverage from one product, look at a complex. If you simply want the gentle, well-absorbed everyday form, glycinate is your answer.

How to take magnesium glycinate

Dose. Follow the label on your chosen product. As a guide, the Australian recommended dietary intake for magnesium for adults is set by the NHMRC, and supplements are designed to top up dietary intake, not replace food. Magnesium-rich foods (leafy greens, nuts, seeds, wholegrains, legumes) do a lot of the work - see foods high in magnesium.

Timing. Because glycinate is the form most associated with evening routines, many people take it with their evening meal. There is no strict rule - the most important thing is taking it consistently. See when to take magnesium for the morning-versus-night breakdown.

With or without food. Either works. Taking it with food can make it gentler if you have a sensitive stomach.

FAQ

What is magnesium glycinate best for?

Magnesium glycinate is best for people who want a gentle, well-absorbed daily magnesium - especially those building an evening or wind-down routine, and those with a sensitive stomach who have not tolerated other forms. Magnesium plays a role in normal nervous-system and muscle function and supports sleep quality as part of a healthy lifestyle. It is the most common all-round daily choice.

What is the downside of magnesium glycinate?

The main downside is cost: glycinate is more expensive per serve than basic forms like magnesium oxide, because the chelated form is better absorbed and gentler. It is also a larger molecule, so capsules can be bigger or you may need more of them to reach a given dose. For most people the gentleness and absorption are worth the trade-off, but on price alone, cheaper forms exist.

What happens if you take magnesium glycinate every day?

For most healthy adults, taking magnesium glycinate daily at the dose on the label is well tolerated, and daily use is how magnesium supplements are designed to be taken. Magnesium is a mineral your body uses continually. If you take more than your body needs, the excess is generally passed in urine. If you have kidney problems or take regular medication, talk to your GP before daily use.

What to avoid when taking magnesium glycinate?

Avoid taking it at the exact same time as certain medications that bind to minerals - some antibiotics and thyroid medicines are absorbed less well when taken alongside magnesium, so space them apart. Avoid exceeding the dose on the label, as very high intakes from supplements can cause loose stools even with gentle forms. If you take prescription medication or have a health condition, check timing and suitability with your pharmacist or GP.

What are the 7 signs your body needs magnesium?

Commonly discussed signs of low magnesium include tiredness or low energy, muscle twitches or cramps, poor sleep quality, low mood, headaches, an irregular heartbeat sensation, and reduced appetite. These signs are non-specific and can have many causes, so they are not a diagnosis. If you are concerned about your magnesium levels, see your GP, who can test and advise. For more, see signs of magnesium deficiency.

Is magnesium glycinate the same as bisglycinate?

Yes. "Magnesium glycinate" and "magnesium bisglycinate" refer to the same chelated form - magnesium bound to the amino acid glycine. The "bis" indicates the two glycine molecules attached to each magnesium ion. Manufacturers use either name, so if a label says bisglycinate, you are buying glycinate.
