You might have come across various forms of magnesium:

  • glycinate
  • citrate
  • malate
  • threonate
  • oxide
  • chloride

How to know which one is right for you?

I will try to explain it in today’s post.

Before that, here are some of the symptoms of low magnesium:

  • Muscle pain, cramps, and spasms from feet cramps to chest pain (due to spasms in your heart muscle), and even restless leg syndrome
  • Headaches and migraines
  • Feeling constantly fatigued or weak
  • Depression, anxiety, and edginess
  • Craving chocolate (cacao is high in magnesium)
  • Quick exhaustion during exercise
  • Insomnia and mid-night waking

Magnesium and hormones 

Let’s not forget that magnesium also plays a huge role in hormonal balance.


1. Improves the thyroid function

2. Supports estrogen detoxification of harmful metabolites

3. Lowers blood sugar levels

4. Lowers adrenalin and cortisol

5. Supports testosterone production

6. Increases serotonin

7. Increases DHEA

Which form of magnesium is right for you? 


Not all supplements are made the same and magnesium is no different. Here is a low-down to help you understand each form of magnesium:

Recommended Forms

My 1st choice: Magnesium Bisglycinate

Also known as magnesium chelate, magnesium diglycinate, magnesium glycinate.  It is a highly absorbable form of magnesium chelated to two molecules of the amino acid glycine.

This is the form of magnesium I take every day. I would double up to 600mg, or even 800mg per day if I’m stressed, or when I’m traveling (also a form of stress).

“Chelated” forms of a mineral mean that an amino acid has been attached to them making them a very stable form of magnesium that is less likely to cause gastrointestinal symptoms and reduces the laxative effect.

Yet, it helps with PMS, fibrocystic breasts, sleep, anxiety, cravings, pains, and cramps.

The brand I use and recommendMagnesium Replenish

Magnesium citrate

Another chelated type of magnesium bound to citric acid. This form of magnesium is about 30% bioavailable, but it pulls water into the bowels giving it more of a laxative effect, which some may like if suffering from chronic constipation.  For a deeper dive into constipation, check out this article.

This is a good form for you If you feel depleted in magnesium (based on the symptoms) and struggle with chronic constipation.  Whenever I travel, I bring along a bottle of citrate to keep things moving.  

The brand I use and recommendMagnesiumCitrate

Magnesium malate

Another type of magnesium bound to malic acid. For those having issues with energy production, a magnesium malate supplement may be effective for helping with chronic fatigue syndrome and/or fibromyalgia.

No surprise, this form may be too stimulating for some and may disrupt sleep, especially when taken at night (I had this experience first hand!).

The brand I recommend:  Magnesium Malate.

Magnesium threonate

 Threonate is a form of magnesium chelated to threonic acid, a metabolite of vitamin C.

This form of magnesium in comparison to others was created to cross the blood-brain barrier – it may, therefore, improve learning and memory functions and maybe be especially beneficial for age-related cognitive decline.  The suggested dose is 2,000 mg of magnesium threonate.

The brand I recommend: Pure Encapsulations.

Magnesium chloride

Good for external use. 

Chloride is a form of magnesium for topical use. The skin is a great way to increase magnesium levels and bypass using the gut – this is especially beneficial for people with IBS (or leaky gut) who suffer from malabsorption of nutrients.

The brand I recommend: Quick Magnesium. It is a pure, 100% natural solution of magnesium chloride, coming from high-quality magnesium salt derived from the depths of the earth’s interior – all from the ancient Zechstein Seabed in Europe. Ultra-pure and untouched by pollutants, this magnesium salt was protected at depths of 5,000-6,500 feet in this seabed for the past 250 million years.

Many of our program participants have reported fantastic results using this form of magnesium; from pain reduction, feeling calmer, to deeper/longer sleep.

Magnesium sulphate

Good for external use. 

Epson salts are in this form. Great for external use (such as baths). Internal use can cause severe diarrhea. People with certain genetic variance don’t tolerate this form of magnesium very well.  

See video below for more discussion on these forms of magnesium:

Not Recommended

Magnesium oxide 

Oxide contains a lot of magnesium by weight but has a bioavailability of only 4%. This form is found in many magnesium supplements and should be avoided.  Therefore, I have no brands to recommend here. I’ve also found that many MLM (multi-level marketing companies) use this form of magnesium in their product line-ups.

Magnesium stearate

Used as a coating agent in supplements, not soluble in water, therefore should be avoided.

Magnesium oxide

Only has 4% bioavailability and can cause negative reactions. Companies that use it tend to add other low-quality ingredients. I do not recommend using it at all.

Magnesium lactate

It is derived from lactic acid which is milk. I recommend avoiding dairy in any form.

Magnesium aspartate

Studies show that it does not dissolve well in water, its bioavailability is therefore low.
