The 5 Best Magnesium Supplements in 2023

Supplementing magnesium is one of the easiest wins you can have in your health journey. 

Not only is it relatively affordable, accessible and usually comes in forms that taste great – it can make you feel like a million bucks when you wake up after a hard workout.

30% of adults are estimated to be deficient in magnesium – so this is one of the areas where supplementing the item makes absolute perfect sense.

What Is Magnesium?

Magnesium is a naturally occurring mineral.

It’s very common on red meat, fish, some fruits and seeds. 

That said – due to the processed nature of most people’s diets – a huge chunk of the population is deficient in this super important mineral.

Magnesium is incredibly helpful for athletes and other high performance humans when it comes to sleep, recovery and muscle growth.

What’s the Recommended Dose of Magnesium?

The recommended daily dose of magnesium is 200-400mg/day. Make sure whatever supplement you choose has an efficacious dose.

Types of Magnesium

There’s several forms of magnesium. The type magnesium you take will range the bioavailability, and effective dosage. Some of the most

The Most Common Magnesium Forms

Magnesium Citrate

One of the most common forms of magnesium, magnesium citrate is both bioavailable and soluble in liquid. This makes for easy mixing for drinks and is one of our favorite ways to take magnesium.

Magnesium Gluconate

Considered by some to be the most bioavailable form of magnesium – gluconate is not as 

Magnesium Oxalate

Lower bioavailability. While it contains more elemental magnesium – it is often difficult for the body to absorb and is used more often for a laxative.

Magnesium Dihydroxide

Again, not used nutritionally, but for laxative purposes.

Other forms of magnesium:

Magnesium Glycinate

There’s a form of magnesium glycinate that is becoming more popular called “magnesium bisglycinate” – this is the same compound but with two glycine molecules. It’s a patented version of this compound and tough to source as of the 2020-2022 supply chain concerns.

Magnesium Sulfate

Magnesium Chloride

Magnesium Threonate

Magnesium Threonate has become popular from Dr. Andrew Huberman’s love of the compound. It’s ability to cross the blood-brain barrier is indeed interesting, but it’s a relatively new compound and there needs to be more studies to see just how much more effective this form is than others (but we think all forms of magnesium are awesome either way). Impossible has a great breakdown on l-threonate here.

Benefits of Magnesium

Some of the proven benefits of magnesium include:

  • Significant decrease in blood pressure
  • Reduction in asthmatic symptoms
  • Moderate regular of insulin and increase in insulin sensitivity
  • Imppovement in aerobic exercise + muscle oxygenation
  • Decrease in migraine symptoms
  • Decrease in PMS symptoms
  • Improvement in sleep quality
  • Slight reduce depressive symptoms
  • Slight increase in bone mineral density.

Magnesium is one of the easiest “no-brainer” supplements we recommend and most adults are woe-fully under-supplemented on this front.

A magnesium glycinate product from Thorne – they call it “bisglycinate” since there are two glycine molecules attached (two=bi).

Everything Thorne does Is solid and there’s no exception here – it’s even NSF Certified which is helpful if you’re an athlete. Sweetened with monk fruit – so if you’re not a fan of the flavor – that might be a deal breaker.

While the pills are cheaper, this is our preferred method of MagTech. That said, the lemonade flavor is not as good as the calm product. The quality is just as good though – so if you’re looking for another option – take a peek at this one.

Magnesium Breakthrough


Servings: 60 capsules (2/serving)

Magnesium per serving: 500mg

Type of Magnesium: Magnesium chelate, bisglycinate, oxide, malate, orotate, taurate, citrate

Form: Pill

image via Magnesium Breakthrough

Magnesium breakthrough’s claim to fame in that they contain all 7 forms of magnesium. Now, what they don’t tell you is what quantities they’re all in. It’s sold as a “blend” so in some ways that’s actually less helpful as different form of magnesium contain different elemental levels of magnesium and are differently absorbed by the body.

Overall, this seems to be high quality and the reviews are solid, but don’t buy totally into the 7-in-1-claims like they want you to :).
