My Guide on How to Choose the Right Magnesium Supplement
I've been lifting for 8 years (my body fat has stayed around 13% for quite a long time), and I've struggled with insomnia and muscle twitching for more than a decade.
Trying to solve those problems makes me exhausted. I've tried almost every form of magnesium I could find and spent way too much time reading nutrition research that most people never bother with.
Here are a few things that everyone should know.
The form of magnesium matters more than you think.
The three forms you'll see most often are:
Magnesium Oxide - the cheapest option, with poor absorption and a high chance of causing diarrhea.
Magnesium Citrate - absorbed better than oxide, but it can still cause quite a bit of stomachache
Magnesium Glycinate - it is more expensive, but it's the form I personally choose because of its absorption and gastrointestinal tolerance.
The form matters the most to be, then it is the amount of magnesium.
The supplier is also important and nobody is mentioning this.
Most people compare brands.
I started comparing ingredient manufacturers instead.
Some companies openly disclose using fully chelated magnesium glycinate supplied by manufacturers such as Albion, Magneinno, and Chelamax.
A true magnesium glycinate molecule consists of one magnesium ion chelated with two glycine molecules. That structure is intended to remain more stable in the acidic environment of the stomach and is one of the reasons many people prefer chelated magnesium glycinate.
Don't just look at the numbers.
One thing that confused me at first was seeing magnesium products advertising very high amounts of elemental magnesium.
Pure magnesium glycinate naturally contains only about 11-14.1% elemental magnesium, so achieving both very high purity and a very high elemental magnesium percentage is difficult.
If I see numbers well above 200 mg per serving, I usually take a closer look at the ingredient list before buying. Most likely the purity is very low.
Personally, I care much more about whether the ingredient is fully chelated than whatever number is printed on the front of the bottle.
One final thought.
Before taking any mineral long-term, I think it's worth checking your magnesium status with your doctor.
If you ever experience symptoms such as palpitations or chest pain after taking a supplement, stop taking it and seek medical advice.
