IMPORTANT: If you picked your magnesium by the biggest number on the front of the bottle, read this first. That number often describes magnesium glycinate, the whole compound. The number that matters, elemental magnesium, sits on the back, and it can be a fraction of the front.
You Bought Magnesium. Do You Know How Much Magnesium You're Getting?
Most people don't, and it isn't their fault.
You see “400 mg” in big type, you hold it next to a bottle that says “200 mg,” and the choice looks obvious.
Except those two numbers may not measure the same thing. One could be the compound. The other could be the magnesium itself.
Same aisle, same word on the label, and a very different amount of magnesium in your hand.
The Front-Label Trap, Explained in 30 Seconds
Magnesium glycinate is magnesium bound to glycine. When a label gives the weight of the whole compound, the glycine counts too.
Double Wood explains this on its own label, and we give them credit for it: each capsule holds 400 mg of magnesium glycinate, which works out to about 60 mg of elemental magnesium.
Elemental magnesium is the number to compare across brands. So that's the number we put first.
Read the back of the bottle instead of the front, and the rankings change.
What Magnesium Glycinate Can (and Can't) Do for You
Straight talk, before we get to the rankings:
Can add a clearly measured amount of magnesium to your daily intake.*
Can provide magnesium in a glycinate or amino-acid-chelated form.*
Can't guarantee better sleep, relaxation or symptom relief for every person.
Can't replace medical advice when deficiency, kidney disease or medications are involved.
If a brand promises you more than this, be careful. Now let's look at how to compare the bottles in front of you.
The 5 Questions That Separated the Winner From the Rest
We scored every product on the same five things. Take this list with you and use it on any bottle you're thinking about buying.
Ask these before you buy:
How much elemental magnesium is in one daily serving?
Is it glycinate or bisglycinate, or a mix with other forms?
How many capsules or tablets does a full serving take?
What else is in the capsule: binders, coatings, fillers?
What does a day cost at the labeled serving?
One formula came out ahead on almost every question. You'll see which one below, plus the cleanest label and the best budget pick.
What to Look For Before You Buy
Elemental magnesium: This is the magnesium amount to compare across products, not the larger chelate number.
Form: Look for glycinate or bisglycinate if that is the form you specifically want.
Daily serving: A good formula still has to fit the number of pills you will actually take.
Other ingredients: Compare capsule shells, binders, coatings and excipients if a shorter formula matters to you.
Real daily cost: Compare the price at the labeled daily routine, not simply the bottle price.
4 Red Flags That Should Make You Put the Bottle Back
Front-label math: A large “mg” number may describe the chelate, not elemental magnesium.
Hidden routine: Two tablets per serving can become four tablets when you read the directions.
Wrong comparison: Do not compare compound weight from one bottle with elemental magnesium from another.
Price alone: A cheap bottle can still deliver less elemental magnesium per capsule or require more pills.

120 mg magnesium as magnesium glycinate per vegetarian capsule.
Daily serving
Vegetarian capsules; 90, 180 and 360-count sizes
Price
$27 for 90 capsules; $46.50 for 180
Ratings
Professional-brand formula; sold through practitioners and retailers
Pros
120 mg elemental magnesium per capsule
Very short ingredient list
No magnesium stearate
Free from many common allergens
Flexible 1–4 capsule dosing
Established professional supplement brand
Cons
Multiple capsules for higher intake
Directions split doses with meals
Higher cost at larger daily intakes
Bottom Line
Pure Encapsulations deserves the #2 spot because its formula is exceptionally straightforward: 120 mg magnesium glycinate per capsule with a short excipient list and flexible dosing. It is a strong choice for buyers who prioritize minimal added ingredients. Earth Energy ranks above it for this page because its 275 mg daily serving is easier to understand as a complete once-daily routine rather than building your intake one capsule at a time.
200 mg elemental magnesium from 2,000 mg magnesium lysinate glycinate chelate per 2-tablet serving.
Daily serving
Tablets; 120-count and 240-count options
Price
$13.99 direct for 120 tablets
Ratings
Albion TRAACS chelate; vegan, non-GMO and gluten-free
Pros
200 mg elemental per serving
2,000 mg chelate also disclosed
Albion TRAACS chelate
Very strong price
Vegan and gluten-free
Long-established formula
Cons
Lysinate glycinate, not glycinate alone
Suggested routine can reach four tablets
Longer excipient list
Bottom Line
Doctor's Best is hard to beat on price. The label clearly separates 200 mg of elemental magnesium from 2,000 mg of lysinate glycinate chelate, and Albion TRAACS gives the formula a recognizable ingredient pedigree. The main trade-off is routine: its suggested use is two tablets twice daily, and the tablet formula needs more excipients. Earth Energy ranks higher because its once-daily 275 mg serving is simpler for the buyer who values convenience as well as dose.
400 mg magnesium glycinate per capsule, providing about 60 mg elemental magnesium.
Daily serving
180 capsules; vegan, gluten-free and non-GMO
Price
$19.95 current direct price
Ratings
4.8/5 from 120 reviews; 30-day guarantee
Pros

180 capsules per bottle
$19.95 direct price
Vegan and non-GMO
Heavy-metal and microbial testing
Cons
60 mg elemental per capsule
400 mg front number needs context
Globally sourced ingredients
Bottom Line
Double Wood is exactly why reading the Supplement Facts matters. Each capsule contains 400 mg of magnesium glycinate, but the company explains that this equals about 60 mg of elemental magnesium. That transparency is a strength, not a criticism, and its published COAs are excellent. Earth Energy ranks higher because it delivers 275 mg elemental magnesium in one defined daily serving, making the dose easier to understand without doing extra math.
200 mg elemental magnesium from Albion magnesium bisglycinate per 2-tablet serving.
Daily serving
Tablets; 90 and 180-count sizes
Price
$14.39 sale for 90 tablets
Ratings
Non-GMO, vegan, kosher and made without gluten
Pros
200 mg elemental magnesium
Albion bisglycinate
Low entry price
Vegan and non-GMO
Multiple bottle sizes
Established family-owned brand
Cons
Two to four tablets daily
More tablet excipients
Sale pricing can change
Bottom Line
NOW gives buyers a recognizable Albion bisglycinate formula at a very accessible price. Two tablets provide 200 mg elemental magnesium, and the 90-tablet bottle is inexpensive. The trade-off is that the suggested routine can reach four tablets per day and the tablet format carries more inactive ingredients. Earth Energy ranks higher for buyers who want a more concentrated once-daily serving and a simpler decision at the label.

Questions people ask
What number should I compare on magnesium glycinate labels?
Compare the amount labeled simply as “Magnesium” in the Supplement Facts panel. That is the elemental magnesium amount. A bottle may also list the much larger weight of magnesium glycinate or another chelate. Those numbers describe different things, so comparing them directly can make one product look stronger than it actually is.
Is 400 mg magnesium glycinate the same as 400 mg magnesium?
No. “400 mg magnesium glycinate” can describe the weight of the magnesium-and-glycine compound, not 400 mg of elemental magnesium. Double Wood, for example, states that a 400 mg magnesium glycinate capsule contains about 60 mg elemental magnesium. Always check the Supplement Facts panel before comparing doses.
Why is Earth Energy ranked first if you own it?
We disclose that ownership on every page. Every product is scored on the same published criteria, and we show the label details and prices we compared so you can check our work.
How does Earth Energy compare with Doctor's Best?
Earth Energy provides 275 mg elemental magnesium from 2,500 mg magnesium glycinate in three capsules once daily. Doctor's Best provides 200 mg from 2,000 mg magnesium lysinate glycinate chelate per two tablets, with directions for two tablets twice daily. Doctor's Best is cheaper; Earth Energy ranked higher for the simpler once-daily routine and focused glycinate positioning.
Is magnesium glycinate better than magnesium oxide?
They are different magnesium forms. Glycinate is commonly chosen when buyers want an amino-acid-chelated form and often prefer it for gastrointestinal tolerance. That does not make it universally better for every person or purpose. Compare the form, elemental magnesium, serving size, price and your own healthcare needs.
How we compared these supplements
We reviewed current Supplement Facts panels, suggested use, ingredient lists and direct-brand pricing. We gave the most weight to elemental magnesium and label clarity because front-label compound weights can make otherwise similar magnesium products difficult to compare.
