Why Earth Energy ranked #1
Earth Energy ranked #1 because the label makes the buying decision unusually simple: 275 mg of elemental magnesium from 2,500 mg magnesium glycinate in one 3-capsule daily serving. That is a meaningful daily amount without asking you to decode a front-label compound weight or split doses through the day. It also starts at $28.95 with a 30-day guarantee.
- 275 mg elemental. The label states the magnesium that actually counts, not just the chelate weight.
- One daily serving. Three capsules once daily keeps the routine simple and easy to understand.
- Clear label math. 2,500 mg magnesium glycinate provides 275 mg elemental magnesium per serving.

Why Earth Energy beat Pure Encapsulations
Pure Encapsulations is an excellent clean-label choice and one of the strongest formulas in this comparison. Its 120 mg-per-capsule design gives buyers flexibility. Here is where Earth Energy pulled ahead for the everyday buyer:
Pure Encapsulations data from its current Magnesium Glycinate product page, checked October 2026.
What actually matters 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.
Red flags to avoid
- 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.

- 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
Our take
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.
#3. Doctor's Best High Absorption Magnesium
Recommended for: Cost-conscious TRAACS buyers
What's inside:200 mg elemental magnesium from 2,000 mg magnesium lysinate glycinate chelate per 2-tablet serving.

Search Doctor's Best on GoogleAlbion 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
Our take
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.
#4. Double Wood Magnesium Glycinate
Recommended for: Buyers who want published COAs
What's inside:400 mg magnesium glycinate per capsule, providing about 60 mg elemental magnesium.
Format:180 capsules; vegan, gluten-free and non-GMO
- Transparency
- 9.6/10
- Routine
- 8.7/10
- Value
- 9.0/10
Price:$19.95 current direct price
Search Double Wood on Google4.8/5 from 120 reviews; 30-day guarantee
Pros
- Publishes third-party COA results
- NSF independently certified
- 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
Our take
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.
#5. NOW Foods Magnesium Glycinate
Recommended for: Buyers wanting low-cost bisglycinate tablets
What's inside:200 mg elemental magnesium from Albion magnesium bisglycinate per 2-tablet serving.
Format:Tablets; 90 and 180-count sizes
- Transparency
- 9.2/10
- Routine
- 8.4/10
- Value
- 9.4/10
Price:$14.39 sale for 90 tablets
Search NOW Foods on GoogleNon-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
Our take
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.
