From the lab

Why we landed on Strong Buy

A strong value pick for shoppers who want a clearly labeled magnesium bisglycinate tablet, with a careful look at serving size and daily intake.

Who we'd buy it for Budget-minded shoppers who want a plain, clearly labeled bisglycinate tablet and will check the amount against their own needs.

Who we'd tell to skip it You prefer capsules, need a sport-certified batch, or are looking for a guaranteed sleep aid.

The part we will not talk past The labeled serving is two tablets

Pros

  • The label identifies the bisglycinate source and elemental magnesium amount
  • A familiar, widely available supplement brand
  • A public independent lab result is available for one retail sample

Cons

  • The labeled serving is two tablets
  • Following the maximum label direction can exceed the adult supplemental magnesium upper limit
  • This is not a proven sleep treatment

NOW Magnesium Glycinate is our value pick for shoppers who want a plain bisglycinate supplement with a clear elemental-magnesium label. We like the named chelate source and the straightforward formula; the main tradeoff is the tablet serving and the need to keep total supplemental magnesium in view. Use AFF20 through the tracked HerbsPro listing and check the current terms on our HerbsPro promo code page.

Why we recommend it

The label makes the form and amount easy to compare. NOW identifies Albion magnesium bisglycinate as the source and lists 200 mg of elemental magnesium in a two-tablet serving. That is more useful than a front-label compound weight by itself because elemental magnesium is the figure shoppers compare across Supplement Facts panels.

It keeps the formula focused. This is a single-mineral product rather than a blend with several ingredients and a proprietary total. NOW lists the tablet and coating ingredients separately, and the package identifies the product as vegan. That gives a label-focused shopper a clean starting point for comparing forms and serving routines.

There is public testing context, with limits. A published review examined an independently tested retail sample of this product and reported a result consistent with the label claim. That evidence is more informative than a general “quality tested” badge, but it is tied to one older sample. It does not certify every current bottle or show that the supplement creates a particular health result.

What buyers love

Feedback on the exact product commonly points to the simple formula, accessible value, and easy place in a daily routine. Some buyers find the tablets easy to take; others mention their size or different stomach tolerance. Those are useful practical themes, not proof that magnesium improves sleep, stress, cramps, or any other individual outcome.

The clearest reason to choose it is therefore the label and format: buyers who want a recognizable bisglycinate tablet can see the form and elemental amount without decoding a multi-ingredient blend.

Who it’s for (and who should skip it)

A good fit for shoppers comparing magnesium products who prefer tablets, want a familiar manufacturer, and value a clearly stated elemental amount. It also suits buyers who want to compare an uncomplicated bisglycinate formula against powders, gummies, and multi-form blends.

Choose another format if you find tablets difficult to swallow, want a powder that is easier to adjust by serving, or specifically need a batch certification for sport. Ask a qualified clinician before supplementing if you have kidney disease, take medicines that may interact, are pregnant or nursing, or are unsure how much magnesium you need.

How it compares

The NOW tablet is the budget-oriented option in our best magnesium for sleep and recovery guide. For a powder format and a different quality-documentation profile, compare our Thorne Magnesium Bisglycinate review. The right choice depends on form, label detail, total daily intake, and price; no product here is a guaranteed sleep solution.

How to get the best price

Open the exact NOW product through our tracked HerbsPro link, add the 180-tablet listing to your cart, and enter AFF20. We verified that the code applied to this item, though the offer did not apply to every product we checked. Review the current HerbsPro offer terms and confirm the final cart total before paying.

Our verdict

NOW Magnesium Glycinate earns our Strong Buy recommendation as a value-focused, clearly labeled bisglycinate tablet. The code-backed HerbsPro route makes it especially easy to compare the current offer. Keep the serving directions and your total supplemental magnesium in view, then use AFF20 on the eligible listing if the checkout still shows the discount.

Who it's for

Budget-minded shoppers who want a plain, clearly labeled bisglycinate tablet and will check the amount against their own needs.

Who should skip it

You prefer capsules, need a sport-certified batch, or are looking for a guaranteed sleep aid.

Frequently asked questions

Is there a HerbsPro promo code for NOW Magnesium Glycinate?
Yes. AFF20 applied to the current HerbsPro 180-tablet listing when we checked it. See our [HerbsPro promo code page](/deals/herbspro-promo-code-2026/) for the verified product scope, then confirm the discount and final total in your cart.
What form of magnesium is in NOW Magnesium Glycinate?
NOW identifies the source as Albion magnesium bisglycinate. The label lists 200 mg of elemental magnesium per two-tablet serving; check the current package in case the formula changes.
Is NOW Magnesium Glycinate a sleep supplement?
It is a magnesium supplement, not a proven insomnia treatment. Evidence for magnesium as a routine sleep aid remains uncertain; our [magnesium guide](/best-picks/best-magnesium-for-sleep-recovery/) compares the product with other formats and explains the evidence.
How many tablets are in a serving?
The current label defines a serving as two tablets and lists 200 mg of elemental magnesium. Its suggested use allows more than one serving per day, so compare total supplemental magnesium with your clinician's advice and the adult upper limit.
What are the main drawbacks?
The tablet format and two-tablet serving will not suit everyone, and the maximum label direction can take supplemental magnesium above the adult upper limit. People report different levels of stomach comfort, so follow the label and ask a clinician about medicines or health conditions.
