Magnesium Glycinate at CVS: Brands, Doses & Prices (2026)

Key takeaways

• CVS stocks three main magnesium glycinate brands: CVS Health (200mg), Nature Made (200mg), and Nature's Bounty (240mg and 360mg). Selection is narrow, and most options cluster at the low end of what sleep research uses.
• Sleep studies on magnesium typically use 200 to 500mg of elemental magnesium. Only the Nature's Bounty Advanced 360mg matches the mid-range of that research dose.
• "Magnesium gummies" and "chewables" at CVS are usually citrate or oxide, not glycinate. If you want the glycinate form specifically, stick to capsules.
• For general deficiency top-up, any CVS option works. For sleep specifically, pick the higher-dose Nature's Bounty or look beyond the pharmacy aisle for a single-ingredient clinical dose.

What magnesium glycinate does CVS actually sell?

CVS stocks magnesium glycinate under its own store brand plus two of the biggest mass-market supplement brands. The selection is narrower than you might expect, and the doses are consistently on the lower end of what sleep research uses.

Here is what you will typically find on the shelf or on cvs.com:

Prices fluctuate and vary by location. Confirm on cvs.com before planning a trip.

A few things worth noting once you have the options in front of you. CVS Health is the store brand and is usually the cheapest on a per-capsule basis. Nature Made is the most broadly trusted mass-market brand in the US pharmacy channel, and it tends to be the #1 pharmacist-recommended supplement line for most categories it competes in. Nature's Bounty Advanced at 360mg is the only option on CVS shelves that sits squarely inside the dose range used in most magnesium sleep studies.

A few forms people search for are not really stocked. There is no magnesium glycinate-specific powder or liquid routinely on the shelf. Most "magnesium powder" at CVS is magnesium citrate (Natural Vitality Calm is the usual anchor SKU) or magnesium oxide, both of which are different compounds with different absorption profiles and different uses. Gummies and chewables labeled "magnesium" rarely use the glycinate form, because the amino-acid chelate is bulky and has a gritty taste that is difficult to mask in a confection format.

If you want a clinical-dose, single-ingredient option, brands like SleepStack deliver 275mg of magnesium glycinate per serving in three capsules, which is what sleep research typically uses. For a quick pharmacy pickup, though, the options above cover most common needs.

The shelf at your local CVS will vary, and online stock sometimes differs from in-store. Call ahead if you are driving for a specific SKU.

Which CVS magnesium glycinate is best for sleep?

Of what CVS stocks, Nature's Bounty Advanced Magnesium Glycinate (360mg) is the closest to the dose used in sleep research.

Sleep research on magnesium typically uses 200 to 500mg of elemental magnesium per day. A small randomized trial in older adults with insomnia (Abbasi et al. 2012, PMID 23853635) used 500mg of magnesium oxide (not glycinate) and found significant improvements in insomnia severity, sleep efficiency, and sleep onset latency, though total sleep time did not change significantly. A sleep-physiology review (Nielsen et al. 2010) discussed improvements in sleep indicators in adults over 51 with poor sleep. A later review focused on magnesium glycinate tolerability and clinical use (Djokic et al. 2019) summarized the evidence for glycinate as a better-tolerated form compared to oxide or citrate.

Against that research range, here is how the CVS options look:

• 200mg (CVS Health, Nature Made): at the bottom of the therapeutic range. Within scope if you are deficient, but on the low side for sleep-specific use. People who find 200mg underwhelming often take two capsules, which puts them at 400mg.
• 240mg (Nature's Bounty standard): slightly higher, still on the lower side.
• 360mg (Nature's Bounty Advanced): middle of the research range. This is the sweet spot for sleep use of what is stocked.

A note on the upper limit. The Tolerable Upper Intake Level (UL) for supplemental magnesium in adults is 350mg per day, per the NIH Office of Dietary Supplements. The UL is set based on the dose at which loose stools become more likely, not on serious toxicity. Many sleep studies use doses above the UL short-term under clinical supervision. For routine self-supplementation, staying near or slightly under the UL is the practical approach, and anyone managing kidney disease, taking prescription medications, or pregnant should discuss dosing with a doctor.

How does CVS magnesium glycinate compare to what research uses?

A quick honest read of the CVS aisle against the research.

Form. Glycinate is the right form. All of CVS's glycinate-labeled products use the chelated bisglycinate form, which absorbs substantially better than oxide (the form in many cheap "magnesium" supplements, with absorption in the single-digit percentage range per NIH) and causes far less gastrointestinal upset than citrate at equivalent doses. On form alone, CVS is fine.

Dose. The 200mg options are sub-clinical for sleep if taken as one capsule. The 240mg Nature's Bounty is borderline. The 360mg Nature's Bounty is appropriate. If you are targeting sleep specifically, dose matters as much as form.

Single-ingredient vs blend. Most CVS glycinate SKUs are single-ingredient, which is what you want for a targeted sleep or anxiety use case. A handful of Nature's Bounty variants bundle calcium, vitamin D, or zinc. Those blends can be useful for general bone or immune support, but they complicate the picture if you are trying to isolate the effect of magnesium.

Third-party certifications. Nature Made is USP Verified, which is an independent third-party audit of ingredient identity, potency, and contaminants. It is the most trusted supplement certification in the US pharmacy channel. CVS Health and Nature's Bounty do not publish USP verification for these specific SKUs, though both brands carry separate manufacturing-level credentials (NSF or GMP). If third-party testing matters to you, Nature Made is the pick.

Practical guidance: what to pick at CVS

A decision tree if you are standing in the aisle.

• Just want to try magnesium glycinate for general wellness? CVS Health 200mg, 120-count. Lowest price per capsule and the molecule is the same as anything more expensive.
• Want a known brand with USP third-party verification? Nature Made High Absorption Magnesium Glycinate.
• Targeting sleep specifically and want a single capsule, single dose? Nature's Bounty Advanced 360mg is the only CVS option inside the research range.
• Want a clinical-dose, single-ingredient glycinate without a multi-vitamin blend, and you are open to ordering online? CVS doesn't really stock this. Most clinical-dose single-ingredient glycinate lives in the direct-to-consumer channel. Brands like SleepStack ship 275mg per serving direct, with a 30-night guarantee, which is a different buying proposition than the pharmacy aisle.

A few practical notes that apply regardless of which you pick:

• Timing. For sleep use, 30 to 60 minutes before bed is the general guidance.
• Food. Magnesium glycinate is generally well tolerated on an empty stomach, but if you get any mild stomach discomfort, take it with food.
• Start low. Begin with one capsule of a 200mg product for a few nights. If well tolerated and you want more effect, you can step up over a week.
• Give it time. Anecdotally, many people feel a difference on night one. In research settings, sleep quality changes are usually measured over one to eight weeks.
• Talk to your doctor. If you take prescription medications (especially antibiotics, bisphosphonates, or diuretics), have kidney disease, or are pregnant, confirm dosing with your clinician before starting.

If your sleep problems are severe, chronic, or accompanied by symptoms like loud snoring, gasping, or persistent daytime exhaustion, supplements are not the answer. See a doctor about a sleep assessment.

Frequently Asked Questions

Is CVS magnesium glycinate the same as the more expensive brands?

Chemically, yes. A chelated magnesium bisglycinate is a chelated magnesium bisglycinate regardless of brand. Quality differences show up in third-party testing (USP Verified vs no verification), filler selection (some brands use cleaner excipients), and dose accuracy (how close the actual capsule is to the label claim). The molecule itself does not change.

What is the strongest magnesium glycinate at CVS?

Nature's Bounty Advanced Magnesium Glycinate at 360mg elemental magnesium per serving is the highest-dose glycinate CVS typically stocks. Stronger is not automatically better. The UL for supplemental magnesium in adults is 350mg, and exceeding it can cause loose stools. The 360mg dose is fine for most adults but is not a reason to double up without medical input.

Does CVS sell magnesium glycinate gummies?

CVS stocks a range of magnesium gummies, but most use magnesium citrate or oxide rather than glycinate. Glycinate does not gummy well, because the amino-acid chelate is bulky and has a gritty taste that is difficult to mask in a sweet confection format. If you specifically want glycinate, stick with capsules.

Can I take magnesium glycinate with NAC?

Yes. There are no documented interactions between magnesium glycinate and N-acetylcysteine, and both are commonly stacked for sleep or recovery use cases. As with any combination, check with a pharmacist if you take prescription medications or manage a chronic condition.

What kind of magnesium is good for fibromyalgia?

Research on fibromyalgia and magnesium is limited, but the most-studied forms are magnesium citrate and magnesium malate, not glycinate. Small trials have shown modest symptom improvement with magnesium supplementation, particularly when combined with malic acid. Anyone managing fibromyalgia should coordinate supplementation with the clinician who manages their condition.

How much does magnesium glycinate cost at CVS vs online?

CVS prices range roughly $14 to $22 for a one to two month supply of 200 to 360mg magnesium glycinate. Amazon, Costco, and direct-to-consumer brands can run cheaper per milligram on bulk SKUs, and some DTC brands bundle a money-back guarantee that the pharmacy aisle does not offer. If you value same-day pickup, CVS wins. If you value dose specificity and per-milligram cost, online usually wins.
