10 Best Magnesium Glycinate Supplements (2026)

Doctor's Best has been the go-to magnesium glycinate for years, and for good reason. Each serving delivers 200mg of elemental magnesium from pure magnesium lysinate glycinate chelate (Albion TRAACS). The absorption is noticeably better than cheaper alternatives — most users report feeling effects within the first week.

The tablets are on the larger side, which is our only real complaint. But at roughly $0.07 per serving, the value is unbeatable for a quality chelated magnesium.

If you have sensitivities or allergies, Pure Encapsulations is the brand your doctor probably recommends. Their hypoallergenic formula is free from gluten, GMOs, artificial colors, flavors, sweeteners, coatings, shellacs, and unnecessary binders. It's also third-party tested by Eurofins and NSF.

The downside? You need 4 capsules to get the full 120mg serving, and the price per serving is roughly 3x Doctor's Best. But for people who react to fillers or need pharmaceutical-grade purity, it's worth every penny.

NOW Foods delivers solid quality at the lowest price point in our roundup. Their magnesium glycinate tablets provide 200mg of elemental magnesium per 2-tablet serving, manufactured in a GMP-certified facility. It's a no-frills option that gets the job done.

The formula does contain stearic acid and silicon dioxide as flow agents, which some purists prefer to avoid. But for most people, these are perfectly safe and allow NOW to keep costs down significantly.

Life Extension takes a different approach by combining magnesium glycinate with citrate and oxide in one capsule. The idea is you get the gentle absorption of glycinate plus the higher elemental content of oxide. It's a smart formulation for people who need higher doses without taking a handful of pills.

The trade-off is that it's not pure glycinate — if you specifically need the calming glycine component, you're getting less of it per serving. But for general magnesium supplementation, this is an excellent and affordable choice.

Thorne is the supplement brand trusted by professional athletes, and their magnesium bisglycinate is NSF Certified for Sport — meaning it's tested for banned substances. If you're a competitive athlete subject to drug testing, this is your safest bet.

The quality is impeccable, but you're paying for it. At roughly $0.50 per serving, it's the most expensive option on our list. They also offer a powder form that mixes into water, which is great if you hate swallowing pills.

If you can't stand swallowing pills, KAL's chewable magnesium glycinate is a game-changer. The orange vanilla flavor is genuinely pleasant — not that chalky, artificial taste you'd expect from a chewable supplement. Each tablet delivers 200mg of magnesium from glycinate.

Nested Naturals uses vegan capsules and sources their magnesium glycinate without any animal-derived ingredients. They're also transparent about their third-party testing — every batch is tested by an independent lab and results are available on request.

While technically magnesium L-threonate (not glycinate), we're including this because many people searching for glycinate are really looking for the best magnesium for brain health. Magtein is the only form clinically shown to cross the blood-brain barrier effectively, making it superior for cognitive support and memory.

Nature Made is the #1 pharmacist-recommended supplement brand, and their magnesium glycinate is USP verified — meaning an independent organization has confirmed the product contains what the label says. If you want a safe, reliable option from a brand you can find at any pharmacy, this is it.

BioSchwartz has quickly become one of the best-selling magnesium supplements on Amazon, and the reviews back it up. Their formula provides 200mg of elemental magnesium from bisglycinate chelate, with no artificial fillers. The capsules are smaller than Doctor's Best tablets, making them easier to swallow.
