NOW Magnesium Glycinate Review: Label, Dose, Form and Value

Quick verdict: NOW Foods Magnesium Glycinate Tablets are a straightforward chelated magnesium product providing 200 mg of elemental magnesium per 2-tablet serving from magnesium bisglycinate (Albion). The formula is transparent and the elemental dose is easy to identify. The tradeoff is tablet count: the manufacturer’s suggested use can reach 400 mg per day from the product, which exceeds the U.S. adult supplemental UL of 350 mg/day unless used with individualized guidance.

What’s in It?

The official NOW label lists 200 mg of elemental magnesium per two tablets, equal to 48% of the FDA Daily Value. It identifies the source as magnesium bisglycinate (Albion). The label also lists several tablet and coating ingredients, including citric acid, hydroxypropyl cellulose, stearic acid, silicon dioxide, hypromellose, sunflower lecithin, triethyl citrate, and sunflower oil.

Ingredient Form

Bisglycinate is a chelated form in which magnesium is associated with glycine. It is a reasonable form for consumers who prioritize gastrointestinal tolerance. The important advantage here is not a promise of a special therapeutic effect; it is that the form and elemental amount are clearly disclosed.

Dose Analysis

One labeled serving gives 200 mg elemental magnesium. Two servings would give 400 mg. That distinction matters because the NIH adult upper limit for magnesium from supplements and medications is 350 mg/day, a value based primarily on gastrointestinal adverse effects. The UL does not include food magnesium.

What Does the Evidence Say?

The evidence supports magnesium as an essential nutrient and supports supplementation when intake is inadequate or a clinical indication exists. Evidence for specific outcomes varies. A product’s chelated form does not convert broad marketing claims into proven benefits for every user.

Testing & Manufacturing

NOW states that the product is made and quality tested in the United States with globally sourced ingredients and lists Intertek GMP Supplement Certification among its product attributes. NuraWise distinguishes manufacturer claims and certification listings from independent testing of the specific retail lot. We have not independently laboratory-tested this product.

Cost per Serving

Price is a changing variable. NuraWise records price only with a date and seller. The official NOW site listed the 90-tablet size at a sale price of $14.39 when checked on August 11, 2026; that equals roughly $0.32 per 200 mg serving before shipping or taxes. Recheck before purchase.

Pros

• Clearly stated elemental magnesium dose
• Chelated bisglycinate form
• 200 mg per serving is easy to compare
• Vegan and non-GMO attributes listed by manufacturer
• Large established manufacturer

Cons

• Two tablets per serving
• Following the maximum suggested use gives 400 mg supplemental magnesium/day
• Price and availability can change
• No NuraWise hands-on or independent laboratory test has been performed

Who Might Consider It?

Someone looking for a clearly labeled bisglycinate product and a 200 mg serving may find this formulation convenient. Individual need should still be based on diet, total supplemental intake, tolerance, and health context.

Who Should Be Careful?

People with kidney disease, those taking medicines that interact with magnesium, pregnant or breastfeeding people, and anyone considering doses above routine self-supplementation levels should seek individualized guidance.

NuraWise Score

Status: Pending. NuraWise will not issue a numeric score until the public scoring methodology and all required verification fields are complete. This prevents an arbitrary score from being presented as objective.

Bottom Line

NOW Magnesium Glycinate Tablets have a transparent label and a practical 200 mg elemental dose per serving. The main caution is not the form; it is total daily dose. Compare the amount you actually need with food intake and all other magnesium sources rather than automatically following the maximum serving suggestion.
