What Is the Best Magnesium Supplement for Men?
The best magnesium for men is glycinate, and our pick is Nature’s Truth Magnesium Glycinate 200 mg: NSF International lists it, and 2 capsules give 200 mg for $0.30 a day. Add food and you reach a man’s 400 to 420 mg. We checked 31 glycinates; six are on a testing list.

Why we pick it This is a tested 200 mg: NSF’s testing list names it, and 2 capsules give 200 mg for $0.30 a day, the lowest cost of the six on a testing list. That leaves 200 to 220 mg for food to reach a man’s 400 to 420 mg, and NIH’s limit for supplements is 350 mg.
How much magnesium does a man need?
NIH says men need 400 to 420 mg of magnesium a day in total, from food, drinks and supplements together. By age that is 410 mg for boys 14 to 18, 400 mg for men 19 to 30, and 420 mg for men 31 and older.
For supplements NIH sets a separate cap of 350 mg a day for adults. It counts only “dietary supplements and medications,” not food. The dose that fits both numbers is a supplement of 350 mg or less, and food covers the rest: NIH lists 156 mg in an ounce of roasted pumpkin seeds and 80 mg in an ounce of dry roasted almonds. A 200 mg supplement leaves 200 to 220 mg to come from meals.
Which glycinate fits you?
2. The same 200 mg, on a different list: Nature Made Magnesium Glycinate
Nature Made’s label gives 200 mg of bisglycinate in 2 capsules, and USP (United States Pharmacopeia) Verified lists “Nature Made High Absorption Magnesium Glycinate 200mg Capsules.” The bottle holds 60 capsules, a 30-day supply.

3. Set your own dose: Thorne Magnesium Bisglycinate Powder
One scoop gives 200 mg, and NSF/ANSI 173 lists “Thorne Magnesium Bisglycinate” as a powder with a 3.77 g scoop. Two scoops would be 400 mg, above the 350 mg limit. Thorne’s stick packs are on the same list, one stick a day.

4. More in one serving: Ritual Magnesium+
Ritual gives 300 mg of bisglycinate in a drink mix, with tart cherry powder, and NSF/ANSI 173 lists it. That is 100 mg more than our pick, for $1.87 a day.

6 of 31 glycinate supplements are on a testing list
We counted glycinate-only products that give 200 mg or more at the label’s lowest daily amount: 31. Six are on a testing list that names the exact product, and all six give 200 to 300 mg a day, under NIH’s cap. Four of the 31 give more than 350 mg a day, and none of those four is on a list.
Want the lowest price? BulkSupplements’ capsules are $0.23 a day, but one serving is 400 mg, above NIH’s 350 mg limit, and they are on no testing list.

Questions men ask
Do men need a different magnesium than women?
NIH lists a higher daily total for men than for women. The pick and the 200 mg dose are the same for either, and NIH’s limit from supplements is the same for every adult.
What does NSF/ANSI 173 check?
The list names the product and the serving, so you can match the name on your bottle to the name on the list.
What should the label say?
Look for a line that reads “Magnesium 200 mg” with the form after it, such as glycinate or bisglycinate. Some labels print the weight of the whole compound, which is a bigger number than the magnesium in it; use the line that says Magnesium. See magnesium forms compared for the other forms.
How we picked
We started from the question men ask: which magnesium, which brand, and how much. On November 12, 2026 we read NIH’s amounts, then the labels of 31 glycinate-only supplements sold on Amazon and the testing lists: NSF/ANSI 173 on November 12, 2026, USP Verified on November 11, 2026 and Informed Sport on November 9, 2026. Prices are Amazon’s, read November 12, 2026.
