Magnesium Gummies: How Much Magnesium They Really Deliver
Of the 26 magnesium gummy labels we read in NIH’s database, the middle one gives 100 mg of magnesium in 2 gummies, and none reach 300 mg a day. No study we found compares how well a gummy and a capsule are absorbed; the difference is how much magnesium each piece holds. If you want a gummy, buy Nature Made Magnesium Glycinate Gummies (USP Verified). If you want a full dose for less, a capsule gives twice the magnesium per serving, and per mg the gummies cost about 6.3 times as much.

For a full dose: Revive MD Magnesium Glycinate, our pick for most people on the best magnesium page. It gives 200 mg in 2 capsules for $0.33 a day at Revive MD’s own price, and it is on the Informed Sport list. Getting the same 200 mg from the gummies takes 4 gummies and costs $2.10 a day.
How much magnesium do gummies give?
Less than most people expect. We read every magnesium gummy label we could find in the NIH Dietary Supplement Label Database (26 sold as magnesium, read September 15, 2026):
- The median serving is 100 mg of magnesium, from 2 gummies.
- 32% of the 26 labels give under 100 mg a day when you follow the directions.
- None reach 300 mg a day. The biggest single serving we found was 250 mg.
- Almost all use citrate (96% of labels). Nature Made’s is the only glycinate gummy in the set.
Why so little? A gummy weighs a few grams, and most of that is gel and sugar. Magnesium is only part of the compound it comes in (about 16% of magnesium citrate). There is no room for more.
| Item | Value (mg) |
|---|---|
| Vitamatic “600 mg” gummies | 70 mg |
| Median gummy label | 100 mg |
| Nature Made gummies | 100 mg |
| Revive MD capsules | 200 mg |
| Upper limit from supplements | 350 mg |
The “600 mg” gummy that holds 70 mg
Some gummies put the weight of the whole compound on the front. Vitamatic Magnesium Citrate Gummies 600 mg is the clearest case. Its Supplement Facts panel lists magnesium citrate 600 mg and, on its own line, magnesium 70 mg per 2 gummies (NIH label 283034). The 70 mg is the dose. To get 300 mg you would need about 9 gummies, and the label says 2 a day.
Not every brand does this. Another citrate gummy in NIH’s label database holds the same 70 mg in 2 gummies and is named “70 mg” on its front (NIH label 272274).
Bigger gaps have been challenged. On April 27, 2026, the advertising watchdog NAD reviewed a gummy sold as “Magnesium Glycinate Gummies 200 mg Per Serving” whose panel showed 22 mg of magnesium. NAD recommended dropping the claim, and the brand, Nature’s Truth, agreed. The case was brought by Pharmavite, the maker of Nature Made (NAD decision).
The rule: The “Magnesium” line on the Supplement Facts panel is the magnesium itself (the elemental amount), not the weight of the whole compound (NIH).
What gummies cost per mg of magnesium
Gummies cost more for the same magnesium. Prices are each brand’s own list price; cost is for 300 mg of magnesium, so products with different servings compare fairly.

Who should take a gummy?
- A gummy makes sense if you cannot or will not swallow pills, or you only want a small top-up of about 100 mg on top of food.
- A capsule makes more sense if you want 200 mg or more. You take fewer pieces, skip the sugar and pay less per mg at list price. How much magnesium you need.
- Count every product. Gummies, multivitamins and antacids all add to the magnesium you take from supplements.
- Keep them away from children. A gummy looks like candy. Children’s limits are much lower than adults’: 65 mg a day from supplements at ages 1 to 3 and 110 mg at 4 to 8 (NIH).
How we read the gummy labels
We searched the NIH Dietary Supplement Label Database on September 15, 2026 for labels whose form is a gummy and whose panel lists magnesium. 64 came back; 26 are sold as magnesium (we left out 38 multivitamin, calcium-magnesium, sleep and electrolyte gummies). The dose is the panel’s “Magnesium” line, never a line named for the compound. A day is that dose times the most servings the label allows. We split the labels into two halves and print only the figures that came out the same in both. The data is free to reuse: download the data (JSON) (CC BY 4.0). It cannot tell you how many bottles of each are sold, or whether a gummy holds what its label says. That is what a testing list checks.
Frequently Asked Questions
How much magnesium is in a magnesium gummy?
On the labels we read, the middle serving is 100 mg of 2 gummies. On the 26 gummy labels we read in NIH’s label database, servings ran from 70 to 250 mg, and none reached 300 mg a day. Read the “Magnesium” line on the Supplement Facts panel, not the number on the front.
Why does a “600 mg” magnesium gummy only contain 70 mg of magnesium?
The 600 mg is the weight of the whole magnesium citrate compound. Magnesium is only a small part of it. Vitamatic’s panel lists both: magnesium citrate 600 mg and magnesium 70 mg in 2 gummies. Only the 70 mg is your dose.
Are magnesium gummies as good as pills?
The magnesium is the same, but a gummy holds much less of it. Nature Made’s gummies give 100 mg in 2 gummies; our capsule pick, Revive MD, gives 200 mg in 2 capsules. Per 300 mg of magnesium, the gummies cost about 6.3 times as much as Revive MD’s capsules at list price. Gummies make sense if you cannot swallow pills or only want a small top-up.
What is the best magnesium gummy?
Nature Made Magnesium Glycinate Gummies 100 mg: 100 mg of magnesium (as glycinate) in 2 gummies, on USP Verified, $1.05 a serving at list price. It is the only gummy we score that is on a public testing list.
Can you take too many magnesium gummies?
Yes, if you take several servings. The upper limit for adults is 350 mg a day of magnesium from supplements and medicines. Food does not count toward it (NIH). Four servings of a 100 mg gummy reach 400 mg. Loose stools are the first sign of too much. If you have kidney disease, ask your doctor before you take magnesium. Weak kidneys cannot clear the extra, so it can build up (NIH).
How much sugar is in magnesium gummies?
About 3 g a day on the median label that lists sugars. Nature Made’s and Vitamatic’s gummies each have 4 g in a 2-gummy serving. Getting 200 mg of magnesium from Nature Made’s gummies means 4 gummies and 8 g of sugar.
When should I take magnesium gummies?
Any time of day that you will remember. If you take antibiotics or osteoporosis drugs, space them from magnesium. Best time to take magnesium.
