Shopping for a Magnesium Glycinate Supplement? Check These 6 Things Before You Buy.

The bottles all say "magnesium glycinate." They're not all the same. Here's a two-minute checklist for picking a good one, and how ours measures up.

You already know you want magnesium glycinate. Now you're staring at a page of bottles with the same name and very different prices.

The good news: you don't need a chemistry degree. You need to know where to look on the label.

Here's the checklist, item by item.

Editor's note: This article is an advertisement from Earth Energy, the maker of Magnesium Glycinate capsules. It's general education, not medical advice. Talk to your doctor before starting any supplement.

Number 2 is where most bottles quietly differ, and it's the first thing to check.

1.Check the Elemental Magnesium, Not Just the Big Number.

The front of the bottle may show the weight of the whole compound. The number that matters is the elemental magnesium and its % Daily Value, because that's the actual magnesium you're getting.

The takeawayCompare elemental mg and %DV across every bottle.

2.Check That It's Actually All Glycinate.

Some products labeled "magnesium glycinate" also contain other forms, such as magnesium oxide, in the same serving. That's allowed, but it's listed on the Supplement Facts panel, so read the magnesium line carefully.

The takeawayLook at what the magnesium comes from.

3.Check the Serving Size and How Often.

How many capsules or tablets is a serving, and how many times a day? Some products split the dose into two or more servings a day. Fewer daily doses is easier to stick with.

4.Check the Other Ingredients.

Fillers, binders, colors and flow agents all have to be listed under "Other ingredients." A shorter list is easier to understand.

5.Check the Price Per Serving, Not Per Bottle.

Bottles hold different numbers of servings. Divide the price by servings to compare fairly.

6.Check the Buying Terms.

Is the best price only available on a subscription? Is there a money-back guarantee? These matter as much as the label.
