Pure Encapsulations glycinate magnesium, compared with the rest of our magnesium shelf

Magnesium glycinate is the format people ask for by name at our counter more than any other mineral, and the price spread between bottles is wider than most shoppers expect. Below is the shelf laid out side by side, then the questions we get asked while someone is standing in front of it. Everything here is priced from our own feed, dated 30 July 2026.

Key takeaways

• The Pure Encapsulations 180-count runs $60.50, or $0.34 a capsule; the lowest per-capsule figure among the bottles featured here is $0.19.
• Bisglycinate and glycinate name the same magnesium-and-glycine compound — a bottle saying one is not offering something different from a bottle saying the other.
• Elemental magnesium is the weight of the magnesium itself, not the weight of the whole compound, which is why two bottles with the same milligram number on the front can differ.
• Powder versus capsule is the decision that actually changes daily life: 400 g and 145 g tubs versus 60, 120 and 180 counts.
• We stock 30 magnesium products across 8 brands; 8 of them are featured here.

The shelf at a glance

Per capsule, the order runs: ITL Health at $0.19, Naka Platinum's B6 version at $0.22, Naka Platinum's 200 mg elemental complex at $0.26, New Roots at $0.27 in the 120 and $0.30 in the 60, and Pure Encapsulations at $0.34. The two powders have no per-unit figure on file, since a tub is not counted out in advance. All 30 in the category are in stock as of that feed date — the full list sits on our magnesium page.

What is the most trusted brand of magnesium glycinate?

There is no single brand everyone trusts — the ones that move fastest here are the ones whose ingredient list is short enough to read in one breath.

We stock 30 magnesium products across 8 brands: CanPrev, ITL Health, NOW, Naka Platinum, Natural Factors, New Roots, Pure Encapsulations and WomenSense. Pure Encapsulations has the reputation among shoppers who care most about what is not in the capsule. New Roots and ITL Health are the two that repeat-buyers keep coming back for once price enters the picture. Trust, on this shelf, mostly comes down to whether the same bottle is still working for you a year later.

Is Pure Encapsulations of magnesium glycinate any good?

Yes — and the thing it does that the cheaper bottles do not is give you 180 capsules in one container.

At $60.50 it is the highest sticker price we feature, but at $0.34 a capsule it sits $0.07 above New Roots' 120-count and $0.15 above the ITL Health 120. That is the whole gap, and for a household emptying a bottle in six weeks it is a few dollars a month. What you are buying alongside the magnesium is the count: fewer reorders, fewer part-used bottles at the back of the cupboard, one line item instead of three.

Why does Pure Encapsulations magnesium cost more?

Partly the pack size, partly the formulation standard the brand builds to — and the pack size is the part you can check yourself.

• $60.50 for 180 = $0.34 each
• $32.49 for 120 = $0.27 each
• $22.99 for 120 = $0.19 each
• $12.99 for 60 = $0.22 each

Compare sticker to sticker and the gap looks enormous; compare per capsule and it narrows to pennies. The brand also carries a reputation for a tightly controlled excipient list, which is what most people are actually paying the premium for. If cost per capsule is your only measure, the ITL Health bottle wins outright and we will say so.

Magnesium powder or capsules - which should you buy?

Buy the powder if you want to vary the amount you take, the capsules if you want it settled and portable.

• Powder: the 400 g WomenSense tub at $44.99 and the 145 g Natural Factors tub at $19.99. Both need water, a spoon and a minute.
• Capsules: 60, 120 and 180 counts, from $12.99 to $60.50. Nothing to measure, nothing to stir, and they travel in a bag.
• Cost: capsules have a printed per-unit figure; tubs do not, because how far one goes depends on how you scoop it.

In practice the powders go to people already drinking something before bed, and the capsules go to people who take things standing at the kitchen counter. One tub also serves a household at different amounts, which no capsule can do.

When should you take Pure Encapsulations of magnesium glycinate?

At whatever point in the day you will actually repeat tomorrow — consistency beats clever timing.

Most of our customers land on evening, simply because it attaches to an existing habit. Some take it with a meal because capsules go down easier that way. The 180-count matters here: a bottle that outlasts the month is a bottle you are still taking from in week six, and the one you finish is worth more than the one you optimised.

What does magnesium do in the body?

It is an essential mineral involved in a long list of everyday processes rather than any single one.

It works as a cofactor in various enzymatic reactions (1). It is an essential macronutrient for plants as well as for people (2).

What happens if you take magnesium glycinate every day?

For most people daily use is simply topping up what the diet supplies, since magnesium is a nutrient you are meant to take in every day anyway.

Whether daily use fits your own situation is worth putting to your doctor before you buy at the top of the ladder.

What does elemental magnesium mean on a label?

Elemental magnesium is the weight of the magnesium itself, stripped of whatever it is bound to.

Magnesium never arrives on its own — it is always attached to something, glycine in this case, and that partner has weight of its own. So a capsule described as 200 mg elemental contains 200 mg of magnesium plus the considerably heavier compound carrying it, while a bottle quoting the compound weight is quoting a bigger number for less magnesium. Read the elemental figure and the two bottles become comparable. The oxide carries the highest magnesium content and the lowest organic content (3).

FAQ

Is magnesium bisglycinate the same as magnesium glycinate?

Yes. Both names describe magnesium bound to the amino acid glycine; "bis" just points to the two glycine molecules attached to each magnesium ion, which is the standard arrangement either way. Magnesium bisglycinate has shown the sharp peaks characteristic of crystalline magnesium formulations (3).

What is the purest form of magnesium glycinate?

There is no official purity grade, so the useful question is what else is in the capsule. A glycinate that lists glycinate as its only magnesium source is a different thing from one blended with an inorganic magnesium salt to raise the milligram number, and the ingredient list is where that shows.

What does fully reacted mean on a magnesium bottle?

It means the magnesium has been fully bound to glycine during manufacture, rather than mixed with a portion of unbound mineral salt afterwards. The phrase exists because blends of the two do circulate, and the two are not equivalent on the spoon.
