It's 3 a.m. You're staring at the ceiling, doing math about how many hours are left before the alarm. That's the scene the Magnesium Breakthrough sales page opens with, and I suspect it's familiar to a lot of readers.

Magnesium is one of the first things many people try when sleep gets patchy, and for good reason. It's involved in hundreds of enzyme reactions in the body, plenty of adults eat less of it than recommended, and it has a long history of use for relaxation.

Seven forms instead of one

Most magnesium products pick a single form. Glycinate for a gentle evening dose, citrate for something that moves things along, oxide because it's inexpensive. Magnesium Breakthrough, made by BiOptimizers, takes a different approach and gives you seven.

A serving is two capsules, and a 60-capsule bottle holds 30 servings. Per the current label, each serving provides:

• 500 mg of elemental magnesium, from a 1,701 mg blend of magnesium chelate, bisglycinate, Sucrosomial magnesium, malate, orotate, taurate and citrate

• 2 mg of vitamin B6, as pyridoxal-5-phosphate (the active form)

• 1 mg of manganese

• 10 mg of a humic and fulvic blend

I like seeing the elemental magnesium figure printed so clearly. It's the number that actually matters, and not every brand makes it easy to find.

Why mix them?

The company's idea is that different forms of magnesium reach different parts of the body, so a spread covers more ground. There's a practical upside too. The forms absorb a little differently and sit differently in the stomach, so a mix can feel smoother than a big dose of one type.

A few of the forms have their own fans. Glycinate is the one people most often reach for at night. Malate is popular with morning takers. Taurate pairs the mineral with taurine, an amino acid. Sucrosomial magnesium is a patented, coated form designed with absorption in mind. B6 in its active P5P form is a nice touch, since the two nutrients are often taken together.

How to take it

The label says to take the two capsules with your evening meal. That timing fits the sleep goal, and taking magnesium with food tends to be easier on the stomach.

500 mg is a generous serving. The company itself says that if a higher amount upsets your digestion, you can simply drop a capsule, which is a sensible, flexible way to find your own level. The page also describes a longer "loading" plan with more capsules a day; I'd start with the two-capsule label dose and see how you feel first.

What BiOptimizers says

The company calls this "the most potent oral magnesium you will ever find." It describes magnesium as a key nutrient for handling stress at the cellular level.

What appeals to me is the simple logic. If your diet runs low in magnesium, topping it up is an easy, low-effort step, and the evening routine of two capsules with dinner is about as simple as supplements get.

Prices and the guarantee

• One bottle: $35

• Three bottles: $87, or $29 each

• Five bottles: $136, or $27 each

US shipping is free, and there's a subscribe-and-save option if you'd like it to arrive automatically. For 500 mg of elemental magnesium per serving across seven forms, that's fair value.

BiOptimizers offers a 365-day guarantee. On a single bottle, you can ask for a full refund within a year, minus shipping. On bundles, the company refunds your unopened bottles after you've tried the first one, so a good habit is to keep the extras sealed until you know you're happy.

A good fit if

Magnesium Breakthrough suits someone who thinks their diet might be light on magnesium, wants to see whether it helps them wind down at night, and likes the idea of one product instead of a shelf of different forms. If you already take a multivitamin or another magnesium product, add up the totals first.

One thing to know: 500 mg is above the 350 mg daily upper limit US health authorities set for magnesium from supplements, mainly because of loose stools, so starting with one capsule is perfectly fine. If you have kidney problems or take prescription medication, check with your doctor first, since the kidneys are what clear extra magnesium.

For what it's worth, the evidence for magnesium and sleep looks best in people who were short on it to begin with, and I haven't seen evidence that a seven form blend beats one well absorbed form at the same dose.
