Magnesium Glycinate: The Form Made for Daily Use

Magnesium only helps if you keep taking it, and the form is what makes that easy. Magnesium glycinate is magnesium bound to glycine, an amino acid that helps it sit comfortably in your stomach, so it's the version people stay consistent with instead of abandoning after a rough week.

What it is

Magnesium is an essential mineral involved in normal muscle function, nerve signaling and the way your body turns food into energy, and many adults fall short of it from diet alone. Magnesium glycinate — also labeled bisglycinate — is magnesium bound to two molecules of glycine, a pairing known as a chelate. The same mineral is sold as oxide, citrate and malate too; they deliver magnesium differently and don't all feel the same once you've taken them.

How it works

Because magnesium works behind the scenes in so many routine processes, a shortfall tends to build quietly rather than show up overnight. That's the case for a form you can take daily without a second thought: steady intake does more than the occasional large dose. The glycine it's bound to here is part of why this form has a reputation for being easy on the system.

Why the form & source matter

Glycinate costs more than basic magnesium oxide, and tolerance is the reason. Oxide is poorly absorbed and the form most likely to unsettle digestion, while chelated glycinate is chosen for everyday comfort. When you compare products, the figure that counts is the elemental magnesium per serving — not the larger number on the front, which is usually the weight of the whole compound — along with how many capsules make up that serving, since some only reach their headline amount across three or four.

How Monthlees uses it

Monthlees magnesium glycinate is a single-ingredient capsule with the elemental magnesium stated on the label. The same chelated magnesium also appears as a supporting mineral inside one of the Monthlees formula stacks, for anyone who'd rather take it alongside the rest of their routine. Both give you a known amount and the gentle form, with nothing hidden in a blend.

Frequently asked questions

Why do people choose glycinate?

Tolerance. The chelated, glycine-bound form is generally gentler on digestion than oxide, so it's easier to take every day.

How is it different from citrate or oxide?

Glycinate is bound to glycine and is usually well tolerated. Citrate can loosen stools for some people. Oxide is inexpensive but poorly absorbed.

How much magnesium am I getting?

Read the elemental magnesium per serving rather than the compound weight, and check how many capsules make up a serving.

When do people take it?

Often in the evening, but timing comes down to personal preference.
