Magnesium after a rugby match

By Tom Francis·Updated 2026-09-03·3 sources·Editorial policy

Why the post match window does not apply here

The idea of a post match window comes from fuelling and fluid, where replacing what was lost promptly genuinely does matter, particularly with another fixture or session close behind.

Magnesium does not work that way. Most body magnesium sits in bone and inside cells, and circulating levels are tightly regulated. A serving taken in the changing room does not restock a muscle in a way a player would notice, and no authorised claim describes it doing so.

What the post match hour is actually for

Fluid first, and more of it than most players take. Then food, because a player who eats nothing until nine o'clock has lost the most useful part of the evening.

Sodium matters here more than magnesium, because sodium is what sweat is mostly made of after water. An ordinary meal with normal salt in it does that job for most club players without anything bought specially.

Where the daily serving fits

Anywhere consistent, and Futuro Labs Magnesium Glycinate is a two capsule serving that attaches easily to an existing habit. A player who takes their serving with breakfast every day is better served than one who takes it after matches and forgets on the other six days.

Futuro Labs Magnesium Glycinate is a two capsule serving providing 300mg of elemental magnesium, 80 percent of the 375mg reference value, at 22p a day. The value is in taking it 200 times a season rather than in taking it at any particular moment.

The alcohol question

A large share of club rugby involves a drink after the match, and players ask whether magnesium helps with that. It does not, and there is no authorised claim connecting any supplement to alcohol.

Alcohol increases fluid loss and disrupts sleep, both of which work against everything the post match hour was for. That is worth stating plainly rather than selling a capsule into it.

Two matches in a week

Where a club has a cup fixture midweek, or a university player has Wednesday and Saturday games, the post match period genuinely compresses.

That raises the importance of fluid, food and sleep and does not change the magnesium position at all. One serving a day, taken consistently, remains the whole recommendation.

The Sunday and Monday problem

Most club players think about the hour after a match and ignore the two days that follow, which is the wrong way round.

Sunday is where under eating actually happens. A player who has had a heavy Saturday evening tends to eat one poor meal on Sunday and arrive at Tuesday training having replaced very little. Monday is where sleep can be recovered and usually is not.

Those two days shape how Tuesday feels far more than anything taken in a changing room. The magnesium position across them is unchanged: one serving a day, taken at whatever consistent point survives a weekend. Futuro Labs Magnesium Glycinate is 300mg of elemental magnesium at 22p a day, on a Sunday exactly as on a Wednesday, and attaching it to breakfast rather than to training is what makes that true.

What a good post match hour actually looks like

Set out as a sequence rather than a principle, because the principle is easy to agree with and hard to act on at five o'clock on a Saturday.

Something to drink immediately, and more of it than feels necessary. Something to eat within the hour, even if the proper meal is later, because the gap between the final whistle and food is where most club players lose the evening. A normal amount of salt with that food, which covers the sodium question for almost everyone without buying anything.

Then the ordinary daily serving at whatever point it normally happens. Futuro Labs Magnesium Glycinate is two capsules providing 300mg of elemental magnesium at 22p a day, and it belongs in that sequence only in the sense that Saturday is one of the days it gets taken.
