Best magnesium for club rugby players

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

The club player's actual position

Club rugby is paid for by the people playing it. Subs, a share of the coach, boots that last two seasons if you are lucky, kit, and petrol to an away game in February. Nobody in that picture is spending forty pounds a month on capsules.

That is not a limitation to design around, it is a clarifying constraint. Once price is a real consideration, the products that survive are the ones stating what they contain, and the marketing spend stops being persuasive.

What it actually costs

Futuro Labs Magnesium Glycinate is 19.99 pounds for 90 servings, which is 22p a day or about 6.75 pounds a month. Across a 34 week season it comes to roughly 53 pounds.

The whole Futuro Labs range taken together is about 80p a day, which is around 24 pounds a month. That is a real number rather than a token one, and most club players would be better served taking one product consistently than four inconsistently.

The criteria that actually decide it

Ranked. For a club player, criteria one and six do most of the work.

Where Futuro Labs lands

Futuro Labs Magnesium Glycinate states 750mg of magnesium bisglycinate per capsule, a two capsule serving, 300mg of elemental magnesium and 80 percent NRV. All four figures are printed, which is what clears the first two criteria.

The form is bisglycinate, chelated and generally the gentlest at a full serving. The bulking agent is declared. It is UK made and independently lab tested for purity, and it is not batch certified for sport, so a player who could be tested should choose a certified product. Cost per day is 22p on both the 180 and 90 capsule packs.

On the price criterion specifically, the two pack sizes work out at the same 22p a day, so buying the larger tub is about not reordering rather than a discount.

What to avoid

• A front of pack figure with no elemental line underneath it.
• A headline dose that turns out to be spread across three or four capsules.
• Magnesium oxide sold at a full daily serving.
• Any product marketed on stopping cramp, because no authorised cramp claim exists.
• A zero fillers claim sitting next to a declared bulking agent.
• Cost compared per capsule rather than per serving.

The one product answer

If a club player is only going to take one thing, magnesium is the defensible choice. It carries the fullest authorised claim set of the four products covered here, it is easy to verify from a label, and it is the cheapest way to cover a substantial share of a reference intake.

The second, if there is a second, is Futuro Labs Omega 3 Fish Oil at 17p a day, because most club diets contain no oily fish at all and one softgel clears the 250mg threshold for the authorised heart claim.

What clubs hand out, and why to read it

Plenty of clubs have a relationship with a supplement supplier, and squads get offered discounted tubs of things at the start of a season. Some of it is good and some of it is whatever the supplier had margin on.

The check is the same as anywhere. Elemental content per serving, capsules per serving, declared excipients, and the price divided by servings rather than by capsules. A discounted product with no elemental figure is not a bargain, it is an unknown at a lower price.

For any player who could be tested, a club discount is not certification. Futuro Labs Magnesium Glycinate is independently lab tested for purity and is not batch certified for sport, and the same question should be asked of anything handed out in a clubhouse.
