Best magnesium for university rugby players

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

Two teams, one body

A lot of university players are turning out midweek for the university and on Saturday for a club. That is two fixtures and often three or four training sessions in a week, in the hardest training environment most of them will ever be in.

It sits on top of a diet built around whatever is cheap, quick and cookable in a shared kitchen. The gap between training load and food quality is wider in university rugby than in almost any other level of the game, which is exactly the situation an intake product addresses.

The student food problem, specifically

Magnesium is concentrated in nuts, seeds, wholegrains, pulses and leafy greens. Those are the foods least likely to be in a student kitchen, and pumpkin seeds are not what anyone is buying with a weekly shop budget on a Sunday night.

The rest of the diet, pasta, white rice, chicken and whatever is on offer, is not magnesium dense. That is a straightforward intake gap rather than a performance claim, and it is the honest reason a student player might take a supplement at all.

The criteria that actually decide it

Ranked. On a student budget, criterion six is doing more work than usual.

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.

At 22p a day it is about 6.75 pounds a month, which is inside any student budget that already stretches to a Wednesday night out.

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.

Exam term

Training drops away, sleep gets worse and the diet usually gets worse with it. The reference intake does not change, and magnesium contributes to normal psychological function and to the reduction of tiredness and fatigue at adequate intake.

Those are authorised claims and they are modest ones about normal function. Nothing here improves exam performance and nothing on this site will suggest it does. Lion's mane, which is what students are usually sold into this gap, has no authorised claim of any kind.

Sharing a tub, and why not to

Student houses share everything, and supplements get shared with the rest of it. It is worth naming the two problems with that.

The first is practical. A tub bought by one person and used by four lasts a quarter as long, which turns a 22p a day product into a reordering problem nobody has budgeted for.

The second matters more. A player who could be tested is responsible for what is in their body under strict liability, and that responsibility does not transfer to whoever bought the tub or decanted it into an unlabelled tub in a shared kitchen. University players are tested. Keeping your own labelled product, in its own packaging, is the whole of the precaution and it costs nothing.

• Best magnesium for club rugby playersThe budget version of the same question.
• Supplements for rugby playersWhat carries a claim across all four products.
