Do rugby players take creatine?

Key takeaways

Do rugby players use it?

Widely, at every level, and it is among the most researched supplements in sport.

What can it claim?

That it increases physical performance in successive bursts of short term high intensity exercise, at a daily intake of 3g.

Is it banned?

No. Creatine is not a prohibited substance, though multi ingredient products containing it carry contamination risk.

Does this site sell it?

No. Futuro Labs does not make a creatine product and no other supplement brand is named here.

Why this page has nothing to sell

Futuro Labs does not make a creatine product and this site does not name other supplement brands, so there is no recommendation at the end of this page.

That is worth saying at the top, because it means the assessment here can be plainer than most. Creatine has the strongest evidence base and the strongest authorised claim of anything discussed on this site, and it is not a Futuro Labs product.

The claim, in full

Creatine increases physical performance in successive bursts of short term high intensity exercise, with the effect obtained at a daily intake of 3g of creatine.

For rugby that is an unusually well matched claim. Successive bursts of short term high intensity effort is a reasonable description of what the game asks for, and it is one of very few authorised performance claims that exists in any category. Compare it to magnesium, which contributes to normal muscle function, or collagen, which claims nothing at all.

Monohydrate, and the forms sold at a premium

Creatine monohydrate is the form the research was done on and it is the cheapest on the shelf. Hydrochloride, ethyl ester, buffered and micronised versions are all sold at a premium on absorption or tolerability arguments.

None of those carries a distinct authorised claim. The claim attaches to creatine at 3g a day, and a player paying more for a form is buying the positioning rather than a different regulated status.

The water retention question

The most common reason a rugby player stops is the weight that appears in the first weeks, and it deserves an explanation rather than a dismissal.

Creatine draws water into muscle cells, and one to two kilograms of gain is normal and expected. It is intracellular water rather than fat and it is not the bloating players associate with the word. For a forward that is usually irrelevant or welcome. For a winger watching sprint times it is a real trade off against a modest performance claim, and worth deciding deliberately.

Loading, and whether it matters

Loading protocols use around 20g a day for five to seven days before dropping to a maintenance dose. They bring saturation forward rather than raising the endpoint.

Taking 3g a day from the start reaches the same saturation over three to four weeks without the gastrointestinal discomfort loading sometimes produces. For a club player starting in pre season, the slower route arrives in plenty of time and is easier to keep to.

The contamination point

Creatine monohydrate on its own is a single ingredient product and sits at the lower risk end alongside a mineral or an oil. Creatine inside a multi ingredient pre workout is an entirely different proposition.

Any player who could be tested should use batch certified products across the board. Futuro Labs Magnesium Glycinate is independently lab tested for purity and is not batch certified for sport, and the same applies to Futuro Labs Omega 3 Fish Oil, Futuro Labs Marine Collagen and Futuro Labs Lion's Mane.

Where it sits against everything else

If a club player is building a short list on claim strength, creatine sits at the top on the strength of its authorised claim, ahead of magnesium, omega 3, collagen and lion's mane in that order.

That ordering is not what this site sells and it is what the register says. Futuro Labs Magnesium Glycinate at 22p a day has the fullest claim set of the four products covered here, and creatine has a performance claim none of them has.

Who it suits least

Two groups have a genuine reason to think twice, and neither is about safety in a healthy adult.

Players managing weight for a position or a level may not want one to two kilograms of water. That is a real trade off against a modest performance claim and it is a judgement rather than a warning.

And anyone with kidney problems, or on medication affecting kidney function, should raise it with a GP before starting. Creatine is well tolerated in healthy adults and that is a different statement from it being appropriate for everyone. As with everything on this site, a prescribing clinician is the right person to ask rather than a supplement page.
