The Best Creatine in the UK
This is the easiest shelf on the site to shop, because the answer is largely settled. Creatine monohydrate is the form with the research behind it, and it's chemically identical whoever sells it, so a premium tub doesn't contain a better molecule. That leaves three things to compare: cost per 5g serving, how well it dissolves, and whether the pack size matches how long you'll keep taking it. Everything below is plain monohydrate. Hydrochloride, ethyl ester and the various advanced blends are absent because none has evidence of beating it.
Ranked by real ratings · updated 25 September 2026 · how we rank
On the ratings data the strongest creatine we track is Nutricost Creatine Monohydrate Micronized Powder 500G, 5000mg, on 4.7 out of 5 from 49,400 ratings. If you want to spend less, Myprotein Impact Creatine Monohydrate Powder | 250 sits at the cheaper end and still rates at or above the middle of the shelf. Neither is a paid placement, and the full working is below.
Myprotein Impact Creatine Monohydrate Powder | 250 g | Micronised
Micronised monohydrate at under £8 for 250g, which is around 50 servings and works out at roughly 16p a day. Myprotein is a large UK operation with the volume to price this low. If you're starting creatine and not sure you'll stick with it, start here rather than with a kilo.

Nutricost Creatine Monohydrate Micronized Powder 500G, 5000mg Per Serv (5g)
500g of micronised monohydrate with 48,300 ratings at 4.7, which is one of the largest and most consistent review bases in our entire catalogue. Micronised means it dissolves more easily and grits less, which is a texture benefit rather than a potency one, and it's the complaint people actually have about creatine.

Bulk Creatine Monohydrate Powder, Pure Unflavoured, 1 kg
A full kilo, unflavoured, which is around 200 servings or most of a year at 5g a day. Creatine is stable in a sealed tub, so buying long is sensible here in a way it's not for everything. Work out the per-serving cost against the 500g tubs before assuming the kilo wins.

Optimum Nutrition Micronised Creatine Monohydrate Powder, 317g | Unflavoured, 93 Servings
Optimum Nutrition is the name most people in a gym recognise, and 21,200 ratings at 4.6 says it delivers. You are paying a modest premium over own-label for consistency and availability rather than for a different compound.

Warrior Creatine Monohydrate Powder 1kg
1kg advertised as 333 servings, which is a year and then some. The practical case for a year pack is that creatine works by saturation and consistency, so running out mid-way is the main reason people lose the effect they built.

THORNE Creatine, 450g (90 Servings) | Monohydrate Powder, NSF Certified
Thorne test to NSF Certified for Sport standards, which matters if you compete in a tested sport and need assurance against contamination. For everyone else it's a premium you don't need to pay, and we wouldn't pretend otherwise.
