Creatine Price Index (updated weekly)

The Creatine Price Index tracks the real cost of creatine supplements across major brands and retailers, using a standardised cost-per-gram approach. Updated weekly, this index compares popular creatine monohydrate products so athletes, lifters, and everyday trainees can see what creatine actually costs, without marketing spin, confusing discounts, or inflated pricing.

This Week’s Creatine Price Update

Best value this week (March 28 2026)

The market now looks very different from the January sale period. In the UK, the deepest discounts have faded and pricing has normalised upward — but one interesting change this week is that Bulk and Myprotein are now tied on cost per gram. In the US, the table moved more meaningfully, with sharper price cuts improving value across multiple brands.

Best value this week

UK

In the UK, Bulk Creatine Monohydrate and Myprotein Impact Creatine are now joint best value, both priced at £24.99 per 1kg (£2.50 per 100g / £0.13 per 5g).

That tie comes from two different directions:

• Bulk has risen sharply from its January low, up 42.88% week-on-week from the last tracked update.

• Myprotein has edged slightly lower to £24.99, down 1.96%.

So while both now sit at the same cost-per-gram, the underlying story is different: Bulk has lost its ultra-cheap January edge, while Myprotein has become slightly more competitive again.

Bio-Synergy also moved higher, reaching £51.30 for 500g (£10.26 per 100g / £0.51 per 5g), which keeps it firmly in premium territory.

US

In the US, Optimum Nutrition Micronized Creatine remains the best value in the index at $46.99 for 1200g ($3.92 per 100g / $0.20 per 5g), down 12.97%. That’s a strong value move and keeps it clearly ahead of the rest of the field on pure cost-per-gram.

Biggest changes

• UK

  • Bulk: £24.99/kg (+42.88%) — the biggest UK move, and a clear reversal from the aggressive January pricing.

  • Myprotein: £24.99/kg (−1.96%) — a modest improvement that brings it level with Bulk on value.

  • Bio-Synergy: £51.30/500g (+2.62%) — another move upward, widening the gap between premium formulations and baseline monohydrate pricing.

  (Meanwhile, Optimum Nutrition still shows no base price change, but Amazon is currently listing it at £24.99, while ESN remains unchanged with a steep −49% / £14.89 Amazon discount.)

• US

  • MuscleTech: $17.39/400g (−25.01%) — the biggest move in the US table this week, making it much more competitive in the mid-range.

  • Nutricost: $43.97/1kg (−6.39%) — a useful drop that keeps it close behind Optimum Nutrition on value.

  • Optimum Nutrition: $46.99/1200g (−12.97%) — a meaningful decline that strengthens its position as the best-value US product.

  All other tracked US products held steady.

One insight

The UK and US markets are telling two different stories right now.

In the UK, January’s standout discounts have mostly washed out, and pricing has settled into a tighter cluster — with Bulk and Myprotein now effectively tied at the top. That suggests the market is no longer being driven by temporary sale spikes, but by more stable retail pricing.

In the US, the opposite is happening: a few meaningful downward moves are improving real value at the lower and mid-range end of the market. In other words, the UK is stabilising, while the US is getting more competitive.

That’s exactly why tracking price per gram over time matters more than one-off discount labels: you’re not just seeing what’s “on sale,” you’re seeing how the market is actually behaving.

What to watch next week

• Whether Bulk stays at £24.99/kg or drifts further upward now that January-level pricing is long gone

• Whether Myprotein undercuts Bulk and reclaims sole best-value status

• Whether the Optimum Nutrition UK Amazon price (£24.99) becomes the new normal or disappears

• Whether the US price cuts on Optimum, Nutricost and MuscleTech hold — or prove temporary

Next update should show whether the UK has entered a more stable spring pricing range, and whether the US is in the middle of a more competitive reset.

How the Creatine Price Index Works

Cost per gram

All products are standardised using a cost-per-gram and cost-per-serving (5g) approach. This removes the impact of tub size, packaging, or marketing claims and allows like-for-like comparison.

What’s included

The index focuses on unflavoured creatine monohydrate products from major brands. Prices are based on the listed product cost at the time of checking and exclude personalised discount codes or short-term flash sales where possible.

Update frequency

Prices are checked and updated weekly on a consistent schedule. This allows meaningful tracking of price movements over time rather than reacting to daily fluctuations.

Don't forget to see our full guide about how the Creatine Price Index works.

Price alone shouldn’t drive the decision. Understanding cost per gram is useful, but it’s only one factor when deciding whether to take creatine, alongside safety, dosage, and whether it actually fits your needs.

Frequently asked questions

Why do creatine prices vary so much?

Creatine prices vary due to branding, marketing spend, flavouring, packaging size, and distribution costs. When products use creatine monohydrate, the active ingredient is chemically identical, so higher prices do not necessarily reflect higher effectiveness.

Are Amazon prices used for the Creatine Price Index?

No. Prices are tracked independently. Retailer links, including Amazon, are provided only as a convenience for readers who wish to view or purchase a product.

Is cheaper creatine lower quality?

Not necessarily. For creatine monohydrate, lower prices usually reflect reduced branding or marketing costs rather than differences in purity or performance.

How often will price changes appear?

Price movement indicators appear once at least two weekly data points are available. Early weeks focus on establishing a reliable baseline.

Why doesn’t the price always match retailer checkout prices?

Retailer prices can change due to promotions, stock levels, or dynamic pricing. The index reflects the price at the time of checking and is intended to show relative value, not real-time checkout pricing.

No. The Creatine Price Index is informational only and does not replace professional dietary or medical advice.
