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 (January 20 2026)

January sale season is still driving the market, and this week the UK table moved again — but in a different way than last week. Bulk extended its lead with another meaningful drop, while Myprotein jumped upward as the early-January discount softened. The US side stayed mostly stable, aside from one sharp reversal in the mid-range.

Best value this week

UK

Bulk Creatine Monohydrate remains the best value in the UK index at £17.49 per kg (£1.75 per 100g / £0.09 per 5g), down 12.51% week-on-week. That’s now the clear lowest cost-per-gram in the table, and the first time we’ve tracked UK creatine under £1.80 per 100g in this index.

Myprotein Impact Creatine moved the other way, rising to £25.49 per 1kg (£2.55 per 100g / £0.13 per 5g), up 10.87% week-on-week — a strong sign that the biggest January discount window may be closing.

Bio-Synergy also increased to £49.99 for 500g (£10.00 per 100g / £0.50 per 5g), up 11.09%, widening the gap between “premium” pricing and baseline monohydrate value.

US

In the US, Optimum Nutrition Micronized Creatine remains the best value with no price change, continuing to set the baseline for cost-per-gram comparisons across the market.

Biggest changes

• UK

  • Bulk: £17.49/kg (−12.51%) — the most important movement again this week, reinforcing its #1 position. The price is also price-matched on Amazon, which suggests it’s not just a one-off site discount.

  • Myprotein: £25.49/kg (+10.87%) — a meaningful jump that shifts it away from “best value” territory for now.

  • Bio-Synergy: £49.99/500g (+11.09%) — another move upward, making it less competitive on pure cost-per-gram.

    (Meanwhile, Optimum Nutrition still shows no base price change, but an Amazon deal is currently listed at −45% (£21.99).)

• US

  • MuscleTech: $23.19/400g (+16.12%) — the biggest change on the US side, reversing last week’s cheaper pricing and pushing it back toward the higher end of the mid-range.

    All other tracked US products held steady this week.

One insight

This update shows the two different “sale season” dynamics you have to watch:

1. Real floor moves (Bulk) — when price drops far enough that it resets the baseline cost-per-gram for the whole market.

2. Discount fade-outs (Myprotein) — when early January promos quietly unwind and a product slides back toward its normal pricing.

That’s exactly why tracking cost-per-gram beats tracking banners: you’re watching the numbers move, not the marketing.

What to watch next week

• Whether Bulk holds £17.49/kg or snaps back upward once promo pressure eases

• Whether Myprotein drifts further up — or reintroduces a deal to regain competitiveness

• Whether the US market reacts, since it often lags UK sale activity by 1–2 weeks

• Whether the Optimum Nutrition UK Amazon deal stays live or disappears without warning

Next update should confirm whether Bulk has created a genuine “new floor” for UK creatine pricing — or whether this is the most aggressive point of the January cycle before prices normalize again.

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.
