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 13 2026)

January sale season is still in full swing, but this week the UK table finally moved in a meaningful way, with one clear price drop reshuffling the top of the index. The US market remains mostly steady.

Best value this week

UK

Bulk Creatine Monohydrate is now the best value in the UK index at £19.99 per kg (£2.00 per 100g / £0.10 per 5g), down 20% week-on-week. That’s a big enough move to overtake Myprotein on pure cost-per-gram.

Myprotein Impact Creatine stays at £22.99 per 1kg (£2.30 per 100g / £0.11 per 5g) with no change this week, but it remains one of the strongest value benchmarks in the index.

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.

Biggest changes

• UK

  • Bulk: £19.99/kg (−20.00%) — the biggest movement in the UK index and the reason the “best value” crown changed hands. There’s also a separate Amazon deal currently showing −19% (£10.99 for 500g).

  • Warrior: £14.99 for 500g (−1.06%), keeping it competitive in the mid-range.

  • Bio-Synergy: £45.00 for 500g (−12.34%), a meaningful drop vs last week and now noticeably cheaper than its previous pricing.

    (Meanwhile, Optimum Nutrition and ESN show no base price change, but both have strong Amazon discounts: Optimum −40% (£24) and ESN −41% (£14.89).)

• US

  • No major price movements this week across the tracked products. The only notable difference is Thorne, where Amazon is currently listing it at $82 (about $2 less than the on-page listing price of $84).

One insight

This week is a perfect example of why your index is useful: a single real price cut beats a dozen “limited-time deal” banners.

The UK market is full of discount messaging right now, but the only change that truly matters long-term is when a product’s cost per gram actually drops enough to change the rankings, like Bulk did this week. Everything else is noise until it affects the underlying numbers.

What to watch next week

• Whether Bulk holds £19.99/kg or snaps back upward once the promo period ends

• If the Optimum / ESN Amazon discounts stay live or vanish without warning

• Whether US pricing finally moves, since it often lags UK sale activity by a week or two

  Next update should tell us if this is a genuine “new floor” for UK creatine pricing or just a short-lived January spike in competitiveness.

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.

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.

Is this purchasing or medical advice?

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