SUPPSAVEROne number that makes any two products directly comparable.
Supplement pricing is designed to be confusing. SuppSaver normalises every product to a cost per 100 grams of its primary active ingredient — then ranks purely on that. Here's exactly how, with nothing hidden.
Sticker price tells you almost nothing
A 2 kg bag at $89 might look cheaper than a 1 kg bag at $52 — but if the larger bag has lower protein concentration, you could actually be paying more per gram of what matters.
We divide the product price by its total weight, then adjust for the concentration of the ingredient you're actually buying it for. The result is a single number that makes any two products directly comparable, regardless of bag size, serving size, or brand.
How it works, by category
The active ingredient differs by category, so the normalisation does too. The principle is constant: price divided by the thing you came for.
Checked every day, across every store
We keep track of pricing across 12+ Australian supplement retailers every day. For each product we record the current price, capturing any sale or discount pricing alongside the regular price.
Because we check every day, our price history reflects genuine market movements rather than a single snapshot. When you see a price chart on a product page, that's months of real daily data points — not estimates or extrapolations.
Verified nutrition you can trust
Every product in our catalogue carries a complete nutrition profile — protein, calories, macros, serving sizes, and active-ingredient concentrations — stored as structured data we can compare directly.
Nutrition figures are cross-checked against multiple sources before they're published. Where there's any disagreement on a value, we flag it and use the most consistently reported figure rather than a single outlier.
We also run automated sanity checks: if a product's macros add up to more than 100g per 100g of product — physically impossible — the data is held back for review rather than shown.
The maths doesn’t know who paid
Rankings are purely mathematical. We divide price by active-ingredient content, and the lowest number wins. There is no editorial override, no paid placement, and no way for a brand or retailer to pay to rank higher.
Some links to retailers are affiliate links — including Amazon, where SuppSaver participates in the Amazon Associates program — so we may earn a commission if you buy through one, at no extra cost to you. There is no third-party advertising, and commissions never influence rankings, which are pure $/100g maths. SuppSaver is also supported by voluntary Ko-fi donations.
Nightly price checks, timestamped
We re-check retailer prices nightly, and every store row on a product page shows when that price was last checked (“Updated 5h ago”). A check can occasionally fail — for example when a retailer removes a page, changes their site, or has technical issues — in which case the timestamp will be older. Prices can change between checks, so always confirm the price at the retailer before you buy.
If you spot a discrepancy between SuppSaver and a retailer's site, it's most likely because the price changed since our last check — and you can report it any time.
