The Supplement Cost Analyzer is a 100% browser-based price comparison calculator that reveals, in plain numbers, the real cost competitiveness hidden behind differences in how manufacturers label their products. Two products at the same price can have very different real costs if one requires more capsules per serving. This tool takes the product price, total capsules in the bottle, capsules per serving, active ingredient per serving (mg), and total capsule weight per serving (mg), and computes three key metrics in real time: total days of supply, true cost per day, and price per 1,000mg of active ingredient. Every ingredient field is entered exactly as written on the label per serving size, so you never have to do any division yourself, and purity (active ingredient ÷ total capsule weight × 100) is calculated accurately regardless of the capsule count. Enter Products A and B side by side and a left-right symmetric gauge shows at a glance which one is cheaper, declaring the true value winner based on the price per 1,000mg. It is useful for objectively verifying whether an overseas direct-purchase deal or a community sale is actually a good price. Note that this is a price comparison calculator only; factors like absorption rate and ingredient form are for you to judge.
Common Use Cases
💊
Decode Direct-Purchase Deals
Filter out products that look cheap but require 3 capsules per serving and are actually expensive, judging true value by price per 1,000mg of active ingredient.
⚖️
Compare Switching Brands
Precisely contrast the price per 1,000mg and purity of your current product against a new candidate to objectively decide whether the price advantage justifies switching.
🛒
Verify Community Sale Deals
Check whether a sale product posted in a deal community is genuinely cheap using cost per day and per 1,000mg, then share the result image with others.
🌎
Dollar ($) Comparison
With both KRW and USD supported, it is optimized for comparing direct-purchase prices on global platforms like Amazon and iHerb within the same currency.
How to Use
1
Pick currency and ingredient type
Choose the currency (KRW/USD) and ingredient type (Omega-3, Vitamin, Other) at the top. The purity warning threshold adjusts automatically to the type, cutting unnecessary warnings.
2
Enter label numbers as-is
Enter price, total capsules, and capsules per serving, then copy the active ingredient and total capsule weight straight from the label per serving size. No separate math needed.
3
Advanced input (optional)
Enter separate EPA and DHA amounts to see an objective ratio type such as EPA-concentrated or Balanced, along with the EPA:DHA ratio. It is a pure classification.
4
Check the winner and purity
Cost per day, per 1,000mg, and purity are compared live in left-right gauges, and a winner card highlights the cheaper product by the per-1,000mg metric. Share the result as an image.
