How the products were compared
Only products made in Korea and registered with MFDS were included. A higher dose did not earn extra points by itself. Price was compared only among products with the same daily dose. We also checked registration completeness, the number taken per day, and the price source.
Pack prices can be misleading when quantities differ. We divided pack quantity by the number taken per day to calculate the supply period, then normalized every price to 30 days.
View the scoring details and formula
- Verified official data 25 points. Based on how many of seven official items are confirmed in government records: MFDS registration number, functional claim, daily intake, form, pack quantity, cautions, and active dose.
- 30-day normalized cost 25 points. The lowest 30-day cost within the same dose group sets the benchmark; a lower cost earns a higher score.
- Intake convenience 15 points. Fewer units per day score higher: one a day earns 15, two earn 10, three or more earn 5.
- Label and dose transparency 15 points. A numerically confirmed active dose earns 15, label wording without a number earns 7, none earns 0.
- Seller and price stability 10 points. Official brand stores earn 10, open retail listings 8, other verified sources 5. Out of stock earns 0.
- Comparability of form 10 points. Products matching the comparison's main form group earn 10; minority forms earn 6. This measures comparability, not superiority.
30-day normalized cost: (public regular price + mandatory shipping) ÷ supply days × 30. Member, coupon, and subscription prices are excluded.

What to check before choosing
The listed daily doses were Vitamin C 500 mg. Products in different dose groups were not benchmarked against one another for the price score.
The forms were capsule. One purchase covered about 30 to 30 days, so we used a 30-day cost rather than the price of one pack.
Prices were the public regular prices available without login on 2026-08-06. Member and coupon prices were excluded. Mandatory shipping was added for 3 products.
Check whether a multivitamin or another supplement you already take contains the same ingredient. After narrowing the options with the table, review the MFDS cautions for each product.
This ranking does not assess efficacy or personal suitability. It compares MFDS registration details, intake instructions, and verified prices under the same rules.

- Product-specific official cautions are shown in each product analysis.
