Why Daiso supplements made headlines
Daiso is a hugely popular discount variety store chain in Korea. On February 24, 2025, it began selling about 30 health functional foods (Korea's regulated category of dietary supplements) from Daewoong Pharmaceutical, Chong Kun Dang Health, and Ilyang Pharmaceutical at KRW 3,000–5,000 in about 200 stores nationwide. As more stores and drugmakers joined, interest grew quickly thanks to the low prices. Rather than choosing on price alone, though, it is important to know how ingredients and doses differ from product to product. This page groups the supplements you can buy at Daiso Korea by type and compares the products. It is useful if you live in Korea, are visiting, or are curious about the Korean supplement market.
How to choose a Daiso supplement
Cheap does not automatically mean good. Always read the label to check that the ingredient you need is there in a meaningful amount, and that it does not overlap with other supplements you already take. If you have a medical condition or take several medications, it is safest to talk to a doctor or pharmacist before starting anything new.
Amounts at a glance
Amounts per daily serving for popular Daiso supplements. We separate values shown directly by the seller (such as Daiso Mall listings) from values reported by others (press reports or blog ingredient lists, i.e., secondary sources). Products are reformulated from time to time, so always check the label before buying.

Reading the table
- Vitamin D 4,000 IU equals the upper limit (100 µg) in the Dietary Reference Intakes for Koreans. Magnesium and calcium products and multivitamins also contain vitamin D, so combining them can exceed the limit.
- Taking both magnesium products gives 315 mg + 105 mg = 420 mg, above the 350 mg upper limit for magnesium from supplements.
- Omega-3 at 500 mg meets the minimum for the MFDS "blood triglycerides and circulation" claim, but not the dry-eye threshold (600 mg or more).
- "Not confirmed" means the maker or seller has not published the amount, or sources disagree. Check the nutrition and function panel on the pack in store.
Fitness gear worth a look, too
In April 2026, Daiso Korea launched about 60 running clothes and accessories with the sports brand HEAD, and home-workout tools such as foam rollers (KRW 5,000 for 45 cm) and massage balls (from KRW 1,000) are steady sellers. Regular exercise matters as much as any supplement, so we have also covered what is worth buying and how to use it safely.
