If you are sourcing supplements from Korea, the first thing worth understanding is that "Korean supplement" is not one category. Korea draws a hard legal line between an ordinary food, a health functional food (건강기능식품, HFF), and a drug. Which side of that line a product sits on determines what claims it can carry, what it must be manufactured under, and which documents you will be able to obtain for your own import registration.
This page explains the framework. It does not recommend products.
| General food (일반식품) | Health functional food (건강기능식품) | Drug (의약품) | |
|---|---|---|---|
| Governing law | Food Sanitation Act | Health Functional Foods Act | Pharmaceutical Affairs Act |
| Regulator | MFDS | MFDS | MFDS |
| Functional claim allowed | No | Yes, within approved wording | Therapeutic claims |
| Approved ingredient list required | No | Yes | Yes |
| GMP manufacturing | Not required | Required | Required |
| Mandatory mark on pack | No | Yes (건강기능식품 mark) | — |
The middle column is the one that matters for supplement sourcing. Products in it are regulated by the Ministry of Food and Drug Safety (식품의약품안전처, MFDS) under a dedicated statute — the Health Functional Foods Act, enacted in 2002 and in force from 2004. Korea was relatively early in giving supplements their own legal category rather than treating them as either food or medicine.
Practical consequence for a buyer: a product carrying the 건강기능식품 mark has an approved functional ingredient, an approved daily intake range, approved claim wording, and a GMP-certified manufacturing site behind it. A Korean "health food" without that mark has none of those things, even if it looks identical on a shelf. When you request documentation from a Korean supplier, this is the distinction to ask about first.
Every functional ingredient in a Korean HFF product got there by one of two routes. Knowing which route applies tells you a great deal about supply, price and exclusivity.
These are ingredients listed in the Korean Health Functional Food Code (건강기능식품 공전) — a published register maintained by MFDS. The Code sets, for each ingredient, the specification, the permitted daily intake range, and the exact functional claim wording that may be used.
Any manufacturer may use a notified ingredient without applying for individual approval, provided the finished product meets the Code specification. Roughly 95 ingredients are listed. Most of the volume categories sit here: vitamins and minerals, omega-3 fatty acids, lutein, milk thistle extract (silymarin), probiotics, coenzyme Q10, red ginseng, and so on.
You are buying on quality, price, documentation and reliability — not on exclusivity.
a stronger claim, and you should treat any supplier who offers to as a red flag.
An ingredient not in the Code can be submitted to MFDS with the applicant's own safety and efficacy dossier. If approved, the applicant alone may use it.
Exclusivity runs for six years from the date of approval, measured from the approval date rather than from first manufacture — a change made in the 2010s that lengthened the protection meaningfully. Transfer into the Code is not automatic at six years: it also requires a track record of item manufacture notifications and approval held by more than one operator. A 2026 bill would write these criteria into the statute itself and add a right to request deferral of up to three further years, so the rules here may tighten again.
supplier offers you an individually approved ingredient, ask whose approval it is and whether they are the approval holder or a licensee.
years, which is reflected in the finished-goods price.
Korean functional claims are graded by strength of evidence, and the permitted wording reflects that grade. Broadly:
(e.g. a vitamin's role in normal metabolism). The weakest, most standardised tier.
bodily function. Wording is hedged and fixed by MFDS.
in only two areas: reduction of osteoporosis risk (calcium, and vitamin D) and reduction of dental caries risk (xylitol). That is the entire list. If a supplier tells you a Korean ingredient carries a disease-risk claim outside those two, the claim is wrong.
Two things follow for an importer. First, the wording is not negotiable — it is attached to the ingredient, not written by the marketer. Second, Korean approved wording does not transfer to your market. An MFDS-approved claim carries no legal weight in Vietnam, Indonesia, the EU or the United States; each authority runs its own claims regime. Plan your destination-market claims from your own regulator's list, not from the Korean label.
Health functional food manufacturing in Korea must take place in a GMP-certified facility. Korea phased the requirement in by manufacturer size — 1 December 2018 for larger producers, 2019 for mid-sized, and 1 December 2020 for the smallest — with a conditional extension for a final group of firms that ran to 1 December 2021. Since then it has applied to every health functional food manufacturer without exception.
GMP is therefore not a differentiator among compliant Korean manufacturers; it is the baseline. Treat its absence as disqualifying rather than its presence as a selling point.
For your import file, ask for the GMP certificate of the actual manufacturing site, not of the brand owner. In Korea the brand company and the factory are frequently different legal entities, which is normal and not a warning sign — but your destination authority will want the site certificate.
Korean-language labelling and advertising for health functional food must be reviewed before publication. Under Article 10 of the Act on Labelling and Advertising of Foods, the review is carried out by a self-regulatory body registered with MFDS — for health functional food, the Korea Health Supplement Association. Where no such body exists, MFDS reviews directly. Straight reproduction of the statutory labelling particulars is exempt; anything beyond that is not.
This is why Korean supplement marketing reads conservatively compared with, say, US marketing. It also means a Korean supplier is used to working within fixed claim wording — useful when you need them to stay inside your own market's limits.
It cuts the other way too: Korean approved copy is often unusable in your market, and your market's aggressive copy would be illegal in Korea. Budget for a local copy rewrite and local regulatory review; do not translate the Korean label.
A Korean HFF supplier should be able to produce all of the following. If any of them causes hesitation, that is your signal.
| Document | Korean name | Issued by | Used for |
|---|---|---|---|
| Certificate of Free Sale | 자유판매증명서 / 판매증명서 | MFDS | Proving the product is legally sold in Korea — required by most importing authorities |
| GMP certificate | GMP 적합인정서 | MFDS | Proving the manufacturing site is certified |
| Certificate of Analysis | 시험성적서 | Accredited lab / manufacturer | Per-lot specification conformity |
| Certificate of Origin | 원산지증명서 | Korea Chamber of Commerce & Industry | Claiming preferential FTA tariff rates |
| Ingredient specification | 원료 규격서 | Manufacturer | Local registration dossiers |
| Health certificate | 위생증명서 | MFDS | Required by some markets at customs |
On the Certificate of Origin: Korea has a wide FTA network, and preferential duty is often the difference between a viable and a non-viable landed cost. Check your country's Korea FTA schedule for the relevant HS code before you finalise pricing — this is one of the most commonly missed items in first-time imports.
The Korean side is only half the problem. The registration route in your own market is usually the longer pole in the schedule.
