A MAL number is the registration number Malaysia’s Drug Control Authority gives a product it has approved. It begins with MAL, then eight digits, then a letter naming the category — N for supplements, T for traditional medicines. Anyone can check one free on the regulator’s public search. Registration covers safety, quality and labelling, not whether the product works.
This page sits in our evidence-literacy work, alongside foundational nutrient status and the pillar guide why am I always tired?. Our other pages end at “should I take this?” This one answers what comes first: has Malaysia approved it, and what did that approval examine?
- The format is fixed. The National Pharmaceutical Regulatory Agency (NPRA) states that "a valid registration number begins with ‘MAL’, followed by 8-digit numbers and ends with an alphabet to indicate their registration category".
- The final letter is a category, not a grade. NPRA’s key: A controlled medicines, X over-the-counter, T traditional, N supplements, H veterinary.
- A supplement need not end in N. Counting the Authority’s published list ourselves: 4,315 of 5,014 health supplements carried N, but 698 carried X.
- Registration does not endorse the marketing. The rules require supplement claims to be "for health maintenance and promotion purpose only" and "not be medicinal or therapeutic in nature".
- No hologram, no registration. NPRA is blunt: "All products without security labeling will be considered as unregistered products."
What is a MAL number, and what do the letters mean?
A MAL number identifies one specific approved product. NPRA states that "every registered drug is given a registration number, which must be printed on its label or package". The structure is MAL, eight digits, then a category letter — NPRA’s own example is MAL20165467AZ. Extra letters may follow, so read the letter immediately after the eight digits.
The category letter is the part most people misread: it looks like a quality mark and is not one. It records which set of rules the product was assessed under. Worth having in front of you, because several widely-shared explainers get one letter wrong — H is veterinary, not homeopathic.
| Final letter | NPRA’s category | Entries we counted on the approved list |
|---|---|---|
| T | Traditional medicines | 13,063 — almost all “natural product” |
| A | Controlled medicines | 7,279 — prescription, new chemical entities, biologics |
| N | Supplements | 4,315 — all health supplements |
| X | Over the counter medicines (OTC) | 2,395 — including 698 health supplements |
| H | Veterinary | 1,019 — all veterinary |
Letter key per NPRA. Counts are our own tally of the Drug Control Authority’s approved-product list, published as open data, updated 8 August 2026.
How do you check a MAL number?
Use the regulator’s own product search, which runs on the QUEST3+ system and is free and open to the public. Type the MAL number or the product name, then confirm three things match the box in your hand: the product name, the registration holder, and that the entry is current.
The search sits at quest3plus.bpfk.gov.my, linked from NPRA’s consumer pages. Three habits make the check meaningful:
- Search the number, not the brand. A name can be imitated; the number is tied to one holder and one formulation.
- Read the holder’s name. If the company on screen is not the company on the box, the number may have been copied from another product.
- Check the hologram. NPRA requires the security label on "all registered pharmaceuticals products, traditional Products and health supplements". It must not cover the product particulars, and the buyer "should be able to locate the security label without having to open the packaging".
The hologram is the physical half of the check: anyone can print a number, but the serialised label is supplied only to licensed manufacturers and importers.
Does a MAL number mean the supplement works?
No, and this is the most common misreading of the label. Registration means the Authority assessed the product against its requirements for safety, quality and labelling before allowing it to be sold. It does not certify that the product will relieve your tiredness, and the rules governing what a supplement may claim are deliberately narrower than the advertising around them.
NPRA states that "a product will be registered only if it satisfies ALL the requirements of the DCA, especially with respect to safety, efficacy and quality of the products". That is a real bar — but the rules size the evidence to the claim: a supplement must "maintain the level of scientific evidence proportional to the type of claims", and its permitted claims are narrow and non-therapeutic.
Malaysia’s Drug Registration Guidance Document sets seven conditions on every supplement claim. The last is the one to remember.
All claims made for health supplements (HS) shall: ... be for health maintenance and promotion purpose only; not be medicinal or therapeutic in nature, such as implied for treatment, cure or prevention of disease. Drug Registration Guidance Document, Third Edition, 12th Revision, July 2026, Appendix 6
The same appendix sorts claims into three tiers — general or nutritional, functional, and disease risk reduction — with required evidence rising as the claim strengthens. One threshold is worth knowing: a claim about a vitamin or mineral needs at least 15 per cent of the Codex Nutrient Reference Value per daily dose. A trace on the ingredient list entitles a product to claim nothing.
Does every health supplement end in “N”?
No. N is the supplement category, but it is not the only letter a supplement can carry. When we counted the Authority’s published list of approved products, 4,315 of the 5,014 entries described as health supplements ended in N, while 698 ended in X, the over-the-counter medicine category. An X on a supplement is not a red flag.
“If it does not end in N it is not a registered supplement” is advice we have seen given confidently. The register does not support it.
How much of a vitamin can a registered supplement contain?
Malaysia sets a maximum daily level for each vitamin and mineral allowed in a registered health supplement. Vitamin D is capped at 1,000 IU a day, vitamin C at 1,000 mg, magnesium at 350 mg and zinc at 15 mg. These are ceilings for what a product may supply, not recommendations for what you personally need.
The full table sits in Appendix 6. The entries most often asked about here:
| Vitamin or mineral | Upper daily limit in a registered health supplement |
|---|---|
| Vitamin D | 1,000 IU |
| Vitamin C | 1,000 mg |
| Vitamin B6 | 100 mg |
| Vitamin B12 | 0.6 mg |
| Folic acid | 0.9 mg |
| Calcium | 1,200 mg |
| Magnesium | 350 mg |
| Iron | 20 mg |
| Zinc | 15 mg |
Per Appendix 6, maximum daily levels for adults. For pre- and antenatal use, as part of a multivitamin and mineral preparation, levels above the 20 mg iron limit may be permitted at the Authority’s discretion.
These ceilings explain something readers often notice: a dose used in a published trial can sit well above what any Malaysian product may supply. Our page on vitamin B-complex and energy works through that gap, and vitamin D in Malaysia covers a nutrient whose cap is often misread.
What if there is no MAL number, or it does not check out?
Treat it as unregistered and do not take it. A product sold in Malaysia as a supplement is required to carry a registration number and a security label; a product missing either has not cleared the assessment those markings represent. Report it to NPRA rather than simply putting it back on the shelf.
A number that once checked out can also stop checking out. The Authority publishes a cancelled-registration list too, holding 1,594 products when we counted it. Registrations end for administrative as well as regulatory reasons, so cancellation alone is not evidence of a problem — it is the reason to check now rather than trust a memory of checking once.
NMN and NAD+ supplements is a case where registration decides much of what is sold locally; melatonin in Malaysia is the opposite — no MAL number at all, because no product is approved here. Our research process and disclosures explain how we weigh evidence.
Frequently asked questions
What does MAL stand for on a supplement box in Malaysia?
It is the prefix of the product’s registration number with Malaysia’s Drug Control Authority. NPRA states that "every registered drug is given a registration number, which must be printed on its label or package" and that "these numbers start with MAL". The full format is MAL, followed by eight digits, followed by a letter indicating the registration category.
What do the letters A, X, T, N and H mean at the end of a MAL number?
They indicate the registration category. NPRA’s published key is: A – controlled medicines; X – over the counter medicines (OTC); T – traditional medicines; N – supplements; H – veterinary. Note that some third-party explainers state H means homeopathic; NPRA’s own FAQ says veterinary, and every H-prefixed entry we counted on the official approved list is described as a veterinary product.
How do I check whether a supplement is registered in Malaysia?
Search the number on NPRA’s public product search, which runs on the QUEST3+ system at quest3plus.bpfk.gov.my and is free to use. Enter the MAL number or product name, then check that the product name and the registration holder on screen match the packaging in front of you. Also look for the hologram security label, which NPRA requires on all registered pharmaceutical products, traditional products and health supplements.
Does a MAL number mean a supplement is proven to work?
No. It means the Drug Control Authority assessed the product against its requirements before approving it for sale. The claims a supplement may then make are tightly bounded: Malaysia’s Drug Registration Guidance Document requires that claims "be for health maintenance and promotion purpose only" and "not be medicinal or therapeutic in nature, such as implied for treatment, cure or prevention of disease". Registration is about the product, not about a promised result.
Can a health supplement have a MAL number that ends in X instead of N?
Yes. When we counted the Drug Control Authority’s published list of approved products, 4,315 of the 5,014 entries described as health supplements ended in N, while 698 ended in X, the over-the-counter category. An X on a supplement is not a sign that something is wrong; the letter records which rules the product was assessed under.
What should I do if a product has no MAL number or hologram?
Do not take it, and report it to NPRA. The regulator states that "all products without security labeling will be considered as unregistered products", and registered products are required to carry both the number and the security label on the packaging. A missing marking means the product has not cleared the assessment those markings stand for.
