Chromium in Berberine Supplements: What It Means
Our formula supplies 50 µg of chromium as chromium picolinate, 125% of the NRV, and chromium is the ingredient here that carries authorised EU health claims.
Chromium is a trace mineral found in everyday food. In our formula it is present as chromium picolinate, 50 µg per daily serving of two capsules, which is 125% of the EU nutrient reference value. Two authorised EU health claims belong to chromium: chromium contributes to normal macronutrient metabolism, and chromium contributes to the maintenance of normal blood glucose levels.
Key takeaways
- Our daily serving supplies 50 µg of chromium as chromium picolinate, which is 125% of the 40 µg nutrient reference value (NRV).
- Two health claims are authorised in the EU for chromium: "Chromium contributes to normal macronutrient metabolism" and "Chromium contributes to the maintenance of normal blood glucose levels". Both belong to chromium as a nutrient.
- A product may only use those claims if it is a source of chromium, meaning at least 6 µg per daily portion. That is a quick and genuinely useful check to run on any label.
- Supplement chromium is trivalent chromium, chromium (III), the form found in food. It is a different substance from the hexavalent chromium associated with industry.
- Chromium picolinate is one of the chromium forms permitted in food supplements under Irish and EU law.

What chromium actually is
Chromium is a metallic element that turns up in small amounts in ordinary food. Wholegrains, meat, nuts, broccoli and some fruit all contribute a little to a normal diet. Because the amounts involved are tiny, chromium is declared on labels in micrograms (µg), thousandths of a milligram.
That unit is worth pausing on. A berberine capsule contains hundreds of milligrams of berberine HCl and only tens of micrograms of chromium. The two figures sit on the same panel and differ by a factor of thousands, which catches people out at first glance.
One distinction matters more than any other, and it is a reassuring one. The chromium used in food supplements is trivalent chromium, chromium (III), the form present in food. Hexavalent chromium, chromium (VI), is the industrial form associated with occupational harm, and it has no place in food and is not permitted in supplements. When a supplement label says chromium, it means the trivalent form, and the specific compounds allowed are set out in law.
What is in our formula, and why
Our daily serving of two capsules supplies:
| Item | Detail |
|---|---|
| Form used | Chromium picolinate (a permitted trivalent chromium form) |
| Amount per daily serving | 50 µg chromium |
| Nutrient reference value (NRV) | 40 µg |
| % NRV per daily serving | 125% |
| "Source of" threshold (15% NRV) | 6 µg, comfortably exceeded |
Chromium is in the formula as a declared nutrient in its own right, at a level that sits above the NRV and well above the legal threshold for using a chromium claim. It is also the ingredient here that carries authorised EU health claims, which is why it appears on the front of so many packs across the category.
One point of housekeeping so nothing is blurred: the claims below belong to chromium as a nutrient. They are not statements about berberine, which carries no authorised EU claim of its own, and they cannot be transferred to it or to the product as a whole. You can see the full ingredient and serving information for the rest of the panel.
The two authorised claims for chromium
Under Regulation (EC) No 1924/2006, a health claim may only be used on a food in the EU if it appears as authorised on the EU Register of nutrition and health claims. Chromium has two:
"Chromium contributes to normal macronutrient metabolism"
"Chromium contributes to the maintenance of normal blood glucose levels"
Both are used here in full, word for word, which is how they are meant to be used. Two details are worth knowing if you compare packs.
The word "normal" is part of the claim. It cannot be dropped or swapped. It describes the maintenance of ordinary function in a healthy person. A wording that removes it, or upgrades "maintenance" into "control", is no longer the authorised claim.
The claim names chromium. FSAI guidance is clear that a claim must keep a clear link between the nutrient and the claimed effect, so it stays attached to chromium rather than to a brand name or a formula.
| Wording | Status | Why |
|---|---|---|
| "Chromium contributes to normal macronutrient metabolism" | Authorised | Exact wording, nutrient named, "normal" retained |
| "Contains chromium, which contributes to the maintenance of normal blood glucose levels" | Acceptable form | Nutrient and effect stay clearly linked |
| "Our formula contributes to the maintenance of normal blood glucose levels" | Not acceptable | Credits the product rather than chromium |
| "Chromium contributes to blood glucose control" | Not acceptable | "Normal" removed, and "control" goes beyond maintenance |
The 6 µg check, worked through
An authorised claim comes with a condition of use, and for a mineral it is simple: the product must at least be a source of that mineral. "Source of" means 15% of the nutrient reference value in the recommended daily portion. Chromium's NRV is 40 µg, so:
40 µg × 15% = 6 µg per daily portion
That single number is a handy buying check. If a pack prints a chromium claim, the daily portion has to deliver at least 6 µg. If the declared amount is lower than that, or if no amount is declared at all, something is off and it is fair to ask the seller why.
| Chromium per daily portion | % NRV | Source of chromium? | Claim permitted? |
|---|---|---|---|
| 3 µg | 7.5% | No | No |
| 6 µg | 15% | Yes, exactly at the threshold | Yes |
| 20 µg | 50% | Yes | Yes |
| 50 µg (our serving) | 125% | Yes | Yes |
Read the threshold for what it is. It sets the floor for using the wording, so it tells you a pack is playing by the rules. It is not a scale where a bigger number is automatically better, and no label should be read that way.
Which chromium forms are permitted
Only named chemical forms of a mineral may be used in food supplements. For chromium, Annex I of the FSAI's Guidance Note 21 lists chromium (III) chloride, chromium (III) lactate trihydrate, chromium nitrate, chromium picolinate and chromium (III) sulphate. All are trivalent forms. Chromium picolinate, the form we use, is the one seen most often on Irish shelves. A compound outside that list is a fair question to put to a seller.
What to check on any chromium label
- Is a chromium amount declared in micrograms per recommended daily portion, not just per capsule?
- Is a % NRV shown beside it, calculated against 40 µg?
- Does the daily portion supply at least 6 µg, the minimum for a chromium claim to be used?
- Is the chromium form named, and is it one of the permitted trivalent forms?
- If a claim is printed, is it word for word one of the two authorised chromium claims, with "normal" kept in?
- Is that claim sitting next to chromium rather than next to a brand name?
- Does anything on the pack suggest an effect on a disease? That is never permitted on a food supplement.
The same habits apply to the rest of the panel. Our guides to reading a food supplement label in Ireland, choosing a berberine supplement in Ireland and black pepper and piperine in supplements cover the other lines you will meet.
Frequently asked questions
How much chromium is in your product?
The daily serving of two capsules supplies 50 µg of chromium, as chromium picolinate. Against the EU nutrient reference value of 40 µg, that is 125% NRV. The figure is printed on the bottle beside the % NRV, and the physical label is always the version to go by. That level is well above the 6 µg minimum required before a chromium claim may be used.
What does % NRV mean?
NRV stands for nutrient reference value, a single labelling benchmark used across the EU so shoppers can compare products on the same basis. For chromium the NRV is 40 µg, so a serving of 50 µg shows as 125% NRV and a serving of 20 µg shows as 50%. It is a comparison reference for labelling, not a personal target you need to reach.
What can be said about chromium, exactly?
Two wordings are authorised in the EU: "Chromium contributes to normal macronutrient metabolism" and "Chromium contributes to the maintenance of normal blood glucose levels". Both belong to chromium as a nutrient and both keep the word "normal". They describe chromium's contribution and nothing else in the capsule, so they should always appear beside chromium rather than beside a product name.
Is the chromium in supplements the same as the chromium in industry?
No. Food supplements use trivalent chromium, chromium (III), and only in the compounds permitted by law, such as the chromium picolinate used here. The chromium associated with occupational harm is hexavalent chromium, chromium (VI), a different chemical species that is not permitted in food at all. The permitted supplement forms are listed in FSAI Guidance Note 21.
Why is chromium picolinate used rather than another form?
Chromium picolinate is one of the trivalent chromium compounds permitted in food supplements under Irish and EU rules, and it is the form most commonly used in the category. It is a stable, well characterised material that can be dosed accurately and tested against a specification, which is what you want from a nutrient declared in micrograms.
Should I take a separate chromium supplement as well?
Check what you are already getting before adding more. Chromium occurs in ordinary foods including wholegrains, meat, nuts and broccoli, and our serving already provides 125% NRV. Stacking products that contain the same mineral is how people quietly go past sensible intakes. Add up the daily total across everything you take, do not exceed the stated dose on any label, and ask your pharmacist if you are unsure.
Does a higher % NRV mean a better product?
Not by itself. The 6 µg "source of" threshold is a floor that allows a chromium claim to be used, and going far beyond it does not make a label better. What is worth checking is that the amount is declared clearly per daily portion, that the % NRV is shown, that the form is a permitted trivalent one, and that any claim is the authorised wording.
