Chromium and sugar cravings: what is proven
The short answer: there is no authorised health claim for chromium relating to cravings, appetite or body weight. Three corresponding wordings were assessed and appear in the EU register as "non-authorised". The idea goes back to a single study in people with atypical depression that used 600 µg of chromium a day — more than three times what a usual tablet contains. Anyone standing at the shelf looking for a solution to the evening reach for chocolate will not find it there.
Hardly any trace element is linked as consistently to the wish for less sugar as chromium. The chain of reasoning sounds plausible: chromium has something to do with carbohydrate metabolism, cravings have something to do with sugar, therefore chromium helps against cravings. Between the first and the last link of that chain, however, there is a gap — and it is well documented.
What may appear on the pack — and what may not
Exactly two claims are authorised for chromium in the EU, in the wording of Regulation (EU) No 432/2012:
- Chromium contributes to normal macronutrient metabolism.
- Chromium contributes to the maintenance of normal blood glucose levels.
Whatever else was applied for is listed in the EU register on nutrition and health claims — with a reason attached. Three wordings targeted precisely the subject of this article:
| Claim applied for (original) | Health relationship | Status |
|---|---|---|
| "Promotes carbohydrates catabolism, helping in body weight maintaining" (ID 4665) | contribution to the maintenance or achievement of a normal body weight | non-authorised |
| "Promotes lipid catabolism, helping in body weight maintaining" (ID 4666) | ditto | non-authorised |
| "Promotes metabolism. Supports weight control physiologically" (ID 339) | ditto | non-authorised |
| "Chromium contributes to the maintenance of normal blood glucose levels" (ID 262) | maintenance of normal blood glucose levels | authorised |
The reason given for the rejection is the same for all three weight claims and can be read in the register: the evidence provided was insufficient to substantiate the claimed effect. The basis is the same EFSA opinion from which the authorised blood glucose claim also comes (EFSA Journal 2010;8(10):1732) — the panel assessed both in one go and arrived at two different results.
A word on the term itself: "craving" appears in none of the applications. The applications were always made via body weight. A claim that did not make it onto the list may not appear in a softer version either — "supports you when you fancy something sweet", "helps to control the desire for sugar" and similar paraphrases are legally the same claim.
Where the craving story comes from
The link between chromium and carbohydrate craving has a concrete origin: an eight-week, double-blind, multicentre study from 2005 (Docherty et al., Journal of Psychiatric Practice 11(5):302–314). 113 outpatients with atypical depression received, in a 2:1 ratio, either 600 µg of elemental chromium as chromium picolinate or a placebo.
Three things about it matter, and they usually get lost when it is retold:
- The primary outcome was negative. On the overall depression rating scale (HAM-D-29) there was no significant difference between chromium and placebo; both groups improved markedly compared with baseline.
- The effect showed up on individual items. Four items of the scale came out in favour of chromium: increased appetite, increased eating, carbohydrate craving and diurnal variation of mood. In a subgroup with particularly strong carbohydrate craving, 65 % of the chromium group responded compared with 33 % on placebo.
- The study group is not the shelf group. Those examined were people with a diagnosed illness in which increased appetite is part of the clinical picture. Nothing can be transferred from that to the evening desire for chocolate in an otherwise healthy person — and it is precisely this transfer at which EFSA sees the chain of evidence break.
The authors themselves describe the investigation as exploratory. An exploratory study generates hypotheses; it confirms none.
What the weight studies show
On body weight — the subject under which the applications were submitted — there is considerably more material, and it has been summarised:
| Evaluation | Scope | Result | Authors' assessment |
|---|---|---|---|
| Cochrane review, Tian et al. 2013 (CD010063) | 9 randomised studies, 622 participants, 200–1,000 µg, 8–24 weeks | −1.1 kg compared with placebo after 12–16 weeks (95 % CI −1.7 to −0.4) | "of questionable clinical relevance"; no dose dependency; low quality of evidence |
| Meta-analysis, Tsang et al. 2019 (Clinical Obesity) | 21 evaluations from 19 studies, 1,316 participants | weight −0.75 kg (95 % CI −1.04 to −0.45); BMI −0.40; body fat percentage −0.68 % | moderate effect size, "clinical relevance remains uncertain" |
Both evaluations look at people with overweight or obesity over periods of two to six months. In both cases the result is barely a kilogram — and in both cases there is an explicit restriction that no recommendation follows from it. The Cochrane conclusion is the clearest sentence on the subject: there is no reliable evidence on which to decide dependably about the effectiveness and safety of chromium picolinate in overweight adults. Only three of the nine studies reported any data on adverse events at all.
Also striking is what was not found: no relationship between dose and effect. If 1,000 µg does no more than 200 µg, that argues against a dose-dependent mechanism — and in favour of a very small or coincidental finding.
The question of quantity
This is where it becomes practical for the purchasing decision. The study from which the craving narrative comes worked with 600 µg of chromium a day. For comparison, the figures that serve as orientation in Germany:
| Value | Amount | Origin |
|---|---|---|
| Nutrient reference value (label, "% NRV") | 40 µg | Regulation (EU) No 1169/2011, Annex XIII |
| Estimated value for an adequate intake, from 15 years | 30–100 µg/day | D-A-CH, cited after BfR 2021 |
| Proposed maximum level for food supplements | 60 µg per daily portion | BfR 2021 |
| Guidance value for additional intake | 250 µg/day | EFSA 2010, corresponds to the WHO value |
| Dose in the craving study | 600 µg/day | Docherty et al. 2005 |
The 600 µg are therefore far above the value up to which EFSA sees no health concerns. A commercially available preparation does not reach that amount — and a preparation that did would not be a usual case in Germany. Anyone citing the study as a reason for a product is citing a dose that the product does not deliver.
Our Chromium 200 µg contains 200 µg of chromium per tablet as chromium picolinate — the form also used in the studies; the differences between the authorised compounds are set out in Chromium forms compared. This amount is above the BfR proposal of 60 µg and below the EFSA guidance value of 250 µg. Neither of these is a statutory limit: binding European maximum levels for vitamins and minerals in food supplements do not exist to this day.
How reference value, estimated value and guidance value relate to one another, and why three numbers for the same question are in circulation, is set out in detail in How much chromium per day.
What actually drives cravings
If a trace element does not answer the question, it is worth looking at what does. Cravings are not a uniform phenomenon, but the recurring triggers are known and banal:
- Eating too little. Strict diets and long gaps between meals produce exactly the desire they are aimed against.
- Meals that do not satisfy. Quickly available carbohydrates without fibre, protein or fat do not last long. The German Nutrition Society (DGE) states a guideline value for adults of at least 30 g of fibre per day and points to pulses, nuts and seeds, wholegrain products, vegetables and fruit; it explicitly lists the satiating effect as one of the effects of fibre.
- Too little sleep. A sleep deficit shifts eating behaviour the following day — a well-studied relationship, even if its magnitude is debated.
- Habit and situation. Reaching into the drawer at 9 p.m. is often a learned sequence and not a metabolic state.
None of these points can be short-circuited with a tablet, and none of them is a nutrient gap. That is precisely why the question "which supplement helps against cravings?" is hard to answer: in most cases it is addressed to the wrong place.
Chromium remains sensible as what it is — a trace element with two authorised claims about normal metabolism. What the blood glucose claim covers exactly, and why "maintenance" does not mean "lowering", is taken apart in Chromium and blood sugar; which foods provide any noteworthy amount of chromium at all is set out in Chromium in foods. Further trace elements and their reference values can be found in the Minerals category, all chromium products in the Chromium category.
Food supplements are not a substitute for a balanced and varied diet and a healthy lifestyle.
Frequently asked questions
May a chromium product be advertised with cravings or weight loss? No. There is no authorised claim for chromium relating to appetite, cravings or body weight; three applications on the subject appear in the EU register as "non-authorised". Only the two wordings on macronutrient metabolism and on normal blood glucose levels are permitted — and even those only if the product reaches at least 15 % of the reference value per daily portion, that is 6 µg.
But the studies do show one kilogram less — is that nothing? It is an average from studies in people with overweight over two to six months, without any discernible dose dependency, and the authors of both evaluations expressly consider the clinical significance questionable. As proof of an effect on cravings it is no use: weight and desire are two different endpoints.
Is chromium picolinate more effective than other forms? For the question of cravings there is no form with a proven advantage. Chromium picolinate is the compound most frequently used in studies and, according to EFSA, is safe as a source of chromium as long as a total intake of 250 µg per day is not exceeded. That does not mean an advantage in absorption compared with other authorised compounds.
What about chromium for sugar cravings during a diet? There are no reliable indications for that. Anyone struggling with strong cravings while changing their diet will, as things stand today, get further with the structure of their meals — enough protein, enough fibre, no gaps that are too long — than with a trace element.
