How Much Cacao Per Day? What The Figures Actually Say

There is no recommended daily amount of cacao. No UK or EU body has set one, cacao has no reference intake, and this page is not going to invent a number to fill the gap. What exists instead is a set of measured figures that bear on the question from the side: how much alkaloid dark chocolate carries, what intake assessments say about caffeine, where the contaminant limits sit, and what individual packs state as their own daily dose.

The category answers this question badly, usually with a confident "one to two squares" and no source behind it. The useful version is dull. Read the pack, know what the percentage changes, and understand which of the figures below is about a food and which is about a compound.

Why no daily amount exists

Reference intakes get set for nutrients with a known requirement, such as vitamin C or iron. Cacao is a food, not a nutrient, and its composition swings with origin, fermentation, roast and alkalisation. A 2022 review in International Journal of Molecular Sciences by Goya, Kongor and de Pascual-Teresa shows how wide that swing is: alkalisation alone has been reported to remove over 60 per cent of total polyphenols, around 98 per cent of epicatechin in one study, and over 20 per cent of theobromine, with losses rising as alkalisation goes further.

Two bars both labelled 70 per cent can therefore differ substantially in what is actually in them. A daily amount set in grams of chocolate would be measuring the wrong thing.

What the measured content figures say

The most directly useful numbers come from a 2017 analysis in Foods by Sanchez, which measured methylxanthines in 63 chocolates, 46 of them dark, grouped as under 50 per cent cocoa, 50 to 60, 70 to 75 and 80 to 85 per cent. Theobromine ran at 4 to 10 milligrams per gram of dark chocolate, measured by AOAC method 980.14 with HPLC and diode-array detection. Caffeine rose with cocoa percentage, and theobromine sat at roughly ten times the caffeine.

The paper's own worked example is the part worth keeping. To reach 400 mg of caffeine, the figure the European Food Safety Authority describes as not raising safety concerns over a day for healthy adults, you would need 360 to 520 grams of 80 to 85 per cent dark chocolate. For milk chocolate it would be over a kilogram. The author also reports a prospective study of 20,951 people with a mean chocolate intake of 4.6 grams a day, or 7.0 grams a day among people who ate chocolate at all. Actual consumption and the theoretical ceiling are two orders of magnitude apart.

The stated limitation is important: methylxanthine content varied widely between samples because of crop origin, processing and preparation. A range is the honest answer, and any single figure for "dark chocolate" is an average standing in for a spread.

The contaminant ceiling nobody mentions

Higher cocoa percentage means more cocoa solids, and the EU maximum levels for cadmium are banded by exactly that. Commission Regulation (EU) 2023/915, of 25 April 2023, sets the EU maximum levels, and the bands make the trade-off explicit.

The permitted level for a dark chocolate is eight times that for a milk chocolate. That is not a scare; the bands in the regulation are written against total dry cocoa solids content, so the permitted level rises as the stated cocoa content does. These are EU maximum levels rather than a guidance figure for eaters, and a product sold at or below the limit is a compliant product. What it tells you is that "more cocoa" is a composition decision with more than one axis.

It is also why a batch test result is worth more than a percentage on a wrapper. Few makers publish one. For the adjacent question, see our note on where the upper end of cacao intake sits.

What packs state, including ours

A food supplement or functional food states its own daily amount, and that is the instruction that applies to the thing you have bought. Chaski's, printed on the tube, is four buttons. It is a daily amount, not a schedule and not a recommendation for cacao in general.

For drinking preparations the conventions are different again, usually measured in grams of paste or powder per cup rather than in pieces; the ceremonial cacao dosage guide covers those. If the alkaloid side is what prompted the question, our note on theobromine and caffeine in cacao sets the two compounds side by side.

Anyone who is pregnant or breastfeeding, takes regular medication or has been given dietary advice by a clinician should put this question to a midwife, pharmacist or GP. A guide page cannot answer it and should not try.

What is in a Chaski tube

A 600 g tube of 77 per cent dark chocolate buttons, with four buttons as the daily dose stated on the pack. Single-origin cacao from Peru and Ecuador, from a farm our founder has visited, ground at low temperature. Coconut sugar as the sweetener and no added cane sugar. No emulsifiers, no seed oils, no palm oil. Every batch is tested for lead, cadmium and pesticides, which is the figure that matters given the table above.

It also carries Lion's Mane as a fruiting body extract and Cordyceps sinensis mycelium. The Ginkgo Biloba component is being replaced by 200 mg of Tremella fuciformis, a 10:1 fruiting body extract, per daily dose, and tubes are in that transition now.
