Back to the Cocoa Powder Guide
There is no official U.S. recommendation for how much cocoa powder per day is right. Most recipes use 1 to 2 tablespoons (about 5 to 11 g) per serving, and at that amount the practical limits are caffeine and theobromine for people sensitive to stimulants, and, for a daily habit, how much cadmium is in the specific cocoa you use.
Two tablespoons of unsweetened cocoa powder contain about 25 mg of caffeine, roughly a quarter to a third of an 8-ounce cup of coffee. If you are pregnant, breastfeeding, prone to kidney stones or taking medication, ask your health care provider what amount suits you.

What does a tablespoon of cocoa powder contain?
These are USDA typical values for unsweetened cocoa powder. Brands vary, so check the Nutrition Facts on your package.
| Nutrient | 1 tbsp (5.4 g) | 2 tbsp (10.8 g) |
|---|---|---|
| Calories | 12 kcal | 25 kcal |
| Fiber | 2.0 g | 4.0 g |
| Total sugars | 0.1 g | 0.2 g |
| Caffeine | 12 mg | 25 mg |
| Theobromine | 111 mg | 222 mg |
| Iron | 0.75 mg | 1.5 mg |
| Magnesium | 27 mg | 54 mg |
Our arithmetic from USDA FoodData Central values per 100 g. The full nutrient panel is in cocoa powder nutrition facts.
How much caffeine and theobromine is too much?
For most adults, the FDA cites 400 mg of caffeine a day as an amount not generally associated with negative effects. Two tablespoons of cocoa powder add about 25 mg, so for most people cocoa is a small part of the day’s caffeine. Cocoa’s main stimulant is theobromine, which acts more gently than caffeine but lasts longer; there is no U.S. reference limit for it.
| Drink | Caffeine |
|---|---|
| Hot cocoa with 2 tbsp cocoa powder | about 25 mg (USDA) |
| 8-ounce cup of coffee | about 80–100 mg (FDA) |
If cocoa in the evening affects your sleep, treat it like coffee and have it earlier in the day. Caffeine per serving and how it compares with other drinks are covered in how much caffeine is in cocoa powder.
How much cadmium does a daily cocoa habit add?
It depends entirely on the cocoa. Cocoa can carry cadmium from the soil, and a daily habit is where the level in your specific cocoa matters most. The arithmetic is simple once you have a lab number:
| Cadmium in the powder | In 1 tbsp (5.4 g) | In 2 tbsp (10.8 g) | 2 tbsp as a share of the 4.1 µg/day Prop 65 MADL |
|---|---|---|---|
| 0.081 mg/kg | about 0.44 µg | about 0.87 µg | about 21% |
| 0.30 mg/kg | about 1.6 µg | about 3.2 µg | about 79% |
| 0.60 mg/kg (EU maximum) | about 3.2 µg | about 6.5 µg | about 158% |
California’s Proposition 65 maximum allowable dose level is a reference for total daily intake, not a safety line for one food. A cocoa at the EU maximum would pass that reference on its own at two tablespoons a day. Where cadmium and lead come from, and which limits apply, is in heavy metals in cocoa powder.
What are the side effects of cocoa powder?
At recipe amounts most people notice none. These are the effects worth knowing about, and what drives each one:
| Possible effect | What causes it | What to do |
|---|---|---|
| Jitters, fast heartbeat, trouble sleeping, headache | Caffeine and theobromine, mostly in sensitive people or at large amounts | Use less, and not late in the day |
| Upset stomach or bloating | Large servings of fiber-rich cocoa, or stimulants in sensitive people | Start with 1 tbsp and increase slowly |
| Concern for people prone to kidney stones | Oxalates: a 2011 analysis measured about 650–783 mg of total oxalate per 100 g of commercial cocoa powder (dry matter), roughly 35–42 mg per tablespoon | Ask your clinician about your total oxalate intake |
| Extra sugar and calories | Sweetened hot chocolate mixes and desserts, not the cocoa itself | Use unsweetened cocoa and sweeten to taste |
| Long-term heavy-metal intake | Cadmium and lead levels, which vary by brand and origin | Choose a cocoa with a published, dated lab report |
Who should not make cocoa a daily habit without asking a clinician first?
- Pregnant or breastfeeding, or trying to become pregnant: the FDA recommends talking to your health care provider about whether to limit caffeine.
- Prone to calcium-oxalate kidney stones: cocoa is a high-oxalate food.
- Sensitive to caffeine, or taking medication that interacts with stimulants.
- Buying for children: ask a pediatrician about caffeine and portions.

Does the amount change with how you use cocoa?
| If you are… | Typical amount | Worth knowing |
|---|---|---|
| Having a daily hot cocoa or smoothie | 1–2 tbsp per serving | The level in your specific cocoa matters most here |
| Baking | As the recipe says | A whole pan of brownies may use ½ cup (about 43 g), shared across many servings |
| New to cocoa or sensitive to caffeine | Start at 1 tbsp | Theobromine’s effect lasts longer than caffeine’s |
| Following a low-carb plan | 1–2 tbsp | About 1 g net carb per tablespoon (USDA typical values) |
Why does the source matter more for a daily habit?
An occasional cake uses cocoa once in a while; a daily cup uses it hundreds of times a year. That is when a published number helps. The cocoa Grevista distributes is single-origin Vietnamese Trinitario, unsweetened and non-alkalized. In an April 2022 report by TSL Science (ISO/IEC 17025) on the producer’s sample, cadmium measured 0.081 mg/kg, about 14% of the EU maximum, and arsenic, lead and mercury were not detected (below 0.003 mg/kg). The report describes the sample tested, not every batch; read it in full on our Lab Results & Awards page.
Frequently asked questions
Can I have cocoa powder every day?
Many people do. There is no official daily limit; the things to watch are your caffeine tolerance, any medical advice about oxalates or caffeine, and the heavy-metal level of the cocoa you use.
Is 2 tablespoons of cocoa powder a day too much?
For most adults it adds about 25 mg of caffeine, 222 mg of theobromine and 25 calories. At a cadmium level of 0.081 mg/kg it adds about 0.87 µg of cadmium; at higher levels, proportionally more.
Does cocoa powder keep you awake?
It can in sensitive people. Cocoa contains caffeine and theobromine, so an evening cup affects some people’s sleep.
Can cocoa powder upset your stomach?
Large servings can cause bloating or discomfort in some people. Start with a tablespoon and see how you feel.
What are the side effects of eating too much cocoa powder?
Mostly stimulant effects such as jitters, a faster heartbeat, headache or poor sleep, plus digestive discomfort. For people prone to kidney stones, oxalate intake is also a concern.
What should you read or do next?
- Heavy metals in cocoa powder — read this next, because for a daily habit the cadmium level of your specific cocoa matters more than the number of spoons.
- Cocoa powder nutrition facts — read this if you are counting calories, fiber or net carbs per serving.
- How much caffeine is in cocoa powder — read this if an evening cup is keeping you awake.
- How to tell if cocoa powder is pure — read this before your next purchase, since a daily habit is worth checking the label for.
- Lab Results & Awards — open this to see what a published, dated report looks like when you ask a brand for one.
If cocoa is a daily habit, a published cadmium number is worth having: the Grevista 200 g (7 oz) unsweetened, non-alkalized cocoa powder.
