NMN has been measured in foods including edamame, avocado, broccoli, cucumber, cabbage, tomato, mushrooms, beef, and shrimp. But the amounts vary across samples and studies, and food-composition testing does not prove that eating one serving will measurably raise NAD+ in people.
That distinction matters. “This food contains NMN,” “your body can use NAD+ precursors,” and “this meal increases blood NAD+” are three different claims. Current evidence supports the first, explains the biological plausibility of the second, and leaves the third largely unanswered.
Which foods contain NMN?
The best-known list comes from a 2016 laboratory analysis, not from a human feeding trial. Researchers extracted NMN from food samples and measured it with high-performance liquid chromatography (HPLC).
| Food | NMN measured in 2016 | What the number means |
|---|---|---|
| Edamame | 0.47–1.88 mg/100 g | Range across tested samples |
| Avocado | 0.36–1.60 mg/100 g | Range across tested samples |
| Broccoli | 0.25–1.12 mg/100 g | Range across tested samples |
| Mushroom | 0.00–1.01 mg/100 g | Some samples were below the reported amount |
| Cabbage | 0.00–0.90 mg/100 g | Some samples were below the reported amount |
| Cucumber | Seed 0.56; peel 0.65 mg/100 g | Parts measured separately |
| Tomato | 0.26–0.30 mg/100 g | Range across tested samples |
| Raw beef | 0.06–0.42 mg/100 g | Range across tested samples |
| Shrimp | 0.22 mg/100 g | One reported value |
These numbers describe the samples and method in that paper. They are not universal values for every variety, growing condition, storage period, cooking method, or serving.
Use a three-layer evidence check
Before repeating a food claim, ask which evidence layer it has reached. This prevents a chemical measurement from turning into an untested health promise.
| Evidence layer | Question | Current answer |
|---|---|---|
| 1. Composition | Was NMN detected in the food sample? | Yes, across a small number of analytical studies. |
| 2. Bioavailability | How much survives digestion and becomes available? | Not established for a typical serving of each food. |
| 3. Human outcome | Does eating it raise NAD+ because of its NMN? | Not demonstrated by a controlled human feeding trial. |
Do not let evidence from layer 1 answer a layer-3 question. For broader context, read What Is NMN? Benefits, Safety, and What Human Studies Actually Show.
Why do NMN food lists disagree?
Newer analyses show that food measurements can differ substantially, which makes a fixed ranking unreliable. A 2025 open-access food-science study used a validated HPLC method and LC-MS/MS confirmation across plant foods purchased or collected in Brazil. It reported NMN concentrations from 40 to 13,000 micrograms per 100 grams of fresh weight and identified broccoli and green beans as relatively high among the samples tested.
That does not mean one paper “wins” and the other is wrong. The studies tested different samples, locations, plant materials, preparation conditions, and analytical workflows. The newer study also found that thermal treatment had varied effects across samples rather than supporting a single “cooking destroys NMN” rule.
- NMN and related NAD+ precursors occur naturally in foods.
- A measured value belongs to the tested sample and method.
- New and old values should not be silently combined into a universal ranking.
- More work is needed on processing, bioaccessibility, and dietary contribution.
A 2023 review reached a similar boundary: only a few studies had measured NMN and NR in foods, and their contribution to increasing NAD+ through diet remained underexplored.
Can you get “enough NMN” from food?
Science has not established a recommended dietary intake for NMN or a food-based target for raising NAD+. It is therefore not evidence-based to calculate how many avocados or bowls of edamame someone “needs” to match a supplement study.
Those comparisons may look precise, but they assume every serving contains the highest reported value, digestion and absorption are equivalent, the ingredient follows the same route, and a study amount is a personal recommendation. Those assumptions are not established by the food table.
Whole foods are still worthwhile for their established nutritional roles. They do not need to act like concentrated NMN products to belong in a varied diet.
Diet supports NAD+ pathways in more than one way
Nutrition’s connection to NAD+ is broader than trace NMN in selected foods. NIH explains that niacin—vitamin B3—is used to form the coenzymes NAD and NADP. Niacin is available from foods such as poultry, beef, pork, fish, nuts, legumes, grains, and fortified products. The body can also convert some tryptophan from protein foods into niacin equivalents, mainly in the liver.
That does not mean more niacin is always better or that high-dose niacin is an NMN substitute. It means a food-first discussion should include established nutrient pathways instead of treating one trace compound as the only route to NAD+ biology.
A practical checklist for evaluating “NAD-boosting foods”
Use this checklist whenever a food list promises more than the source measured.
- Identify the evidence type. Was it composition analysis, an animal experiment, a human feeding trial, or a supplement trial?
- Check the unit and food state. Milligrams and micrograms are not interchangeable; fresh, dry, raw, and cooked samples are not directly comparable.
- Look for a range. One precise number may hide variation.
- Separate precursor content from blood NAD+. Detection does not prove a measurable rise after eating.
- Do not borrow a supplement dose. A research protocol is not a food target or personal direction.
- Keep the whole food in view. Choose foods for broader nutrient value, preference, accessibility, and dietary fit.
If you are comparing foods with a finished product, review the current NMN Daily page and its latest label. A product page should be evaluated on its own formula, directions, warnings, and documentation; it should not inherit outcomes from a food analysis or a different product.
The bottom line
Several everyday foods contain measurable NMN, but “contains NMN” is not the same as “raises NAD+ in people.” Distinguish what a laboratory detected, what the body may metabolize, and what controlled human research actually measured.
Enjoy these foods as foods—not as a guaranteed NAD+ treatment. If you are considering a supplement, read the current label, compare the finished product with the evidence, and discuss it with a qualified healthcare professional when medicines, pregnancy, surgery, or a health condition are relevant.

Frequently asked questions
What food has the most NMN?
There is no stable universal winner. A 2016 analysis reported the highest range among its samples for edamame, while a 2025 plant-food analysis reported higher values for broccoli and green beans among its samples. Different foods, samples, and methods make a single definitive ranking unreliable.
Do avocados contain NMN?
Yes. A 2016 analysis measured 0.36–1.60 mg of NMN per 100 grams in the avocado samples tested. That is composition evidence, not proof that eating avocado raises blood NAD+.
Does broccoli contain NMN?
Yes. Both the 2016 and 2025 analytical studies detected NMN in broccoli, although their measured amounts differed substantially. Values should remain attached to the specific study and sample.
Can cooking destroy NMN in food?
The 2025 analysis found that thermal treatment had varied effects across samples. Current evidence does not justify a universal rule that cooking either preserves or destroys all NMN in every food.
Are NMN foods the same as NMN supplements?
No. Foods contain complex mixtures of nutrients and may contain small, variable amounts of NMN or related precursors. Supplements are concentrated finished products with their own labels, formulations, directions, and evidence boundaries.
