Melatonin shows up in a surprisingly wide range of foods, from tart cherries and nuts to eggs, meat, and even wine. Your body produces melatonin naturally in response to darkness, but you also take in small amounts through what you eat and drink. The quantities in food are tiny compared to supplement doses, but they’re measurable and, in some cases, enough to nudge your blood levels upward.
Fruits and Vegetables With Melatonin
Tart cherries, specifically the Montmorency variety, are the most well-known dietary source. A serving made from 100 grams of tart cherries contains roughly 0.135 micrograms of melatonin. That’s a fraction of what you’d get from a supplement (typically 1 to 5 milligrams), but studies on tart cherry juice still show modest sleep improvements, likely because the fruit also contains other compounds that support melatonin’s effects.
Other fruits with detectable melatonin include grapes, strawberries, tomatoes, and peppers. Among vegetables, mushrooms stand out. Pistachios contain some of the highest concentrations measured in any food, reaching levels that, gram for gram, rival low-dose supplements. Corn, rice, and oats also contain small amounts, though rice and oats measure only around 1 to 5 nanograms per gram of dry weight.
Meat, Eggs, and Dairy
Melatonin isn’t limited to plants. Researchers have confirmed its presence in lamb, beef, pork, chicken, fish, and eggs, all in the nanogram-per-gram range, comparable to what’s found in most plant foods. Colostrum, the first milk produced after birth, also contains measurable amounts.
Regular cow’s milk has melatonin too, and milk collected at night contains more than milk collected during the day, since cows follow the same light-driven melatonin cycle humans do. This led to the development of “night milk” products marketed in some countries as a sleep aid, though the amounts remain small.
Wine, Beer, and Fermented Foods
Fermentation creates melatonin. Wine and beer both contain it, though concentrations vary widely depending on grape variety, yeast strain, and how many fermentation steps the product goes through.
In wines, melatonin levels typically range from about 0.05 to 8 nanograms per milliliter, with Merlot at the higher end (around 8.1 ng/mL) and some Malbec wines at the lower end (0.16 ng/mL). Certain pressed and racked wines have been measured at 74 to 423 ng/mL, dramatically higher than most table wines. Beer contains less overall: standard 5% beers measure around 169 to 333 picograms per milliliter (roughly a thousand times less than wine), while non-alcoholic beers have even lower levels.
Bread is another fermented food with melatonin. During dough fermentation, melatonin-related compounds increase from about 4 ng/g to nearly 17 ng/g. Baking degrades some of that, but measurable amounts survive in the finished loaf.
How Cooking Affects Melatonin Levels
Heat breaks down melatonin. In bread, researchers found that baking caused significant degradation of melatonin compounds that had built up during fermentation. The crust, which reaches the highest temperatures, retained less than the inner crumb. This pattern likely applies to other cooked foods as well: the longer and hotter the cooking, the more melatonin is lost. Raw or lightly processed foods will preserve more of their original melatonin content.
Food Sources vs. Supplements
The gap between food and supplements is enormous. A typical melatonin pill contains 1 to 5 milligrams. A serving of tart cherry juice delivers about 0.135 micrograms, which is roughly 7,000 to 37,000 times less than a standard supplement dose. Even the richest food sources provide only a tiny fraction of what a pill delivers.
That said, melatonin from food enters your body alongside other nutrients that may enhance its effects or improve absorption. Tryptophan, the amino acid your body uses to make melatonin naturally, is abundant in turkey, eggs, milk, and nuts. Eating tryptophan-rich foods gives your body raw material to produce more melatonin on its own, which is a different pathway than consuming preformed melatonin directly.
What’s Actually in Melatonin Supplements
Nearly all melatonin supplements sold worldwide are chemically synthesized rather than extracted from food. The manufacturing processes are well established and cost-effective, though some production methods generate potentially harmful byproducts. A small number of “natural” supplements use phytomelatonin sourced from green algae (Chlorella) grown in bioreactors, sometimes combined with herbs like valerian, passionflower, lemon balm, or hops. These plant ingredients contain extremely low melatonin levels on their own, often just 2 to 16 nanograms per gram.
Label accuracy is a real concern with supplements. A study analyzing 31 melatonin products found that more than 71% didn’t contain an amount within 10% of what the label claimed. The actual content ranged from 83% less to 478% more than stated. Even different batches of the same product varied by as much as 465%. If you’re taking a supplement labeled as 3 milligrams, you could be getting anywhere from about 0.5 milligrams to over 14 milligrams without knowing it.
Putting It All Together
Melatonin is present across the food supply in trace amounts. Tart cherries, pistachios, grapes, eggs, fish, milk, and fermented products like wine and bread all contain it. None of these foods deliver doses comparable to even the lowest supplement, but a diet rich in these foods contributes small, steady amounts alongside the tryptophan your body needs to make its own. For anyone looking to boost melatonin through diet alone, focusing on tart cherry products, pistachios, and nighttime milk will get you the most per serving, while keeping in mind that raw or minimally processed versions retain more than heavily cooked ones.
