Some foods, drinks and supplements often associated with generally healthy eating may influence hormone levels in limited or extreme circumstances, according to medical experts.
Testosterone levels are shaped by many factors, including diet, exercise, sleep, stress and metabolic health. Certain foods and supplements, however, can impact hormone pathways, Dr. Kyle Gillett, a Kansas physician specializing in family and obesity medicine, said on a recent episode of Dr. Andrew Huberman’s “Huberman Lab Essentials.”
Gillett said some dietary patterns have a well-documented effect on testosterone levels, particularly when taken to extremes.

“If you’re young and healthy, and you don’t have metabolic syndrome, then caloric restriction will likely decrease your testosterone,” he said.
High amounts of alcohol also lower testosterone, he added.
While individual foods may play a role in certain edge cases, lifestyle factors such as sleep, body composition, stress and physical activity overwhelmingly drive testosterone health for most men, experts say.
“Sleep deprivation, obesity, insulin resistance, acute illness and chronic stress suppress testosterone far more than any single food ever could,” Dr. Khameinei Ali, a practicing physician in New York and immediate past president of the Westchester County Medical Society, told Fox News Digital.

But for those experiencing low energy, reduced sex drive or other hormone-related symptoms, concentrated foods or supplements may worsen the issue, making it worth reassessing diet and lifestyle.
People don’t need a diagnosed condition to consider hormone testing, Gillett said — noting that a persistent symptom can be enough to ask a doctor about checking levels.
Experts also highlighted several common foods, drinks and supplements that may be worth watching.
1. Turmeric and curcumin supplements
In theory, men with already low levels of DHT or reduced androgen sensitivity could be more susceptible to effects from highly concentrated turmeric or curcumin supplements, though evidence in humans is limited, said Gillett.

The concerns largely stem from lab research, said Anneliese Cadena, a North Carolina nurse practitioner and clinical advisor for the men’s wellness company Feel30.
“Some animal and cell studies have shown a decrease in testosterone at high doses, but those types of studies don’t necessarily translate to the same effects in people,” she told Fox News Digital.
“In practice, I worry far more about megadose supplements than about someone adding turmeric to their cooking.”
Dr. Justin Houman, a urologist at Cedars-Sinai Medical Center in Los Angeles, shared similar concerns about high-potency supplements.
“In practice, I worry far more about megadose supplements than about someone adding turmeric to their cooking,” he said.
2. Dairy
Certain milk proteins may influence levels of prolactin, a hormone that can interfere with testosterone production in susceptible individuals, Gillett said.
“Prolactin is going to also inhibit the release of testosterone from the pituitary,” he said.
Experts say prolactin usually affects testosterone only when levels are unusually high due to medical issues, not from normal eating habits, and that everyday diet or lifestyle factors aren’t known to lower testosterone through prolactin in healthy men.
3. Polyphenol-rich plant foods
“Let’s say you have a diet high in plant polyphenols,” Gillett said, referring to the compounds found in foods such as green tea and berries.
“Many of those inhibit the enzyme that converts testosterone to DHT.”

Cadena pointed out that those compounds are generally beneficial when consumed in normal amounts.
“Plant compounds such as polyphenols consistently support metabolic, cardiovascular and even reproductive health when they’re part of a balanced diet,” she said.
4. Alcohol
Alcohol intake remains one of the clearest diet-related risks for testosterone health, according to experts.
“High alcohol will decrease testosterone,” Gillett said.
Experts agreed that alcohol’s effects are often compounded by its impact on sleep quality, body fat and metabolic health — all of which are closely tied to hormone levels.

Regular or heavy drinking has been consistently linked to lower testosterone, Cadena noted, particularly when paired with poor sleep or weight gain.
“We used to think that one or two drinks a day were safe, but we now know there’s really no safe dose of alcohol,” she said.
5. Ultra-processed foods
Ali said men concerned about testosterone should focus less on individual foods and more on overall diet quality.
“The bigger concerns are excess alcohol, ultra-processed foods, chronic under-eating and supplements marketed as ‘testosterone boosters’ without credible evidence or transparent ingredient lists,” he said.
Overall, experts stressed that testosterone health is not fragile and that moderation, consistency and metabolic health matter most.

“Most men do not have a food problem,” Houman agreed. “They have a sleep, stress, weight or activity problem.”
