Foods That Boost Testosterone: What the Evidence Actually Shows (and Foods That Lower It)

Short answer: No single food raises testosterone the way a medication does, but a few foods help by fixing shortfalls the body needs for normal hormone production. The best supported picks are zinc-rich foods (oysters, beef, crab, pumpkin seeds), vitamin D sources (salmon, trout, eggs, fortified milk), extra virgin olive oil and an overall diet that does not cut fat too low. The foods that most reliably work against testosterone are heavy alcohol and a diet that drives weight gain. If you have symptoms of low testosterone, get a blood test before changing your plate.

Key Takeaways

• Food helps most when it corrects a deficiency. Men with low zinc or low vitamin D are the ones most likely to see a difference.^[3][5][6]
• Three ounces of farmed oysters provide about 32 mg of zinc, nearly three times the 11 mg daily RDA for men.^[2]
• A meta-analysis of 6 intervention studies found that low-fat diets lowered total and free testosterone in men.^[7]
• Extra virgin olive oil raised testosterone by 17.4 percent in a small 3-week trial of healthy Moroccan men.^[8]
• Soy does not lower testosterone in men according to a 2021 meta-analysis of clinical studies, but heavy drinking and excess body fat do.^[1][9]
• Fatigue, low drive or erection changes deserve a doctor visit and a morning blood test first, not a grocery list.^[1]

How Food Affects Testosterone

Testosterone is made mostly in the testes, from cholesterol, under signals from the brain (luteinizing hormone, or LH). Food cannot override that system, but it supplies the raw materials and cofactors the system depends on. That is why the research on “foods that increase testosterone” keeps finding the same pattern: the clearest benefits show up in men who were short on something to begin with, such as zinc, vitamin D or total calories from fat.

Diet also works indirectly through body weight. Harvard Health notes that excess body fat, especially around the abdomen, can lower testosterone, and that losing weight through diet and exercise may raise testosterone production by up to 30 percent according to some research.^[1] For many men, the overall eating pattern matters more than any single “superfood.”

Age plays a role too. Harvard Health puts the typical decline at about 1 percent per year after adulthood, with obesity, chronic illness, certain medications, stress and sleep apnea as other common causes of low levels.^[1] Food can help with some of these causes, not all of them.

Foods That Boost Testosterone: The Evidence-Based List

1. Oysters and other shellfish (zinc)

Oysters are the richest common source of zinc. The NIH Office of Dietary Supplements lists 32 mg of zinc in 3 ounces of raw farmed Eastern oysters and 28.2 mg in 3 ounces of cooked Pacific oysters, against an RDA of 11 mg per day for adult men.^[2] Cooked blue crab provides about 3.2 mg per 3 ounces.

Why it matters: a 2023 systematic review of 38 studies (8 clinical, 30 animal) concluded that zinc deficiency is linked to lower testosterone, that serum zinc correlates positively with total testosterone, and that the size of any benefit from extra zinc depends on a man’s starting zinc and testosterone levels.^[3] In plain terms, zinc fixes a shortage; it does not push normal levels higher. Keep total zinc from food and supplements under the adult upper limit of 40 mg per day.^[2] More detail is in our guide to whether zinc increases testosterone.

2. Beef and other red meat (zinc, protein)

Three ounces of roasted bottom sirloin supply about 3.8 mg of zinc, roughly a third of the daily value.^[2] Animal foods also provide zinc that is absorbed better than zinc from beans, nuts and whole grains, because plant phytates bind zinc in the gut.^[2] Lean cuts a few times per week fit comfortably in a balanced diet.

3. Pumpkin seeds, beans and whole grains (plant zinc)

Roasted pumpkin seeds provide about 2.2 mg of zinc per ounce.^[2] Vegetarians and vegans may have lower zinc status because of phytates, and the NIH suggests soaking beans, grains and seeds before cooking to improve absorption.^[2] If you eat little or no meat, these foods are your main zinc supply, so eat them daily.

4. Fatty fish: salmon, trout, sardines (vitamin D, omega-3)

Fatty fish are among the few natural food sources of vitamin D. Three ounces of cooked sockeye salmon contain about 570 IU and farmed rainbow trout about 645 IU, compared with an RDA of 600 IU for men aged 19 to 70.^[4] Harvard Health lists fatty fish among the foods linked to higher testosterone.^[1]

The vitamin D evidence is a good example of “fix the deficit, not more.” In a 1-year randomized trial, overweight men in a weight-loss program who took 3,332 IU of vitamin D daily saw total testosterone rise from 10.7 to 13.4 nmol/L, while the placebo group did not change.^[5] But in a 12-week randomized trial of 98 healthy men with normal testosterone at baseline, 20,000 IU of vitamin D per week had no significant effect on total testosterone.^[6] See our page on vitamin D for men for testing and dosing.

5. Whole eggs (yolk nutrients)

One large egg provides about 44 IU of vitamin D, all of it in the yolk.^[4] Eggs also deliver protein and dietary fat in an easy package, which matters given the low-fat diet findings below. They are a useful building block, not a hormone fix on their own.

6. Extra virgin olive oil (monounsaturated fat)

In a controlled trial of 60 healthy Moroccan men aged 23 to 40, a 2-week run-in on butter was followed by 3 weeks of either virgin argan oil or extra virgin olive oil. Testosterone rose 17.4 percent in the olive oil group and 19.9 percent in the argan oil group, with LH rising as well.^[8] The study was small and short, so treat it as encouraging, not proof. Using extra virgin olive oil as your main cooking and salad fat is a low-risk swap that also fits a heart-healthy diet.

7. Enough total dietary fat

The strongest diet-level finding is about what happens when fat is cut too far. A 2021 meta-analysis of 6 intervention studies (206 men) found that low-fat diets lowered total, free and urinary testosterone compared with higher-fat diets, with a larger effect in European and North American men.^[7] The authors called for more randomized trials. The takeaway is not to load up on fried food, but to avoid very low-fat eating if hormones are a concern, and to get fat from fish, eggs, olive oil, nuts and seeds.

8. Onions and other vegetables

Harvard Health includes onions in its short list of foods linked to higher testosterone.^[1] Direct human trial data for onions specifically are thin, so think of onions, leafy greens and other vegetables as part of the nutrient-dense, weight-friendly pattern that supports normal hormone production, rather than as targeted boosters.

9. Pomegranate (weak evidence)

Pomegranate is often promoted online. The main human data come from a 2012 conference abstract: 60 healthy volunteers (22 men, 38 women) drank pomegranate juice daily for 2 weeks, and salivary testosterone rose by an average of 24 percent.^[10] There was no separate control group, saliva is not the standard clinical test, and the results were not a full peer-reviewed trial. Enjoy pomegranate as a fruit, but do not count on it.

Testosterone Boosting Foods at a Glance

Foods That Kill Testosterone (and Some That Do Not)

Alcohol, especially heavy drinking

Heavy drinking can lower testosterone, impair sexual function and reduce sperm count. Harvard Health advises reducing or avoiding alcohol, or limiting it to one drink or fewer per day.^[1] Of all the foods and drinks that lower testosterone, this is the one most worth acting on.

Trans fats and heavily processed fried foods

In a cross-sectional study of 209 healthy young men in Spain, higher trans fat intake was associated with lower total and calculated free testosterone.^[11] This is an association, not proof of cause, but trans fats have no health upside, so limiting fried fast food and packaged baked goods is an easy call.

A diet that drives weight gain

Excess abdominal fat is linked to lower testosterone, and weight loss may raise it.^[1] Calorie-dense ultra-processed snacks and sugary drinks matter here mainly because they make weight gain easy. Our article on how to increase testosterone naturally covers the exercise and sleep side of the same equation.

Soy: mostly a myth

Soy is the food men worry about most, but a 2021 expanded meta-analysis of clinical studies concluded that neither soy nor isoflavone intake affects male reproductive hormones.^[9] Tofu, edamame and soy milk can stay on the menu.

Canned foods and plastics with BPA

Harvard Health suggests avoiding BPA-containing plastics and canned foods and looking for “BPA-free” labels.^[1] This is a packaging issue rather than a food issue, and a simple one to manage.

A Simple Day of Eating

• Breakfast: two whole eggs with vegetables cooked in extra virgin olive oil, plus a glass of fortified milk.
• Lunch: salmon or trout over greens and beans, dressed with olive oil.
• Snack: a small handful of pumpkin seeds or a piece of fruit.
• Dinner: lean beef or shellfish two or three nights a week, with onions, vegetables and a whole grain.
• Drinks: water most of the time, one alcoholic drink or fewer.

Add 7 to 9 hours of sleep and regular resistance training, which Harvard Health identifies as the other major lifestyle levers for testosterone.^[1]

When to See a Doctor Instead

Low sex drive, erection changes, infertility, loss of muscle, more body fat or persistent fatigue can have many causes, including low testosterone, thyroid problems, sleep apnea, medications and depression. Harvard Health recommends asking your doctor about testing if you have these symptoms, and notes that blood should be drawn in the morning, before 10 a.m., because levels fluctuate. A total testosterone of 300 ng/dL or higher is generally considered normal.^[1] Read our overview of the signs of low testosterone before your appointment. Doctors often start with intensive lifestyle changes, and food is part of that, but it is not a substitute for a diagnosis.

Where Supplements Fit

Food is the foundation. If you also use a supplement, choose one with a transparent label. Ultra Bann is a natural male vitality supplement by DL Bioproducts with seven botanicals and every amount listed on the label (no proprietary blend): Thai Butea superba, Panax ginseng, Cynomorium songaricum, black ginger, tongkat ali, epimedium and reishi, taken as one capsule every 2 days. It does not replace the diet above or a medical evaluation. You can see the full label and details on the Ultra Bann shop page.

Frequently Asked Questions

What food increases testosterone the most?

No food reliably raises testosterone in a man whose levels and nutrient status are already normal. For men low in zinc, oysters are the most concentrated source, with about 32 mg per 3 ounces.^[2] For men low in vitamin D, fatty fish such as salmon and trout are the best natural food sources.^[4]

How fast can diet change testosterone levels?

Trials have run from weeks to a year. The olive oil study measured changes after 3 weeks,^[8] while the vitamin D trial that showed an increase in deficient men ran for 12 months.^[5] Changes driven by weight loss take as long as the weight loss itself.

Do eggs raise testosterone?

There is no strong direct evidence that eggs raise testosterone. They supply vitamin D in the yolk, protein and dietary fat, and very low-fat diets are linked to lower testosterone,^[4][7] so whole eggs are a reasonable part of a testosterone-friendly diet.

What foods kill testosterone?

The best supported culprits are heavy alcohol use and eating patterns that lead to excess body fat.^[1] Trans fats are associated with lower testosterone in observational data.^[11] Soy, despite its reputation, did not affect male reproductive hormones in a 2021 meta-analysis.^[9]

Should I take zinc or vitamin D pills instead of eating these foods?

Only if a test or your doctor shows you need them. Benefits appear mainly in men who are deficient,^[3][5][6] and both nutrients have upper limits: 40 mg per day for zinc and 4,000 IU per day for vitamin D in adults.^[2][4]
