Foods and supplement choices that impact testosterone

While weight management, physical activity, and stress levels all affect testosterone levels, what you put on your plate can also play a role. From ashwagandha and omega-3s to selenium and zinc, here’s what science has to say about boosting your testosterone with nutrition.

If you’re experiencing decreased muscle mass, reduced concentration, or a decline in libido, you may want to take a look at your testosterone levels. This hormone is a key player in both men’s and women’s health. While it’s natural for testosterone to decrease with age, studies have found that levels have been declining in young adult men in recent decades [




. This decrease could be due to the growing obesity epidemic, reduced physical activity, and increased cortisol, and while these factors contribute to low testosterone, studies show that your food and supplement choices also play a role [




]. But before we take a deep dive into science-backed nutrition strategies, let’s discuss what testosterone is and how low levels can affect your body.

What is testosterone?

Testosterone is an androgen hormone produced by the adrenal cortex, the testes, and the ovaries [


]. Even though testosterone is present in both male and female bodies, it’s considered the primary sex hormone in men, and plays a role in mental health, bone and muscle mass, body hair, energy levels, certain behaviors (like aggression and competitiveness), fat storage, and sperm production [



Testosterone levels are much lower in women, but this hormone still plays a role in a female’s bone health, reproductive system, and sex drive [



What impacts testosterone levels?

Science shows that many factors play a role in testosterone levels, so here are some things that have an impact on this specific hormone.

  • Age. Research indicates that males’ testosterone levels decline, on average, 1.6% each year [


    ]. This is especially prevalent after 30 years old, as around 40% of men over the age of 45 and 50% of men in their 80s are considered hypogonadal (or having low testosterone levels) [



  • Genetics. Studies have found that testosterone has a high heritability and is greatly influenced by genetics [





  • Lifestyle. Physical activity levels and weight management play a role in testosterone levels; for instance, engaging in little exercise and being obese can decrease testosterone, whereas moderate physical activity and maintaining a healthy weight can improve levels [


    ]. But don’t overdo it–research shows that men who engage in intensive exercise training can develop low resting testosterone levels [


    ]. Stress also impacts testosterone, as emerging evidence suggests that hypogonadism is a response to psychological and physical stress [



  • Diet. Diets low in nutrient-dense foods and rich in processed foods have been associated with low testosterone levels [



  • Medication and steroids. Researchers have found that many antidepressants can impact testosterone and estrogen levels [


    ]. Additionally, it’s suggested that men and women who take anabolic steroids are at an increased risk for hypogonadism, even after they stop using steroids [



  • Health conditions. Studies show that chronic health conditions (such as AIDS, kidney disease, alcoholism, and liver cirrhosis) can negatively impact testosterone levels [





Average testosterone levels by age

You can determine your testosterone levels with a simple blood test. However, since these levels vary throughout the day, a second test may be needed to confirm results.

Here are some average testosterone levels by age and gender [



  • Men ages 13-17: 208 to 497 ng/dL

  • Men over 19 years old: 280 to 1,100 ng/dL 

  • Women ages 13-17: 17 to 32 ng/dL

  • Women over 19 years old: 15 - 70 ng/dL 

If your testosterone levels fall outside of this range, talk with your healthcare provider to see what options are right for you.

Symptoms of low testosterone

Low testosterone symptoms vary depending on your gender and age, but some symptoms associated with men include [





  • Low sex drive (libido)

  • Weight gain

  • Mood swings

  • Increased body fat

  • Reduced muscle mass

  • Low self-esteem

  • Hair loss

  • Difficulty getting and maintaining an erection

  • Trouble concentrating

  • Depression

Some symptoms of low testosterone in women may include [



  • Decreased libido

  • Reduced bone strength

  • Trouble concentrating

  • Depression

Are low testosterone levels dangerous for your health?

While it’s normal for testosterone levels to decrease with age, a lack (or very low levels) of this hormone can sometimes have long-term, serious effects on the body, especially for men. Research indicates that very low levels of testosterone in males has been linked to osteoporosis and an increased risk of death [



Foods that boost testosterone

If you’re looking for ways to increase testosterone, you may want to start by examining what you put on your plate. Here are some science-backed foods that can help boost testosterone levels.

Fatty fish.

Fatty fish (like salmon, herring, and trout) can increase testosterone levels due to their high vitamin D and omega-3 fatty acid content. In fact, studies have found that men who have low levels of vitamin D and omega-3s often have lower testosterone levels compared to those with higher levels of these nutrients [



Dark leafy greens.

Dark leafy greens (such as spinach, kale, and swiss chard) are well-known for their numerous health benefits, but notable research suggests that they may also promote testosterone levels. These vegetables are often high in


, a mineral that helps to increase testosterone by reducing oxidative stress and inflammation levels in the body. Studies have found that people with elevated magnesium levels had higher testosterone levels when compared to those with lower magnesium levels [







2 fried eggs in a non-stick pan with greens and toast in the background

Egg yolks. 

Egg yolks are rich in many vitamins and minerals, including selenium. This mineral may enhance testosterone production, as some research has found a correlation between high testosterone and elevated selenium levels [






Shellfish (such as shrimp, crayfish, crab, lobster, clams, scallops, oysters, and mussels) are excellent sources of zinc, selenium, and omega-3 fatty acids, all of which may help to support optimal testosterone levels [



Testosterone supplements

While the food you eat makes a difference in your testosterone levels, you may not get all of the nutrients you need from diet alone. Here are some of the best supplements to boost testosterone, according to science.

ashwagandha powder


This herb has numerous benefits for men, as scientific evidence suggests


may improve male fertility by naturally increasing testosterone levels and enhancing sperm quality in infertile men [


]. One randomized trial showed patients with a low sperm count who took 675 mg/day for 30 days improved sperm count by 167%, semen volume by 53%, and sperm motility by 57% from baseline, and that those in the placebo group experienced only minimal improvement [



Vitamin D. 

Vitamin D

plays a critical role in bone health, immunity, male reproductive health, and blood sugar (among other things), so if you’re deficient, you may be at a higher risk of bone fractures, COVID-19, and various other conditions. Additionally, studies have found that low vitamin D levels may be correlated with decreased testosterone levels in men [



Studies show that 42% of Americans are deficient in vitamin D, with that number increasing to 74% in older adults and 82% in people with dark skin [


]. 90% of Elo members start with low vitamin D

Since vitamin D is only obtained through sunlight exposure and a few foods,


may be necessary to meet your needs.


Fenugreek extract may have a positive impact on testosterone, as researchers found that 90% of men who took 500 mg/day experienced a 46% increase in testosterone after 12 weeks [



Saw palmetto extract. 

Studies indicate that saw palmetto extract may increase testosterone levels by blocking 5-alpha reductase, an enzyme which converts testosterone into dihydrotestosterone [


]. Men who took 1,200 mg/day for 14 days experienced a 38% increase in testosterone levels compared to a placebo [




This mineral plays a large role in testosterone levels, as a deficiency has been shown to negatively affect men’s sexual health and fertility [


]. However, research suggests that supplementation with 220 mg/zinc sulfate twice per day may prove beneficial for men with hypogonadism and infertility [




Studies show that men who took 0.5 - 1 g of ginger/kg of body weight/day experienced an 18% increase in testosterone compared to those who didn’t take a supplement [



Tongat Ali and Fadogia Agrestis. 

Tongat Ali


Fadogia Agrestis

have been touted as natural testosterone boosters, with some studies showing the former to have a positive effect on erectile function [



To test this, Elo co-founder and CEO Ari Tulla took both of these supplements to see if they had an impact on his testosterone levels; however, after 45 days, there was no measurable change. While Ari’s results were unsubstantial, other research shows positive results, so it’s best to consult with your healthcare provider before taking these (or any) supplements.

How to increase testosterone with lifestyle changes

Food and supplements aren’t the only way to increase testosterone levels; lifestyle factors also play a role. Here’s what science has to say about how your weight, physical activity, and stress levels affect testosterone.

  • Maintain a healthy weight. Research indicates that maintaining a healthy weight (or losing excess weight) can keep testosterone levels at an optimal level, as it’s been found that obese men have 30% lower testosterone levels compared to men at a healthy body weight [





  • Exercise. Strength training (in the form of full body weight exercises), specifically, has been shown to help improve testosterone levels in men, which in turn, contributes to muscle growth and improved athletic performance [



  • Increase your REM sleep. Getting enough sleep each night is important for your overall health, but studies also suggest that it can help with testosterone production. Since testosterone production takes place during REM sleep, it’s suggested to get at least

    one hour of REM sleep/night

    to maintain optimal testosterone levels [



  • Minimize stress. Research shows that elevated cortisol levels (caused by stress) can reduce testosterone levels [

Testosterone is an androgen hormone that plays a role in libido, sexual function, mental health, muscle mass, hair growth, and more. While it’s natural for testosterone to decrease with age, a lack (or very low levels) of this hormone can sometimes have long-term, serious effects on the body, especially for men. Studies suggest that including testosterone-friendly foods (such as fatty fish, egg yolks, and dark leafy greens) and supplements (like ashwagandha, Vitamin D, fenugreek, and zinc) in your diet may help to boost levels. You can also help increase testosterone by maintaining a healthy weight, engaging in strength training, prioritizing REM sleep, and minimizing stress.
