If we were to closely analyse the male and female body, we would discover notable differences. Men stand apart from women not only in terms of muscle mass, but in various other aspects as well. Testosterone, in particular, plays a vital role in men, which is also closely connected to prostate health and fertility. It is precisely these factors that determine the specific nutrients that men should prioritize in their diet.
Why do the nutritional needs of the male body differ from those of the female body?
There are no significant differences in the nutritional needs between boys and girls. However, as they gradually grow and enter puberty, which is accompanied by hormonal changes, some distinctions begin to emerge. This period is characterized in boys by rapid growth and the development of muscle mass. This, in turn, is associated with higher protein requirements and overall increased energy intake needs. As a result, the nutritional requirements of the male body start to differ from those of the female body.
- Spermatogenesis, or the production of sperm, benefits from the intake of nutrients such as selenium and omega-3 fatty acids. [18,40]
- For example, zinc is important for the production and function of the male sex hormone testosterone. 
- The prostate, an organ exclusive to the male body, requires nutrients with antioxidant properties such as selenium, vitamin C, and other for its health.
- If you want to learn more about the differences between men and women and how this affects their nutritional needs, be sure to check out the following article: Women & Nutrition: The Most Important Vitamins and Minerals for Health and Beauty
- Detailed information about women’s nutritional needs can also be found in this article: Do Men and Women Share the Same Nutritional Needs?
Why should men prioritize proper nutrition and a healthy lifestyle?
Why should you eat healthy? A healthy diet and lifestyle require a certain degree of discipline, and sometimes it may be easier to stick to familiar habits and old routines. However, it is definitely worth overcoming this discomfort because nutrition is a factor that directly affects your health.
Healthy diet is associated with a lower occurrence of many health issues.
Studies have shown that, for example, it helps reduce the risk of developing various types of cancer, such as prostate and colorectal cancer. These were among the most common types of cancer in men according to data from 2020, along with lung cancer. [39,48]
Healthy diet also contributes to a lower incidence of:
- cardiovascular problems such as heart attack and stroke.
- obesity, which is a significant risk factor for the development of many diseases. [23,29,33]
Men will also surely appreciate the effect of nutrition on testosterone levels. Research has shown that testosterone is on a gradual decline in the male population. However, testosterone is crucial for the male reproductive system, muscle growth, overall physical performance, and many other areas of male health. [23,29,33]

What should men focus on in their diet?
1. Energy Requirements
It may not come as a surprise that men typically need to consume more calories compared to women. This is primarily because men tend to have a higher basal metabolic rate (BMR), which is the energy required by the body for basic physiological functions during rest and sleep. The BMR increases with a higher proportion of muscle mass. Considering that men are generally larger and have more muscle mass and lower body fat percentages, they naturally have a higher energy requirement. Additionally, the male sex hormone testosterone plays a role in promoting muscle growth, further contributing to their higher caloric needs. [3,17]
The total energy requirements also depend on the type, amount, and intensity of physical activity. If a man has a physically demanding job or engages in regular sports or exercise, it will have an impact on his body’s calorie needs.
What is the recommended daily intake of calories for men?
According to EFSA (European Food Safety Authority), men should consume an average of 2340-3340 kcal per day. The lower values apply to men with sedentary lifestyles, and the requirement increases with increasing physical activity. This means that active athletes may ultimately have an even higher calorie need than the recommended range. 
The individual daily energy requirement can be calculated based on several parameters. If you’re interested in knowing how many calories your body needs in relation to your goals, our online energy intake calculator can assist you in this.
Protein intake is directly related to the amount of muscle mass. Since men naturally have a higher proportion of muscle mass, they typically require a higher protein intake. Proteins are crucial for maintaining and repairing muscles. Additionally, if a man is actively trying to build muscle, his protein requirements further increase.
Testosterone also has a significant impact on protein requirements. It increases muscle protein synthesis (MPS), which is the process of building new proteins in the body. During puberty, when the effects of testosterone become more pronounced, protein needs in men are substantially increased. 
Similar to calorie intake, protein requirements also depend on the level of physical activity. A man who engages in manual labour and further incorporates activities like running or working out at the gym has significantly higher protein needs compared to someone who sits all day in an office.
What is the recommended daily intake of protein for men?
An individual with a sedentary lifestyle should ideally consume around 0.8 grams of protein per kilogram of body weight (BW) per day. However, according to some recommendations, a slightly higher intake of 1 gram per kilogram of body weight may be advantageous.
Protein requirements increase with sports and physical activity. According to the International Society of Sports Nutrition (ISSN), individuals primarily engaged in strength training should aim for a daily protein intake ranging from 1.4 to 2 grams per kilogram of body weight to ensure sufficient protein intake. [19,45]

3. Omega-3 Fatty Acids
Omega-3 fatty acids (FAs) rank among polyunsaturated fatty acids and are one of the essential building blocks of healthy fats. They are known for their numerous positive effects on health, including their impact on the cardiovascular system, brain, and immune function. 
The essential alpha-linolenic acid (ALA) helps maintain optimal blood cholesterol levels, while eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are important for eye and brain health. 
These fatty acids have generally shown a positive impact on cardiovascular health. Therefore, men should not overlook their importance, as they have a higher risk of developing cardiovascular diseases compared to women.
Omega-3 fatty acids, including EPA and DHA, are also present in sperm membranes. They are believed to play a role in sperm flexibility, motility, and overall quality. A meta-analysis has shown that omega-3 supplementation in infertile men can improve sperm motility. Moreover, a deficiency of DHA in sperm has been linked to low sperm concentration. Thus, it seems that omega-3 fatty acids may have a positive impact on male fertility. [13,18]
What is the recommended daily intake of omega-3 for men?
- 250 mg EPA + DHA
- the intake of ALA should ideally represent around 0.5% of the total energy intake (TEI) 
- the intake of ALA should ideally represent around 0.5% of TEI
- there is no specific recommendation for the intake of EPA and DHA 
Where to find omega-3 fatty acids?
- The essential alpha-linolenic acid (ALA), which needs to be obtained through diet, can be found in foods such as walnuts, rapeseed oil, flaxseeds, flaxseed oil, chia seeds, and soy. [21,44]
- EPA and DHA are primarily found in fatty sea fish and fish oil. Their plant-based source is seaweed or marine algae. [21,44]

4. Vitamin D
Vitamin D boasts a wide range of effects and is needed for proper muscle and immune system function. Additionally, it plays a role in the proper absorption of calcium and phosphorus, making it crucial for healthy bones and teeth. 
One of the organs where this vitamin is synthesized are the testes. They are therefore believed to be important for sperm production and function. Additionally, this organ supposedly plays a role in testosterone production. However, further research and clarification are needed to fully understand these potential effects on male reproductive health. 
What is the recommended daily intake of vitamin D for men?
- EFSA recommendation: 15 μg 
- DACH recommendation: 20 μg 
Where to find vitamin D?
The majority of vitamin D is obtained from exposure to sunlight. The highest food sources of vitamin D include fatty sea fish, organ meats, fish oil, and egg yolks. There are also some mushrooms and lichens that produce vitamin D when exposed to UVB radiation. 
Foods rich in vitamin D
|egg yolk||5.4 μg|

Selenium is an important antioxidant that helps the body combat oxidative stress. It also plays a crucial role in the immune system and thyroid function. Additionally, selenium is involved in maintaining the health of hair and nails. 
This mineral is essential for the proper formation of sperm and overall fertility. This is likely due to its antioxidant properties, which help protect sperm from the damaging effects of free radicals generated by oxidative stress. However, it appears that supplementation may only be beneficial for individuals with low selenium levels in their bodies. When selenium levels are already optimal and dietary supplements increase them to excessive levels, it may potentially have undesirable effects. [1,28,35]
What is the recommended daily intake of selenium for men?
- EFSA recommendation: 70 μg 
- DACH recommendation: 70 μg 
Where to find selenium?
The best sources of selenium include Brazil nuts, fish, seafood, and organ meats. Considerable amounts of selenium can also be found in whole grains, meat, and dairy products. The selenium content in foods can vary significantly because its presence in plant-based foods depends on the amount of selenium in the soil where the plants were grown. For animal-based foods, the selenium content depends on the selenium levels in the animal feed. [43,47]
Foods rich in selenium
|Selenium content (100 g)|
|Brazil nuts||1920 μg|
|chicken liver||55 μg|
|plain yoghurt||10 μg|
Zinc is an important mineral that the body needs for optimal functioning of the immune system, eyesight, and maintenance of healthy bones. It also plays a role in carbohydrate, protein, fatty acid and vitamin A metabolism. 
Furthermore, zinc contributes to maintaining normal blood testosterone levels. It also plays a vital role in the conversion process of testosterone into its biologically active form. Additionally, zinc helps prevent the conversion of testosterone into estrogen, which can result in conditions such as gynaecomastia, the enlargement of breast glands in men, when excessive amounts of the female sex hormone are present.
Zinc is also involved in proper sperm function. It is believed to contribute to the strength of sperm membranes and protect sperm from oxidative stress. Insufficient zinc intake may therefore be a potential risk factor for low sperm quality and reduced fertility. [11,12,40]
Last but not least, zinc is also important for prostate health. The prostate naturally contains a high concentration of zinc, and its levels serve as an indicator of proper prostate function. [12,40]
What is the recommended daily intake of zinc for men?
- EFSA recommendation: 14 mg 
- DACH recommendation: 11-16 mg 
Where to find zinc?
The best food sources of zinc from among animal-based sources include red meat, fish, and eggs. Among plant-based foods, legumes and whole grains are among the leading sources of zinc. 
Read more about zinc in the following article: Zinc: What Is It Good For, What Causes a Deficiency and What Are the Best Sources?
Foods rich in zinc
||Zinc content (100 g)|
|Edam cheese||3.8 mg|
Magnesium is a mineral that the body requires for maintaining optimal electrolyte balance and protein synthesis. It is essential for the function of muscles, bones, and teeth. Additionally, magnesium plays a crucial role in the proper functioning of the nervous system and mental well-being. 
This nutrient likely has a positive impact on testosterone production. Studies have shown that if a man has low levels of both magnesium and testosterone, magnesium supplementation may lead to an increase in the levels of this male sex hormone. 
Magnesium is also associated with a lower occurrence of muscle cramps. These are common, particularly among athletes, and magnesium supplementation in the form of a dietary supplement can contribute to alleviating this issue. 
What is the recommended daily intake of magnesium for men?
- EFSA recommendation: 350 mg / day 
- DACH recommendation: 350 mg 
For more information on magnesium intake, deficiency symptoms, and health benefits, you can refer to the following article: Cramps, Fatigue, Irritability or Sleep. What Else Does Magnesium Affect?
Foods rich in magnesium
|Magnesium content (100 g)|
|pumpkin seeds||550 mg|
|sunflower seeds||325 mg|
|dark chocolate 70-85 %||228 mg|
8. Vitamins with antioxidant effects
Antioxidants are substances that help protect the body against free radicals, which are formed as a result of oxidative stress. They are thus associated with reducing the risk of various conditions, such as cardiovascular diseases and cancer. In men, antioxidants also play an important role in protecting sperm and the prostate. Antioxidants include various vitamins, as well as the aforementioned selenium and zinc. [16,18]
Which vitamins rank among antioxidants?
- EFSA recommendation: 3 mg / day 
- DACH recommendation: 2-5 mg 
- riboflavin (vitamin B2)
- EFSA recommendation: 1.3 mg / day 
- DACH recommendation: 1.4 mg / day 
Fibre is an indigestible component found in plant-based foods. Although the body cannot break it down, and it passes through the digestive tract mostly unchanged, it holds numerous health benefits. It is necessary for proper digestion and bowel movements, as well as for an optimal composition of the gut microbiota. Fibre also affects things beyond the digestive tract, such as blood sugar levels and immune function.
Not only is fibre necessary for proper digestion, but it also influences the health of the digestive tract itself. Sufficient fibre intake is associated with a lower risk of colorectal cancer. One meta-analysis indicated that for every 10g increase in daily fibre intake, there is an approximate 10% reduction in the risk of developing this disease. 
Where to find fibre?
Fibre is found exclusively in plant-based foods. Good sources of fibre include legumes, whole grains, vegetables, fruits, and nuts and seeds.
However, you can also include fibre in your diet in the form of various dietary supplements, such as:
- apple fibre
- a complex supplement like Daily Fiber with a combination of multiple types of fibre.
What is the recommended daily intake of fibre for men?
The recommendations of various nutrition institutions may vary slightly, but they all suggest a daily intake in the range of 25–35 grams. According to EFSA, the recommended daily intake for a healthy adult is 25 grams of fibre. [8,25,37]
You can achieve such an intake through sources like:
- 70 g of whole grain pasta (approx. 6 g of fibre),
- 50 g of oats (approx. 7 g of fibre),
- 50 g of whole grain toast bread (approx. 3 g of fibre),
- 100 g of carrots (approx. 3 g of fibre),
- 100 g of banana (approx. 2.5 g of fibre),
- and 30 g of almonds (approx. 4 g of fibre). [8,25,37]
What dietary supplements can be beneficial for men’s health?
1. Tribulus Terrestris
Tribulus Terrestris is an extract from the Tribulus terrestris plant. Traditional medicine utilized it to deal with fertility issues and low libido. Today, it is primarily recognized as a natural alternative to steroids. Studies have shown a correlation between this plant and increased testosterone levels, muscle growth, and performance. [14,36]
Ashwagandha, also known as Indian ginseng, is renowned for its numerous health effects. It ranks among adaptogens, which are substances that help the body better cope with stress. It is also used in cases of infertility and sexual dysfunction. Research suggests that Ashwagandha may have an impact on sperm production and quality, as well as testosterone production. [4,26]
Fenugreek is a plant used in traditional medicine to improve libido. This usage has persisted to this day because it contains steroid saponins, which may potentially increase testosterone levels. In addition, it has promising effects in other areas of health. It may help lower blood sugar levels (glycaemia), making it useful for individuals who need to maintain optimal glycaemic control. [24,27]
4. Saw Palmetto
Serenoa repens (Saw Palmetto) is a palm plant whose fruits are used to produce an extract. It is rich in fatty acids such as myristic acid, oleic acid, and others. Studies have shown that it has an effect on prostate health. 
DAA (Aspartic Acid) is naturally found in the human body and involved in the function of endocrine glands and the nervous system. However, studies have shown that it may also play a role in increasing testosterone levels and male fertility. There is also a potential impact on growth hormone production and muscle growth. 
Apart from the aforementioned vitamins and minerals, there are other bioactive substances that can have antioxidant effects and contribute to reducing the risk of cancer and protecting sperm from oxidative stress. 
Substances that have shown promising results in research include, for example:
Ginseng is used in traditional Chinese medicine due to its potential effects on immunity, cognitive abilities, and mood. As an adaptogen, it may be useful in managing stress. It has also been shown to potentially impact sexual health and support the production and function of sperm. [15,22]
8. Complex dietary supplements
Many dietary supplements combine multiple nutrients and active ingredients targeting specific areas of men’s health. You can find supplements focusing on prostate health, testosterone support, antioxidant intake, or a combination of various nutrients in the form of a multivitamin that is generally formulated for men’s health.
What are the main takeaways?
The male body has its unique functions and characteristics that come with specific nutritional requirements. These include a naturally higher proportion of muscle mass, testosterone production and function, sperm quality, and prostate health. Due to these specifics, men should pay attention not only to their calorie and protein intake, but also to specific vitamins and minerals such as zinc, selenium, and vitamin D. In conclusion, a healthy and diverse diet emphasizing these specific nutrients can significantly contribute to better overall male health.
