Most men know they should be taking care of themselves but knowing which supplements can best support their goals is another thing. Here’s a straightforward look at the supplements that actually matter and what each offers.

Key Takeaways

Today we’ll explore:

  • Which supplements are most relevant for men’s health
  • What each one supports in the body
  • How to prioritize based on individual wellness goals
  • What to look for in a quality supplement.

Key Terms

  • Probiotics: beneficial species of bacteria or yeasts that are found in the human digestive tract and which support nutrition, digestion, and immune health.
  • Creatine: a compound made from three amino acids that helps your body produce rapid energy for high-intensity muscle and brain activity.
  • Saw palmetto: a small palm tree whose dark berries are used to make dietary supplements for prostate and urinary health, and supporting hair density.
  • Testosterone: a major sex hormone that controls puberty, muscle growth, and sex drive. Highest levels are found in males where it is produced in the testicles.
  • Bioavailable: refers to the rate at which a nutrient can enter the bloodstream and be metabolized and utilized by cells throughout the body.

Men have specific nutritional needs for a large variety of wellness aspects, some of which may shift over time with age and lifestyle changes. Eating a diet rich in whole foods is the ideal way to get these important nutrients, but modern diets often lack sufficient nutrition. When that happens, targeted supplements can help plug any gaps and can support better energy, heart health, prostate health, muscle function, and overall wellness.

 

Nutrient Facts You Should Know

Common Nutrient Gaps for Men

Many men do not get adequate amounts of key nutrients through diet alone,1 including vitamin D, magnesium, and omega-3 fatty acids. This may be due to soil depletion, food processing methods, or lifestyle factors. Furthermore, increased physical activity or stress can drive your body’s need for certain nutrients.2 Selecting fortified foods and targeted supplements can go a long way to ensuring you have the nutrients you need each day for optimal wellness.1

How Nutritional Needs Shift with Age

As part of the aging process, multiple aspects of wellness can begin to change, with enhanced support becoming increasingly important. For example, men may begin to experience a decline in testosterone levels as early as their 30s or 40s. While this is a common aspect of aging, it can impact mood and cognitive function, metabolism, cardiovascular health, and even bone mineral density—elements of overall health that can benefit from targeted supplementation.3

A daily multivitamin can provide a broad nutritional foundation for healthy aging, while targeted supplements can more directly address specific goals that may not have been as top of mind in youth.

 

Core Supplements for Men’s Health

Daily Multivitamin

Studies show that a high-quality daily multivitamin can help fill common nutritional dietary gaps in many vitamins and minerals, and that this supplementation can contribute to aspects of healthy aging.4

Although a multivitamin supplement can serve to enhance or buttress nutrition, it should not be seen as a replacement for a healthy diet. There are many multis formulated with ingredients specifically chosen to meet men’s particular needs.

Vitamin D3

Vitamin D deficiency is a widespread concern, with around one billion people worldwide estimated to be low in this critical nutrient. Those who do not receive adequate exposure to sunlight regularly or who do not get enough from diet are at particular risk.5

This is concerning, as vitamin D regulates the functions of more than 200 genes in the body and is directly linked to promoting bone health, immune function, cardiovascular health, and healthy testosterone levels.5,6,7 In cases where diet and sun exposure aren’t enough, supplementation is recommended, generally with highly-absorbable vitamin D3.5

Magnesium

Magnesium is involved in more than 300 biochemical processes including energy production, muscle function, nerve function, and healthy sleep. However, many men, especially later in life, do not get adequate magnesium through diet alone.8 To promote healthy serum levels, magnesium supplements, including well-tolerated magnesium glycinate, are available in a variety of forms. Learn more in Magnesium Benefits & Uses.

Omega-3 Fatty Acids

Omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been strongly associated with support for healthy blood pressure and blood lipid levels. They have also been liked to joint comfort.9 Studies also indicate that omega-3 essential fatty acids may benefit brain and cognitive health.10

Omega-3 supplements may feature EPA and DHA derived from either fish or krill. Learn more about the difference between these sources in Krill Oil vs. Fish Oil: Which Has More Benefits?. For those who prefer a vegan option, Swanson offers a Plant-Based Omega-3 supplement featuring sustainable microalgal oil.11

Vitamin B12

Vitamin B12 is generally gained from consuming animal products. This can mean that those following a vegetarian or vegan diet aren’t getting enough B12, so supplementation can be a helpful alternative. B12 supports the synthesis of DNA (which in turn leads to the formation of red blood cells) and is closely linked to energy metabolism. Research has also indicated that vitamin B12 may be associated with benefits to cognitive function and mood, as it promotes the health of nerve cells..12,13

Vitamin C

Vitamin C is a powerful antioxidant that supports immune function and healthy aging and is also required for the natural production of collagen for healthy skin and connective tissues. Vitamin C has also been linked to proactive cardiovascular and vision health, and its ability to regenerate antioxidants already present in the body can contribute to overall cellular protection over time.14

Physical activity and stress can promote the natural production of free radicals in the body, possibly leading to oxidative stress. As a result, antioxidant levels may decrease during these times, and so the need for additional sources, whether from diet or supplements, is greater for men experiencing high activity, occasional stress, or immune activation. Vitamin C can bolster these levels and deliver added protection.15


Supplements for Men’s Heart Health

Fish Oil and Omega-3s for Cardiovascular Support

Omega-3 essential fatty acids must be gained through diet (ex. fatty fish like salmon), but getting enough can be a challenge, so supplements can be generally more efficient.16 These include both EPA and DHA which have been linked to supporting healthy blood pressure and blood lipid levels already within the normal range.17 This is because these fatty acids play a vital part in supporting healthy cellular membranes—necessary for cell signaling and communication. When cellular membranes are supported, they help keep the heart and blood vessels strong, flexible, and are better able to maintain proper blood pressure.

CoQ10 for Heart and Energy Support

Coenzyme Q10 (CoQ10) is essential for proper cellular energy production (facilitating the formation of adenosine triphosphate—ATP). This is a critical to heart health, as the heart requires large amounts of ATP for contraction and pumping mechanisms. ATP is an essential energy source for normal function of cardiac muscle during each beat.18

Over time, the body begins to produce less CoQ10 on its own.19 Additionally, those who take prescription statins may also experience lower levels of CoQ10, sometimes leading to muscle discomfort or weakness.20 For those who are older or may be concerned about muscle health and overall healthy aging, CoQ10 supplements can deliver standardized amounts of this nutrient to bolster serum levels.20 In the case of supplements, the active form known as ubiquinol has been shown to be more readily absorbed and used by the body after age 40.21

Magnesium for Blood Pressure and Heart Rhythm

Magnesium has been shown in research to support metabolic regulation, a healthy heart rhythm, and blood pressure levels already within a normal range—central aspects of healthy aging.22


Supplements for Men’s Prostate Health

Saw Palmetto

An excellent source of nutritional support for the prostate, saw palmetto is one of the most widely studied supplements benefiting men’s health. Research has examined its role in supporting healthy prostate function, particularly as men age.23 Due to its ability to help urinary tract flow for healthy adults, saw palmetto is a very commonly recommended herbal supplement for men.

Zinc for Prostate and Testosterone Support

Another important supplement for prostate and testosterone support is the micromineral zinc. Zinc has been associated with critical support for prostate health in older men.24 It’s highly concentrated in prostate tissue where it promotes cellular function and signaling. Additionally, zinc is required by the body for the production of testosterone and also works along the hypothalamic-pituitary-gonadal axis, which regulates hormone production.25,26

Anyone with concerns about their prostate health should consult with a doctor before beginning or changing their supplement routine.


Supplements for Energy and Stress Support

B Vitamins for Energy and Stress

B vitamins help your body convert food into usable energy, making them especially relevant if you’re looking for daily energy support. Vitamins B1, B6, and B12 also support nervous system health and help the body produce neurotransmitters involved in mood and stress response.27,28 For men with busy schedules, high stress, or nutrient gaps, a B-complex supplement can be a practical way to support energy metabolism and everyday resilience.28

Magnesium for Sleep and Recovery

Known for promoting restful sleep (which can help ease stress and lead to better days),29magnesium is also linked to daytime energy metabolism and muscle comfort,30 especially after exercise or physical exertion.

Magnesium supports a healthy recovery after exertion by promoting muscle relaxation and comfort. It also helps aging men maintain lean muscle mass by supporting protein synthesis and healthy testosterone levels.31

Ashwagandha for Everyday Stress Support

For centuries, ashwagandha has been valued for its health benefits, and modern science is discovering new ways it can support wellness, including as a potent adaptogen. Adaptogens like ashwagandha work to help the body deal with stress in a healthy way, regulate stress hormones like cortisol, promote a sense of calm, and support deeper, more restful sleep.32


Supplements for Muscle and Physical Performance

Creatine

Creatine supplements have been shown to promote the formation of lean muscle mass as part of targeted exercise. It can also encourage physical performance by supporting the production of adenosine triphosphate (ATP)—the primary source of cellular energy.33 When the body’s cells have adequate energy, you can also experience more “get up and go” during your day.

Creatine has additional benefits outside of the gym. For a deeper dive, read Creatine Benefits Beyond Muscle.

Protein Powder for Muscle Support and Recovery

Adequate protein intake is essential for muscle maintenance, recovery, and healthy body composition. As a complete protein (possessing all nine amino acids) derived from dairy products, whey is recognized for its fast absorption and ease of use by the body in the production and repair of muscle tissues.34

For those who don’t tolerate dairy or follow a vegan diet, there are many plant-based protein options. These are often sourced from peas, soy, hemp and other seeds, or brown rice.35

Vitamin D3 and Magnesium for Bone and Joint Health

Vitamin D has been shown in research to greatly enhance the absorption of the primary bone mineral calcium, thereby better ensuring it gets to the bone tissues where it’s needed most. In addition to its other benefits, magnesium works to activate vitamin D for enhanced calcium and phosphate regulation—critical to maintaining strong, healthy bones and joints.36


Gut Health and Immune Support

Probiotics for Gut and Immune Health

A healthy gut promotes digestion, enhanced immune function, and overall wellness, including mood support via the gut-brain axis. One of the best ways to support gut health is by promoting a balanced microbiome with probiotics—beneficial bacteria that naturally occur in the human digestive tract.37 Ensuring you have a healthy balance of probiotics, along with sufficient prebiotic fiber to help sustain these beneficial microbes, can mean enjoying benefits such as better nutrition and improved immune function.38 A good probiotic supplement is one that offers multiple strains for overall support, or specific strains for particular needs or goals. Learn more in What Are Probiotics? And Why Do I Need Probiotics?

Vitamin C and Zinc for Immune Function

Vitamin C and zinc support immune health through complementary mechanisms. Vitamin C helps maintain healthy immune cell function, provides antioxidant protection, and supports the body’s natural physical barriers through its role in collagen production.

Zinc is essential for the normal development and function of immune cells and helps support healthy immune signaling and antioxidant defenses. Together, they promote a healthy immune response and overall immune system function.39


Supplements for Sexual and Reproductive Health

Male sexual and reproductive health can be supported in a number of ways. CoQ10 can support healthy blood vessels,40 while beetroot is a source of inorganic nitrates that support blood flow and vascular health.41 A traditional herbal supplement that has been studied for potentially supporting sexual performance in humans is horny goat weed. In some animal studies, this supplement showed positive effects on circulatory enhancement of sexual organs.42

Other supplements can support aspects of reproductive health, such as zinc for healthy sperm production,43 and saw palmetto for prostate health.23 Another herbal ally to consider is ashwagandha. Among its many benefits, ashwagandha is known to also support the healthy production of testosterone.44


How to Build Your Supplement Routine

Start with the Essentials

For most men a practical starting point is a high-quality daily multivitamin, vitamin D3, magnesium, and omega-3 fatty acids. From there, add targeted supplements based on specific goals: prostate health, cardiovascular support, or energy and physical performance. Consistency matters more than complexity. A simple routine taken every day outperforms an elaborate one taken inconsistently. Check out Swanson’s in-house experts and their top supplement stacks.


What to Look for in Quality Supplements

Seek out a respected company with a legacy of transparency, such as a GMP Verified manufacturer who utilizes third-party testing and high-standard ingredient sourcing. It’s also a good practice to check bottle labels for forms of nutrients that offer better bioavailability, such as vitamin D3 (over D2) or magnesium glycinate.

Swanson’s selection of men’s health supplements are designed with these expectations and adherence to quality in mind.

When to Check with a Healthcare Provider

It’s always recommended that you check with your doctor before beginning or changing a supplement routine. Be sure to discuss any health concerns you may have or any prescription medications you may take. Lab tests can offer insight into any deficiencies you may have that can benefit by supplementation.
