Vitamin D is an essential nutrient for everyone, but it's especially important for several key aspects of men's health: muscle, testosterone, virility and more. In this article, we're focusing on vitamin D benefits for men, deficiencies in men, and how vitamin d supplements and lifestyle changes can bring your status back up to par.
Let's get to it!
Key Takeaways
-
Vitamin D plays many roles in supporting peak masculine health, including helping testosterone, muscle, bone strength, sex drive, mood, heart health and more.
-
The recommended dietary allowance (RDA) of Vitamin D for men up to age 70 is 600 IU (15 mcg) per day -- but 92% of adult men consume less than 400 IU (10 mcg) per day
-
Vitamin D status may be improved with sensible sunlight exposure, Vitamin D-rich foods (mostly fish and animal products), and supplementation.
-
If you take a Vitamin D supplement, be sure to get the D3 form -- it is up to 87% more potent than the D2 form used in low-quality formulas.
Health Benefits of Vitamin D for Men
Vitamin D3 is also known as cholecalciferol or the “sunshine vitamin.” The body produces vitamin D when the skin is exposed to UVB rays from sunlight. In the diet, it is found in fatty fish like salmon and mackerel, fortified dairy products and plant milks, egg yolks, beef liver, and certain types of mushrooms.
Vitamin D benefits include enhancing bone strength, muscle strength, boosting immune function, regulating mood, supporting heart health, and helping to maintain overall wellness. Maintaining adequate testosterone levels is another crucial benefit of vitamin D for men. Let’s take a look at vitamin D3 benefits in the context of men’s health, specifically.
Bone Health
Vitamin D is great for maintaining healthy bones that literally support masculine wellness. Vitamin D strengthens bones by helping the body absorb calcium and phosphorus: two crucial minerals for bone growth. Plus, Vitamin D is involved in bone remodeling by osteoblasts and osteoclasts, the cells responsible for forming and resorbing bone tissue.(1) This may help to protect against bone fractures, which may be more of a concern as active men grow older.
Testosterone
Maintaining adequate Vitamin D levels can support optimal testosterone levels and testosterone production, which in turn helps to enhance men’s muscle development, bone density, and libido, as well as reducing fat mass and supporting weight management. Human clinical research has shown regular D intake raises blood levels of free testosterone, bioactive testosterone and total testosterone.(2) Learn more about testosterone supplements.
Muscle Function
Researchers believe Vitamin D may help muscle mass, strength and performance due to its role in stimulating growth of skeletal muscle fibers.(3,4) It has been suggested to help with age-related muscle weakness in more mature men, as well. Researchers have also noted that Vitamin D deficiency may lead to degeneration of muscle fibers that diminishes strength and weakens physical performance.(5)
Male Sexual Health
Optimal Vitamin D levels are associated with enhanced sexual and reproductive health in men. Researchers have found vitamin D receptors and metabolizing enzymes in the testis and spermatozoa, suggesting that it may regulate testis hormone production, sperm quality, semen quality, sperm function, and male fertility.(6)
In addition, A 2021 study published in the World Journal of Men’s Health suggests that erectile function, which is a key predictor of male sexual health, directly relies on adequate intake of vitamin D.(7)
Immune Function
Everybody could use a little immune support these days. But if you’re a man who works out at the gym, you should know that intense training can weaken the immune system.(8) Vitamin D deficiency has also been linked to a misfiring immune system and increased risk of infections.(9)
Increasing Vitamin D levels may help because it activates and regulates immune cells for a healthy and balanced immune response. Vitamin D even helps immune system barrier functions (skin and mucous membranes) that are a first-line defense against pathogens.
Mood
Vitamin D receptor sites are widespread in the brain, suggesting that the vitamin plays a vital role in brain function.(10) Vitamin D helps regulate the synthesis of neurotransmitters like serotonin, melatonin dopamine, which are crucial for mood regulation, feelings of well-being and restful sleep, and maintain blood pressure.(11)
Studies have found that vitamin D deficiency can contribute to negative emotions and depressive feelings; and that people with major depressive disorder and low vitamin D levels are most likely to see the greatest mood benefits from supplementation.(12,13)
Cardiovascular Health
Vitamin D3 benefits for men include broad-range support for cardiovascular health. This is crucial as heart problems are a leading health issue for men. Adequate levels of Vitamin D may help maintain blood pressure in a normal range and support smooth muscle function in the cardiovascular system.
Clinical trials suggest that low levels of Vitamin D are associated with an increased risk of heart attacks, congestive heart failure, and strokes, highlighting the importance of maintaining sufficient levels for cardiovascular health in men.(14)
How much Vitamin D do Men Need?
The Recommended Dietary Allowance (RDA) for Vitamin D varies depending on age, sex, and other factors.
-
According to general guidelines provided by the National Institute of Medicine, adult men up to age 70 should consume 600 IU (15 mcg) of vitamin D per day. After age 70, the RDA goes up to 800 IU (20 mcg).
These values are set to ensure adequate levels of Vitamin D to promote bone health and maintain calcium balance.
Some experts suggest more vitamin D than the amounts listed might be beneficial, especially for those at risk of deficiency due to limited sunlight, darker skin, obesity, or certain health conditions.
However, higher doses should be taken under medical supervision to avoid the risk of toxicity, since D3 is a fat-soluble vitamin D and can accumulate in the body.
Many men have low vitamin D levels.
The average daily intake of Vitamin D can vary widely based on dietary habits, geographical location, sun exposure, and the use of supplements. However, studies have shown that many men do not get enough Vitamin D through diet alone.
According to the United States National Institutes of Health, 92% of adult men consume less than 400 IU (10 mcg) of Vitamin D per day.(15)
These figures reflect dietary intake only and do not include vitamin D from sun exposure or supplementals. Still, the gap between dietary intake and the RDA highlights the challenge of getting enough Vitamin D.
If you're concerned about low vitamin D levels that are a risk factor for multiple health concerns, talk to your doctor. A simple blood test can tell you if your levels are low.
How Men Can Get Enough Vitamin D
Sun Exposure
It's called the sunshine vitamin with good reason: men can safely increase their Vitamin D levels through sensible sunlight exposure. This means spending about 10 to 30 minutes in the midday sun several times per week. Lighter skin tone requires less time in the sun; darker skin requires more.
Immediately after a short period of time in the sun, apply SPF 30+ sunscreen to protect the skin from harmful UV rays and minimize the risk of skin damage.
Consult with a doctor before full-body sunlight exposure, especially if you have skin health concerns. Or, you could just consider taking vitamin D in supplement form.
Did you know? Researchers have estimated that the body can produce 10,000 IU of Vitamin D from light exposure on a sunny day.(16)
Consume Vitamin D Foods
Want to correct low vitamin D levels via dietary sources and fortified foods? Here is a list of common foods naturally rich in Vitamin D, along with the approximate amount of Vitamin D each food supplies per serving:
-
Salmon (wild-caught): About 988 IU per 3.5 ounces (100 grams).
-
Mackerel: Around 643 IU per 3.5 ounces (100 grams).
-
Sardines (canned): Approximately 272 IU per 3.5 ounces (100 grams).
-
Cod Liver Oil: About 1,360 IU per tablespoon.
-
Tuna (canned): Roughly 268 IU per 3.5 ounces (100 grams).
-
Egg Yolks: Around 44 IU per yolk.
-
Fortified Milk: Generally 100 to 120 IU per 8 ounces (about 237 ml).
-
Fortified Yogurt: Approximately 80 to 100 IU per 6 ounces.
-
Fortified Cereals: Varies, but typically around 40 to 100 IU per serving.
-
Beef Liver: About 42 IU per 3.5 ounces (100 grams)
-
Mushrooms (UV-exposed): Vitamin D content varies; some types can provide as much as 400 to 1,000 IU per 3.5 ounces (100 grams). UV-exposed mushrooms include shiitake, button (white button, cremini, portobello), maitake, chanterelle, and morel.
These food sources can help individuals increase their Vitamin D intake, particularly in conjunction with adequate sunlight exposure. But supplementation may be advisable for some people – including vegetarians, vegans and those with severe deficiency – to get more vitamin D.
Vitamin D Supplements for Men to Consider
There are a lot of vitamin D supplements on the market, including vitamin D3 supplements. The most important feature to look for is a vitamin D3 (cholecalciferol) supplement rather than a vitamin D2 (ergocalciferol). Research suggests that vitamin D3 is more effective at increasing blood levels and up to 87% more potent than D2.(1 Also be wary of high dose supplements, as excessive intake can lead to toxicity.
Let’s look at some high-quality supplements that deliver the preferred D3 form in carefully calibrated doses.
