Men's vitamin needs are often less discussed than women's, yet the evidence for targeted nutritional support across men's health — from skin and hair to cardiovascular function, fertility, and prostate health — is both substantial and practical. While fundamental micronutrient requirements are broadly similar across sexes, there are areas where men's biology, lifestyle factors, and age-related changes create specific nutritional priorities worth addressing deliberately. This guide covers the vitamins and nutrients most relevant to men at different life stages, with an emphasis on what the research actually supports.
Foundation Vitamins: Non-Negotiables for Every Man
Before addressing gender-specific topics, it is worth establishing the nutrients most commonly insufficient in men's diets across Europe — not because men's needs are dramatically different, but because gaps in these areas have the most measurable consequences.
Vitamin D insufficiency is at least as prevalent in men as in women. Adequate vitamin D supports testosterone production, muscle function, immune defence, and cardiovascular health — all areas of direct relevance to male wellbeing. European men who work indoors and do not supplement are at high risk of vitamin D insufficiency from October through March. Supplementation of 1,000–2,000 IU/day is appropriate for most adult men in northern and central Europe.
Magnesium is frequently underconsumed and is particularly relevant to men who exercise regularly, experience significant occupational stress, or have high alcohol intake — all factors that increase magnesium turnover. Magnesium supports muscle recovery, sleep quality, testosterone regulation, and cardiovascular health.
Zinc warrants specific mention for men. Zinc is concentrated in the testes and prostate, plays a direct role in testosterone metabolism, and is required for sperm production and function. Men with high physical output, restrictive diets, or high alcohol intake are most at risk of zinc insufficiency. Zinc is found naturally in red meat, shellfish (oysters are the richest source), legumes, and pumpkin seeds.

Skin Health: Vitamins A, C, and E
Men's skin is structurally thicker than women's due to higher androgen levels, but this does not make it immune to oxidative damage, UV exposure, or the effects of daily shaving — which causes repeated micro-abrasion and can compromise the skin barrier over time.
Vitamin A is the most critical vitamin for skin cell turnover and renewal. It regulates the rate at which skin cells divide and differentiate, and adequate vitamin A status prevents excessive keratinisation, maintains moisture retention, and supports wound healing after daily shaving irritation. Dietary sources include liver, dairy, eggs, and orange and yellow vegetables (via beta-carotene). It is worth noting that very high supplemental doses of preformed vitamin A (retinol) are associated with toxicity — keeping intake within recommended limits is important.
Vitamins C and E work synergistically as antioxidants in skin tissue, protecting against UV-induced cell damage and supporting collagen maintenance in the dermis. Vitamin C is also required for collagen synthesis — the structural protein responsible for skin firmness and elasticity. Men who smoke have substantially elevated requirements for vitamin C due to the oxidative burden of cigarette smoke; the typical recommendation is an additional 35 mg/day above the standard reference value. These vitamins are readily available from plant oils, nuts, citrus fruits, and green vegetables. Our hair, skin and nails supplements collection includes relevant products for men focused on skin and hair health.
Hair Health and Male Pattern Baldness: What Nutrition Can (and Cannot) Do
Androgenetic alopecia — male pattern baldness — is primarily driven by genetic sensitivity of hair follicles to dihydrotestosterone (DHT), a testosterone metabolite. Nutrition cannot reverse this process, but nutritional deficiencies can accelerate hair thinning independently of hormonal factors and are worth identifying and correcting.
Vitamin A is particularly relevant here: both deficiency and significant excess have been associated with hair loss. At adequate levels, vitamin A supports the sebaceous glands that maintain the hair shaft, and the normal cell cycling of hair follicles. Getting vitamin A primarily through food (including beta-carotene from vegetables, which the body converts to vitamin A only as needed) rather than high-dose supplements is the safest approach.
The B-vitamin complex — particularly biotin (B7), niacin (B3), pantothenic acid (B5), and riboflavin (B2) — collectively supports the energy metabolism of rapidly dividing hair follicle cells, contributes to scalp circulation and keratin production, and helps maintain hair structural integrity. While biotin is often heavily marketed for hair growth, its effect is most pronounced in individuals who are genuinely deficient — which is less common than marketing suggests.
Iron is a significant contributor to diffuse hair shedding (telogen effluvium) when deficient, even in men — this can be caused by chronic disease, very restrictive diets, or gastrointestinal blood loss. If unexplained hair thinning occurs alongside fatigue, ferritin levels are worth checking.
[tip:For men concerned about hair health and general vitality, the most impactful dietary steps are often the simplest: ensuring adequate protein intake (hair is made of keratin, a protein), maintaining consistent intake of B vitamins from whole grains and animal products, and addressing any iron or zinc deficiency identified by blood testing. Supplement stacks marketed specifically for hair growth are rarely more effective than correcting underlying nutritional gaps.]Fertility and Reproductive Health
Male fertility is influenced by several micronutrients that directly affect sperm production, morphology, motility, and DNA integrity. This is a clinically relevant area — male factor infertility contributes to approximately half of all infertility cases in couples, and nutritional status plays a meaningful modifiable role.
Vitamin C is present in very high concentrations in seminal plasma, where it protects sperm DNA from oxidative damage. Research has found associations between low vitamin C status and higher rates of sperm DNA fragmentation. Vitamin C's role in supporting sperm motility and count has been examined in several controlled studies, with generally positive findings at doses in the 200–1,000 mg/day range.
Vitamin E similarly protects sperm membranes from lipid peroxidation — the fatty acids that make up sperm cell membranes are highly vulnerable to free radical damage, and vitamin E provides membrane-level antioxidant protection. Combined vitamin C and E supplementation has been specifically studied for male fertility improvement.
Zinc is directly involved in spermatogenesis (sperm production), testosterone synthesis, and sperm motility. Men with low zinc status consistently show reduced sperm counts and testosterone levels in research. Zinc supplementation in deficient men has demonstrated improvements in sperm parameters in controlled trials.
Folate and vitamin B12 — often considered primarily in the context of maternal health — are also important for male fertility. Both are required for DNA synthesis in rapidly dividing cells, including sperm precursors, and adequate status in both partners is associated with better reproductive outcomes.
Cardiovascular Health
Men develop cardiovascular disease on average 7–10 years earlier than women, which makes cardiovascular health a legitimate priority throughout adult life. Several vitamins and nutrients have well-established roles in cardiovascular risk management:
The B vitamins (B6, B12, and folate) manage homocysteine levels through their roles in methylation metabolism. Elevated homocysteine is an independent cardiovascular risk factor, and its regulation depends on adequate supply of all three of these vitamins working together.
Vitamin K2 (MK-7) has attracted significant research interest for its role in directing calcium into bone (where it belongs) rather than arterial walls — a process relevant to both cardiovascular calcification risk and bone health. Vitamin K2 is found primarily in fermented foods and some animal products.
Omega-3 fatty acids (EPA and DHA) are not vitamins but are among the most evidence-backed cardiovascular nutrients for men, contributing to normal heart function and triglyceride regulation. Men who eat oily fish fewer than twice per week are good candidates for omega-3 supplementation. Browse our cardiovascular supplements for relevant nutrient options in this area.
Prostate Health: A Later-Life Priority
Prostate health becomes a relevant concern for most men from their forties onwards, with benign prostatic hyperplasia (BPH) affecting the majority of older men to some degree. Key nutrients with research relevance include zinc (concentrated in prostate tissue), lycopene (a carotenoid from tomatoes associated with lower prostate cancer risk in observational research), selenium, and saw palmetto extract. Dedicated prostate support formulations typically combine these with beta-sitosterol and stinging nettle root.
