The supplement industry is crowded with bold promises, but only a handful of products deliver measurable results. If you’re a man looking to optimise your energy, support healthy ageing, and fill genuine nutritional gaps, this guide cuts through the noise. We’ll focus on what the science actually supports, which supplements and men’s supplements matter most for men’s health, and how to build a practical routine that works with your lifestyle.
Quick answer: the 5 best core supplements for men in 2026
Most men benefit from a focused stack of supplements that address common deficiencies and support cellular health. Rather than buying a dozen different bottles, prioritise these five evidence-backed options:
Quality multivitamin – covers baseline vitamins and minerals to fill nutritional gaps from an imperfect diet. The best vitamins, such as those found in a quality multivitamin, are important for addressing common nutrient deficiencies in men.
Vitamin D3 – supports immune function, bone health, mood and testosterone levels, especially crucial for UK men with limited sun exposure. Vitamin D deficiency is common among men in winter months, particularly in areas with low sun exposure, and vitamin D is recommended for everyone, including men, especially during autumn and winter. A quarter of men are deficient in vitamin D, yet only one in ten takes a vitamin D supplement as recommended.
Omega-3 fatty acids – promotes cardiovascular health, brain function and joint support
Magnesium – aids muscle function, sleep quality, blood pressure regulation and stress resilience
Nicotinamide Riboside (NR) – supports cellular energy, mitochondrial health and healthy ageing by boosting NAD+ levels
NADBio specialises in premium NR available in liposomal capsule form for enhanced absorption and pure powder form for flexible dosing. The NR + Resveratrol stack combines these NAD+ boosting benefits with polyphenol support for a comprehensive longevity approach, all third-party tested and UK compliant.
Worth noting: supplements work best when they complement a nutrient-dense healthy diet, quality sleep and regular exercise. They’re not a replacement for the fundamentals. A balanced and varied diet should negate the need for a dietary supplement, but some individuals may still require them.

How supplements fit into men’s health and longevity
Modern UK lifestyles create a perfect storm for nutrient depletion. Long hours at desks, limited sunlight for much of the year, high stress levels and convenience-focused eating patterns mean that even health-conscious men often fall short on key nutrients. For men aged 30 to 65, strategic supplementation can bridge these gaps and support the body’s natural processes. When selecting men’s supplements, it’s important to choose products that specifically support men’s health, muscle building, and fitness goals, while considering ingredient quality and individual needs.
The key word here is “supplement.” These products work alongside good habits, not instead of them. A Mediterranean-style diet rich in whole grains, vegetables, lean proteins and healthy fats provides the foundation. Regular resistance and cardio training keeps muscles, heart and metabolism functioning well. Seven to nine hours of quality sleep allows recovery and hormone regulation. Stress management prevents cortisol from undermining your efforts. Most men may benefit from incorporating additional protein, fiber, and vitamin D into their routine to help bridge nutritional gaps.
What makes the difference for men in this age bracket is cellular health. Your body relies on a molecule called NAD+ for hundreds of metabolic reactions, including energy production, DNA repair and mitochondrial function. Unfortunately, NAD+ levels decline significantly from around age 30 onwards, with some research suggesting a 50% reduction by middle age. This decline affects energy levels, muscle performance, cognitive function and the ageing process itself.
NADBio is a UK-based longevity-focused brand using high-purity, third-party tested ingredients while complying with UK and EU regulations, including FSA rules. It’s worth noting that NMN currently has an open novel food application with the FSA UK and therefore cannot be legally sold by any supplier in the UK. That’s why NADBio focuses on legal, well-studied NR as the primary NAD+ precursor for British customers.
Best daily multivitamin for men
A well-formulated men’s multivitamin acts as nutritional insurance. It’s not a replacement for real food, but it does provide a safety net for days when your diet falls short. Think of it as covering the basics so you can focus on more targeted supplements for specific goals. Choosing the best vitamins as part of your daily health routine is important—targeted vitamins like vitamin D and folic acid can address common nutrient deficiencies that many men experience.
When choosing a comprehensive multivitamin for men, look for these key nutrients:
Nutrient | Why Men Need It |
|---|---|
B vitamins (B6, B12, folate) | Energy production, nervous system function, red blood cells formation |
Vitamin D3 | Bone health, immune system, testosterone support |
Vitamin K2 | Calcium absorption, cardiovascular health |
Magnesium | Muscle function, sleep, blood pressure |
Zinc | Immune function, testosterone levels, normal spermatogenesis |
Selenium | Thyroid function, antioxidant support |
One important consideration: men generally need less supplemental iron than women. The RDA for adult men is just 8 milligrams, and excessive iron can lead to oxidative stress. Unless you have a diagnosed deficiency confirmed by a blood test, avoid multivitamins with high iron content.
Choose products that provide roughly 50 to 100 percent of the Nutrient Reference Value (NRV) for most vitamins and minerals. Megadoses aren’t necessary and can sometimes cause problems. If you’re already taking NR or other targeted supplements, check labels carefully to avoid doubling up on specific nutrients. Many studies have found that multivitamins do not significantly impact health outcomes like memory loss or heart disease, but they can still help fill nutritional gaps.
A good best multivitamin pairs well with NR and resveratrol as a daily base stack for energy, immunity and healthy ageing.
Vitamin D3 and bone health: essential for UK men
Vitamin D plays a vital role in immune function, maintaining testosterone within the normal range, mood regulation, muscle function and bone health. For UK men, getting adequate levels from sun exposure alone is nearly impossible for much of the year.
Between October and April, the sun sits too low in the sky for the skin to produce meaningful amounts of vitamin D. The UK government recommends 10 micrograms (400 IU) per day as a baseline, though many experts advise higher doses under medical supervision, particularly for men who work indoors, have darker skin, or are over 50.
When selecting a vitamin d supplement, opt for D3 (cholecalciferol) rather than D2 (ergocalciferol). D3 is primarily found in animal products and is typically more effective at raising blood levels. Vegan options made from lichen are now widely available for those following plant based foods diets.
Men over 30 should get their vitamin D levels checked periodically to tailor dosage. A simple blood test can reveal whether you’re deficient, insufficient or at adequate levels. This is especially important if you spend most of your time indoors.
Vitamin D complements NR effectively. While vitamin D supports immune and muscular function, NR focuses on cellular energy and mitochondrial health. Together, they address different aspects of overall health and vitality.
For better absorption, choose softgels or drops taken with a meal containing fat. Fat-soluble vitamins like D3 need dietary fat to be properly absorbed.
Lifestyle performance stack: NR (Nicotinamide Riboside) and resveratrol
Nicotinamide Riboside (NR) is a vitamin B3 derivative that clinical trials have shown to effectively raise NAD+ levels in humans. Resveratrol is a polyphenol found in grapes and red wine, long associated with longevity mechanisms in research.
Here’s why this combination matters for men:
NAD+ powers cellular function – This molecule is used in hundreds of metabolic reactions, including ATP energy production, DNA repair and mitochondrial function. When NAD+ levels decline with age, so does cellular efficiency.
Energy and performance suffer – Low NAD+ affects everything from workout recovery to cognitive clarity, brain function and even sex drive.
Sirtuins need NAD+ to work – These proteins regulate ageing and metabolism, but they require adequate NAD+ to function properly. Resveratrol activates sirtuins while NR provides the NAD+ they need.
Combining NR with resveratrol creates synergistic support for metabolic health. Human studies have demonstrated amplified effects on insulin sensitivity, reduced inflammation markers, and enhanced blood flow. This makes it a smart ageing-well stack for men in their 30s, 40s, 50s and beyond.
NADBio offers high-purity NR in two forms:
Liposomal capsules – Enhanced absorption through liposomal encapsulation, which protects the active ingredient through the digestive system
Pure NR powder – Flexible dosing for those who prefer to customise their intake or stack with other nutrients
Key quality markers include third-party lab testing for purity and heavy metals, UK-based fulfilment, transparent certificates of analysis, and full regulatory compliance. When selecting men’s supplements, it’s important to choose products that are third-party tested, use high-quality ingredients, and are tailored to individual health needs. NADBio does not sell NMN in the UK because its novel food application remains open with the FSA.
A typical daily routine might look like this: NR in the morning to support energy production throughout the day, resveratrol capsules with breakfast or lunch for optimal uptake, combined with a multivitamin and vitamin D3 for a complete foundation. However, taking too many nutrients in pill form can cause harm, and food is generally the best source for vitamins and minerals.

Magnesium, omega-3s and gut support
Beyond multivitamins and NAD+ boosters, three widely useful categories for men are magnesium, omega-3 fatty acids and targeted gut support. Each addresses common issues that affect energy, recovery and general health.
Magnesium is involved in over 300 enzymatic reactions. It supports muscle function, blood pressure regulation, blood sugar control, sleep quality and stress resilience. Many men don’t get enough magnesium from diet alone, particularly those who train hard or struggle with sleep.
Not everyone absorbs magnesium equally well from different forms. Glycinate and citrate tend to offer better absorption than oxide. If you’re active, stressed or not sleeping well, a magnesium supplement may be one of the most impactful additions to your routine.
Omega-3 fatty acids (EPA and DHA) support heart health, brain function and joint health. Fish oil remains the most common source, though algae oil works well for vegetarians. Men who rarely eat oily fish should consider 250 to 1000mg of combined EPA and DHA daily.
Evidence suggests omega-3s can reduce triglycerides by 15 to 30 percent at higher doses and may support cardiovascular disease prevention. They’re also linked to improved endothelial function, which plays a role in sexual health and blood flow.
Gut support through probiotics or synbiotics may help men experiencing bloating, frequent antibiotic use or high stress. Look for products with diverse strains and appropriate CFU counts. That said, diet remains the foundation for gut health. Fibre from vegetables, whole grains and fermented foods does most of the heavy lifting for your digestive system.
Better sleep, balanced inflammation and improved gut health can indirectly boost energy levels and workout performance. These benefits multiply when combined with an NR-based longevity stack, creating a comprehensive approach to men’s supplements.
Always check for quality markers: third-party testing, clear labelling and absence of unnecessary fillers.
Heart health and supplements: supporting cardiovascular wellness
A strong heart is the cornerstone of long-term health, and the right supplements can play a vital role in supporting cardiovascular wellness for men. While vitamin D is well-known for its impact on bone health, research shows it also contributes to cardiovascular health by helping regulate blood pressure and supporting the function of blood vessels. For men with limited sun exposure—common in the UK—a vitamin D supplement is a smart way to maintain adequate levels and reduce the risk of cardiovascular disease.
Omega-3 fatty acids, especially those found in high-quality fish oil supplements, are another essential tool for heart health. These healthy fats help lower triglycerides, support healthy blood pressure, and are linked to a reduced risk of heart disease. Including omega-3s in your daily routine is especially important if oily fish isn’t a regular part of your diet.
Coenzyme Q10 (CoQ10) is an antioxidant that supports the heart by generating cellular energy and protecting against oxidative stress, which can contribute to cardiovascular disease. Some men, particularly those taking statins, may benefit from CoQ10 supplementation to support heart function and overall energy.
A comprehensive multivitamin that includes essential vitamins and minerals—such as magnesium, potassium, and B vitamins—can further support cardiovascular health. These nutrients work together to maintain healthy blood pressure, support normal heart rhythm, and ensure your body has the building blocks it needs for optimal function.
When building your supplement routine for heart health, focus on a combination of vitamin D, omega-3s, and a comprehensive multivitamin. This trio helps fill nutritional gaps, supports healthy blood flow, and provides a foundation for long-term cardiovascular wellness.
Sexual health support: supplements for male vitality
Sexual health is a key component of men’s overall well-being, and targeted supplements can help support male vitality at every stage of life. Zinc is one of the most important minerals for men, playing a crucial role in maintaining healthy testosterone levels, supporting normal spermatogenesis, and promoting prostate health. A zinc supplement can be especially beneficial for men experiencing low testosterone or concerns about sexual function.
Vitamin D is another essential nutrient for sexual health, as it helps regulate hormone production and supports overall health. Adequate vitamin D levels have been linked to improved sexual function and may help address some underlying causes of sexual dysfunction.
Other nutrients, such as L-arginine (an amino acid) and ginseng, are often used to support blood flow and enhance sexual performance. While some men find these supplements helpful, it’s important to consult a healthcare professional before adding them to your routine, as individual needs and potential interactions can vary.
Remember, supplements work best alongside a balanced diet rich in whole grains, lean proteins, fruits, and vegetables. A healthy lifestyle—including regular exercise and stress management—also plays a significant role in maintaining sexual health and overall vitality.
Best supplements for specific male goals
Optimal supplement choices depend on your age, activity level and specific goals. When selecting men’s supplements, consider products tailored for muscle, performance, and healthy ageing, and always evaluate ingredient quality and third-party testing. Here’s how to approach different priorities:
Muscle and performance requires high quality protein to meet elevated needs (1.6 to 2.2 grams per kilogram of body weight for active men). Creatine monohydrate is one of the most evidence-based performance supplements, with meta-analyses confirming it builds strength alongside protein powder. Add electrolytes to replenish what’s lost in sweat, NR for recovery and energy production, and magnesium for cramp prevention. Young men focused on building muscle may see 5 to 15 percent strength gains from creatine over eight weeks.
Focus and cognitive performance benefits from NR’s support for cellular energy, omega-3s for brain health, and a B-complex including folic acid, pantothenic acid and vitamin b12 for nervous system function. Vitamin B6 and B12 contribute to normal energy release, supporting mental performance. Good sleep hygiene amplifies everything. Optional caffeine can help, but avoid excess sugar from sports drinks and energy products.
Heart and metabolic health calls for omega-3s, magnesium, vitamin D and NR for mitochondrial and metabolic support. A high-fibre diet from whole grains and vegetables complements these supplements. Men concerned about heart disease should prioritise these alongside regular cardiovascular exercise and monitoring of blood pressure.
Healthy ageing and vitality over 50 is where the NR + resveratrol stack truly shines. Add vitamin D3 (with vitamin k for calcium absorption), a multivitamin with B12 and zinc supplement, and potentially CoQ10 after discussing with a healthcare professional. Men should look for supplements that contain zinc and copper to support men’s health specifically. Vitamin c supports immune function and collagen production, while essential vitamins from a comprehensive multivitamin fill remaining gaps.
NADBio focuses primarily on the longevity and energy side of these goals through NR-based stacks. Other nutrients can be layered in as needed based on your specific situation.
Start with one or two key products, such as NR capsules plus vitamin D, rather than adding everything at once. This makes it easier to track which supplements are actually making a difference.
Vitamin B12 is primarily found in animal products like fish, meat, eggs, and milk, so vegetarians and vegans may come up short.
Vitamin B6 and vitamin B12 both contribute to normal energy release, making them important for energy and performance.
Best practices for taking supplements
To maximize the benefits of supplements and safeguard your health, it’s important to follow best practices when adding them to your daily routine. Start by consulting a registered nutritionist or healthcare professional who can help you identify nutritional gaps and recommend supplements tailored to your individual needs. This personalized approach ensures you’re addressing specific deficiencies and not taking unnecessary products.
Choose high-quality supplements from reputable manufacturers that adhere to good manufacturing practices (GMPs). Always follow the recommended dosage instructions, as taking more than needed can lead to adverse effects or nutrient imbalances. Remember, supplements are designed to complement a healthy diet—not replace it—so continue to prioritize nutrient-rich foods and a balanced lifestyle.
Regular blood tests can help monitor your nutrient levels and guide any necessary adjustments to your supplement regimen. By staying informed and working with a professional, you can safely harness the benefits of supplements to support your overall health and well-being, filling nutritional gaps and optimizing your daily routine for long-term vitality.
Safety, UK regulations and how to choose quality supplements
In the UK, dietary supplements are regulated as foods rather than medicines. This means quality and compliance vary significantly between brands. Some products contain exactly what they claim; others fall short or include contaminants.
Third-party testing is essential. When selecting men’s supplements, prioritize those that have been independently verified for purity, potency and ingredient quality, ensuring the absence of heavy metals. Avoid products with proprietary blends that hide exact doses behind vague labels. You should know precisely what you’re taking.
The current UK regulatory position on NAD+ precursors is straightforward: NMN is under an open novel food application with the FSA and cannot be legally sold by any UK supplier until that application is approved. NR, however, is legal and widely used as a compliant NAD+ booster. This is why NADBio focuses exclusively on NR for UK customers.
NADBio adheres to UK and EU legislation, uses reputable manufacturers, publishes lab reports where possible, and avoids exaggerated or misleading claims. Transparency builds trust.
Before combining taking supplements with prescription medications, consult a GP or registered nutritionist. This is particularly important for blood thinners, diabetes drugs or blood pressure medication, where interactions can occur.
Regarding duration of use: multivitamins, vitamin D, NR and omega-3s can generally be taken long term under medical supervision. Very high-dose, single-nutrient protocols should be time-limited unless specifically recommended by a healthcare professional.

Frequently asked questions about supplements for men
Do men and women need different supplements? Yes, there are meaningful differences. Men typically need less iron than women and may benefit more from zinc supplement products for testosterone levels and normal spermatogenesis. NAD+ support is relevant for both sexes, but men often prioritise prostate support and maintaining testosterone within normal ranges as they age. Women of childbearing age have different iron and folate requirements.
How long does it take for NR and multivitamins to work? Water-soluble b vitamins and NR may produce noticeable effects within days to weeks, particularly for energy levels. Some users report improved recovery and reduced fatigue within the first fortnight. Structural benefits like bone health or long-term cardiovascular health take months to develop and aren’t immediately perceptible.
Can I take NR with caffeine or pre-workout supplements? Generally yes, for healthy adults. NR supports energy production at the cellular level and doesn’t directly interact with caffeine. However, if you have cardiovascular concerns, check with a doctor before combining multiple stimulants or supplements that affect blood flow.
Which supplements should I prioritise on a budget? Start with vitamin D (inexpensive and addresses a common deficiency), a solid multivitamin for baseline coverage, and NR for cellular energy support. This core gives you the best return for money spent. Add omega-3s and magnesium as budget allows.
Can supplements replace testosterone therapy? No. Supplements may support normal hormone function, but they are not a replacement for medical treatment. If you have clinically low testosterone confirmed by a blood test, work with an endocrinologist or urologist. Supplements like zinc, vitamin D and NR support prostate health and overall function but don’t substitute for hormone therapy when medically indicated.
Is it safe to take NR long term? Current human data supports the safety of NR at typical doses (300 to 1000mg daily) over extended periods. Clinical trials have shown no significant adverse effects. That said, ongoing medical oversight is sensible, particularly for men with chronic conditions. Periodic blood tests help monitor how your body responds.
Why doesn’t NADBio sell NMN in the UK? NMN currently has an open novel food application with the FSA UK. Until that application is approved, no supplier can legally sell NMN to UK customers. NADBio prioritises regulatory compliance and focuses on NR, which is legal, well-studied and effective for boosting NAD+ levels.
What about hair health and hair support supplements? Normal hair depends on adequate protein, iron (at appropriate levels), zinc, biotin and other nutrients. A good multivitamin covers most bases. Specific hair support products exist but evidence varies. Address underlying deficiencies first before adding specialist products like green tea extract or targeted hair formulas.
