Movember starts this Sunday. For the next 30 days, a lot of men will grow questionable mustaches to raise money and attention for men’s health: prostate and testicular cancer, mental health, and suicide prevention. It’s a good cause, and a good prompt to look at your own health.
It also makes a good marketing hook. Expect a November wave of “men’s vitality” multis, prostate formulas, and testosterone boosters. Some men’s health supplements have reasonable evidence. Many don’t. None of them do the things that matter most: catching problems early, managing blood pressure and cholesterol, and getting help when your mood goes sideways.
Here’s how the common options stack up.
Start With What Supplements Can’t Do
Before the shopping list, the honest part. The biggest drivers of men’s health outcomes are not nutrients in a capsule. They are:
- Regular checkups. Blood pressure, cholesterol, blood sugar, and weight are cheap to measure and easy to ignore. Many men go years without a basic physical.
- Screening conversations. When and whether to screen for prostate or colorectal cancer depends on age, family history, and personal preference. That’s a talk to have with a clinician, not something to settle on a supplement label.
- Knowing your body. Testicular cancer is most common in younger men, roughly 15-40. Movember encourages regular self-checks and seeing a doctor about any lump, swelling, or change.
- Mental health. Men are less likely to seek help and more likely to die by suicide. No supplement is a treatment for depression or a substitute for support. If you’re struggling, talk to a doctor or someone you trust. In the US, you can call or text 988 any time.
With that said, a few supplements do earn a place for some men.
Worth Considering (for the Right Person)
Vitamin D
November sunlight in much of the US and Europe is too weak for meaningful vitamin D production, and men who work indoors often run low through winter. Low vitamin D is common, and correcting a real deficiency makes sense.
- Dose: The RDA for adults is 600 IU (15 mcg), rising to 800 IU after age 70. Many men take 1,000-2,000 IU a day through winter. The tolerable upper limit is 4,000 IU/day unless a clinician directs otherwise.
- How: Take vitamin D3 with a meal that contains some fat for better absorption.
- Caveat: Large trials giving vitamin D to people who weren’t deficient have mostly been disappointing for hard outcomes. The benefit is in fixing a shortfall, not in megadosing. A 25(OH)D blood test tells you where you stand.
Creatine
Creatine monohydrate has more consistent evidence than nearly anything else in the sports nutrition aisle. Paired with resistance training, it reliably adds a bit more strength and lean mass than training alone, in younger and older men.
- Dose: 3-5 g/day, any time of day, with or without food. Loading isn’t necessary.
- Expect: A 1-2 kg gain in water weight in the first weeks, mostly stored inside muscle.
- Caution: Creatine raises blood creatinine, which can make a kidney-function test look worse than it is. Tell your doctor you take it. Men with kidney disease should skip it unless their doctor approves.
Omega-3s
Oily fish such as salmon, sardines, and mackerel twice a week is the best-supported way to get EPA and DHA. If you don’t eat fish, a supplement is reasonable.
- Dose: 250-1,000 mg combined EPA+DHA a day covers most general-use cases. Take it with food to reduce fishy burps.
- Mood: Research on omega-3s for low mood is mixed. Some trials of EPA-heavy formulas, around 1 g/day used alongside standard care, show modest benefits. Others show nothing. We cover the details in our omega-3 and mood research brief.
- Caution: Higher doses can add to the effect of blood thinners. Some large trials of higher-dose omega-3s also noted a small increase in atrial fibrillation. Check with your doctor if you take anticoagulants or have heart rhythm problems.
B12 (Mainly After 50)
Absorption of vitamin B12 from food declines with age, and long-term use of metformin or acid-reducing drugs (PPIs, H2 blockers) can lower levels further. If that’s you, ask about a B12 test. The RDA is 2.4 mcg/day. Many older adults do well on 25-100 mcg/day from a supplement, because supplemental B12 doesn’t depend on stomach acid the way food B12 does.
The Prostate Aisle: Mostly Disappointing
“Prostate support” is a huge supplement category. The evidence is thin.
Saw palmetto is the best known. Early, smaller studies suggested it helped urinary symptoms from an enlarged prostate. Later, larger, well-controlled trials found it did no better than placebo, even at high doses. It’s generally well tolerated, but it doesn’t treat or prevent prostate disease. Our saw palmetto research brief covers the full picture.
Selenium and vitamin E are a cautionary tale. A large, long-running trial tested both, alone and together, in tens of thousands of men to see whether they lowered prostate cancer risk. They didn’t. Follow-up data showed the vitamin E group had a small increase in prostate cancer diagnoses. This is one of the clearest examples of a “protective” antioxidant that wasn’t. If you take selenium, stay under the 400 mcg/day upper limit, and don’t take high-dose vitamin E for prostate health.
Lycopene and tomato products show up in many prostate formulas. Observational studies link higher tomato intake with better outcomes, but that doesn’t prove lycopene pills do anything. Eat the tomatoes. Cooked tomato sauce provides more absorbable lycopene than raw tomatoes.
Any new urinary symptoms (getting up at night, weak stream, urgency, blood in urine) need a medical evaluation, not a supplement trial.
Testosterone Boosters: Mostly Hype
Testosterone naturally declines slowly with age, and supplement companies market heavily to that worry. The evidence for most popular ingredients is weak:
- Tribulus has repeatedly failed to raise testosterone in human trials. See our tribulus myth breakdown.
- Zinc and vitamin D only appear to help testosterone in men who are deficient. If your levels are normal, more doesn’t help. Zinc’s upper limit is 40 mg/day, and long-term high doses can cause copper deficiency.
- Fenugreek, tongkat ali, and ashwagandha have some small, short, often industry-funded studies with modest results. They’re interesting but not established.
- Quality risk: Regulators have repeatedly found “natural” testosterone and sexual-performance products containing undeclared prescription drugs or steroid-like compounds. Those can be dangerous, especially with heart medications.
If you have real symptoms such as low libido, fatigue, or erectile changes, get them checked. Erectile problems in particular can be an early sign of cardiovascular issues, and a doctor can test hormone levels properly (a morning blood draw, repeated).
What About a Men’s Multivitamin?
A basic multivitamin is a reasonable insurance policy if your diet is limited. It’s not a performance enhancer. Look for one with no or low iron, since most adult men don’t need supplemental iron and excess iron can build up. Skip formulas that deliver very high doses of vitamin A, vitamin E, or selenium. “Men’s formula” branding often means a higher price and some herbal extras at doses too small to matter.
A Practical Movember Checklist
Instead of buying a stack, use this month to:
- Book a physical if it’s been more than a year or two. Ask about blood pressure, lipids, and blood sugar.
- Ask about screening that fits your age and family history.
- Do a testicular self-check, especially if you’re under 40.
- Check your vitamin D and B12 if you’re at risk of being low.
- Lift something two or three times a week. Add creatine if you want a small, well-studied edge.
- Check in on yourself and your friends. A direct “How are you actually doing?” helps more than a supplement can.
Safety Notes
- Tell your doctor and pharmacist about every supplement you take, especially before blood work, procedures, or new prescriptions.
- Blood thinners: be cautious with fish oil, vitamin E, and high-dose garlic or ginkgo.
- Antidepressants: don’t combine St. John’s wort or 5-HTP with SSRIs or other serotonergic drugs without medical guidance.
- Kidney or liver disease: check with your doctor before creatine, high-dose herbs, or “booster” blends.
Bottom Line
For most men, the supplements with real evidence are short and boring. Take vitamin D if you’re low, creatine if you train, omega-3s if you don’t eat fish, and B12 if absorption is an issue. Prostate formulas and testosterone boosters mostly don’t live up to their marketing, and high-dose selenium and vitamin E look worse than useless. Use Movember to get a checkup, start the screening conversation, and check in on your mental health.
