Do you actually need a multivitamin? And if so, which one? The supplement aisle is full of overpriced pills with impressive-sounding labels. Here’s what matters for men over 40 in the UK specifically — and which products are worth your money.
Should Men Over 40 Take a Multivitamin?
The honest answer: a multivitamin won’t replace a poor diet, but it’s useful insurance for nutritional gaps that are common in busy dads. Research suggests most UK adults are deficient in at least one key nutrient — and deficiencies in vitamin D, magnesium, and zinc are particularly common in men over 40.
A good multivitamin covers the bases without requiring you to buy six separate supplements.
Key Nutrients Men Over 40 Need
- Vitamin D3 (at least 25mcg/1000 IU) — most UK men are deficient, especially October–April. Linked to testosterone, mood, immune function, and bone health. This is the most important single nutrient for UK men
- Magnesium (200–400mg) — involved in 300+ enzymatic reactions. Supports sleep, muscle recovery, and testosterone production. Most UK adults don’t get enough from diet
- Zinc (10–25mg) — essential for testosterone production. Deficiency directly suppresses T levels
- B vitamins (B6, B12, folate) — energy metabolism, nerve function, and mood regulation
- Vitamin K2 — works synergistically with vitamin D3 for bone and cardiovascular health
- Selenium — thyroid function and antioxidant protection
What to Avoid in a Multivitamin
- Underdosed nutrients — many cheap multivitamins contain 10% of the RDA of each nutrient. Check actual doses, not just that an ingredient is present
- Iron (unless you’re anaemic) — men over 40 rarely need supplemental iron and excess can cause problems. Choose an iron-free formula
- Cheap forms of nutrients — magnesium oxide is poorly absorbed; magnesium glycinate or citrate is far better. Cyanocobalamin (cheap B12) vs methylcobalamin (better absorbed)
Best Multivitamins for Men Over 40 in the UK
1. Vitabiotics Wellman 70+ — Best Widely Available Option
Available in Boots, Holland & Barrett, and Tesco. Good range of nutrients at reasonable doses, iron-free, and specifically formulated for men. Around £8–12 for 30 tablets. Not the most sophisticated formula but solid for the price and easy to find.
2. Thorne Basic Nutrients — Best Premium Option
Thorne is a US supplement brand trusted by professional athletes and used in clinical research. Their Basic Nutrients formula uses high-quality, well-absorbed forms of each nutrient and avoids fillers. Available on Amazon UK. Around £35–45 for 60 capsules — pricier but noticeably better quality than high street options.
3. iHerb Own Brand — Best Value for Online Buyers
iHerb stocks a huge range of supplements at prices significantly lower than UK high street. Their own-brand men’s multivitamin and brands like NOW Foods offer good quality at very reasonable prices. Factor in delivery costs for smaller orders.
Should You Just Buy Separate Supplements?
For maximum efficiency, yes — buying vitamin D3, magnesium glycinate, and zinc separately lets you dose each correctly. But a good multivitamin simplifies things considerably for busy dads who don’t want to take six pills.
At minimum, regardless of whether you take a multivitamin: supplement vitamin D3 separately at 1000–2000 IU daily through autumn and winter. This is the single most impactful supplementation decision a UK man can make.
Matt’s Pick
Day to day: Vitabiotics Wellman — convenient, available everywhere, decent formula for the price. Add a separate vitamin D3 supplement (25–50mcg) on top, especially in winter.
If you want the best: Thorne Basic Nutrients. Higher cost but meaningfully better absorbed forms of each nutrient.
