Not hype. Just evidence. We looked at UK sales data, NHS guidance and peer-reviewed trials to find five supplements older adults are genuinely buying — and whether the science supports the spend.
NHS advice is clear: everyone in the UK should consider vitamin D in autumn and winter. Adding K2 is popular because it may help direct calcium to bone rather than arteries. Read the full evidence review.
Still the most bought longevity supplement in the UK. Evidence is strongest for cardiovascular health and triglyceride reduction, not reversal of ageing. Quality varies enormously — check EPA/DHA per capsule, not just "1000 mg fish oil."
Older adults use it for sleep and muscle recovery. Magnesium glycinate is better tolerated than oxide and has reasonable absorption data. See our UK buyer's guide.
Skin and joint claims dominate marketing, but the best trials show modest improvements in skin elasticity and joint discomfort after 8–12 weeks. Marine and bovine collagen both work; type I and III are most relevant.
Popular with people on statins and those focused on heart health. Evidence for statin-related myalgia is mixed, but CoQ10 has a long safety record and reasonable cardiac-energy rationale. Read the UK evidence review.
