The Science
Lux Vita exists because we wanted supplements we’d actually be comfortable taking every day — and recommending to people we love. That meant a much shorter shelf of products, much higher standards, and a lot more honesty.
Our four standards
Sourcing
We tell you where every active comes from. Each ingredient has a documented origin and a paper trail back to the supplier. No country-of-origin secrets, no vague “premium-grade” labels.
Dosing
We use researched amounts of single actives. No proprietary blends, ever. Proprietary blends are how brands hide low doses behind a long ingredient list. We’d rather show you the numbers and let you decide.
Testing
Every batch is third-party tested for identity, potency, heavy metals, microbial load, and (where relevant) solvent residues. Certificates of analysis are available on request and published on each product page as they’re issued.
Honest labels
We say what’s in it. We say what isn’t proven. We don’t promise outcomes we can’t deliver. Where regulation requires it, we say so. Where the science is mixed, we say that too.
The thing no supplement can replace: movement
We sell supplements, so it would be convenient for us to tell you that longevity comes in a capsule. It doesn’t. If you read nothing else on this page, read this: the single most powerful, best-evidenced thing you can do for how long and how well you live is regular exercise. Nothing we make comes close, and we’d rather say so plainly than let you believe otherwise.
What the evidence actually shows
Fitness is one of the strongest predictors of lifespan we have. In a Cleveland Clinic study of more than 122,000 adults followed for around a decade, cardiorespiratory fitness (how well your heart and lungs deliver oxygen during effort) was inversely linked to death from any cause, with no upper limit found. The least fit group had a higher risk of dying than smokers, people with diabetes, or people with heart disease in the same cohort. The biggest single jump in survival came from moving out of the least-fit group into the merely below-average one — you don’t need to be an athlete to collect most of the benefit.
Strength matters as much as stamina. A 2022 meta-analysis of cohort studies in the British Journal of Sports Medicine found that just 30–60 minutes a week of muscle-strengthening activity was associated with a 10–17% lower risk of death from any cause, and lower risk of cardiovascular disease, diabetes and some cancers. Combining strength work with aerobic activity was associated with lower risk than either alone.
Inactivity is a cause of premature death in its own right. The World Health Organization ranks physical inactivity among the leading risk factors for global mortality. Prolonged sitting, independent of formal exercise, is associated with worse outcomes — and even short, regular breaks from sitting appear to help.
The mechanisms are real, not marketing. Regular exercise improves insulin sensitivity, blood pressure and blood lipids; it supports mitochondrial density and function; it slows the age-related loss of muscle mass and bone density that drives frailty and falls; and it is one of the few interventions with consistent evidence for protecting cognitive function as we age. These are the same systems that most “longevity” supplements claim to influence. Exercise moves them further, more reliably, and for free.
How much, honestly
The UK Chief Medical Officers’ guidelines are a sensible floor, not a ceiling: at least 150 minutes a week of moderate activity (brisk walking counts), or 75 minutes of vigorous activity, plus strength work on at least two days a week. If you currently do nothing, going from nothing to something is where the steepest gains are. Consistency beats intensity — the routine you’ll still be doing in five years is the right one.
Where we fit
Our products are designed to sit alongside a life that already includes movement, decent sleep and real food. They may help support energy, recovery and normal function within that context. They are not a substitute for it, and we won’t pretend they are. Start with the walk. Add the weights. Then, if you want to, add us.

How we test
Each batch of finished product is sent to an independent ISO-accredited laboratory. The standard panel is:
- Identity (HPLC or equivalent)
- Potency / active content
- Heavy metals: lead, arsenic, cadmium, mercury
- Microbial load: total aerobic count, yeasts and moulds, E. coli, Salmonella
- For botanicals: pesticide residues
Where a finished-product test result sits outside our internal spec, the batch does not ship. We’d rather be late than wrong.
The compliance footnote
UK food supplements fall under regulation administered by the FSA (Food Standards Agency) and the MHRA (Medicines and Healthcare products Regulatory Agency). Claims must follow EU Regulation 1924/2006 as retained in UK law, and advertising must comply with the ASA’s CAP Code.
What that means in practice: we cannot tell you that any of our supplements will cure, treat, reverse, or prevent any disease — because under UK law, only licensed medicines can make those claims. Our supplements are foods, not medicines. We can describe what they may help support, what the research suggests, and how they’re typically used. We can’t promise specific outcomes.
If you’re under medical care, pregnant, breastfeeding, or taking prescription medication, speak to a clinician before starting any new supplement.
