In fifth place - and by some distance - is a supplement that, despite being the world’s bestselling multivitamin, is one we strongly advise avoiding.
While it technically covers all 13 essential vitamins and includes most key minerals, Centrum Advance Adults multivitamin is seriously undermined by the presence of multiple harmful and controversial additives. Far from offering peace of mind, this product raises red flags for anyone concerned with long-term health and ingredient safety.
At first glance, it might seem reasonable: it’s free from common allergens such as gluten, lactose, and nuts. But these surface-level positives are swiftly eclipsed by the sheer volume of problematic ingredients. The supplement contains no fewer than nine food additives (E numbers), including artificial colouring E132, known to trigger asthma in sensitive individuals, and E321 (butylated hydroxytoluene), a controversial preservative linked to cancer risk. Most alarmingly, it includes Titanium Dioxide (E171), a whitener banned in the EU since 2022 after being classified by the European Food Safety Authority (EFSA) as genotoxic—meaning it can damage DNA and increase the long-term risk of cancer, neurodegenerative conditions like Alzheimer’s and Parkinson’s, and autoimmune diseases. This is not an ingredient with a safe threshold—even trace amounts can be dangerous when taken consistently over time.
The quality and safety of the supplement are further called into question by its lack of FDA approval (despite being a US brand), and concerning manufacturing practices, with products made in locations such as Puerto Rico, Pakistan, and China—outside the hygiene and quality controls typically applied to UK or EU supplements. With no vegan or vegetarian certification, no money-back guarantee, and a low dose of vitamin K below the required daily minimum (just 40%), it's clear this product does not prioritise the well-being of its users.
Despite its popularity, this supplement's reputation is overshadowed by mounting controversy and expert concern. The presence of carcinogenic and genotoxic ingredients makes it a genuine health risk, especially if taken daily and long-term. It’s a textbook example of why market dominance doesn’t equal quality, and why label-scrutiny is essential when choosing a multivitamin. For anyone serious about protecting their health, this is one to leave firmly on the shelf.
