Supplement capsules and tablets are often made from gelatin (animal-derived), hydroxypropyl methylcellulose (HPMC, a synthetic polymer), or titanium dioxide. Supplement bottles are typically plastic. The supplement industry has less regulatory oversight than pharmaceuticals, and many products contain undisclosed additives.
Why We Rated It This Way
One A Day contains titanium dioxide — a whitening agent banned in food products in the European Union due to genotoxicity concerns. The artificial colors and synthetic fillers add additional chemical burden for a daily supplement.
