One A Day Proactive 65+ Multivitamin

One A Day is a widely recognized brand of multivitamins tailored to various age groups and nutritional needs. Originally launched in the United States in the 1940s, the brand was developed by Miles Laboratories. It became a household name by simplifying daily nutrition into a single tablet, moving away from complex dosing regimens.

Today, the brand is owned by Bayer, a German multinational pharmaceutical and life sciences company. While the brand has deep American roots and continues much of its manufacturing and distribution within the United States for the North American market, ultimate corporate strategy and ownership are managed from Bayer's headquarters in Germany. The Proactive 65+ variant is specifically designed to support the nutritional requirements of seniors, focusing on bone health, joint health, and energy metabolism.
