It's impossible to definitively say which single tablet contains all vitamins without an exhaustive list of every multivitamin available and their specific formulations. However, certain multivitamins are formulated to provide a comprehensive range of essential vitamins and minerals.
The reference provided highlights the "Centrum Adult 50+, World's No. 1 Multivitamin," which contains Calcium, Vitamin D3, and 21 other nutrients. While impressive, the reference doesn't explicitly state that it contains all known vitamins. It focuses on supporting overall health, strong joints, and heart health.
Therefore, while many multivitamins aim to cover a broad spectrum of vitamins, verifying that a specific tablet contains every known vitamin requires a detailed examination of the product's ingredient list. Always consult the product label or manufacturer's information.
