In the quest for better health and well-being, vitamins play a crucial role in supporting various bodily functions and preventing deficiencies. With so many vitamins available and a plethora of information on their benefits, it can be overwhelming to determine which ones are essential for daily consumption. This article aims to provide a clear and comprehensive guide to the vitamins you should consider including in your daily regimen, outlining their benefits, sources, and recommended dosages.

1. Vitamin A: Essential for Vision and Immunity
