What Makes a Food “Super” for Energy and Immunity?
Superfoods earn their title through their exceptional nutrient density and bioactive compounds that support vital bodily functions. When it comes to boosting energy and immunity, the best superfoods share several key characteristics:
- Rich in essential vitamins and minerals that support energy metabolism
