While lemon water is generally considered healthy and hydrating, it's not a direct way to boost white blood cell (WBC) count. However, lemons are rich in vitamin C, an antioxidant that plays a role in supporting a healthy immune system. Vitamin C helps the body produce white blood cells, which are essential for fighting infections.
Therefore, indirectly, consuming lemon water as part of a balanced diet may contribute to a healthy immune system and potentially help the body produce a sufficient number of white blood cells.
