                                While B vitamins are crucial for energy and metabolism, taking high doses, especially of a supplement like liquid B complex, can lead to side effects ranging from mild stomach upset to more serious health concerns. The body is designed to excrete excess water-soluble B vitamins, but overconsumption can overwhelm this process.
