                                According to nutritional experts, the unpleasant, sulfur-like smell commonly associated with many B-complex vitamins is primarily due to the presence of thiamine (B1). However, this distinctive odor can be off-putting for many people seeking the health benefits of B vitamins, which are crucial for energy and nervous system health. Fortunately, not all B complex supplements have a strong smell.
