                                Despite their similar-sounding names, nicotine and nicotinic acid have no functional or biological relationship within the human body, a distinction that has historically caused public confusion. In fact, one is a highly addictive alkaloid, while the other is a vital vitamin for maintaining a healthy nutrition diet.
