It seems like there is a mix-up in the information provided. The text you shared does not relate to Supplements, Vitamins, or any specific person like Louvenia Yocum. It appears to be a promotional email about a lifetime API access offer from ARSource, which may not be relevant to the initial inquiry.
However, I can help you search for information related to potentially harmful supplements or vitamins, as well as any legal issues associated with them. I will begin by researching recent cases or incidents involving defective or harmful products in the supplement and vitamin industry. Let me gather relevant information for you.
