According to Wikipedia, nootropics are drugs, supplements, and other substances that improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals. Many of them are not regulated by the Food and Drug Administration, and some have reported addiction and harm, as well as uncomfortable side effects. These concerns may be behind YouTube's recent decision to delete at least three nootropics channels over the past three days. Motherboard reports: The nootropics YouTubers don't know why YouTube penalized them. YouTube's community guidelines prohibit harmful or dangerous content, including "hard drug use," which seems like the most likely reason. [Ryan Michael Ballow, a YouTuber whose channel "Cortex Labs Nootropics" was deleted] believes it's either "pharmaceutical industry influence" or some other elements within YouTube's leadership decided to target nootropics specifically. "It's all extremely fishy, and demonstrates a continued censorship trend with YouTube," he said in an email. [Jonathan Roseland, another YouTube that recently had their channel "Limitless Mindset" deleted] guessed his channel got flagged because he made videos about kratom, an opioid-like substance that has been linked to deaths and is coming under increased government regulation. Other kratom videos have apparently been removed. But Ballow said he's never posted a video about kratom, and a search for "kratom" on YouTube pulls up countless results, including reviews. Similarly, searching for nootropics, magnesium, aniracetam, oxiracetam, and Modafinil showed no shortage of videos, including reviews.

It's hard to know why the channels were removed since YouTube declined to clarify specifics with the creators and did not respond to a request for comment. YouTube allows creators to appeal enforcement decisions, but Ballow's appeal was rejected. The rejection notice did not clearly state which guidelines were violated, but it pointed to another potential violation. YouTube "included a paragraph that states that if the sole purpose of your YouTube videos is to drive people off of the platform, said videos break the rules," Ballow said. He interpreted this to mean the fact that his videos directed viewers to other websites to buy products.

But the U.S. Food and Drug Administration seems to be dragging its feet on regulating caffeine content in food and drink, because people have different sensitivities to it (abstract). Currently, caffeine-rich products like Monster Energy get around the rules because they're marketed as dietary supplements. 'Caffeine gets cleared from the body at different rates because of genetic variations, gender, and even whether a person is a smoker. For this reason, it’s difficult to set a safe limit of daily consumption on the compound. Physiological differences, as well as differences in the way people consume caffeine, have tied FDA in knots as it has debated how to regulate the substance. ... The toxic level in humans, about 10 g, is roughly the equivalent of imbibing 75 cups of brewed coffee (in 8-oz mugs) or 120 cans of Red Bull over a few hours. But that lethal limit can vary widely from person to person, experts say."
