Toxicology Reports
They may have serious side effects, including possible thyroid tumors

Although large language models have been shown to blunder on occasion (citing, for example, journal articles that do not exist), they have proved remarkably adept at a range of medical examinations, outscoring human physicians at qualifying examinations taken at different stages of a traditional medical training.34 These have included outperforming cardiologists in the European core cardiology examinations, Israeli residents in their internal medicine board examinations, Turkish surgeons in the Turkish (theoretical) thoracic surgery examinations, and German gynaecologists in the German obstetrics and gynaecology examinations.4567 To our great distress, they have even outscored neurologists like ourselves in the neurology board examination.8 In a few domains, such as the Royal College of Radiologists examination, the Iranian periodontics examinations, the Taiwanese family medicine examinations, and the American shoulder and elbow surgery examinations, human physicians still seem to have the upper hand.9101112 However, large language models are likely to conquer these domains as well (especially as the aforementioned studies examined GPT 3.5, an older model now considered outdated)

Ascorbic Acid has shown to help protect cells from damage, which can support immune system health
The same corresponds to the effect of age and aging on the brain barrier functions and the related effects of Se and selenoproteins ( Many studies indicate the critical importance of the exact chemical speciation of essential trace elements (Templeton et al., 2000) in determining their biological activity (Michalke et al., 2018)
