I asked specifically about Magnesium L-threonate due to its ability to increase synaptic connectivity (yet to be conclusively reported in humans) and hence gray matter, and Ashwagandha due to its neuroprotective, neurotransmitter-preserving, and cortisol-lowering effects. I take magnesium daily, including the regular dose of Magnesium L-threonate, and my last CMP showed serum levels within range. Maybe super large medical doses beyond even those used for eclampsia would affect heart conduction, or those who take way more than what supplement bottles recommend. I'm not sure what studies have conclusively shown Ashwagandha to be safe only up to 3 months. I get most of my herbal data from Examine.com (PhD academics that analyze data), where they say: "Some case reports have suggested adverse effects such as rash or thyroid dysregulation may occur with ashwagandha use, but the same has not yet been observed by safety studies with larger samples.[38][39][35] Several case reports have also raised concerns regarding the rare occurrence of liver toxicity with ashwagandha use, but similarly, toxicity has not been observed in clinical safety trials. In the reports, liver toxicity was usually reported within 2–12 weeks of ashwagandha use, and liver function returned to normal in all but one case following medical support and ashwagandha discontinuation.[40][41][42][43][44][45] An in vitro study suggested that withanone (one type of withanolide in ashwagandha), may have toxic effects in the context of low levels of the cellular antioxidant glutathione (GSH), which is involved in drug detoxification.[46] However, this research is far from conclusive and the mechanisms underlying this possible adverse effect are unclear."
