YOUTUBE (Newsmax) - Dr. Jennifer Ashton: The Truth Behind the Scary GLP-1 Brain Disorder Headlines | Greta Wire Thu Oct 1 21:01:12 2026

▶️

A scary GLP-1 headline is making waves, but Dr. Jen Ashton says it leaves out crucial context. In Episode 36 of NEWSMAX’s “Greta Wire,” Greta Van Susteren speaks with Dr. Jennifer Ashton about reports linking widely used GLP-1 medications to Wernicke’s encephalopathy, a rare but serious neurological condition associated with vitamin B1, or thiamine, deficiency. Dr. Ashton explains why the reported cases deserve attention inside the medical community, but argues that the alarming headline amounts to “fear mongering.” She breaks down the numbers, discusses how reduced food intake may contribute to micronutrient deficiencies and shares her professional view on multivitamin use among patients taking GLP-1 medications. The conversation also explores: How different generations of GLP-1 medications work Why eating less may also mean consuming fewer nutrients The risks and benefits of multivitamins Why iron should not be taken casually Calcium from food versus calcium supplements Standing desks, saunas and resistance training Why exercise should become a routine, even when you do not enjoy it This discussion reflects the guest’s views and is intended for informational purposes. Consult a qualified healthcare professional before changing your medication, diet or supplement routine. Watch now, then tell us in the comments: Do medical headlines create unnecessary fear?
