Nick Norwitz MD PhD | StayCurious MetabolismI read a paper. I thought, "this needs to be wrong." So, I tested it on myself. It wasn't...
Nick Norwitz MD PhD | StayCurious MetabolismWhat if sugar isn’t just sugar? New research reveals how fructose may be transformed into alcohol-like toxins in your body, reshaping how we think about liver health, metabolism, and the microbiome.
Nick Norwitz MD PhD | StayCurious MetabolismA physiology-first guide to constipation—covering posture, nervous system tone, diet, supplements, and overlooked causes—to help you stop guessing and start finding what actually works for your body.
Nick Norwitz MD PhD | StayCurious MetabolismA new study in Nature found that memory loss can be transferred via the gut. The culprit? A single species of bacteria that hijacks the nervous system. Here's how it works and what you can do today.
Nick Norwitz MD PhD | StayCurious MetabolismNew human research reveals how gut bacteria and creatine may restore brain energy and improve depression. If you have or know someone with depression, you need to read this.
Substack | StayCurious MetabolismExercise reshapes your blood–brain barrier. New 2026 data reveal a liver-to-brain pathway that may protect against aging and Alzheimer’s at the molecular level.
Dr. Nick | Stay Curious MetabolismThere is a food that has been shown in multiple human randomized controlled trials to improve metabolic health, reduce liver fat, and even drive weight loss independent of calorie intake.
Dr. Nick | Stay Curious MetabolismAlzheimer's may begin not with plaques, but with broken fat cleanup. New research reveals how ApoE4 fails to clear oxidized lipids — and what we can do today to reduce risk.
Dr. Nick | Stay Curious MetabolismA graph showing the relationship between microplastics accumulation in human brain tissue and dementia cases that shifted my perspective on neurological disease.
Dr. Nick | Stay Curious MetabolismPlastic is everywhere 😱 while I do my best to avoid as much as possible (I buy in glass whenever possible), it’s impossible to completely avoid. That’s why I’m super excited about the microplastic binding probiotic from @winnowlabs! This is not an ad, I’m sharing cause I’m so genuinely excited about the product I have decided to become an advisor for the company!
