What If the Cheapest Supplement in the Gym Is Actually Brain Medicine?

from The Habit Healers · host Laurie Marbas, MD, MBA

In 1994, doctors scanned a boy’s brain and found zero creatine inside it. Not low. Completely absent. He had severe intellectual disability, seizures, and almost no language. That case should have changed how medicine thinks about the $0.12/day powder sitting on every gym shelf. It didn’t. Not for decades.In this episode, Dr. Laurie Marbas breaks down the science connecting creatine to your brain, not your biceps. You’ll learn why your brain burns 20% of your body’s energy despite being 2% of your weight, how creatine acts as a rapid-response backup battery for neurons, and why the blood-brain barrier makes brain loading so much harder than muscle loading.We cover the sleep deprivation experiments where creatine prevented cognitive collapse, the 2024 study showing a single dose changed brain chemistry within hours, and the depression trial that doubled SSRI remission rates in women, then got ignored because nobody can patent a molecule that costs twelve cents a gram.Plus: why women’s brains are uniquely vulnerable after menopause (estrogen directly regulates the enzyme that recycles brain energy), what the failed Parkinson’s and Huntington’s trials actually tell us, and the first clinical trial showing creatine can replenish brain energy reserves in menopausal women.This isn’t a story about getting stronger. It’s about whether the most studied supplement in sports nutrition has been misunderstood for 167 years.🔗 Full article with references and downloadable protocol worksheet: https://drlauriemarbas.substack.com/p/what-if-the-cheapest-supplement-inA Big Thank You To Our Sponsors:If you want the best supplement to help you on your plant-based journey, you have to try Complement: https://lovecomplement.com/?aff=62 Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
