Summary
Dr. Andy Galpin discusses nutrition and supplementation strategies to reduce the risk of brain injury and enhance brain performance and long-term health. He explains what happens in the brain during a traumatic brain injury (TBI) or concussion - noting these are common in non-athletes as well - and covers science-supported nutrients to reduce injury risk and support recovery. A practical episode bridging exercise science and neuroprotection.
Key Points
- What happens in the brain during TBI and concussion
- Brain injuries are common in non-athletes, not just sports
- Science-supported nutrients to reduce brain injury risk
- Supplementation strategies for brain performance and long-term health
- Nutritional approaches to support recovery after brain injury
Key Moments
Magnesium is involved in over 600 reactions in the body
Dr. Galpin explains that magnesium is involved in well over 600 reactions including cell signaling, ATP production, protein synthesis, neuroplasticity, and memory. Deficiency is associated with type 2 diabetes, metabolic syndrome, hypertension, and headaches.
"magnesium oh my goodness could I go on and on and on about the physiological benefits of magnesium it is involved in well over 600 reactions in your body from cell signaling vascular function ATP production protein synthesis uh neuroplasticity learning memory"
Magnesium drops near neurons after brain injury correlates with severity
There is a well-documented drop in magnesium near central neurons after TBI, and the extent of that drop correlates with injury severity and behavioral disturbances. One study found 400mg of magnesium twice per day reduced post-concussion severity scores within 48 hours.
"there's a well documented drop in magnesium especially near Central neurons after a TBI and the extent of that drop is associated with the severity of the injury and the level of Behavioral disturbances"
Magnesium forms and practical dosing guidance
Galpin notes there is no compelling evidence that any magnesium form (threonate, bisglycinate, malate) is better than another. He takes magnesium at night since most people find it helps with sleep, and notes pumpkin seeds are the highest food source at about 200mg per 100g.
"there is all kinds of forms you've heard of magnesium threate at this point bisglycinate malate and right now I don't know of any compelling evidence to suggest one of those forms is any better than another"
