Vitamin C's Role in Brain Redox Balance and Cellular Health
Dr. Kumar’s Take
This study shows how vitamin C moves into cells and keeps the brain’s redox balance in check. It highlights key transporters and links vitamin C levels to neuron health. For best support, focus on vitamin C–rich foods like oranges and bell peppers or consider a supplement if needed.
Key Takeaways
✔ Two main transporters, SVCT1 and SVCT2, control vitamin C uptake in the gut, kidney, and brain.
✔ Vitamin C helps neurons grow, makes key neurotransmitters, and defends against oxidative stress.
✔ High brain vitamin C supports learning and memory in animal models but human dementia trials are inconclusive.
