Daily Value The Forgotten Vitamin for Brain Health
4 snips
Feb 12, 2025 Discover the underestimated power of vitamin K for brain health. Recent research links higher intakes of this nutrient to lower levels of neurofilament light chain, a marker for neurodegeneration. Learn which forms of vitamin K are vital for neuronal function and how they might slow cognitive decline. The discussion delves into vitamin K's protective mechanisms, including its role in sphingolipid metabolism and inflammation reduction. Dive into the science behind diet and brain resilience.

Episode notes
NFLC as a Biomarker
- Neurofilament light chain (NFLC), a protein in nerve fibers, is a biomarker for neurodegeneration.
- High NFLC levels correlate with stroke risk, dementia, and age-related cognitive decline.
Vitamin K and Brain Health
- Vitamin K, crucial for blood clotting and bone health, may also significantly influence brain function.
- Different forms of vitamin K exist, including K1 (found in leafy greens) and various K2 subtypes (in fermented foods and animal products).
Vitamin K Intake and NFLC Levels
- A study using NHANES data linked higher vitamin K intake (over 200 mcg/day) with lower NFLC levels in older adults.
- This suggests vitamin K's neuroprotective potential, especially with aging.
