But chronic, unexplained symptom presentations involving fatigue, brain fog, joint pain, immune fragility are exactly what functional nutrition is designed to address at the root
A few points on Vitamin B12 deficiency: Vitamin B12 (cobalamin) is important for cellular metabolism (DNA synthesis), mitochondrial metabolism as well as neuronal health
This process involves both molecular and morphological changes in the astrocytes, including increased expression of GFAP, vimentin and nestin, uptake of excitotoxic glutamate, protection from oxidative stress by the production of GSH, neuroprotection by release of adenosine, degradation of amyloid-beta peptides, facilitation of blood-brain barrier, increased formation of gap junctions between astrocytes, formation of scars and, in some cases release of inflammatory cytokines, including tumor necrosis factor- (TNF-), and production of ROS [3,35,38-40]
