Can LOW b12 cause dementia (brain fog), anxiety, depression? Can LOW B12 make you go crazy?

Some high vit B12 foods include: fermented dairy, egg yolk, beef, fish, lamb. High vit b12 foods are essential for a healthy microbiome and for physical and mental wellness. Antibiotics and parasites will destroy the gut microbiome, and also reduce vit B levels. Parasite-overload, iron-overload, low bioavailable copper and low vitamin A (retinol) all go together and lead to low vit b12 levels.
