Blood loss, especially from dialysis, infection, inflammation, and malnutrition, is another contributing factor
The rest comes from dietary sources, predominantly red meat, dairy products, and fish

Increasing NAD + by supplementing NR can remarkably normalize DNA damage, p-Tau, synaptic transmission and neuroinflammation, improve the ability of motor function, memory and learning and increase the activity of SIRT3 in the brain
It proposes that the accumulation of -amyloid (A) peptides in the brain is one of the main factors leading to AD, which further causes early damage to dendritic and synaptic, thus leading to neuronal dysfunction [9]
