Alzheimer’s disease is an irrevocable, progressive brain disorder that gradually destroys
memory and cognitive skills. One of the extensively studied methods of preventing Alzheimer’s
disease (AD) progression is by providing a nutritional diet. Several reports have shown that intake
of nutritional elements as huperzine A, ursolic acid, vitamins etc., can directly influence pathogenesis
of AD. Surprisingly, the occurrence of metabolic disorders due to an unhealthy diet has been
known to be a major environmental cause of AD. It has been noted that AD severity can be controlled
by supplementing dietary supplements containing huge amounts of health-promoting ingredients.
These elements promote cell health, regeneration, and the anti-aging process that specifically
interrupt the pathogenic pathways in AD development. Fortunately, incorporating changes in the
nutritional content is inexpensive, easy, acceptable, safe, effective, and in most cases, free from major
adverse events. Many nutritional phytoconstituents such as flavonoids, alkaloids, and terpenoids
are still being evaluated in the hope of identifying a successful therapy for AD. This review
discusses the therapeutical potential of several key nutrients that have been researched for
treating AD treatment and the method of their neuroprotective intervention.
