Good for PD: Vitamin A, Carotenoid

Carotenoids (alpha- and beta-carotene) are precursors of vitamin A in human. Egg yolks, organ meats, and milk are rich sources of vitamin A, while carotenoid rich diet includes carrots, sweet potatoes, and peaches, as well as other fruits and vegetables. Previously, vitamin A and beta-carotene were shown to inhibit alpha-synuclein fibril formation and destabilize formed fibrils in dose-dependent manner in vitro [6]. While several human studies did not identify a link with vitamin A and PD [7–10], Miyake et al. found a protective effect of beta-carotene in PD (Parkinson’s Disease) in a Japanese population

Good for PD: Vitamin B

Vitamin B complexes are found in meat, fish, cereal, dairy products, and some vegetables (i.e., potato) and fruits (i.e., banana). Although there are several types of vitamin B, the focus of this discussion is on vitamin B2 (riboflavin), B6 (pyridoxine), B9 (folate), and B12 (cobalamin).
