We studied the effects of self-supplementation with a drink with ω-3s, antioxidants, and resveratrol on Mini-Mental State Examination (MMSE) scores, macrophage M1M2 phenotype [the ratio of inflammatory cluster of differentiation (CD)54+CD80 and proresolution markers CD163+CD206], and Aβ1–42 phagocytosis in patients initially diagnosed as having MCI or subjective cognitive impairment (SCI). The gene discussed is MRC1; the disease is Cognitive impairment.
