Neurodegenerative diseases such as Alzheimer's and Parkinson's are marked by neuronal loss due to oxidative stress, neuro inflammation, and lipid dysregulation. Medium-chain triglyceride (MCT) oil, particularly rich in caprylic acid (C8, 56%) and capric acid (C10, 43%), has shown potential neuroprotective effects through its antioxidant properties, cholinesterase inhibition, and lipid-lowering benefits. OBJECTIVES: This study aims to evaluate the neuroprotective effects of ORGAHEAL medium-chain triglyceride (MCT) oil by assessing its antioxidant activity, cholinesterase inhibition, and lipid-lowering effects in vitro. MATERIALS AND METHODS: Antioxidant activity was measured using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and nitric oxide scavenging assays. Cholinesterase inhibition was studied through enzyme kinetics with Lineweaver-Burk and Dixon plots. Lipid-lowering effects were analyzed in 3T3-L1 adipocytes using Oil Red O staining and triglyceride quantification. RESULTS: MCT oil exhibited antioxidant activity in DPPH and nitric oxide assays (IC50: 6.15 mg/mL and 29.87 mg/mL) and non-competitive inhibition of acetylcholinesterase and butyrylcholesteraseE (Ki: 31.01 mg/mL and 24.86 mg/mL). It reduced lipid accumulation and triglyceride levels in 3T3-L1 cells, potentially enhancing neuronal health by lowering oxidative damage. CONCLUSION: MCT oil, with caprylic acid (C8) and capric acid (C10), offers neuroprotective benefits through its antioxidant, cholinesterase inhibitory, and lipid-lowering properties. Further in vivo studies are needed to confirm its therapeutic potential.
