Acetylcarnitine, also known as ALCAR or Acetyl L-Carnitine, is a form of L-carnitine that is produced within the body naturally. It is sold as a dietary supplement and has been known to cross the blood-brain barrier. It primarily increases the production of the important neurotransmitter Acetylcholine thus, improving memory and learning. Moreover, it has been suggested to improve cognition among those with dementia and may have neuroprotective properties among individuals with Parkinson's disease. In studies with rodents, it has been found to significantly reduce neurotoxicity and possibly prevent substances from killing brain cells.

Green Tea Catechins are the major polyphenolic compounds in green tea extracts that have various physiological effects that greatly benefit human health. They are known to be effective antioxidant agents by scavenging free radicals , chelating redox active transition-metal ions, inhibiting redox active transcription factors, inhibiting pro-oxidant enzymes and inducing antioxidant enzymes. Green Tea Catechins also improve blood lipid profile by inhibitng the key enzymes involved in the biosynthesis of lipids and serves to reduce intestinal lipid absorption. Moreover, catechins have been wshown to inhibit proliferation of vascular smooth muscle cells by interfering with vascular cell growth factors involved in arthrogenesis. They also suppress platelet adhesion thus, inhibiting thrombogenesis. In addition to thaat, Green Tea Catechins also regulate vascular tone by inhibiting endothelial nitric oxide as well as preventing vascular inflammation that plays a critical role in the progression of atheroscleoritc lesions.
