This formula combines acetyl-l-carnitine, phospholipids and herbal extracts to promote neural health, cognitive function and memory. Research suggests that acetyl-l-carnitine supports memory in older adults. Phosphatidylserine may be an important cell membrane component critical for neuron function and communication. Research suggests that it promotes healthy neurotransmitter levels and spatial memory. The Ayurvedic herb Bacopa monniera may promote memory as well as mental function and information processing. Ginkgo biloba promotes cerebral blood flow, vascular integrity and healthy red blood cell and platelet function in the brain. Lutein and zeaxanthin are the primary carotenoids in the macula, but have also recently been identified as the primary carotenoids in the brain. Research studies have found a positive association between lutein and zeaxanthin intake, macular pigment density and cognitive function. This association is believed to be due to antioxidant defense and cytokine balance properties, helping to promote neuronal membrane stability and function. Curcumin, resveratrol and lemon balm extracts help to protect neurons from oxidative stress. Additionally, curcuminoids and resveratrol support healthy vascular tissue in the brain by promoting phagocytosis and proteosome activity.
