Cognitex has been reformulated to take advantage of new developments and ingredients for cognitive health.
The newest ingredients in the Cognitex formula are two standardized wild blueberry extracts that provide the most active constituents found in this health-promoting fruit.
Blueberry anthocyanins are considered natures most potent antioxidants and have demonstrated properties that extend well beyond suppressing free radicals. Pterostilbene is another blueberry constituent that helps maintain healthy lipid and glucose levels in those already within normal range. Importantly, through their unique biological effects; pterostilbene and anthocyanins may help support DNA structure.
The Life Extension Cognitex formulas provides blueberry extracts standardized with both anthocyanins and pterostilbene.
A crucial building block in the brain is phosphatidylserine (PS). In fact, brain tissues are especially rich in this brain nutrient, but aging causes a decline in the PS content of cells throughout the body, which can lead to cognitive decline.* Phosphatidylserine helps the brain use its fuel efficiently. By boosting glucose metabolism and stimulating production of acetylcholine, supplemental phosphatidylserine has been shown to improve the condition of patients experiencing age-associated memory impairment or cognitive decline. Thus, replacing this brain food is essential.
Life Extensions new generation Cognitex formulas now contain a rich PS compound that mimics the naturally occurring PS in the brain. SharpPS Gold™ fortified with omega-3 fatty acids, delivers unique brain-health benefits to help retard the cognitive degeneration so often seen with advanced age. These unique brain nutrients have been extensively studied and may be of tremendous benefit for the aging brain.
More protection against free radicals
The brain is a highly active organ that produces high levels of free radicals from normal metabolism. These free radicals can bombard the fatty membranes of neurons and other brain cells causing premature loss of function. Cognitex contains a number of phytonutrient-based antioxidants that work best in a lipid (fat) rich environment like the brain.
While antioxidant nutrients provide essential free radical protection, many have limited capacity once they have spared an electron to balance a free radical. Cognitex now contains a novel rosemary extract that is rich in carnosic acid, which provides multi-step protection against free radicals in a process called the carnosic acid cascade. At each step of free radical interaction a new compound is formed, which in turn is a powerful antioxidant in itself.
Bioavailable to the brain
Nutritional support for the brain is challenging as a barrier called the blood-brain barrier keeps out toxins as well as beneficial nutrients and drugs. Cognitex contains the grape seed extract Leucoselect® Phytosome™. By pairing one molecule of proanthocyanidins from grape seed extract with two molecules of phosphatidylcholine from soy lecithin in the Phytosome™, the uptake and distribution to target tissues of the grape seed polyphenols is enhanced.
Once in the brain, the polyphenols trap dangerous hydroxyl free radicals that turn fat rancid. These fats make up the outer lipid membrane of trillions of brain cells. These polyphenols also protect blood circulation and oxygen flow to the brain by improving the tone and elasticity of blood vessels.
Molecular size matters
High levels of procyanidins from grape seed extract does not ensure an extract is going to have a beneficial effect on the brain. Polyphenols with higher molecular weight cannot be absorbed. Leucoselect® Phytosome™ contains smaller size molecules for advanced therapeutic activity as the larger molecules are discarded during the extraction process.
A difference you can feel
Taking dietary supplements can often be an act of faith as we often cannot feel what they are doing. Cognitex provides the patented, nonstimulant phytonutrient called Sensoril®. Sensoril® is a proprietary standardized extract of ashwagandha, also known as “Indian ginseng,” and used in Ayurvedic traditional medicine for boosting brain function and alleviating mental fatigue. Advanced extraction practices now allows for a highly concentrated yet balanced brain nutrient. The effects can often be felt immediately with greater alertness and focus but without the jitteriness of stimulants.
Sensoril® also helps modulate the stress response resulting in cortisol excretion. Stress can be very damaging to the brain, especially memory function, and cortisol stimulates the body to release sugar (glucose) into the bloodstream. Elevated levels of glucose can accelerate aging and increase fat storage leading to weight gain, especially in the abdomen. In addition, the stress-modulating abilities of Sensoril® can help stress overeaters especially when it comes to carbohydrate cravings.
