Many factors conspire to rob us of mental acuity as we age. But, scientists have discovered natural agents with the potential to slow or even reverse this once inevitable decline.

Since 1982, Life Extension has offered the multi-nutrient Cognitex formula to protect and enhance neurological function. Over the years, Cognitex has been improved in accordance with the latest research on the underlying causes of brain aging. Newly reformulated Cognitex now contains even more ingredients designed to provide broad spectrum protection against the multiple mechanisms involved in neurological deterioration.

The active ingredients in Cognitex attack the presumptive causes of age-related brain decline at the source. To inhibit the inflammation-inducing enzymes COX-2 and 5-LOX, Cognitex contains pharmaceutical extracts of Nexrutine® and 5-Loxin®.*1-9 Water-soluble quercetin helps improve cerebral blood flow.*10,11 Phosphatidylserine maintains neuronal membrane integrity and guards against cortisol toxicity.* Alpha-glycerylphosphorylcholine helps boost acetylcholine, a critical neurotransmitter that helps protect neuronal structure.*12-16 Vinpocetine enhances circulation and oxygenation to brain cells, improves neural electrical conductivity, and protects against neuron-destroying excitotoxicity.*17-19

Cognitex is available with or without pregnenolone, a hormone that may be especially beneficial to the brain. (Those with existing steroid hormone-sensitive cancers should not take pregnenolone.)20-22

Brain aging is a leading cause of death and disability in the elderly.23-24 The quest to slow brain aging is the reason many people contact the Life Extension Foundation. The antioxidants found in Life Extension Mix and Life Extension Booster protect against free radical damage to brain cells. The Cognitex formula provides nutrients that help maintain healthy cognitive function via additional mechanisms.

Previously, members had to swallow six Cognitex capsules per day, but a reformulation has reduced the number of capsules to only three. The following page lists the various ingredients included in the new formulation of Cognitex.

Just three softgel capsules of the new Cognitex contain pharmaceutical potencies of the following nutrients:

Glycerylphosphorylcholine (GPC)

600 mg


500 mg

Quercetin (water-soluble)

125 mg

Phosphatidylserine (PS)

100 mg


50 mg


50 mg


15 mg

5-Loxin® is a registered trademark of Ph Thomas and Co., Inc.

There are 90 capsules in each bottle meaning that a bottle will last a healthy person one month.
