If these thoughts are becoming all too frequent, you're not alone. Most people over the age of 40 experience some normal age-related memory impairment. But this is not the same as Alzheimer's disease.
Although most scientific research has focused on Alzheimer's and other, more serious diseases of the brain, ginkgo has been shown to improve mental function in people with mild age-related memory impairment.
Six small double-blind placebo-controlled studies have shown the positive effect of ginkgo on memory loss. Interestingly, 120 mg of ginkgo extract appears to work as well as 240 mg daily. Most improvement took between 6 to 12 weeks, but some people showed improvement with a single dose!
Historically, ginkgo was thought to work by simply improving blood flow to the brain, but recent research has revealed additional positive effects. Ginkgo appears to stimulate and protect special nerve cells as well.
Don't waste your money on the non-extract forms found in many drug stores and supermarkets because they're usually not potent enough. All the studies used a standardized extract of ginkgo that contains 24% ginkgo-flavone glycosides and 6% terpene lactones which are considered the active and effective constituents of ginkgo. Lindberg Ginkgo contains 60 mg of ginkgo biloba leaf extract in each capsule standardized to the same level as the ginkgo in the studies.
The only caution is to consult your doctor before taking ginkgo if you are on any blood-thinning medication. Remember, exercise, eat right, and don't forget your ginkgo!
