Does gingko biloba increase the serotonin level in the brain? can it help a person with attention deficiency issues and also some anxiety?

Good question: No one really knows. Most who recommend it are just guessing or using testimonial evidence .It is a nutritional supplement....Not approved for treatment of any of the things you stated by fda...When you use these products you are experimenting on yourself...See your primary care physician..

Agree with Dr. S: Ginko is not likely to help. Do consult your doctor. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/.
