Are there any vitamin supplements that can help with concentration/focus?
Something I could find at Wal-Mart or Walgreens.
Focus Factor is one.... You can order it online from Amazon and have it in a couple of days. I dont know if it is in stores. You can eat healthy foods and get the same benefits though.
Omega 3 supplements, that's help you for focus, memory & concentration. Or you can try for THIAMINE (VITAMIN B1) supplements for memory and concentration.
