No such materials will give you "energy". For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. Get HPV vaccine. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines

ADHD requires an extensive evaluation with a neuropsychiatrist, psychologist, or psychologist because other mental disorders can mimic it. ADHD can be classified as inattentive, compulsive or both. Not all who have ADHD require a stimulant. Psychotherapy can be beneficial. Treatment options are stimulants (ritalin, concerta, adderall), as well as non-stimulants (bupropion, Strattera, Pamelor).
