My daughter suffered her first concussion at the age of 11, with doctors approval went back to the sport and suffered another 7 months later in a freak accident. With a lot of dr. supervision and rest towards recovery 2 years later she still always feels tired and has constant headaches - not to the point she needs medication; but says they are always there- what she says is her normal now. Wondering what vitamin supplements people have had luck w/ for fatigue, headache and memory troubles (which have improved for her) may be beneficial for her. I have lost sleep over this and don't stop thinking about it. Any advice would be greatly appreciated. Thank you
