First off, I love the energy and added strength I recieve from taking Map Amino daily. Secondly , what I have noticed when I miss only a week of not taking this supplement, is a decline in my strength doing just daily living-I took a fall due to lack of strength in my legs, proof to me too not skip this again. Hopefully I will experience a quick recovery by taking this daily- I don't want to be without this in my life- being over 60 yrs. old- I have the proof I needed. Thank you for this awesome product!
