I started a week ago ,im 58 . The searching is over . My energy is up ,I have a farm loaded with animals and I enjoy them all but when I'm weak a tired it's not so fun. But this vitamin has blown my mind .I even get along better with my husband. Please at least try ,they have taken this out of our food. We need all of these to live our best life .thank you envitamin for giving me my life back . God bless you
