I used to take the regular strength Vitality capsules, and they worked just fine for me. My husband needed the extra strength, which worked well for him. Since the new branding, I need to take the extra strength capsules and sometimes they are just not enough, so I need to take an extra one. My husband takes 2 of the extra strength a day. The combination of the lower effectiveness and the increase in price make them VERY expensive. Not sure if I will continue with them.
