LifeCaps does work!
My dad is a 52 year old avid hiker. He normally eats a huge breakfast before hiking and packs a lot of food just to keep his energy level up. Recently he went on a 19 mile hike packing nothing but LifeCaps, water, and an emergency sandwich that I, as the skeptic, made him pack “just in case”.
He took a LifeCaps every few hours or so and of course drank lots of water. He made the 19 mile hike in record time and stated that he felt great. He sure acted as if he felt great! At the end of the hike he fed the sandwich to his German Sheperd JoJo, obviously mocking me for making him pack it in the first place. 
Anyways, after seeing it work for my dad on his hike and being a mother of two young children I firmly believe that EVERYONE should at least have 1 bottle of LifeCaps in their car just in case something happens and food is not readily available.
