The key to Grenade® Ration Pack is that it is a " Full Spectrum", daily nutritional supplement that contains everything you need in one convenient, tear off strip. Anyone can put together a basic multi-vitamin/mineral supplement with decent levels of all of the basic micronutrients that the body requires but some people wantmore & some people require more. Let"s face it, athletes, fitness professionals & military personnel ask more of their bodies, creating muscular & oxidative stress & increasing many of their nutritional requirements. Also, it is well-established that there is a lot more to "complete" nutrition than just getting all of your vitamins.
