The Survival Tabs were developed more than 30 years ago for the space program. Because there is zero gravity in space, American scientists theorized that astronauts would have difficulty digesting their food while in orbit.

It’s because of this that they began searching for a food product that would ensure they got the daily nutrition they needed to carry out their missions at a high level, including keeping up their dexterity, stamina and coordination.

The Survival Tabs were the solution to this problem and, since then, they’ve been embraced by adventurers, athletes, rescue professionals, and everyday folks around the world.

Of the theoretical calorie content that any particular food item contains, the normal human body normally utilizes only 30-40% of those calories, meaning that approximately 60-70% of all the food that a normal person eats is unused.

Unfortunately, much of that unused food accumulates in the gastrointestinal tract over many years, causing such residual effects as lack of energy, constant sleepiness and a lack of vitality.

One of the main reasons for these problems is that, when there are residual foods caught in the intestinal tract, the body must send more blood to the digestive system in order to try and digest this unused food, meaning that it uses much more energy to do this than it normally would.
