I would have to disagree with your analysis of the potential benefit of these “Lifecaps” towards providing enough nutrition (along with protein bars and fiber) in a survival situation. The body is essential a biological machine, while vitamins and other supplements may assist in the running of the biological engine (like fuel additives); it is calories (fuel) that make the engine run. A combination of high-quick burring caloric and long-term caloric foods are necessary. The high-quick burning calories provide energy while engaged in high demand activities and for short term thwarting of hypothermia. The slower burning-long term calories provide energy in a slow steady state, so one does not experiences sudden crashes in energy levels.

Just my 2 cents:
