I looked at the Survival tabs and it is a little confusing.

One serving (12 tabs) supplies 100% of most of your daily requirement of minerals and vitamins. Good.

One serving supplies 10% of your daily value of carbs. Hmm, so you need 10 servings per day to get 100% of your daily value. That would 120 tabs or 2/3 of a bottle. They claim you only need one serving per day.

I think I would still be very hungry.

Oh, and they are $39.95 a bottle.
