I am thinking about buying 2 of these. It's a 30 day total supply of nutrients that'll keep you semi-full and packed with lots of vitamins and some carbohydrates n protein. It's for one person. It'll cost me $45 but it has at least a 10 year shelf life. Each serving (approximately 20 calories per tablet or 240 calories per day) 4g Protein, 30g Carbohydrate, 12g Fat, 3g Saturated, 140mg sodium, 12g Sugars, 4g Protein, Vit A 100%, Vit C 100%, Thiamin (B1)100%, Riboflavin (B2) 100%, Niacin 100%, Vitamin D 100%, Pyridoxine HCL (B6) 100%, Folic Acid 100%, Vitamin B12 100%, Iodine 100%, Panthothenic Acid (B5) 100%, Zinc 100%, Manganese 100%. I figure when SHTF these are better than nothing. It'll keep me alive and if food gets scarce, I can eat what I have and eat a few tabs. And for a 10 year shelf life, I can't lose! Has anyone tried these?
