We have samples of The Survival Tabs that were produced in 1974-75. They have been stored at room temperature. We test them periodically and have found little, if any, deterioration or loss of vitamin or food value.

We have also used accelerated storage testing at higher than normal temperatures to determine loss of food value and acceptability. Our results showed negligible loss in these areas.

Freezing temperatures will have no effect at all on these tablets.

We would estimate the shelf-life for The Survival Tabs to be 25 years.
