I just found two containers of GRN Vitapower vitamins. I know I purchased these awhile ago. The container is sealed and the vitamins inside are individually wraped and sealed. I opened one container and the vitamins appear normal.. Just wondering the self life of sealed vitamins. Please advise. Thank you.

If they are past expiration date do not take them. Even vitamins can be harmful when expired.

That's the thing, there is no expiration date on them.

How long ago did you buy them?
Usually pills have an expiration date about 2 to 4 years from manufacturing date.

All vitimans should have a code of some sort that would show a date. Are there any numbers on the container
