Smidge® probiotic powders and capsules have a 24 month shelf life from the date of manufacturing, or the best by date that is printed on the bottom of the bottle. These were tested after 24 months of being refrigerated and unopened and the potency was still at 110% of what was listed on the label. You can expect that the probiotic will retain 100% of its potency for at least 24 months from the date of manufacture, or best by date on the bottom of the bottle.
As long as the probiotic has been stored using our recommendations and kept cold upon receiving, it will be potent and viable, and may be used until the probiotic is gone.
However, suppose the bottle is left unrefrigerated for longer durations of time, of course. In that case, you will begin to see a decline in activity, so it is recommended that the probiotics be kept cold for long term storage. Additionally, it is vital to keep the bottle sealed once opened and use a clean, dry measuring spoon not to linger inside.
