Purchased in August 2024.
From website: "In general 12 to 18 months from date of purchase. It's best to keep them cool and out of sunlight for longevity. Most of the minerals are good for many years, but the plant extracts contain amino acids that can bind up, so giving your nutrients a good shake before using is a good idea if they have been sitting for a while."
