All LYFE Fuel products have a stamped-on manufacturing date. The average shelf life is about 2 years from the stamped-on date, but it is best to consume as close to the manufacturing date as possible to receive maximum potency. To maintain freshness, we suggest you store LYFE Fuel products in a cool, dry place away from heat, moisture, and direct sunlight. Most importantly, be sure to keep them in a visible place that will serve as a daily reminder to use them!
