A member asked:
Is it a bad idea to take expired protein supplements (powder)?
A doctor has provided 1 answer
Yes: Substances, whether grown in a field or created in a laboratory or factory, change over time. They can lose potency, and/or they can lose nutrient value. The expiration date is the outer edge of when the manufacturer will guarantee potency and/or nutrient value. Beyond that time, you may be taking something that will either not have the desired effect or possibly have a negative one.
