Is it ok or harmful to drink expired protein powder(Pro-Nos French vanilla). I have some Pro Nos I want to start drinking again with V-8 fushion and it expired 6-09 or say on the bottom best by 6-09. I do not want to get sick or not have it be effective as I using it to substite for a meal.
So do you drink expired protein powder?
First, let me say that my degree is in Food Science and I work in food protection for a steady paycheck...
If the container hasn't been opened it could be ok. Date marking is really a marketing tool; conditions it was stored in is more important. Either way, it won't make you sick, but the quality of it will degrade and the label won't really be accurate. If it has been opened, grab a scoop of it and see if there is what looks like "static electricity" causing the powder to cling to the outside of the scoop. If so chuck it.
If it were me, I'd chuck it. I like to eat good food and take good supplements.
