Hi, BS. Flaxseed oil is not that expensive. Just dump it. Barleans is a quality product. The date is there for your protection. No, it may not smell bad or even taste bad, but the problem with flaxseed oil is that it is an extremely fragile fatty acid, one that oxidizes easily when exposed to sunlight, oxygen or heat. When damaged or past the expiration date, what should do you good either does you NO good or turns the corner and starts to do you harm.
BTW, in case you didn’t know it, don’t EVER cook with your flaxseed oil.
BTW #2, you do keep it in the refrigerator, don’t you?
BTW #3, it’s a GREAT supplement to take on a daily basis. (grin)
