Review on NutriBiotic Keto Friendly Processed Chemicals Nutrient by Britney Matthews

I've been using this in smoothies for many years and love its mild flavor that goes with anything it's mixed with. I recently had to send two back because they had a rancid smell and taste. I usually use them every three weeks, so I knew something was wrong by the smell as soon as I opened them. I tried it too, but it tastes very sour. I immediately ordered another one, but it was the same story. Not sure if it was a bad batch but both had the same batch number: LT 35617-4 with EXP 1/21. Either that or the recipe has changed for the worse. I hope it's just a bad batch and I'd love to keep buying it but I can't right now. UPDATE: They appear to have fixed this and reversed their recipe/process so there is no longer a rancid taste. The last 3 I bought have gone back to normal. The ones I received have a big sticker on the side that says EXP07/2021. Thank you!
