Great for chemo
Flavor Name: Mint, Size: 33.8 Fl Oz (Pack of 1)
I ended up ordering this due to hearing mouth sores occurring during chemo. Using it twice a day to keep from getting the sours and it’s working great.

Too expensive, tastes fine
I was worried based on reviews, but I think these taste fine! I don't eat a lot of candy anyway, but sometimes I just need 1-2 pieces to satisfy a sweet/sour craving. These are great since I'm on the Keto diet. They aren't overly sour for sure, but they still have some sourness to them. There's a bit of an aftertaste since they are made with sugar substitutes, but nothing terrible. My only complaint is the price. Way too expensive for the amount you get.

Not bad
The cherry tastes too much like cherry cough syrup. The grape fruit and apple aren't bad. For a no sugar candy for diabetics when you're having a craving, not bad.

I Wouldn’t Call Them Sour
Did I enjoy this candy? Absolutely. Did it meet my expectations? No.
I have anxiety. I’ve heard about the technique of using a sour candy to distract from an anxiety attack. Well, I also have insulin resistance so I have been looking for a sugar-free sour candy which it turns out is a tall order.
Unfortunately, I was disappointed when I tasted these because they really don’t taste sour. While I enjoy the flavors (especially grapefruit) they aren’t sour. A big bummer.
I do think the nutrition for this candy is awesome, though. They have a good amount of fiber and are made with xylitol which is great for oral health.
Overall, I think they are pricey and not necessarily worth the cost considering they are not anything special outside of the nutritional values. Bummer!
