I am training for a half marathon.  At the start of my training I wasn't taking cherry juice.  As I increased my long runs each week my knees and hips were so sore.  I started to take this cherry concentrate and ever since then I have felt pretty good.  I take the juice every morning with my breakfast.  It has a very strong flavor but mixes well with apple or orange juice.  The half marathon I'm running in is this weekend and I feel ready for it thanks in part to the cherry juice helping reduce the pain.  This stuff works for me.

This is ridiculous.  The best gourmet ketchup I have ever tasted.  It is pricey, but wow..love this stuff.  It would make a great gift for someone who is hard to buy for but loves their ketchup.  Yummy!

First, I'll give the manufacturer some credit for making a no-additive, sucralose-only product. The problem with this product is: it's just too weak, in flavor that is. 1 gram of this "pure sucralose" tastes about as strong as 1 gram of a Splenda packet, for comparison. If you don't mind spending a lot for a little bit of pure sucralose taste, then maybe this is for you, but cost-conscious customers might want to look elsewhere for a no-carb, non-calorie sweetener.
