[Q]: For those of us on a low carb diet these little tablets are just the thing.  Two years ago I started cycling again after many years but was having heart arrhythmia after longer rides in high heat.  I was drinking plain water but did a little research and thought electrolytes might be the issue.  Gatorade wasn't an option because it is so loaded with carbohydrates so I looked around for a low-carb alternative.  The "zero carb" sports drinks didn't help so what to do?  One day I ran across these at my bike shop so tried a tube of them.....voila!...problem solved!!  I've shared them with two friends in particular whose problems with leg cramps were resolved while using these.  These guys got it right -- they are superbly formulated and simply work.....

[Q]: I get around a shipment a week all year round from Amazon, and I can not remember ever writing a review. But I am making a point of expressing my anger over this product. I buy lots of tea from many sources and white peony is one of my favorites. The package says it is organic and of the finest quality. It was possibly the worst tea I have ever tasted. In fact, after a couple of pots, I actually threw nearly the whole half pound in the trash. And the price wasn't even that good. I subsequently bought a pound of excellent organic white peony from Whole Foods for less. Whatever they are, this is not a tea company.

[Q]: Local availability of the Plain variety of these crackers has been unpredictable with stores trimming inventory and dropping all but the highest volume SKUs. Buying on subscription makes it affordable and, so far, reliable.
