Review: Nice all round - Superb, good value and flavour
Review: Liquids a go go. - Easy to carry, quick to dissolve and not that bad taste wise. There's no weird after taste and it does the job nicely. I also noticed that there's no increase in urine release. I use it as a night drink, or if I'm driving.

## Questions & Answers

**Q: How many mg of Magnesium per tablet is there?**
A: No mineral information per tablet, only vitamin B in mgs.
Contains magnesium carbonate which is not very soluble, so I suspect it has poor bioavailability, BUT it helps my tennis! If you believe in it , it works

**Q: Dear Seller. What exactly is the starch in this product please**
A: I’m afraid that all it says is starch, without anything else.  Other languages on the multi language label only say starch too.  It could be hydroxyethyl starch, that Googling shows is commonly used with potassium chloride in electrolyte resuscitation.  Or they are experimenting with tapioca starch, which, combined with potassium chloride, may reduce sodium chloride (salt) in sausages.  Not a lot of help, but I enjoyed the search.

**Q: Is the lemon one supposed to be salty**
A: Yes, all electrolytes should be salty

**Q: Expiry date?**
A: Food supliments must by law have an expiry date. It infers some degradation over time.

Great rehydration and electrolytes I had atrial fibrillation on and off, the cardiologist said to cut out caffeine and stay better hydrated, i have been having one of these every day in a pint of water, haven’t had any AF since!
