Reviews

Not Worth the Money

"If you dilute the tablets as per instructions, 500 mL. , the flavour is weak and boring. If you dilute with only 250 mL. , then the flavours are acceptable. Biggest problem I have is instructions state only one tablet daily. For me and my output of energy, this is not enough. They are very convenient however in the tubes."

— Dr. M. (3/5)

First time user

"I first purchased ORS on the recommendation of a pharmacist while on holiday in Kent and Dioralyte was yet again unavailable. I have now switched to ORS as they have some flavour but avoid that cheap boiled sweet taste!"

— Mrs S. (5/5)

Love them

"Love the taste, seem to be doing the job"

— Angela S. (5/5)

Not to my taste

"I love concept - so easy to dissolve and take away in your water bottle however the tablets took a while to dissolve and both me and my child did not really like the taste"

— Laura P. (3/5)

Happy with them

"Happy with them"

— Andrew G. (4/5)

I received the hydration bauble

"I received the hydration bauble and a pair of socks with my regular subscription which I really appreciated! Having the opportunity to try the other flavours is great, I normally stick to strawberry but having samples of the full range was a nice surprise. Thank you!"

— Rachel H. (5/5)

Great product. Great company

"ORS tablets are effective, very convenient and come in several flavours. Also, the company is professional was very helpful at resolving a problem I had when I ordered through Amazon. In future I will order directly through the ORS company."

— Peter (5/5)

These aren't for me

"Unfortunately these aren't for me they almost have a sparkling effect which really messed with my stomach acid. I can imagine some people would prefer the flavour of these then others but unfortunately these just aren't for me"

— Lianne A. (3/5)

"Very nice, does what it says!"

— David (5/5)

Insane

"Amazing!!!"
