Lab and selective palette approved!

This is the best price around for electrolyte-flavored water! I drink it to help keep my electrolyte levels up, I can't drink most of the options on the market due to taste sensitivity. Since I started drinking this at home when possible, my labs have gotten so much better!

Bottled ph H2o

When you need to regulate the ph balance, it's easiest to just drink water.. better if it's already balanced water to help. I don't know anything about this stuff but it sure helps me in a pinch

Our Daily Go-To for Great Tasting Water at a Perfe

Living in Houston, our tap water is not the best, so our family goes through a lot of bottled water. We are very happy with this Sam's Club water. The price is absolutely perfect for buying in bulk, and the clean taste is excellent. It is our daily go-to.

Good price

This is a standard for me. Love the larger size and still fit in all cup holders. Taste is great and since they say alkaline is better I continue to purchase.

Great tasting water!

This is a regular buy for us, as this is our favorite water. We enjoy the taste and the large bottle size. When staying hydrated is top priority, this alkaline water works!

Husband loves it

My husband prefers alkaline water so I bought this for him to try. He told me it's the BEST one he's tried, loves the taste and because of the large bottle size, he finds himself drinking more water. It's also really very well priced compared to other brands.

Great taste, half the price

I’m glad I decided to try Member’s Mark Alkaline water. Same great taste at nearly half the price of a more popular brand. I almost didn’t write this review because I thought it might be harder to keep up the stock and being a little selfish I want it available when I want it.

Alkaline Water - Member's Mark

Sam's Club Alkaline (Ionized Hydration) Water is great quality for the price--compared to other waters. The price has remained low enough to be a very good value. It usually appears to be the only label of alkaline waters sold at Sam's Club that sells out first.

GREAT WATER! BUT............

This is great water. But for some reason, some of the water bottles are BROWN at the bottom. I'm not sure if that's a sign of the water being old. Or if the chemicals inside the water have settled to the bottom. In any case, I always check to see if the water is clear at the bottom before purchasing.
