9 Hydration Claims Arizonans Pay Extra for and Shouldn’t

Maricopa County’s public health department confirmed 150 heat-related deaths by early September 2026, a death toll running 97% ahead of the same point last year.

Heat like that drives a lot of bottled hydration sales, and an entire industry competes for Arizonans’ money.

Some of what it sells is unnecessary.

These are the hydration claims Arizonans pay extra for but probably shouldn’t.

Note: This is general information, not medical advice. Guidelines are subject to change, so talk to a doctor about your situation.

1. IV Hydration Bars

Intravenous (IV) hydration bars have opened in wellness studios and strip malls across the country, including several now running in Phoenix and Scottsdale.

A basic session costs more than $150, and a specialized drip can run up to $1,000.

Cleveland Clinic says the evidence behind these drips is thin for anyone who isn’t already dehydrated or sick.

Hydration clinics largely operate without the oversight a hospital IV line gets.

This isn’t a miracle cure.

A body that’s mildly thirsty absorbs fluid through the gut just fine, so a $150 needle skips a step the stomach was already handling for free.

The same clinic lists infection, bruising, and vitamin toxicity among the risks.

2. Alkaline Water

Alkaline water lines drugstore and grocery shelves at a markup over the plain bottle next to it, sold on the idea that a higher pH hydrates the body deeper.

Registered dietitians at Cleveland Clinic say science doesn’t support alkaline water’s marketing over plain water.

Stomach acid neutralizes the water’s higher pH almost the moment it’s swallowed, well before it could reach anywhere a hydration or digestion claim would matter.

The body handles this on its own.

Same water, different price.

Bottled alkaline water routinely runs several dollars a bottle for water that reaches your gut exactly the way tap water does.

3. Hydration Multiplier Powders

A University of Washington dietitian’s take on hydration multiplier powders is blunt.

The average person doing about an hour of casual activity can skip them and just drink water instead.

Liquid I.V.’s product page still promises to hydrate faster than water alone and pack in three times the electrolytes of a leading sports drink, at around $1.50 to $1.75 a packet.

Save your money.

Only true endurance efforts, like marathon training or an Ironman, are where the dietitian says the extra electrolytes earn their keep.

Casual walking, gardening, and running errands all fall well inside the ordinary hour of activity the dietitian says needs nothing extra.

4. Vitamin-Enhanced Water

Vitamin-enhanced water costs $1.99 for a 20-ounce bottle at Target, marketed as a smarter hydration choice on labels reading “vitamins + water = all you need.”

That bottle carries about 120 calories and roughly 32 grams of sugar, close to eight teaspoons, according to the advocacy group that sued over the claim.

Vitamins don’t cancel out sugar.

That mismatch was serious enough that a 2016 class-action settlement forced the maker to print “sweeteners” and the calorie count on the front of the label.

Reading the actual ingredient label instead of the front-of-bottle marketing catches the gap fast, and a plain glass of water plus a multivitamin costs far less than $1.99.

5. Premium Coconut Water

A bottle of premium coconut water runs about $2 at Target, even at a multi-buy discount, marketed as nature’s sports drink for hydration.

Even a 2012 study funded by one of the biggest coconut water brands set out to test coconut water against plain water and a sports drink.

Plain water performed just as well as both for hydration during exercise.

The data disagreed.

Testers in that same study reported more stomach upset drinking coconut water instead of plain water.

Coconut water still tastes good and carries potassium, but paying extra for it as a hydration upgrade over tap water doesn’t hold up.

6. Hydrogen-Infused Water

Pay close to $4.50 for a bottle of hydrogen-infused water at major retailers, and the extra buys a promise of antioxidants and better hydration from the added gas.

MD Anderson Cancer Center says the research behind that pitch remains early and limited, not the solid evidence it would take to beat a regular glass of water.

You don’t need the hydrogen.

A body absorbs whatever is safe to drink, hydrogen or not, so the premium buys marketing more than any measurable benefit.

7. Sports Drinks for Errands

Sports drinks promise hydration for a quick errand or a short walk nearly as often as they promise it after an actual workout.

A 12-pack of 12-ounce bottles runs about $8 at Target.

Harvard’s Nutrition Source calls sports drinks “usually unnecessary” for children doing routine or play-based activity.

Any hydration edge they offer waits for exercise that turns vigorous and runs past an hour of heavy sweating.

That guidance is written for children, not the errands and short walks that push sports drinks on adults, but the sugar count still carries the argument.

A 12-ounce bottle carries close to 21 grams of sugar, not far behind a can of cola’s 39 grams.

That’s a sugary soda.

Harvard’s researchers also point to celebrity endorsements for pushing the drinks on young athletes who are doing nothing close to an hour of vigorous exercise.

Grabbing a sports drink on the way to run errands trades convenience for sugar the body never needed for that walk.

8. Premium Bottled Water

Premium bottled water brands lean on words like pure, natural, and glacier-fed to imply better hydration than the tap.

University of Connecticut researchers found those beliefs come mostly from advertising, not the water.

Much of the bottled water on shelves is just filtered tap water sold back at a markup.

One Virginia water conservation agency says bottled water can run 240 times more per gallon than tap, and sometimes thousands of times more.

Pricier doesn’t mean safer.

That same Virginia agency cites Environmental Protection Agency (EPA) figures showing municipal water systems meet safety standards on average about 90 percent of the time every year.

Bottled water isn’t required to clear that same federal benchmark.

The agency also cites a separate review by the Natural Resources Defense Council (NRDC) that found a third of bottled brands tested violated state or industry water-quality standards.

NRDC is an environmental advocacy group, not a federal regulator, so its findings stand apart from the EPA figures above.

Even a brand that adds electrolytes says so on its label: Coca-Cola’s smartwater lists “electrolytes added for taste,” not for any hydration boost.

9. Smart Water Bottles

Smart water bottles pair an $80 price tag with an app that tracks hydration toward a personalized daily goal.

Mayo Clinic offers the same guidance for free: Drink when thirsty, and check that urine runs clear to pale yellow.

That test costs nothing.
