Jump to Section

Organizing your refrigerator and realizing you're out of water? This is the best time to explore the various alkaline water brands out there! Alkaline water has become a popular beverage over the past few years but what exactly is this water? Here are the best alkaline water brands we've tried and tested.

What is Alkaline Water Anyways?

Alkaline water has a much higher pH level than your typical bottled water which has a pH of 7. While there is water that is naturally alkaline when the natural minerals are picked up over time, many consumers drink alkaline water that has been processed. Homeowners may process tap water with reverse osmosis and then use an alkaline ionizer or make sure that water is vapor distilled before adding alkaline minerals.

The Health Benefits

Whether you're purchasing bottled alkaline water or using reverse osmosis, the alkaline that you consume from your favorite alkaline bottled water brand may be just as beneficial as consuming a potassium bicarbonate supplement.

Though there is more research to be done, many claim that when you drink alkaline water, you partake in the following benefits:

  • Help with acid reflux: drinking alkaline water has been shown to help soothe acid reflux because of its high pH level.
  • Increase weight loss: when you drink alkaline water, some say that it increases your metabolism which can lead to weight loss.
  • Reduce high blood pressure and sugar: the alkaline minerals found in this type of water reduce the thickness, stickiness, and viscosity of blood after exercise.
  • Keep you hydrated: drinking alkaline spring water or those found in plastic bottles positively affects hydration after anaerobic exercise.
  • Fight cancer: alkaline waters are believed to help slow down or fight cancer because they can balance the body's pH level.
  • Positively affect bone health: another one of the health benefits of drinking alkaline water includes improving bone health due it its composition of potassium bicarbonate.
