Unlocking the Truth Behind Alkaline Water: Is It Really Better for Hydration?

Ari Horesh

In today’s health-conscious world, alkaline water has become a hot topic, promising various health benefits, including better hydration. But what does science say? Dr. Andrew Huberman, a renowned neuroscientist, dives into this topic, revealing the real story behind alkaline water and its effects on our bodies.

The Science of pH and Body Regulation

What is pH?

  • pH Basics: pH measures the acidity or alkalinity of a substance, including water.
  • Acidity and Alkalinity: Lower pH values indicate acidity, while higher numbers suggest alkalinity.

Body's pH Regulation

  • Homeostatic Regulation: The body maintains a stable pH in its cells, despite varying pH levels across different tissues.
  • Gut pH Variation: The pH in the gut varies significantly, aiding the growth of essential microorganisms.

Alkaline Water Myths Debunked

"The pH of your body...is strongly, strongly homeostatically regulated." - Dr. Andrew Huberman

The Alkaline Water Claim

  • Common Belief: Alkaline water, with its higher pH, is thought to regulate body pH and offer health benefits.
  • The Reality: There is no substantial evidence that drinking alkaline water significantly impacts overall body pH.

The True Impact of Water pH on Hydration

Hydration and Water pH

  • Acidic Water: Lower pH water may not move as efficiently from the gut to other body cells.
  • Alkaline Water: Higher pH water (7.4 or more) may absorb more quickly, aiding faster hydration.

Immune System and Inflammation

  • Emerging Research: Some evidence suggests alkaline water might influence certain immune cells and reduce inflammation.

Practical Tips for Optimal Hydration

"There are a few things that you can do...that will allow you to increase the absorption rate of water in the gut." - Dr. Andrew Huberman

Effective Hydration Strategies

  1. Temperature Considerations: The temperature of water can affect its absorption.
  2. Water Filtration: Proper filtration may enhance water quality and absorption.
  3. pH Balance: While not essential, slightly alkaline water can be more readily absorbed.

Conclusion: Hydration Beyond the Hype

Dr. Huberman clarifies that while alkaline water can offer some hydration benefits, it's not a necessity for optimal health. Understanding the science behind water absorption and the body's robust pH regulation is key to making informed hydration choices.


  1. Do I need to drink alkaline water for better health?
    • No, your body efficiently regulates its pH, and regular water is typically sufficient for hydration.
  2. Can alkaline water improve cognitive function?
    • While it can hydrate faster, there's no direct evidence linking alkaline water to improved cognitive function.
  3. Is expensive water necessary for good hydration?
    • Not necessarily. Dr. Huberman suggests practical and affordable ways to enhance water absorption without the need for costly alternatives.

In Summary

Dr. Huberman's insights debunk the myths around alkaline water, emphasizing the body's inherent ability to regulate pH and the simple ways to achieve proper hydration. While alkaline water has its perks, understanding the science behind it helps us make more informed choices for our health.
