Andrew Huberman Electrolyte Water: The Secret Formula for Better Focus, Energy & Hydration
September 11, 2025If you're curious about boosting your daily hydration routine, you've probably heard about Andrew Huberman's take on electrolyte water. With so much buzz around health and performance, it's easy to see why his approach has caught attention.
You don't have to be an athlete to benefit from understanding the right way to hydrate. Huberman's recommendations blend science and practicality, making it simple for anyone to support their energy and focus throughout the day.
Who Is Andrew Huberman?
Andrew Huberman is a neuroscientist and professor at Stanford University who studies brain function, behavior, and health optimization. His research focuses on neural regeneration, visual neuroscience, and the biology of stress. He shares practical, research-backed strategies for wellness on his popular podcast, Huberman Lab, which covers topics like electrolyte water, sleep, and performance. You’ll find his advice cited by athletes, executives, and wellness enthusiasts. Huberman integrates complex biology with actionable steps that boost focus, energy, and overall hydration—key topics in his ongoing health discussions.
What Are Electrolytes and Why Are They Important?
Electrolytes are minerals that dissolve in your body's fluids, carrying an electric charge. Common electrolytes include sodium, potassium, magnesium, chloride, and calcium. These minerals support essential processes like nerve signaling, muscle contraction, heart rhythm, and hydration balance.
Your body uses electrolytes to regulate fluid movement between cells, maintain pH levels, and support energy production during physical and cognitive activities. For example, sodium and potassium help muscles function correctly, magnesium aids in energy transfer, and chloride balances bodily fluids.
Sweating, intense exercise, high heat, and illness quickly deplete electrolytes. When electrolyte levels drop, you might experience muscle cramps, fatigue, mental fog, or rapid heartbeat. Replenishing these minerals helps you sustain focus, energy, and overall health—key points in Andrew Huberman’s hydration guidance.

Andrew Huberman’s Approach to Electrolyte Water
Andrew Huberman bases his approach to electrolyte water on current research and direct experience, highlighting practical steps to support hydration and cognitive performance. His method centers on using precise mineral blends and specific intake timing.
Key Ingredients Recommended by Huberman
Sodium (table salt or sea salt) supports nerve function and fluid balance
Potassium (often from potassium chloride or potassium citrate) regulates muscle contraction and heart rhythm
Magnesium (magnesium glycinate, citrate, or malate) assists energy metabolism and calms the nervous system
Chloride (paired with sodium and potassium) maintains osmotic pressure and pH stability
Calcium (included less frequently) supports neuromuscular function
Huberman avoids sugar-heavy sports drinks, opting for simple mixtures of these elemental minerals. You find his recommendations focus on ingredient purity and avoiding unnecessary additives for optimal hydration and performance.
Huberman’s Suggested Ratios and Dosage
Huberman suggests measured doses tailored for hydration efficiency over excess consumption:
| Ingredient | Typical Huberman Recommendation (per 16–32 oz water) | Source Example |
|---|---|---|
| Sodium | 500–1000 mg | 1/4–1/2 tsp salt |
| Potassium | 200–400 mg | Potassium chloride/citrate tablets |
| Magnesium | 60–120 mg | Magnesium glycinate powder |
| Chloride | Provided in salt/potassium source | Sea salt/potassium chloride |
| Calcium | Optional, minimal | Calcium citrate (if included) |
You can consume electrolyte water upon waking, during prolonged focus, or after sweating. Huberman underscores that excess salt may cause gastrointestinal discomfort or higher blood pressure, so you should adjust the amounts to your activity and individual sensitivities.

Benefits of Electrolyte Water According to Andrew Huberman
Andrew Huberman identifies electrolyte water as a crucial element for sustaining hydration, optimizing brain function, and supporting physical performance. You can improve your daily wellness by understanding how electrolytes impact your body’s key systems.
Hydration and Performance
Electrolyte water supports hydration by enhancing fluid absorption and retention, which directly impacts endurance and energy. You gain the following advantages when maintaining mineral balance, according to Huberman:
- Maintain steady muscle function and avoid cramps during exercise, especially in high-heat conditions or prolonged activity (source: Huberman Lab Podcast, episode 70).
- Sustain cardiovascular performance and protect against dehydration-related fatigue.
- Experience better physical recovery, as replenishing minerals—like sodium, potassium, and magnesium—prevents rapid depletion after sweating or intense output.
- Optimize fluid movement between cells, which supports athletic output and daily stamina, with balanced intake of sodium and potassium (see National Academies of Sciences Hydration Report).
Cognitive and Physical Health
Huberman links electrolyte water to greater mental clarity, focus, and stable mood. You experience these science-based effects through regular, appropriate intake:
- Improve cognitive sharpness and decision-making, especially during periods of mental fatigue or concentration (Huberman Lab Podcast, episode 86).
- Reduce mental fog and support neurotransmitter activity, as key minerals like magnesium and potassium influence nerve firing and brain signaling speed.
- Experience steadier mood and lower perceived stress when electrolyte levels remain balanced during long work sessions or after physical exertion.

How to Make Andrew Huberman Electrolyte Water at Home
You can mix electrolyte water at home using Andrew Huberman’s preferred ingredients. This method matches his guidance for balanced hydration, free from unnecessary additives.
Ingredients and Preparation Tips
- Sodium (Sea Salt or Himalayan Salt): Add 1/4 to 1/2 tsp (about 575-1150 mg sodium) per liter of water, adjusted for taste and activity level.
- Potassium (Potassium Chloride or Lite Salt): Include 1/8 tsp (about 450 mg) per liter of water for optimal nerve and muscle support.
- Magnesium (Magnesium Glycinate or Citrate Powder): Measure 200-400 mg per liter of water to help muscle function and cognitive performance.
- Optional - Calcium (Calcium Citrate or Lactate Powder): Add 100-200 mg per liter if you experience cramping or perform intense exercise.
- Water (Filtered or Spring Water): Use 1 liter per batch to dissolve minerals evenly and support absorption.
Stir minerals thoroughly until dissolved. Mix fresh each day for best taste and mineral efficacy. Adjust dosages if you engage in intense exercise, sweat heavily, or have dietary restrictions.

Common Mistakes to Avoid
- Overusing Salt: Excess sodium above Huberman’s recommended range can cause bloating, digestive discomfort, or elevated blood pressure.
- Skipping Key Minerals: Omitting potassium or magnesium leads to suboptimal hydration benefits, muscle cramps, or poor cognitive function.
- Choosing Flavored or Sugary Mixes: Sports drinks with sugar and artificial flavorings introduce unnecessary calories and reduce the electrolyte water’s effectiveness.
- Failing to Adjust for Activity: Using a fixed dose without considering sweat loss, heat, or workout intensity leads to imbalanced hydration.
- Improper Mixing: Leaving minerals undissolved affects absorption rates and taste, limiting effectiveness.
Follow Huberman’s ratios for optimal results when preparing electrolyte water at home.
