How much water to drink per day?
Formula, schedule and tips
for Kangen users

Most of us drink too little water — not because we do not want to, but because we do not know when and how much. Learn a simple formula and a ready daily hydration schedule.

A question I hear often: “Why do I need an ionizer when I can drink regular tap water?”

Regular water — whether tap or bottled — consists of H₂O molecule clusters of 15–26 molecules. These clusters are too large to efficiently penetrate through cell walls. Cells absorb such water at roughly 15% efficiency.

Kangen Water, through the electrolysis process, forms micro-clusters of just 5–8 molecules. These smaller clusters pass through cell membranes much more easily — absorption efficiency reaches approximately 95%. This means that by drinking Kangen Water, you hydrate your cells 3 times more effectively than with regular mineral water.

A question I hear often: “Why do I need an ionizer when I can drink regular tap water?”

Regular water — whether tap or bottled — consists of H₂O molecule clusters of 15–26 molecules. These clusters are too large to efficiently penetrate through cell walls. Cells absorb such water at roughly 15% efficiency.

Kangen Water, through the electrolysis process, forms micro-clusters of just 5–8 molecules. These smaller clusters pass through cell membranes much more easily — absorption efficiency reaches approximately 95%. This means that by drinking Kangen Water, you hydrate your cells 3 times more effectively than with regular mineral water.

Practical effect? Less feeling of “fullness” after drinking water, faster post-workout rehydration, better skin condition, and more energy throughout the day.

Watch out for diuretic beverages

Coffee, tea, carbonated drinks, fruit juices with added sugar, and alcohol are diuretic — meaning the body loses more water through them than it absorbs. If you drink coffee, you should supplement with approximately 150 ml of clean water per cup. Coffee brewed with Kangen Water is less diuretic and tastes better — less bitterness, richer aroma.

Important Note on Starting with Kangen Water

If you are starting your journey with Kangen Water, for the first 1–2 weeks drink pH 8.5, then pH 9.0, and only after another two weeks move to pH 9.5. Too rapid a transition to strongly alkaline water may cause mild detox symptoms (headaches, fatigue). This is normal — the body is cleansing accumulated toxins.

Why Does Kangen Water Hydrate Better?

Frequently Asked Questions

How much water per kilogram of body weight should I drink daily?
According to Dr. Philip L. Goglia's formula — 0.03 liter per kilogram of body weight. A person weighing 60 kg should drink 1.8 liters a day, an 80 kg person — 2.4 liters, and 100 kg — 3 liters. With physical activity or illness, increase the dose to 0.044 l × kg.
Can I drink Kangen water daily without limits?
Kangen water, like any water, should be drunk in reasonable amounts. Excessive water intake (above 5–6 liters a day) can cause hyponatremia — dilution of sodium in the body. Stick to the body-weight-based formula and listen to your body's signals. Most Kangen users naturally drink more because the water tastes better — and that usually brings them closer to the optimal amount, not above it.
When to drink Kangen water before a meal — how long beforehand?
It's best to drink water 20–30 minutes before a meal. During this time the water is absorbed by the intestines and doesn't dilute gastric juices. Drinking a lot of water right with food — whether Kangen or ordinary — can impair digestion.
Do coffee and tea count toward the daily water intake?
Technically they contain water, but they act as diuretics — they make the kidneys excrete more fluid than was supplied. A cup of coffee (250 ml) causes a loss of about 280–300 ml of water. That's why, when calculating your daily water intake, we count only plain water. Coffee brewed with Kangen water tastes better — less bitter, richer aroma — which for many users is a nice bonus.
What if I forget to drink water on schedule?
Nothing will happen. The schedule is a guide, not a rigid rule. If you forget your morning glass, make up for it during the day. What matters is to consciously pay attention to hydration for the first few weeks — after about a month, drinking water regularly becomes a habit and you no longer need reminders. Many people set a phone alarm at the start.
How much Kangen water to drink during a workout?
Before a workout: drink 0.5 liter of Kangen water at pH 9.5 30 minutes before exercising. During the workout: about 150–200 ml every 15–20 minutes. After the workout: 0.5–0.75 liter within an hour after exertion. Thanks to better cellular absorption, Kangen water rehydrates after a workout faster than ordinary isotonic drinks, while containing no sugar or artificial colorings.
