Alkaline water benefits: what 96.9% of tasters already know.
The alkaline water benefits people actually notice: calcium, magnesium and potassium in every glass, molecular hydrogen infused at bottling, and a taste 96.9% preferred in an independent taste test of 390 non-customer respondents. pH 10, bottled at source in South Africa.

The difference
Alkaline water benefits go further than most people expect.
From better hydration and mineral intake to a smoother taste that 96.9% preferred in an independent taste test of 390 non-customer respondents.
Alkaline water at pH 10 delivers calcium, magnesium and potassium in every glass, plus molecular hydrogen and reduced ORP at time of bottling. It's not magic. It's mineralised water that tastes better and gets more of it down you.

What's inside
Your alkalinity comes from real minerals.
Much bottled water is filtered tap water with a label. Ours is different. The alkalinity comes from dissolved minerals your body uses every day.
Ca
Calcium
Bones and teeth
Essential for bone density, muscle function and nerve signalling. Designer Water adds calcium during the mineralisation stage of bottling.
Mg
Magnesium
Energy and recovery
Involved in over 300 enzymatic reactions including muscle and nerve function. Magnesium-rich water is one of the simplest ways to top up.
K
Potassium
Hydration and balance
Helps maintain fluid balance and supports nerve and muscle function, especially during exercise and hot weather.
H₂
Molecular hydrogen and reduced ORP
Every bottle is infused with molecular hydrogen and has a reduced Oxidation-Reduction Potential at time of bottling. These are factual descriptions of how the water leaves the line, not health claims.
The pH scale
What pH level is alkaline water?
The pH scale runs from 0 (most acidic) to 14 (most alkaline), with 7 being neutral. Every whole number is a tenfold change. Water at pH 10 is 1 000 times more alkaline than pH 7.

Designer Water
Premium alkaline.
Your body keeps blood pH within a tight range of 7.35 to 7.45 through its own buffering systems. Drinking alkaline water does not change your blood pH. What it provides is a source of essential minerals in every glass.
What the research says
Alkaline water benefits. Peer reviewed.
We don't make health claims. We point you to published research and let you decide. Both the alkaline water benefits and risks are covered honestly on this page.
Hydration
Improved hydration markers
A 2016 study in the Journal of the International Society of Sports Nutrition found that high-pH alkaline water improved hydration markers compared to standard purified water following exercise-induced dehydration.
J Int Soc Sports Nutr · 2016
Minerals
Calcium and magnesium intake
The World Health Organization has noted that drinking water can be a meaningful source of calcium and magnesium. Alkaline water that gets its pH from added minerals contributes to daily intake.
WHO · Drinking-water Guidelines
Habits
Smoother taste, more litres
Higher mineral content and a higher pH give a smoother taste. When water tastes better, people drink more of it. That alone is worth paying attention to.

Exercise
Hydration after exercise
A study in Biology of Sport compared hydration status after exercise with different waters. We link to it rather than draw conclusions from it. Drink enough water around training, whatever water you choose.

Hydrogen
Molecular hydrogen water
Hydrogen water benefits are an emerging area of research. Designer Water is infused with molecular hydrogen at time of bottling. Molecular hydrogen (H₂) is the smallest molecule and is added during our production process.

Acid reflux
Pepsin denaturation (Koufman 2012)
Research published in The Annals of Otology, Rhinology & Laryngology found that water with a pH of 8.8 irreversibly denatured human pepsin in laboratory conditions and buffered acid effectively.

Acid reflux
Alkaline water for acid reflux: the Koufman study.
The paper people ask us about most. Here is what it measured, and what it did not.
Key study · 2012
Koufman & Johnston (2012)
Research published in The Annals of Otology, Rhinology & Laryngology found that water with a pH of 8.8 irreversibly denatured human pepsin in laboratory conditions and buffered acid effectively. It was a laboratory study, not a clinical trial. We describe it as research, not as a benefit.
Important: alkaline water is not a medicine and is not a substitute for medical care, for acid reflux or anything else. If you have ongoing reflux symptoms, see a healthcare professional. Individual results may vary. Not medical advice.

"I have to say I was a bit skeptical when my mother told me about this water. So I bought it and the whole family don't want tap water anymore and even my daughter who didn't like drinking water, is drinking this water and calls it tasty water!!!!"

"So, since moving off the farm where we had water supplied by a natural spring. I have been un-able to drink the amount of water (tap or bottled) that I require. Then I found this stuff! Tastes like the farm. Highly Recommended!"

Honest balance
Alkaline water side effects and risks.
A balanced view of the alkaline water benefits and risks. Here's what you should know.
01
It won't change your blood pH
Your body handles that on its own. What alkaline water provides is a source of essential minerals in every glass.
02
Not all alkaline water is equal
Some brands artificially raise pH without adding minerals. Designer Water's alkalinity comes from a natural remineralisation process. Look for SANBWA certified.
03
Check with your doctor
If you have kidney disease or take medication that affects electrolyte balance, speak to a healthcare professional first.
04
The research is promising but early
We present what exists honestly and don't overstate it.
05
Hydration is the priority
The most important thing is that you drink enough water, 2 to 3 litres a day. If you're going to drink that much, it might as well taste incredible and carry minerals you actually need.
06
Designer Water's approach
SANBWA certified, ISO 22000, mineralised at source, molecular hydrogen infused. We don't ask you to take our word for it. We point you at the certifications.
FAQ
Alkaline water. Your questions, answered.
Eight of the most asked alkaline water questions, answered straight.
How much alkaline water can I drink a day?
As much as you'd normally drink. 2 to 3 litres is the general recommendation. If you have kidney conditions or take medication that affects pH balance, check with your doctor first. Read our full guide.
What are the side effects of alkaline water?
For most people, none. Some notice mild digestive adjustment in the first few days. If you have kidney disease, consult your doctor. Read about side effects in detail.
What is the pH of Designer Water?
pH 10. The alkalinity comes from added calcium, magnesium and potassium, and every batch is tested for consistency.
Is alkaline water good for you?
Alkaline water provides essential minerals like calcium, magnesium and potassium in every glass. One 2016 study reported improved hydration markers with high-pH water after exercise. It's not a medicine, but it's a meaningful upgrade on plain bottled water.
Is alkaline water better than regular water?
Both hydrate you. The difference is mineral content and taste. A 2016 study showed improved hydration markers with high-pH water, and 96.9% preferred Designer Water in an independent taste test of 390 non-customer respondents.
Does alkaline water help with acid reflux?
Research by Koufman & Johnston (2012) found that water at pH 8.8 denatured pepsin in laboratory conditions and buffered acid effectively. It was a laboratory study, not a clinical trial, and it is research rather than a promise. Alkaline water is not a substitute for medical care.
