Premium alkaline water at pH 10, infused with molecular hydrogen, rich in calcium, magnesium and potassium. Bottled at source in South Africa. Official Hydration Partner of PFL Africa.
From better hydration and mineral intake to a smoother taste that 96.9% of people preferred in a taste challenge.
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.
In a taste challenge with 574 South African participants, 96.9% preferred Designer Water over leading brands. Smoother. Cleaner. Once you've had it, everything else tastes flat.

Most bottled water is filtered tap with a label. Designer Water is different — our alkalinity comes from dissolved minerals your body uses every day.
Essential for bone density, muscle function and nerve signalling. Designer Water adds calcium during the mineralisation stage of bottling.
Involved in over 300 enzymatic reactions including muscle and nerve function. Magnesium-rich water is one of the simplest ways to top up.
Helps maintain fluid balance and supports nerve and muscle function — especially during exercise and hot weather.
Every bottle is infused with molecular hydrogen and has a reduced Oxidation-Reduction Potential at time of bottling. Factual process descriptors of how the water leaves the line.
The pH scale runs from 0 (most acidic) to 14 (most alkaline), with 7 being neutral. Every whole number represents a tenfold change. Water at pH 10 is 1,000 times more alkaline than pH 7.

Your body maintains 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.
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.
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.

The World Health Organization has noted that drinking water can be a meaningful source of calcium and magnesium. Alkaline water that derives its pH from added minerals contributes to daily intake.
WHO · Drinking-water Guidelines
Higher mineral content and elevated pH contribute to a smoother taste. When water tastes better, people drink more of it. That alone is worth paying attention to.

Research suggests alkaline mineral water may support faster rehydration after intense exercise, with one study finding reduced cardiovascular strain during recovery.

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.

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.

The most consistently reported benefit from our customers — backed by the only peer-reviewed paper that addresses pepsin and pH directly.

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. This suggests a potential complementary role alongside conventional reflux care.
This water helped me with my acid reflux and heartburn. I would always take an antacid but there was a time when it wouldn't work so I started drinking this water and I've never looked back.

This water has genuinely changed my life. I have gastro-oesophageal reflux disease and despite medication, I experience constant burning. I began drinking alkaline water a week ago…

My family love this brand and the water is the best. Once you use this brand, you'll never drink any other brand.
Manoko · Takealot review
The pH 9.5+ balance makes it feel smoother and more hydrating than regular bottled water. I've noticed I stay energized longer and feel less bloated.

A balanced view of the alkaline water benefits and risks. Here's what you should know.
Your body handles that on its own. What alkaline water provides is a source of essential minerals in every glass.
Some brands artificially raise pH without adding minerals. Designer Water's alkalinity comes from a natural remineralisation process. Look for SANBWA-certified.
If you have kidney disease or take medications that affect electrolyte balance, speak to a healthcare professional first.
We present what exists honestly and don't overstate it.
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.
