Functional Wellness During Ramadan: Hydrate to Elevate

Ramadan is no longer just about getting through the day, but performing through it. Across the UAE and wider region, fasting is being reimagined through a functional wellness lens, with consumers paying closer attention to hydration quality, electrolyte balance and nutrient timing between Suhoor and Iftar.

For Arsh Mehta, Founder of Cancro, this shift marks a defining moment. As fatigue and brain fog become common fasting complaints, many are realising that simply drinking more water isn’t enough, what matters is how effectively the body can use it. From deuterium-depleted water to performance-driven supplementation designed specifically for compressed intake windows, Ramadan is fast becoming a proving ground for smarter hydration and sustained energy strategies.

In this exclusive interview, Arsh explains why the Holy Month is reshaping consumer habits, how science-backed hydration can support clarity and stamina, and why Ramadan may become the region’s most important season for functional wellness brands.

We’re seeing a rise in functional wellness during Ramadan. How have consumer habits evolved when it comes to supplements and performance-focused products while fasting?

Ramadan used to be about getting through the day. Now people want to perform through it. Consumers started asking better questions. Not just “what should I eat at Iftar?” but “how do I stay sharp at 3 PM while fasting?” That’s a different mindset. Functional beverages have become part of how serious fasters plan their Suhoor and Iftar. People treat their hydration and nutrition windows with the same discipline they bring to their spiritual practice.

Fatigue and brain fog are common complaints during fasting. How can smarter electrolyte balance and nutrient replenishment support sustained energy and mental clarity throughout the day?

Most fatigue during fasting isn’t from lack of food. It’s from the quality of what people consume in their two intake windows. Your body has a narrow window to prepare for 14-plus hours without any intake. What you put in during Suhoor and Iftar determines how you feel at 3 PM.

This is where water quality matters more than people realize. Not all water is the same. Deuterium-depleted water reduces the load of heavy hydrogen your cells have to process. When your body spends less energy on basic cellular function, there’s more left for you to use through the day.

Many people think simply “drinking more water” is enough. Can you explain the science behind electrolyte balance and why it matters just as much as fluid intake?

Volume alone doesn’t solve hydration. Your body’s ability to use the water you drink matters just as much as how much you drink. Most people don’t think about what’s in their water beyond whether it’s clean. But water varies at the molecular level.

Deuterium is a heavier form of hydrogen that occurs naturally in all water. At high concentrations, it makes cellular processes work harder. Reducing deuterium levels means your body can do more with less. During fasting, when you can’t course-correct through the day, starting with better water is one of the simplest upgrades you can make.

How are performance-driven supplements being adapted specifically for fasting individuals, and what makes Ramadan wellness different from regular wellness routines?

Regular wellness routines assume constant access. You can snack, hydrate, and supplement whenever you want. Ramadan removes that. Products designed for fasting need to work within compressed intake windows and sustain their effect across long gaps.

At Cancro, we start with deuterium-depleted water at 125 PPM, well below the 150 PPM found in regular water. We then add functional ingredients like curcumin and iodine that complement fasting rather than fight against it. The thinking is simple. Give the body cleaner inputs during the only windows it has to receive them.

Ramadan is also a high-consumption retail period. How important is it for wellness brands to be available both in trusted supermarkets and through seamless online platforms?

Ramadan compresses decision-making. People stock up fast, and they buy from wherever is most convenient and most trusted. We made sure Cancro is available where those decisions happen. Online, you can find us on our website, Amazon, and Noon. In stores, we’re on shelves at Al Maya supermarkets across the UAE.

For a product where education is part of the purchase, our online channels give us space to explain the science. Al Maya gives us the physical credibility and grab-and-go access that matters during a month when people are shopping between Iftar and Taraweeh.

Do you see Ramadan becoming a defining moment for functional wellness brands in the region in the future? How is Cancro positioning itself at the centre of this growing fasting-health conversation?

Millions of people simultaneously change how they eat, drink, sleep, and move for an entire month. No other cultural moment creates that kind of unified behavior shift. For functional wellness brands, it’s a chance to prove relevance under real constraints.

Cancro is positioning around a simple idea. The water you break your fast with should be the best water available. We’re not trying to own the entire fasting-health conversation. We want to own the hydration piece of it, with science that holds up and a product people reach for because they feel the difference.
