The Wellness Report #4: Electrolytes: Functional Fix or Fancy Water?

Why Everyone’s Talking About Electrolytes

Once reserved for elite athletes, electrolytes are now being dropped into water bottles across offices, wellness retreats, and TikTok skincare routines. You’ll find them infused into sachets, smoothies, and sparkling drinks claiming to support energy, focus, skin clarity, and even hormonal balance.

Behind the trend is explosive growth: the global functional water market hit $50.3 billion in 2022, with projections reaching $112.6 billion by 2030. But with claims escalating fast, it raises the question: What exactly are electrolytes and who actually needs them?

What are electrolytes? 

Electrolytes are electrically charged minerals including sodium, potassium, magnesium, calcium, and chloride that control the body’s most essential functions:

•    Regulating fluid balance
•    Facilitating nerve impulses
•    Enabling muscle contractions (including the heart)
•    Maintaining acid-base (pH) balance
•    Supporting cellular hydration

Here’s the key: water alone doesn’t hydrate your cells. For water to be properly absorbed and retained in your tissues, your body requires a balance of electrolytes to transport it across cell membranes via osmosis.

Benefits of electrolytes, backed by science 

1. Energy & Physical Recovery

Hydration affects everything from circulation to temperature regulation to blood pressure stability. Yet research shows that even light sweating, hot environments, or stress can cause significant mineral loss particularly sodium and potassium.

For reference: during moderate activity, you can lose 0.5 to 2.0 litres of sweat per hour, each containing up to 1g sodium/litre. When these aren't replenished, symptoms like fatigue, muscle cramps, dizziness, and poor thermoregulation set in.

Electrolytes (especially sodium and magnesium) slow the rate of fluid loss through urination, allowing water to stay in your bloodstream longer. This is why electrolyte hydration is increasingly used in recovery from heat exhaustion, hangovers, menstrual water retention, and illness-related dehydration.

2. Cognition, Mood & Focus

Even mild dehydration, just a 1–2% loss in body weight via fluid, can impair cognitive performance:

•    Short-term memory
•    Visual-motor tracking
•    Reaction times
•    Mood and alertness

A study published in The American Journal of Clinical Nutrition found that young women with mild dehydration experienced increased fatigue, confusion, and headaches, even without physical activity.

This isn’t just about water, neuronal signalling relies on sodium, potassium, and calcium ion gradients. Without them, brain cells can’t communicate properly, impacting attention, memory formation, and emotional regulation.

That’s why some electrolyte blends now include magnesium and B-vitamins to support the brain’s energy metabolism directly.

3. Immunity & Inflammation

Cellular hydration is vital for the immune response. Electrolytes help maintain fluid distribution between cells and blood vessels, which supports the transport of nutrients, the removal of waste, and the activation of inflammatory pathways when needed.
A poorly hydrated body may have sluggish lymph flow, impaired mucosal barrier protection, and increased oxidative stress all of which increase susceptibility to infection. 
Innovative formulations now include electrolytes with vitamin C, zinc, and adaptogens, aiming to support immune resilience and buffer the effects of low-grade, chronic inflammation, a common driver of fatigue and skin issues.

What most brands don’t tell you: 

You might not need extra electrolytes every day: If you eat a varied diet, don’t sweat excessively, and aren’t chronically stressed, you’re likely getting enough from food:

•    Potassium: leafy greens, bananas, beans
•    Magnesium: nuts, seeds, whole grains
•    Calcium: fortified plant milk, tofu, almonds

For these individuals, electrolyte supplements may be unnecessary or even counterproductive, especially those high in sodium.

Over-supplementing isn’t harmless: Too much sodium from daily hydration powders can lead to bloating, high blood pressure, and in extreme cases, kidney strain. Excess magnesium, while usually excreted, can cause diarrhea and nausea.

And many commercial drinks and powders overpromise with trace mineral doses, but underdeliver on actual electrolyte content - often loaded with sugars, artificial colours, caffeine, and gums instead.

Our Take

Hydration isn’t about drinking more, it’s about absorbing better. And that means supporting your cells with what they need. That’s why we launched Nutriburst Hydration: a science-backed formulation designed for real daily demands, not marketing gimmicks.

✔️ Low in sodium, so it supports balance without overload
✔️ Rich in potassium and magnesium, for true cellular hydration
✔️ Fortified with key vitamins for energy, focus, and immunity
✔️ Free from sugar, artificial colours, and unnecessary fillers

Because whether you’re on your period, in a heatwave, hungover, or just tired of feeling off, your hydration should actually do something.
