Electrolytes are essential minerals that regulate fluid balance, nerve function and muscle performance. You lose them through sweat — and most drinks don’t fully replace them.

Purelyte helps restore what your body actually needs to perform, think and recover — without sugar, fillers or artificial additives.

Purelyte contains the four key electrolytes lost in sweat — sodium, potassium, magnesium and calcium — in levels that meet or exceed average sweat loss. It dissolves fast and absorbs efficiently to support hydration, endurance, recovery and mental clarity.

For more information see How Purelyte Works.

Yes, Purelyte helps prevent cramps and reduce fatigue by replenishing key intracellular minerals—potassium (400 mg), magnesium (100 mg), and calcium (100 mg)—that support muscle contraction/relaxation, nerve signaling, and energy production, often depleted beyond sweat losses due to dietary gaps and exercise demands.

Yes — Purelyte contains zero sugar, zero carbs and no artificial sweeteners. It’s ideal for intermittent fasting, low-carb diets and clean eating.

Purelyte is formulated to match or exceed the average electrolyte losses found in 1 litre of human sweat — based on clinical research across athletes, workers, and active individuals.

Here’s how it stacks up per serve:

Most people lose on average approximately:

• ~800mg of sodium
  
• ~250mg of potassium
  
• ~36mg of magnesium
  
• ~20mg of calcium
  

Each serve of Purelyte contains:

• 800mg sodium (from Pink Himalayan Salt)
  
• 400mg potassium
  
• 100mg magnesium
  
• 100mg calcium

While individual sweat profiles vary, Purelyte is designed to fully replace — or slightly exceed — what most people lose. That means better hydration, fewer cramps, faster recovery, and improved clarity.

Unlike most products that are underdosed or sugar-loaded, Purelyte gives you just what your body needs — and nothing it doesn’t.

Use Purelyte anytime you’re losing fluids, under-hydrated, or need sustained mental and physical performance.

Common times to use Purelyte

• First thing in the morning – you wake up mildly dehydrated after overnight fluid loss
• Before, during, and after exercise – to support hydration, endurance, and recovery
• During fasting or keto – helps prevent electrolyte depletion and fatigue
• Long work shifts or hot outdoor days – replaces fluids and minerals lost through sweat
• When feeling fatigued, foggy, or cramp-prone – common signs of electrolyte imbalance
  

Simple rule of thumb

If you’re sweating, mentally demanding more from your body, or drinking lots of plain water, electrolytes help you stay hydrated at a cellular level.

Yes — and we actually encourage it.

Daily hydration matters and Purelyte is designed to support it. Whether you're fasting, training, working long shifts or just trying to stay sharp, consistent electrolyte support can help prevent cramping, fatigue, and brain fog.

For general hydration, we recommend up to 2 sachets per day unless you’re sweating heavily or have specific dietary needs. If in doubt, consult your healthcare professional.

No — Purelyte contains no maltodextrin, sugar or hidden carbs.

It’s 100% keto-friendly and formulated with clean, natural ingredients only. Many keto and low-carb customers use Purelyte to stay hydrated and prevent cramps without breaking ketosis.

Yes — Purelyte is classified as a Formulated Supplementary Sports Food and carries the standard advisory that it’s not recommended for children under 15 or pregnant women unless under medical or dietetic supervision.

That said, many parents choose to use Purelyte as a clean, sugar-free hydration option for kids during sports or recovery. If you're unsure, we recommend consulting your healthcare professional.

Yes, Purelyte can be safely used during pregnancy by many women for enhanced hydration, energy support, and cramp relief, thanks to its clean, sugar-free formula with balanced electrolytes (800 mg sodium, 400 mg potassium, 100 mg magnesium/calcium).

As a Formulated Supplementary Sports Food under Australian regulations, it carries the standard advisory to consult a healthcare professional before use, especially if you have specific health conditions. Pregnancy increases electrolyte demands due to higher fluid needs, blood volume expansion, and potential losses from nausea or activity, making Purelyte a preferred alternative to sugary drinks.

Key Benefits

• Supports fluid balance and nutrient transport without artificial additives or excess sugar.
• Aids in preventing dehydration-related issues like fatigue or preterm contractions.

If you're pregnant or breastfeeding, we recommend speaking with your healthcare professional for advice. They may suggest dosage adjustments based on trimester or needs.

Yes, Purelyte is suitable for breastfeeding mothers to maintain hydration and replenish electrolytes lost through increased fluid production (up to 800 mL milk daily), sweat, or activity, with its clean, zero-sugar profile providing sodium (800 mg), potassium (400 mg), magnesium (100 mg), and calcium (100 mg) without passing stimulants or additives to breast milk.

As a Formulated Supplementary Sports Food, follow the label advisory to consult a healthcare professional, particularly if managing conditions like gestational diabetes or sodium sensitivity. Breastfeeding elevates mineral needs (e.g., +300 mg calcium, +500 mg potassium daily), and Purelyte helps meet them effectively over plain water or sugary alternatives.

Key Benefits

• Supports milk supply via optimal hydration and combats fatigue/cramps from postpartum recovery.
• Maintains electrolyte balance for energy without risking infant exposure to caffeine or sugars.​

Seek advice from your doctor, lactation consultant, or midwife for tailored use, especially in early weeks or with high activity levels.
