FAQ's

During heavy or prolonged sweating, you lose both water and electrolytes, especially sodium. Using excessive hypotonic fluids such as plain water or very low‑electrolyte drinks can dilute blood sodium and may not fully restore how you feel or perform.

Replacing the electrolytes lost helps your body move fluid in and out of cells, maintain blood volume, and support muscle and nerve function, helping reduce the risks of cramps, fatigue and that “still dehydrated” feeling associated with sweat losses.

If you want the science behind this, see: why water alone isn’t enough when you’re sweating.

Sodium is a primary electrolyte lost in sweat and plays a key role in hydration, nerve signalling and muscle function. Potassium helps regulate fluid balance and how sodium is handled in the body, supporting normal physiological function. This is one of the reasons Purelyte is formulated with a 2:1 sodium-to-potassium ratio, reflecting typical sweat losses and how these electrolytes work together.

When sweat loss is meaningful, replacing both is often essential. If you have a medical condition requiring sodium restriction, follow your clinician’s advice.

See this article for an in depth look into the role of sodium in hydration and electrolyte balance.

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 electrolyte losses. By replacing these electrolytes, it allows water to be absorbed and retained more effectively, supporting hydration when sweat loss is meaningful.

For a detailed breakdown of the formulation and how it works, see How Purelyte Works.

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.

See this article to understand more about the relationship between sweat and electrolytes.

Purelyte is designed to be mixed with 600–1200 ml of water, depending on your needs. Most people prefer it around 800–1000 ml. Mixing stronger than 600 ml is generally not recommended, as additional benefits are minimal. Mix stronger within this range when sweat loss is higher, such as during heat, training or physical work, and lighter when sweat loss is lower. Adjust based on conditions and taste preference.

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.

Purelyte can be used before, during or after exercise, depending on the duration, intensity and how much you’re sweating.

For shorter or lighter sessions, many people use it before or after training to support hydration. During longer, hotter or more demanding sessions, sipping Purelyte during exercise can help replace electrolytes as they’re lost through sweat.

For longer or higher-intensity training, hydration and fuelling should be planned together. Purelyte supports electrolyte replacement but does not provide energy. We recommend meeting carbohydrate needs through solid foods or properly formulated fuelling liquids or gels, rather than relying on sugary drinks, to help avoid sharp sugar spikes and energy crashes.

Yes. Daily hydration matters, and Purelyte is designed to support regular use. Many people use it consistently while fasting, training, working long shifts or to support day-to-day focus and hydration. For general hydration, up to 2 sachets per day is typically sufficient, unless sweat loss is higher or dietary needs differ. If you have specific medical conditions or concerns, consult your healthcare professional.

Purelyte contains no sugar, no hidden carbohydrates such as maltodextrin, and no fillers. It is commonly used during fasting, ketogenic and low-carbohydrate approaches where electrolyte loss can increase. Many people use it to support hydration without disrupting their routine.

See this article for a look into
the role of electrolytes during fasting and low-carbohydrate diets.

Over 80% of Australians are dehydrated daily because it
isn’t just about how much water you drink—it’s about whether your body can retain and use that fluid effectively.

Spot dehydration through telltale signs like:

• intense thirst or dry mouth
• headache or fatigue
• brain fog or poor concentration
• dizziness when standing
• muscle cramps or twitching
• rapid heartbeat

These symptoms can occur even if urine looks pale, especially after drinking plain water.

Why urine colour isn’t foolproof

Dark yellow urine usually indicates dehydration.

However, pale urine can sometimes reflect dilution rather than proper hydration, particularly if electrolytes are low. Without enough sodium and supporting minerals, water is more likely to be excreted than retained in cells.

More reliable clues

• Persistent thirst or dryness
• Reduced performance, cramping, or fatigue despite drinking fluids
• Mental fog or poor recovery
  

These often point to electrolyte imbalance, not just low fluid intake.

What helps

Rehydrating with fluids that contain sodium, potassium, magnesium, and calcium supports fluid retention, nerve signalling, and muscle function—helping restore hydration at a cellular level, not just in the stomach or bladder.

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.

No — Purelyte is 100% natural. It contains no artificial colours, flavours, preservatives or sweeteners.

For Purelyte, clean ingredients means a short, purposeful formula with only 8 ingredients, and no artificial colours, flavours, preservatives or artificial sweeteners, and no fillers or hidden carbohydrates such as maltodextrin.

Purelyte is built around replacing the key electrolytes lost in sweat. The remaining ingredients are included for specific reasons: citric acid helps maintain a stable, slightly acidic pH for product quality and palatability, while fruit powder, natural flavour and stevia provide a clean taste without adding sugar.

Each ingredient has a defined function and is selected for bioavailability, absorption, gut tolerance and overall quality, rather than unnecessary additives.

Yes. Purelyte is manufactured in a facility that operates under GMP (Good Manufacturing Practice) and HACCP food safety systems, which are internationally recognised standards for quality control, traceability and risk management.

Each production batch is also tested for microbiological safety and heavy metals to ensure it meets strict quality and safety specifications before release.

This layered approach helps ensure Purelyte is consistently produced, safe to use and suitable for regular hydration.

Yes. Selected Purelyte flavours — Lemon Lime and Raspberry — have been batch tested by Australia’s largest independent sports drug testing laboratory.

The testing screens for over 250 substances on the World Anti-Doping Agency (WADA) Prohibited List. Batch test results are available upon request.

Purelyte is also manufactured in an NSF-certified facility, which operates under strict quality and manufacturing controls designed to reduce the risk of cross-contamination with banned or undeclared substances.

As with all supplements, athletes competing under anti-doping rules remain responsible for what they consume. We recommend elite or tested athletes confirm suitability with their sporting body or support team.

For most people, supporting proper hydration helps reduce the risk of kidney stones, as dehydration is one of the strongest contributors to stone formation.

Purelyte is formulated using citrate-based mineral forms, including potassium citrate and calcium citrate, along with magnesium. Citrate is widely recognised for its role in supporting a more favourable urinary environment, while magnesium and calcium can help limit oxalate binding when consumed as part of normal hydration.

When used as directed and mixed with 600–1200 ml of water, Purelyte supports hydration and dilution, which are key factors in kidney stone risk management. If you’re concerned about kidney stones and have no history of kidney disease, mixing Purelyte with 800 ml or more of water can further support urine dilution as part of overall daily fluid intake.

This approach can be more supportive of hydration balance than plain water alone or high-sodium drinks, which may not replace electrolytes effectively or may increase concentration without adequate dilution.

Purelyte is designed for hydration support, not medical treatment. If you have a history of kidney stones or a diagnosed kidney condition, individual medical advice should always take priority.

Purelyte has a shelf life of 24 months from the date of manufacture.

It is produced in a humidity-controlled manufacturing facility and packaged using moisture-protective materials to help maintain product stability, quality and effectiveness over time.

Each pack is clearly marked with a best before date, and when stored in a cool, dry place away from heat and moisture, Purelyte will remain stable and effective until that date.

Because Purelyte contains no sugar and no perishable ingredients, it is well suited to regular use and longer-term storage.

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.

We explain this in more detail here: Hydration for Active Kids: What Parents Need to Know About Sweat, Electrolytes & Sugary Drinks

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.

Yes. Chloride is an electrolyte and plays a role in fluid balance and electrical neutrality in the body. It is also a component of stomach acid involved in digestion.

In hydration, chloride is almost always lost and replaced alongside sodium, most commonly as sodium chloride. Because isolated chloride deficiency is extremely rare, hydration strategies focus on sodium as the primary driver of fluid balance, with potassium, magnesium and calcium supporting muscle and nerve function.

Phosphorus, present in the body as phosphate, is an electrolyte involved in energy production and normal cellular function. Unlike sodium or potassium, it does not play a primary role in fluid balance or hydration.

Phosphate deficiency is rare, in part because most Western diets already provide ample — and often more than sufficient — phosphate from common foods. It is also not typically related to sweating.

For this reason, hydration strategies focus on electrolytes that meaningfully affect fluid balance and muscle function, such as sodium, potassium, magnesium and calcium.

Purelyte is designed to help reduce the risk of cramps and fatigue by replacing the electrolytes your body needs to support normal muscle function and energy production.

It works best when used before and during periods of heavy sweating, rather than as a treatment once cramps have already started.

👉 For a deeper explanation, see Electrolytes for cramping and muscle fatigue.

If a cramp has already started, fast relief is sometimes achieved with very strong salty or acidic solutions (such as pickle juice), which can trigger a rapid neural reflex in the mouth and throat. This works too quickly to be explained by electrolyte absorption.

If those aren’t available, some people use Purelyte at a stronger concentration than usual. While this is unlikely to act as quickly as pickle juice, it can provide milder sensory input and has the added benefit of beginning electrolyte replacement to help reduce the chance of the cramp returning.

Purelyte is formulated to replace the electrolytes lost in sweat, rather than being optimised for sweetness or flavour. If you’re used to plain water, sugary drinks or lightly dosed electrolytes, it may initially taste quite salty. This is common with higher-electrolyte formulas. With consistent use over a few days, taste perception often adjusts. Many people also find it tastes more balanced when used during or after meaningful sweat loss, when electrolyte needs are higher.

Purelyte includes higher levels of potassium (400 mg), magnesium (100 mg), and calcium (100 mg) per serving than typical sweat losses to address common deficiencies in the Western diet, where average intakes fall short of recommendations—such as ~2,600 mg potassium versus 4,700 mg needed daily—due to low fruit, vegetable, and whole food consumption.

This formulation adheres to an optimal 2:1 sodium-to-potassium ratio (800 mg sodium: 400 mg potassium), restores membrane potential and better supports nerve function, muscle contraction, fluid balance, and cardiovascular health during activity compared to more sodium-dominant alternatives. These elevated minerals enhance cellular hydration, reduce cramping risks, and promote faster recovery for athletes and active individuals beyond mere sweat replenishment.

Many people notice a difference within 30–60 minutes during or after periods of heavy sweating, exercise or heat exposure.

For everyday hydration or fasting, the effects are usually more gradual. Most people notice clearer benefits after around 5 days of consistent use, as electrolyte balance is maintained more reliably over time. Rather than feeling “boosted,” people often describe the experience as feeling steadier, calmer and more regulated — with fewer headaches, hunger cues or energy fluctuations.

Interestingly, one of the clearest signals for many users is when they stop using Purelyte after a period of regular use. Feelings like fatigue, cramping, brain fog or false hunger can return, highlighting how much electrolytes were quietly supporting hydration in the background.

Purelyte isn’t designed to stimulate or optimise performance. It’s designed to replace the electrolytes you lose in sweat — helping hydration feel uneventful, stable and easy to maintain.

Yes. Serious athletes don’t benefit from pushing sodium concentration as high as possible. Most performance hydration occurs within a functional range of ~40–60 mmol/L sodium (roughly one serve of Purelyte in 600–900 mL of water), where fluid retention is maximised and higher concentrations offer diminishing returns.

Purelyte can be mixed more concentrated for short, high-intensity or time-compressed sessions, or diluted over more water for longer or steadier efforts. In practice, performance outcomes are driven more by timing, total intake, and individual sweat rate than by pushing electrolyte concentration higher.

Purelyte is designed to support hydration during long or high-sweat sessions by replacing the electrolytes you lose in sweat. When electrolyte levels drop, issues like cramping, early fatigue or loss of focus can appear, even if you’re drinking plenty of water.

By restoring key electrolytes, Purelyte helps maintain fluid balance and normal muscle and nerve function, which can support consistency and comfort during prolonged or demanding activity.

For high-level or endurance athletes, hydration is only one part of performance. A structured fuelling plan — including appropriate energy and carbohydrate intake — is also important. Purelyte is intentionally formulated without carbohydrates, so electrolyte replacement isn’t compromised or diluted by added fuel. This allows athletes to manage hydration and fuelling separately, based on their specific needs.

Purelyte doesn’t act as a stimulant or energy booster. Its role is to ensure hydration keeps pace with sweat loss, so performance isn’t limited by avoidable electrolyte depletion.

At the moment, we don’t offer individual sample sachet packs.

Purelyte is formulated for real sweat loss, so most people need more than a single serve to properly feel the difference. That’s why we recommend starting with a multi-sachet pack so you can use it across training, work or hot days and see how your body responds.
