The Importance of Electrolytes for Fasting
When fasting, your body shifts states from burning carbs to burning fat for fuel - a state known as ketosis hence the popular diet name "Keto".
In this state your body loses electrolytes faster, making you more prone to fatigue and flu-like symptoms.
🤒 Avoid The "Keto Flu"
Whilst fasting, you might feel tired, dizzy, irritable, or have trouble sleeping - even though you’re not actually ill.
That’s because your body switches from burning glucose to fat, lowering insulin levels and prompting your kidneys to flush out sodium and other vital electrolytes.
This drop mimics dehydration and brings on the dreaded “Keto flu.”
Maintaining key electrolytes helps you stay balanced, clear-headed, and energised throughout your fast.
🔋 Stable Energy Levels
It’s super common to feel drained during a fast. What’s happening is your body starts flushing out water and electrolytes - especially sodium once you stop eating.
Since you’re not fuelling your body, you can end up feeling dehydrated and low on energy.
A little electrolyte support can go a long way in helping you feel better and more balanced.
🧠 Support Cognitive Function
Fasting can mess with your mental clarity. When electrolytes drop, you might feel foggy or have trouble concentrating.
Staying hydrated with the right balance of electrolytes helps keep your mind sharp and focused while you fast.
🏃♂️ Enhance Your Exercise
Electrolytes are crucial if you’re exercising while fasting.
Your body already loses electrolytes during a short intermittent fast, and working out speeds up that loss through sweat.
Replenishing with electrolytes helps you stay hydrated, energised, and fights off the fatigue you typically feel after working out.
🦵Prevent Muscle Cramps
Muscle cramps are usually a sign you're low on electrolytes - especially sodium and potassium.
Think of potassium like a superhero for your muscles and nerves. When you don't have enough potassium, it's like the superhero isn't there to help. Your muscles and nerves can't communicate with each other, causing cramps or muscle pains.
Staying hydrated with the perfect electrolyte formula helps keep those superheroes in action - and the cramps away.
⚖️ Balanced Blood Sugar
We all know hunger is part of fasting.
But staying topped up on electrolytes - especially magnesium can help regulate mood, reduce stress, and make those hunger cues easier to manage. That means fewer cravings and an easier fasting experience.
⚡️ Maintain Hydration
Your body doesn’t hold onto electrolytes for long, and during a fast, you use them up even faster. Once those levels drop, you can start feeling the effects - fatigue, headaches, brain fog, muscle cramps, nausea, and a dip in performance. Staying hydrated with the right electrolytes helps keep you feeling your best.
When fasting, your body shifts states from burning carbs to burning fat for fuel—a state known as ketosis.
This change can lead to a drop in key electrolytes, making you feel tired, dizzy, or having flu-like symptoms. Keeping your electrolytes balanced helps you stay sharp and energised while fasting.
The Science-Backed Benefits of Fasting
There's some science behind the hype - even intermittent fasting is linked to lasting health benefits from brain health to weight loss.
🫀
Heart Health
LOWER LDL & TOTAL CHOLESTEROL
A recent study linked alternate day fasting to lower levels of key heart health markers like triglycerides, total cholesterol and the "bad" LDL cholesterol.
🧠
Cognitive Protection
COGNITION BOOSTER
While animals have only been studied thus far for links to brain health, the results have been overwhelmingly positive for cognitive performance.
Fasting can reduce inflammation which may lead to neurodegenerative disorders like Alzheimer's disease and Parkinson's, it may also enhance cognitive function by increasing the generation of nerve cells in the brain.
🔥
Weight Loss
METABOLISM BOOSTER
Not only does fasting limit your total calories consumed, but it also revs your metabolism.
Studies link consistent use of Intermittent Fasting to effective reductions in weight by many dieters.
🍩
Blood Sugar Control
REDUCED INSULIN RESISTANCE
Even doing intermittent fasting just three times a week can help your body transport glucose from your blood to your cells more efficiently, lowering your risk of Type 2 Diabetes.
🧊
Soothe Inflammation
REDUCED LEVELS OF C-REACTIVE PROTEIN
A 2022 study showed that moderate intermittent fasting practices reduced key markers of inflammation like lower levels of C-reactive proteins.

"As a mum that does school runs and works full time this has been a lifesaver for me. I never drink enough water during the day but now I take one of these in the morning and feel so much better now that I know I’m getting my full water intake. I never write reviews, but this is really worth a try."

INGREDIENTS YOU CAN TRUST
Himalayan Salt
Hydrate rapidly
Each of our sachets contains 750mg of sodium that comes from Pink Himalayan Salt which also boasts 80+ trace minerals that are vital for your wellbeing - compared to the nutritionally inferior table salt that other brands use to lower their costs.
Magnesium
Fluid balance
Magnesium helps cells manage water inside them, which means maintaining the right balance of fluids. It also supports the function of ion channels and assists in controlling the movement of electrolytes through specialised channels and pumps in your body.
Potassium
Muscle cramping
Think of potassium like a superhero for your muscles and nerves. When you don't have enough potassium, it's like the superhero isn't there to help. Your muscles and nerves can't communicate with each other, causing cramps or muscle pains. So potassium is vital in helping facilitate those muscle contractions.
Calcium
Strong bones
Calcium acts as a conductor in your body, overseeing muscle function, nerve communication, and heart rhythm. It also contributes to the strength and health of your bones. Maintaining the right calcium levels is essential for your overall health, including strong bones.
Vitamin C
Immune support
We've included Vitamin C because it's crucial for supporting your immune system, promoting liver function, and enhancing your body's natural collagen production for healthier skin and joints.
Himalayan Salt
Each of our sachets contains 750mg of sodium that comes from Pink Himalayan Salt which also boasts 80+ trace minerals that are vital for your wellbeing - compared to the nutritionally inferior table salt that other brands use to lower their costs.

Frequently Asked
Questions
You got questions. We got answers.
How many servings are there in the each tub?
We're not like most brands, we provide you with enough servings to last an entire month. Each tub contains 30 servings :)
Can’t i just drink Lots of water when fasting?
Water alone doesn’t contain enough electrolytes to replenish what you actually lose during the day.
Throughout your fasts, the body loses sodium and potassium. So just drinking tons of water without replacing these can dilute your body’s electrolyte levels, disrupting the balance, which is why most people feel fatigued whilst fasting.
Can I use these during intermittent fasting?
Yes! Most of our customers use Strike during intermittent fasting.
It’s packed with essential electrolytes and 80+ trace minerals to support hydration, energy, and focus - all without breaking your fast. Many people find it helps make longer fasting windows more manageable.
HOW DOES STRIKE DIFFER FROM OTHER ELECTROLYTES?
Most other brands and sports drinks are typically high in sugar, calories, carbohydrates and other additives that would instantly break a water fast.
Strike is made without sugar, artificial sweeteners, or any ingredient that will break your fast.
How will I feel when taking Strike?
Strike is a 'for us, by us' product, meaning we've designed and developed it for ourselves first, knowing that people just like us (athletes, entrepreneurs, & those that don’t have enough time in the day to drink tons of water) will love it too!
The whole idea of Strike centres around hydrating in a faster and more efficient way, meaning you can simply take one sachet every morning and never struggle again to hit your daily water intake. In summary, you will feel hydrated and less fatigued throughout the day, both mentally and physically - zero jitters & zero crash.
How much should I take and when?
We've formulated Strike to be a once per day, 'all in one' electrolyte - super convenient & easy to take. You can however consume 2-3 sachets daily depending on how tired you feel during the fasts or if you exercise a lot.
HOW DO I USE STRIKE?
Simply add 1 sachet to 350-400ml of water and enjoy a refreshing drink in seconds.
Is there any caffeine INSIDE?
Nope, Strike is 100% caffeine-free.
is it vegan and gluten free?
Yes, our electrolytes are 100% vegan and gluten free. They're also non-GMO and paleo-keto friendly.
When can I expect to receive my order?
