The smart solution for hydration

01

An essential pick me up

Picture a San Pellegrino but for those who need to get more done. We’ve added caffeine, natural flavourings and all the essential electrolytes you need to feel rejuvenated, revitalised, and focused for the ‘Big Day’ ahead. 

02

No more “feeling flat”

You need to replenish what you lose in a day. Our formula helps you do exactly that. The perfect hack for restoring that crucial vitality you lose throughout the day.

03

More hydrating than “just” water

Chances are you’re not properly hydrating yourself and you don’t even know it. That mid-afternoon slump you feel? General fatigue? Slow recovery? Simply moving away from drinking as much water as possible and instead consuming the right minerals and electrolytes your body needs can dramatically improve your daily performance.

04

Convenient hydration 

The fact is you hydrate faster and more effectively with Big Day than water alone. Not just because of our formula, but because of how easy it is to now consume the electrolytes and minerals needed to boost your performance.

6 electrolytes

01. Potassium

02. Sodium

03. Chloride

04. Magnesium

05. Calcium

06. Phosphate

01. Potassium

Potassium provides a wide range of key electrolyte benefits that are essential for regulating fluid balance and preserving optimum bodily function. Potassium is a crucial mineral that contributes to normal muscle function, normal functioning of the nervous system and maintenance of regular blood pressure. Its fundamental impact on fluid balance aids in preventing dehydration.

02. Sodium

Sodium plays a crucial part in maintaining the basic physiological processes that support general human health. One of its key roles is fluid balance regulation, which controls how fluids are distributed between the internal and external cell membranes.

03. Chloride

One of the most prevalent electrolytes in the body, chloride is second only to sodium. It plays a key role in the regulation of body fluids.

04. Magnesium

Magnesium is crucial for a number of functions in the body. It contributes to electrolyte balance, reduction of tiredness and fatigue, normal functioning of the nervous system, normal energy-yielding metabolism and normal muscle function.

05. Calcium

Calcium is an essential mineral, especially for skeletal health. It is essential for the maintenance of healthy bones and teeth. It also contributes to normal muscle function, energy-yielding metabolism, blood clotting and neurotransmission.

06. Phosphate

Phosphate is vital for both everyday functioning and during exercise. It is an essential part of adenosine triphosphate, which serves as the main source of energy for cells. Phosphate aids in the creation of DNA, and in energy metabolism, among other fundamental biological processes.

Frequently Asked Questions

Why do I need electrolytes?

When you sweat, you lose more than just water. You lose a ton of electrolytes that are crucial for performing at your best. Replenishing these electrolytes you lose through training can be the difference between feeling on top of your game versus feeling like trash.

Just drink more water, no?

The water we drink doesn’t contain enough electrolytes to replenish what you lose if you train hard and often. You’ve probably felt it yourself. Having hit your water targets for the day, thinking you’ve aced your hydration goals, but you still feel kinda ‘flat’. Restoring your electrolyte balance helps to combat that.

What’s the difference between sachets and cans?

Big Day cans have a modest amount of electrolytes designed to be a great daily amount of electrolyte replenishment. As well as this, the cans have 80mg of caffeine to ensure you are feeling alert and ready to take on the day. The sachets have a generous amount of electrolytes, designed to replenish after particularly strenuous activity.

How much can I take per day?

Sachets : You can safely consume up to 1 sachet per day. You should always start dosage low and increase incrementally based on your individual body’s response. To take, dissolve 1 sachet in 500mL of water during or after your workout. Alternatively take as a pick me up in between meal times. Use cold water for the best flavour result.

Cans : You can safely consume up to 3 cans per day depending on the individual's constitution. You should always start dosage low and increase incrementally based on your individual body’s response.

Pre-Workout : We recommend you don't drink more than 2 cans per day. You should always start dosage low and increase incrementally based on your individual body’s response.
