“Many of my clients come in with a cluster of symptoms – poor sleep, anxiety, cramps – and we find magnesium is often the key piece of the puzzle.”

What is inside
Key Ingredients & Benefits
No filler, no guesswork. Every ingredient earns its place in the chew, chosen for what it does, not how it sounds.
Vitamin B6 & Vitamin B12
These essential B vitamins help your body unlock energy from food by converting carbohydrates, proteins, and fats into usable energy.
Benefits include:
- Supporting normal energy-yielding metabolism.
- Helping reduce tiredness and fatigue.
- Supporting red blood cell production.
- Contributing to normal psychological function.
Facts about Vitamin B12
Around 6% of adults under 60 and 20% of adults over 60 are deficient in Vitamin B12.
Extreme fatigue and shortness of breath are common signs of deficiency.
Research suggests that among individuals with Vitamin B12 deficiency:
- 96% experience fatigue.
- 87% report waking up tired.
Facts about Vitamin B6
Approximately 12–15% of men and women fail to meet recommended daily intake levels.
Vitamin B6 deficiency may contribute to anaemia, which can cause persistent tiredness and fatigue.
Vitamin C
Vitamin C:
- Supports normal immune function.
- Improves iron absorption.
- Acts as a powerful antioxidant, helping protect cells from oxidative stress.
Sodium, Potassium & Magnesium
Electrolytes work together as foundational pillars for your wellbeing. They regulate fluid balance, support cellular health, and help keep your muscles, brain, immune system, and nervous system functioning normally.
Sodium
- Helps maintain electrolyte balance.
- Supports normal hydration.
Potassium
- Essential for maintaining fluid balance and hydration.
- Supports normal muscle function.
Fact: Approximately 24% of women and 10% of men fail to consume recommended potassium levels.
Magnesium
Magnesium supports:
- Normal muscle function.
- Muscle relaxation and recovery.
- Reduced tiredness and fatigue.
- Cramp prevention.
Radi8 Chews use Magnesium Citrate, a highly bioavailable form of magnesium that allows superior absorption by the body.
Fact: Up to 60% of adults may not consume enough magnesium, with 10–15% falling seriously below the Lower Reference Nutrient Intake (LRNI).

Suggested Usage
Three chews a day.
One in the morning, one at lunchtime, one in the afternoon.
Morning Chew — Breakfast
Your wake-up call and metabolic ignition.
Helps kickstart your day by supporting energy metabolism from the very first meal.
Lunchtime Chew — Lunch
The 3pm slump antidote.
Perfect for combating the afternoon energy dip.
Evening Chew — Dinner
Supports muscle relaxation, recovery and replenishment.
For best results, take alongside a meal with protein and fibre.
Drink 6 to 8 glasses of water daily. During physical activity, add an extra glass every 30 minutes.
21 chews = 7-day supply (based on 3 chews per day).
If you exercise regularly, sweat heavily or experience fatigue during the day, you may need additional chews to help replenish electrolytes lost through physical activity.

Meet the Founder
Building a New Way to Hydrate.
Radi8 began with a simple belief: everyday wellness should be easier, more enjoyable, and designed around the way people actually live.
After recognising that traditional hydration solutions could often be inconvenient, time-consuming, or difficult to maintain, our founder set out to create something different, a product that combines great taste, convenience, and functionality in a format people genuinely enjoy.
With a passion for innovation and creating products that solve everyday problems, Gurvinder Sunner, Founder & CEO of Radi8, has led the journey from an initial idea into a brand focused on redefining hydration.
Radi8 is more than just a chew. It represents a new approach to building healthier habits, making hydration simple, accessible, and ready for wherever life takes you.
