Description

Designed as the perfect introduction to natural supplements for runner's, the Runner's Intro Bundle supports strong bones, faster recovery, optimise hydration, and help you feel your best every step of the way.

Why we made this product

We created the Vitamin D + K2 supplement for athletes and individuals who may be deficient in these essential vitamins. Low Vitamin D levels can impact muscle recovery, bone strength, and immune function. With this product, we aim to ensure that athletes and active individuals are provided with a high-quality, plant-based Vitamin D3 and K2 formula, tailored for their needs.

Hydration is crucial for maintaining performance, particularly during intense or prolonged physical activity. Electrolytes like sodium and potassium are essential to prevent dehydration and muscle cramps, which are common issues in endurance sports. Puresport’s Ultra Electrolytes is designed to keep athletes hydrated, improve endurance, and support muscle function with a sugar-free, refreshing citrus formula.

Together, the Intro Runner's Bundle provides the perfect supplements to start your running journey, optimising hydration and supporting bone, muscle and immunity to help prevent injury.

Only what you need, nothing you don't

Vitamin D3

Sourced from marine algae, supports immune function, bone health, and recovery from intense exercise.

Vitamin K2 (MK-7)

Works synergistically with Vitamin D3 to ensure calcium is deposited into bones, reducing the risk of arterial calcification.

SODIUM CHLORIDE

Sodium is critical for maintaining fluid balance and enabling muscle contractions. It is the most important electrolyte lost through sweat and essential for performance during prolonged exercise.

POTASSIUM (CHLORIDE)

Potassium works with sodium to maintain fluid balance and muscle contractions.

MAGNESIUM (CITRATE)

Magnesium supports muscle function and reduces fatigue by regulating electrolyte balance.

Rigorously tested

All of our products are Informed Sport certified, undergoing rigorous batch testing to ensure they are suitable for use by professional athletes.

  • Time taken to feel the benefits of this product differ between individuals. Benefits of taking Vitamin D3 are usually felt from between 4-12 weeks of consistent use.

    The time it takes to feel the benefits of Ultra Electrolytes can be relatively quick. Immediate effects are usually felt from 30mins - 1 hour. Longer term cumulative benefits can be noticed from a week of consistent use around intense exercise.

  • 4000IU is a strong dosage of Vitamin D3. We would recommend consulting a doctor before consuming other products also containing Vitamin D3. I

    In our range, Ultra Magnesium contains 1000IU of Vitamin D3.

  • Our Vitamin D3+K2 supplement is of higher strength (Vitamin D3 4000IU). If you find the 4000IU strength too high, you can opt to take them once every 2-3 days instead of daily. This approach can be effective because both Vitamin D3 and K2 are fat-soluble, meaning they can be stored in the body's fat tissues and liver for future use.
