What are Hydro Hydration Immunity Sachets?

Hydro Hydration Immunity Sachets are advanced hydration drinks designed to support both fluid balance and immune health in one convenient formula.

They combine essential electrolytes with targeted immune-support nutrients to help you stay hydrated, resilient, and ready to take on busy days, travel, training, or seasonal challenges.

How are they different from standard hydration products?

Most electrolyte drinks focus purely on hydration.

Hydro Hydration Immunity Sachets go further by supporting:

  • Immune system resilience
  • Daily nutrient intake for immune function
  • Gut-immune connection
  • Hydration and mineral replenishment

It’s a dual-purpose formula - hydration plus immune defence.

How do they support immunity?

The formula includes key nutrients known to contribute to normal immune function, including Vitamin D3, Vitamin C, and Zinc.

It also contains Wellmune®, a clinically studied beta glucan that helps support immune readiness and the gut-brain-immune axis - an important connection in overall immune health.

Together, these ingredients help your body respond effectively to daily stressors.

What does Chaga do?

Chaga mushroom is traditionally used for its immune-supporting properties.

It’s included to provide additional antioxidant and immune support, helping you stay strong during demanding periods, seasonal changes, or times of increased stress.

Is it vegan and allergen-free?

Yes. Hydro Hydration Immunity Sachets are 100% vegan and free from common allergens, making them suitable for a wide range of dietary needs and lifestyles.

If you have any concerns then please contact contact@fourfive.com

Are these only for when I am ill?

No. This is about supporting hydration and everyday immune function, not treating illness. It is designed as a proactive daily habit.

Will it break a fast?

No. Each sachet contains fewer than 10 kcal and is sweetened with stevia, meaning it has minimal impact on blood sugar levels and is suitable for most fasting routines. However this can vary depending on your individualised approach.

When should I use Immunity sachets?

For best results, take:

  • Daily during high-stress or busy periods
  • During travel
  • Through seasonal changes
  • When increasing training load

Simply mix with water for convenient hydration and immune support in one step

Are they Informed Sport tested?

Yes, the sachets have been tested and approved by Informed Sport.
