Absorption
Bionic magnesium, calcium, and bicarbonate that are easily absorbed due to their natural, ionic form. Maximum bioavailability for over 75% absorption.
Synthetic minerals in pill or powder form, often poorly absorbed and less effective. Many people only absorb 20-30% of the minerals in supplements.
Source
Sourced from an untouched European spring, 100% natural with minerals formed over thousands of years.
Artificially produced in labs, often with added chemicals or fillers that the body doesn’t absorb as efficiently.
Additives & Preservatives
Completely additive-free. Only pure minerals in their natural form with no preservatives or chemicals.
Often contain binders, fillers, and other artificial additives that may cause digestive issues or allergic reactions.
Health Benefits
Consistent, long-term benefits like improved hydration, muscle function, better sleep, and overall wellness. Minerals that are essential for your body to function at its best.
Often used as quick fixes for deficiencies but don’t provide long-term support. Can also cause imbalances if overused.
Sustainable
Comes in a bottle made from sustainable materials, and the water itself is naturally replenished, eco-friendly, and sustainable for the future.
Often packaged in plastic bottles or containers that contribute to waste, with the ingredients produced using unsustainable practices.
