OXIDATIVE STRESS
WHY IS IT IMPORTANT?
Every day, your body fights off harmful molecules called free radicals. Free radicals come from things like pollution, stress, and even the food you eat. When your body has too many of these free radicals, it causes something called oxidative stress. this causes damage to your cells and can lead to a variety of diseases.
______________________________________________________

INCREASE ABSORPTION
WHY IS IT IMPORTANT?
Increasing absorption in the gut is crucial because it ensures the body efficiently utilizes nutrients from food or supplements, to support overall health. It enhances energy levels, boosts immune function, and promotes digestive health.
______________________________________________________
HYDROGEN'S IMPACT
Molecular hydrogen enhances nutrient absorption by reducing oxidative stress, which can improve nutrient uptake and support a balanced gut microbiome. By creating a healthier gut environment, it helps your body absorb vitamins and minerals more efficiently, maximizing the benefits of the nutrients you consume.
