The reason why mineral premixes are rich in antioxidants is because certain minerals themselves possess antioxidant properties. Antioxidants have the ability to neutralize free radicals, harmful substances produced during the body's metabolic processes. These free radicals can attack cells and lead to oxidative stress, potentially triggering various diseases, including cardiovascular diseases, cancer, and aging.

The antioxidants abundant in mineral premixes, such as selenium, zinc, copper, and manganese, have the ability to neutralize free radicals, reducing the damage caused by oxidative stress to the body. These minerals play a crucial biological role within the body, participating in essential metabolic processes such as antioxidant defense and immune regulation.

In addition, mineral premixes typically include other nutritional components, such as vitamin C, vitamin E, etc. These components also act as powerful antioxidants, working synergistically with minerals to collectively protect the body from the assault of free radicals, maintaining the health and vitality of cells.

Therefore, the richness of antioxidants in mineral premixes is primarily due to the inclusion of minerals with antioxidant properties and other nutritional components. These components work together to safeguard the body from the harm caused by oxidative stress.
