What Are Some of the Best Health Benefits of Antioxidants?
Medically Reviewed by Dr. Nicole Avena


Having a healthy immune system is a key to survival in today’s world.

Your immune system defends against bacteria, viruses, parasites, and other potential troublemakers. These may include molds, food allergens, and environmental toxins.

One of the best ways to protect yourself against such harmful agents is to increase your intake of antioxidants.

What Are Antioxidants?

Antioxidants are compounds in foods that can help prevent or delay damage to cells. They donate electrons to free radicals, which helps neutralize them.

Free radicals can come from outside the body, but they’re also generated by our bodies.

Our cells use oxygen to make energy. In the process, some of the oxygen is converted into free radicals (“oxyradicals”). These must be tightly controlled, or they can destroy DNA, proteins, and other key cell components.

All our cells have antioxidant enzymes for this purpose. Our antioxidant enzyme system includes many different types of enzymes, but in order to neutralize oxyradicals and other free radicals, these enzymes must have iron, zinc, copper, selenium, or manganese built into their protein structure. These various minerals must come from our diet.

We get nutrient antioxidants from our foods – not just vitamins and minerals, but also from thousands of different types of flavonoids and other polyphenols. Foods such as berries, citrus fruits, other fruits, and vegetables provide substantial supplies of these healthy substances.

Antioxidants and Free Radicals

Many have questions about the relationship between antioxidants and free radicals. For optimal physical and physiological function over the long haul, it’s crucial that the body has sufficient antioxidant defense against free radical activity. When the body’s antioxidant defenses lose ground, a situation termed oxidative stress develops.

Our cells’ antioxidant nutrients and enzymes function to neutralize oxyradicals and other free radicals generated from them. But as the body ages, its ability to manage free radicals may decline. This reduction of antioxidant power has been linked to the weakening of brain, heart, immune, and other organ functions.

Benefits of Antioxidants

There are many benefits of eating antioxidant-rich foods. Maintaining this type of diet may:

  • help reduce oxidative stress
  • help eyes, including age-related vision loss
  • help heart health
  • help support healthy aging
  • help prevent serious illness
  • help physical and mental health

Having a healthy diet also may assist with weight management and overall positive mood and well-being.

Types of Antioxidants

There are several types of antioxidants and phytonutrients such as flavonoids, flavones, catechins, polyphenols, and phytoestrogens. Here are just a few of the potent antioxidants that can be found in BrainMD products.

3 Powerful Antioxidants That Can Help Protect Against Free Radicals
