Herbs and spices are an excellent source of antioxidants. It’s important to consume antioxidants as they help to reduce the effects of oxidative stress on the body. 

In this article, we’ll review a list of herbs high in antioxidants as well as the health benefits of antioxidants.

Antioxidant Overview:

Antioxidants are important molecules that neutralize free radicals in the body. Free radicals are unstable cells which are created when we experience harmful external factors, like pollution and damaging sun rays.

Free radicals cause oxidative stress, which is linked to numerous health conditions, like Alzheimer’s disease, heart disease, cancer, depression, multiple sclerosis, and memory loss. 

The National Institute of Health and Aging (NIH) created a method called the ORAC (Oxygen Radical Absorbance Capacity) score to measure the total antioxidant capacity of foods.

Scientists and health experts note that 3,000-5,000 ORAC units per day is ideal for health and wellness.

Since antioxidant absorption varies, it’s essential to include a diverse diet of antioxidant rich foods such as fruits, vegetables, and herbs in your daily diet.  

Herbs High in Antioxidants:

Below is a list of antioxidant rich herbs. Add these to your diet to improve your daily antioxidant intake.

antioxidant rich foods - clove

Health Benefits of Antioxidants:

Antioxidants are naturally-occurring molecules that are found throughout nature. They are essential in preventing damage caused by free radical molecules. Sources of antioxidants include water, soil, plants, and animals. 

These molecules take many forms, including vitamins E and C, selenium, zinc, manganese, glutathione, carotenoids, coenzyme Q10, lipoic acid, flavonoids, phenols, polyphenols, phytoestrogens, and many more. Humans usually ingest them through eating fruits, vegetables, and herbs with a high antioxidant content.

Some of the best sources of antioxidants include berries, carrots, peppers, leafy greens, seafood, and many antioxidant rich herbs.

Antioxidants, like vitamin C, are not fat soluble, meaning your body can’t store them for later. So it’s crucial to replenish stores daily.    

Antioxidants are responsible for neutralizing free radicals that cause oxidative stress and long-term health issues. Since free radicals have an unstable amount of electrons, they steal electrons from other cellular molecules, damaging the cell in the process. Antioxidants give the free radicals one of their own electrons, turning off the chain of destruction and reducing the likelihood of oxidative-stress-related complications.   

Research demonstrates that the body can effectively metabolize and use 3,000-5,000 ORAC units per day.

Although the body can store various antioxidants in the body for future use, due to the constant excretion of molecules, it’s important to maintain a steady supply of antioxidants to manage oxidative stress. 

How Many Antioxidants Should I Consume Per Day?

There is no daily antioxidant requirement per day; however, it’s essential to ingest antioxidant-rich sources to counter oxidation in the body. 

Below is a helpful chart.

Age GroupRDA (ORAC units (µmol) /day)
Men (2,500 calories/day)11,000 units 
Women (1,800 calories/day)8,000 units 

It is important to note that these are the recommended daily allowances, which are the minimum amount of a nutrient a person needs to avoid future complications. Some individuals may need more or less depending on their needs and health conditions.


Supplementing with antioxidant rich foods, especially herbs, supports various processes in the body and may prevent serious health problems like heart conditions, degenerative brain diseases, mood disorders, and cancer. 

Although the body doesn’t require a specified amount of antioxidants, adequate antioxidant levels are vital to avoid inevitable oxidative stress. While dietary supplements are sufficient and available, it’s best to receive antioxidants from natural sources.
