It seems like antioxidants are everywhere, from juices to skin creams to sunscreen. We know they’re good for us, but have you ever wondered why that is and what they do?
What are antioxidants?
Long story short, antioxidants are natural, plant-derived compounds that protect our cells from and minimize the damage caused by free radicals. Free radicals are charged, highly reactive molecules that get produced via oxidation—which occurs when your body breaks down food or is exposed to medications or toxins like cigarette smoke, pollution, and ultraviolet (UV) radiation.
What’s so bad about free radicals?
While free radicals aren’t all detrimental (in fact, oxidation is necessary for life), the accumulation of free radicals—if we don’t have enough antioxidants to deal with them—brings on oxidative stress.
As the National Center for Biotechnology Information (the division of the National Institute of Health that specializes in molecular biology) puts it, oxidative stress “plays a major part in the development of chronic and degenerative illness such as cancer, autoimmune disorders, aging, cataract, rheumatoid arthritis, cardiovascular and neurodegenerative diseases [source].” In other words, it encompasses all the unhealthy conditions we don’t want.
How do I get more antioxidants?
Plants and animals all have some naturally occurring antioxidants and enzymes that minimize or repair the damage to cells from oxidative stress, but the more harmful free radicals the body is exposed to and that build up, the harder it is to keep up.
Plant-based foods (fruits, vegetables and their juices, whole grains, nuts, seeds, herbs, and spices, and even chocolate) are the best natural antioxidant sources [source], although some are also found in small amounts in meat, seafood, and dairy, coming mostly from the plant foods they eat or supplements [source]. As a bonus, most of the antioxidant-rich, plant-based foods are high in fiber, have no saturated fat and cholesterol, and are good sources of vitamins and minerals [source].
Antioxidants are also effective when applied topically, and they are just as important for skin, eyes, and hair as they are for our other organs and systems, which is why you also see them in beauty products and sunscreens [source]. (You’ll often see vitamins A, C, or E included in face creams and serums and zinc in many sunscreens.)

Ashwagandha KSM 66 says
Adaptogens are herbs that reduce fatigue and the toxic effects of stress. They’re called adaptogens because they adapt to what the body needs, regulating the body rather than pushing it in one direction or the other. <a href="https://nuturawellness.com/collections/adaptogens/products/ashwagandha-ksm-66-liquid">Ashwagandha KSM 66</a>, ginseng and eleuthero are the three most powerful regulators of adrenal activity and can be used long or short term to address skin conditions.

Great list and content – so refreshing to see them actually broken down into their chemical components like this, very helpful x
So I take it it’s mainly berries that are ful of anti-oxidants. Does it make any difference if they’re in a smoothie?
