Antioxidants are compounds that reduce or inhibit cellular damage through their ability to neutralize molecules called free radicals. Free radicals are molecules that have one or more unpaired electrons in their outer orbit, making them unstable and highly reactive. The body creates them through normal endogenous metabolic processes, including energy production. The body also produces them in response to environmental and lifestyle factors, such as sun exposure, smoking, alcohol consumption, and more. Antioxidants inhibit a process called oxidation, which generates free radicals that leads to cellular damage. Antioxidants safely interact with free radicals, neutralizing them before they can cause damage to proteins, lipids, and DNA. Oxidative stress occurs when there are too many free radicals in the body. This Free radicals play an important role in the normal physiological functioning of the body and contribute to a person’s health. However, when the body produces an excess of free radicals, it can increase a person’s disease risk. For example, many Cells have antioxidant defense systems that help keep free radical production in check. For example, cells contain antioxidant enzymes that help reduce free radical levels. The primary antioxidant enzymes in the cells These antioxidant enzymes are known as first-line defense antioxidants. They help regulate free radical levels by neutralizing both free radicals and other molecules that have the potential to become free radica...

Antioxidants are substances, artificial or natural, that prevent and slow cell and tissue damage by attacking free radicals, which are molecules that have an unpaired electron. Free radicals are natural byproducts of metabolism and are also generated in response to environmental stressors, such as exposure to pollution or cigarette smoke. But too many free radicals can send the body into disarray, causing oxidative stress, which has been associated with several serious illnesses including cancer, heart disease and some neurodegenerative diseases, such as Alzheimer's and Parkinson's Disease. Antioxidants work to maintain a healthy balance of free radicals and help prevent oxidative stress. How do antioxidants work? Free radicals are molecules that have an unpaired electron, making them highly unstable, as electrons prefer to orbit an atom in pairs. As a result, free radicals "scavenge" other molecules in the body, stealing their outer electrons to become more stable, and damaging the scavenged molecules in the process. Free radicals are formed naturally by the body during metabolic processes, but the body can also be exposed to free radicals produced by external sources, such as X-rays, cigarette smoke and air pollution. The electron-hunting process of free radicals carries some benefits for the human body, according to Harvard Health. For example, when the immune system comes in contact with a pathogen, it sends a surge of free radicals to attack the agent. The free radica...

The three main antioxidant vitamins are Other antioxidants include: • • • • • • Polyphenols • Why You Need Antioxidants Antioxidants may protect your body against Free radicals can build up in your cells and cause damage to other molecules, increasing your risk of cancer and other diseases. Antioxidants may help protect cells against this damage. To balance free radicals and antioxidants in your body, you need to consume 8-11,000 antioxidant units per day. However, research suggests that when it comes to fighting disease, antioxidants are not as powerful as some advertisers claim. Researchers found that vitamin E and other antioxidants didn't protect against However, a diet high in fruits and vegetables is healthy for many other reasons. Foods with antioxidants are typically: • High in • Low in • Full of vitamins and minerals Foods With Antioxidants • Berries The top fruit sources of antioxidants are • Colorful Vegetables Many red, orange, deep yellow, and dark green vegetables contain the antioxidant carotene.

Cleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission. We do not endorse non-Cleveland Clinic products or services. But what are antioxidants? And why are they so important? To get to the bottom of all the buzz, we spoke with registered dietitianNicole Hopsecger, RD, LD. What are antioxidants? “Antioxidants are naturally occurring chemicals in foods that can serve as a defense against The primary benefit of antioxidants is their ability to safely react with free radicals before damage can be done on a cellular level. Basically, “Antioxidants fight free radicals,” says Hopsecger. “Free radicals can damage the body’s cells by changing a cell’s DNA, or it can alter a cell’s membrane,” explains Hopsecger. “This interaction between free radicals and the body is called oxidative stress, which is often thought to be what contributes to the increased risk of developing chronic disease.” Hopsecger says that while fighting free radicals is the primary benefit of antioxidants, there is a secondary benefit. “Indirectly, antioxidants help reduce the risk of chronic disease development because they negate those free radicals from causing havoc to our cells,” Hopsecger says. Antioxidants and your diet While Antioxidant-rich foods Some examples of antioxidants and the foods (and vitamin sources) in which you can find them, according to Hopsecger, include: • Vitamin C:Broccoli, Brussels sprouts, sweet potatoes, bell peppers, tomatoes an...

Topical vitamin C is a science-backed, dermatologist-favorite ingredient that may help slow early skin aging, prevent sun damage, and improve the appearance of wrinkles, dark spots, and acne. Vitamin C is an antioxidant, meaning it fights harmful free radicals (toxins) that come in contact with your skin from external sources like air pollution, or from inside the body as a result of normal processes like your metabolism. Free radicals can damage the skin, and applying topical vitamin C can combat free radicals and may improve the skin's overall appearance. Skin benefits of vitamin C A few clinical studies have demonstrated that vitamin C can improve wrinkles. Vitamin C may also help protect the skin from harmful ultraviolet rays when used in combination with a broad-spectrum sunscreen. Further, vitamin C can reduce the appearance of dark spots by blocking the production of pigment in our skin. In Additionally, topical vitamin C can help with acne through its anti-inflammatory properties that help control sebum (oil) production within the skin. In Where to find topical vitamin C and what to look for on the label Vitamin C can be found in serums or other skincare products. Different formulations of vitamin C can alter its strength and effects in the skin. Consider purchasing vitamin C products from your dermatologist's office or a verified online retailer, with a clinical formulation that contains an active form of vitamin C (for instance, L-ascorbic acid), has a strength o...

Often used as a marketing buzzword, learn about the role of antioxidants beyond the hype, and some of the research on health and disease prevention. Jump to: – – – – – The body’s trillion or so cells face formidable threats, from lack of food to infection with a virus. Another constant threat comes from chemicals called free radicals. In very high levels, they are capable of damaging cells and genetic material. The body generates free radicals as the inevitable byproducts of turning food into energy. Free radicals are also formed after exercising or exposure to cigarette smoke, air pollution, and sunlight. [1] Free radicals come in many shapes, sizes, and chemical configurations. What they all share is a voracious appetite for electrons, stealing them from any nearby substances that will yield them. This electron theft can radically alter the “loser’s” structure or function. Free radical damage can change the instructions coded in a strand of DNA. It can make a circulating low-density lipoprotein (LDL, sometimes called bad cholesterol) molecule more likely to get trapped in an artery wall. Or it can alter a cell’s membrane, changing the flow of what enters the cell and what leaves it. An excessive chronic amount of free radicals in the body causes a condition called oxidative stress, which may damage cells and lead to chronic diseases. [2] We aren’t defenseless against free radicals. The body, long used to this relentless attack, makes many molecules that quench free radic...
