What Do Antioxidants Do? 

The Vital Role of Antioxidants in Protecting Our Cells

Free radicals are highly reactive molecules produced as a normal by-product of human metabolism. When in high concentrations, these highly reactive molecules have the potential to harm cells, including DNA, cell proteins and cell membranes, and may play a role in the development of unhealthy cell growth. Fortunately, antioxidants, wich are healthy compounds commonly found in foods like fruits and vegetables, can help defend the body against oxidative stress and, in turn, help prevent the onset of various chronic degenerative diseases.

Antioxidants are abound in nature and supplement form, with some of the most well-known being: vitamins A, C, and E, alpha lipoic acid, N-acetyl cysteine, resveratrol, glutathione, and curcumin, among others. But it’s important to understand that like many different letter vitamins exist (A, the B family of vitamins, D, E, etc.), there are also many different antioxidants in nature. Each of these is uniquely different, and each offers distinct health benefits. Individual vitamins, like individual antioxidants, can also have a particular affinity for an organ, a system, or a tissue and will offer targeted support to this organ, system, or tissue. This is why when you’re looking for help for a specific organ, single antioxidants cannot be beat. 

Below are some general guidelines to help get you started on your selection of single antioxidants:

Açai – açai berry a nutritional powerhouse and one of the antioxidants with the highest ORAC value (antioxidant capacity). Especially beneficial for brain health and cognition as well as for skin support.

Astaxanthin – an antioxidant that fights free radicals 6,000 times more efficiently than vitamin C, 550 times more efficiently than vitamin E and 40 times more powerfully than beta-carotene.

Bilberry bilberry, an antioxidant-rich and incredibly beneficial to preserve eye health and vision across the lifespan and prevent eye conditions such as macular degeneration, cataracts, glaucoma, etc.

Alpha Lipoic Acid – a powerful antioxidant that is water and fat-soluble, can support every cell in the Body. Especially effective at regulating glycemia, promoting weight loss and helping to prevent neurodegeneration.

Beta Carotene - also known as provitamin A, converts the body to active vitamin A (retinol) according to its needs. Promotes healthy eyes, healthy skin, and strong immunity.

Grapeseed Extract – naturally rich in phenolic acids, anthocyanins, flavonoids, and proanthocyanins. Shown to improve blood flow and circulation and protect cardiovascular health.

Lutein – a unique carotenoid antioxidant that has a particular affinity for the eyes and vision. Lutein is clinically proven to reduce the risk of age-related macular degeneration and other eye conditions.

Lycopene – is considered a cancer-fighting antioxidant and has been the subject of copious research around its benefits for heart disease, diabetes, neurogenerative conditions, and abnormal cell division and growth – most notably that of the prostates’.

N-Acetyl Cysteine (NAC) – NAC supplementation is critical after age 50 since glutathione production decreases as we age, increasing our risk of oxidative damage. NAC is especially beneficial to boost the Body's detoxification and promote optimal lung health.

Pycnogenol – - also called Pine Bark Extract – is typically recommended to help reduce pain and inflammation, enhance blood flow throughout the Body, and promote optimal heart health.

Quercetin – an antioxidant that is used for everything from boosting immunity to improving physical performance, promoting heart disease, and helping to prevent neurodegeneration. Also especially helpful in inhibiting the histamine reaction, so ideal for allergies.

Resveratrol – a powerful compound found in grape skins that acts as a potent antioxidant. Resveratrol promotes heart health, brain health, and circulatory health, as well as helps optimize blood lipid levels.

Superoxide Dismutase (SOD) – supports and strengthens cell health throughout the Body. Improves energy production and resistance to oxidative stress. Often used to help slow the aging process and help prevent the onset of age-related degenerative diseases.

Key Health Benefits of Antioxidants

  • Helps Prevent Age-related Degenerative Conditions
  • Enhances Antioxidant Protection to all of the Body’s tissues
  • Fights Oxidative Stress
  • Protects Tissues, Cells & DNA Against Oxidative Damage 

Diverse Potencies & Formats: Finding Your Ideal Antioxidant

Single antioxidant supplements are offered in various delivery formats, including tablets, capsules, softgels, and liquids. The potency and recommended dose will vary depending on the antioxidant in question. Always follow the dosing instructions on the product label. 

Guide to Selecting the Perfect Antioxidant Supplement for Your Needs

Single antioxidant supplements can significantly impact your overall health and wellness. If you're struggling with specific health issues, paying attention to the antioxidant you select is essential to ensure it is best suited to your health status and goals. Spending a little extra time online researching the different antioxidants is undoubtedly worthwhile, as is chatting with the knowledgeable staff at your favourite health food store or online supplement retailer, who will happily offer a little guidance.
