Antioxidant Supplements

What Are Antioxidants & Why Do We Need Them?

Antioxidants are compounds that can prevent and/or slow oxidation and subsequent damage to cells caused by free radicals. Free radicals are highly reactive and unstable molecules that the body produces as a natural by-product of metabolism. Free radicals can be generated as a result of exposure to toxins in the environment, including X-rays, ozone, cigarette smoke, air pollutants, industrial chemicals, or other harmful substances in the environment. While you can get antioxidants through the food you eat, you can also take supplements.

While free radicals have a short lifespan, during that time, they can damage human cells including DNA, causing various mutations that can accelerate the aging process and increase your risk of health conditions like heart disease and cancer. This is why an antioxidant-rich diet and supplements are essential to neutralize unstable, reactive oxygen species and reduce their chances of causing damage. Antioxidants are found in certain foods, including vegetables, fruits, omega-3-rich fish, and green tea. Nutrient antioxidants include vitamins A, C and E, copper, zinc, and selenium minerals, as well as a wide range of phytonutrients. Some of the most potent and well-researched antioxidants include: beta carotene, carotenoids, curcumin, astaxanthin, glutathione, N-acetyl cysteine, alpha lipoic acid, resveratrol, and many others. Eye antioxidants are also a favourite for many as a way to take care of your eye health

Benefits Of Antioxidant Supplements

  • Enhances Cellular Energy Production
  • Helps Guard Against Cell Damage/Oxidative Stress
  • Helps Prevent Premature Skin Aging
  • Protects Cellular DNA 

Who Needs Antioxidant Supplements?

A quality antioxidant supplement may be recommended to improve energy production and resistance to oxidative stress, and to slow the aging process and protect the body against the onset of age-related degenerative diseases, including: atherosclerosis, cardiovascular disease, arthritis, age-related macular degeneration, hypertension, cardiovascular disease, and neurodegenerative conditions. An antioxidant supplement may also be recommended to protect skin health against UV radiation by slowing down the visible signs of skin aging and improving scar tissue and skin healing.

Antioxidant Potencies & Formats

Antioxidant supplements are available in various formats, including tablets, capsules, powders, and liquids. Many are also offered in novel delivery forms, such as enteric coatings, liposomal liquids, and sublingual lozenges. The potency and recommended daily dose will vary according to the individual antioxidant. Always refer to the label instructions for dosing recommendations.  

Final Thoughts on Buying Quality Supplements

There is a wide variety of antioxidant supplements on the market, each offering distinct health benefits and enhancing the body's antioxidant protection. The best antioxidant supplement for you can be determined by speaking to the knowledgeable staff and your favourite health food store. You can buy most antioxidants here at National Nutrition.ca both in-store and online. 

An antioxidant supplement is generally recommended to be taken right before or after a meal to reduce the chance of stomach upset. Antioxidants may be either water or fat-soluble. If you’re taking a fat-soluble antioxidant, it should be taken with a fat-containing meal or snack to optimize absorption.
