  • This supplement contains no wheat, gluten, soybeans, dairy, egg, fish/shellfish, peanuts/tree nuts or other known and common allergens.

Individual Antioxidant Supplements

Carotenoids aren't the only beneficial antioxidants to consider. Seven key supplements you may want to consider include:

Vitamin E

Vitamin E is one of the most important antioxidant supplements to consider taking for prevention of disease.

  • Vitamin E boosts the immune system to fight off invading bacteria and viruses.
  • It helps widen blood vessels, keeping blood from clotting within them and reducing the risk of artery-clogging atherosclerosis.

  • It may also improve physical endurance by increasing energy, and reducing muscle damage after exercise.
  • Vitamin E supplements may help reduce premenstrual syndrome symptoms and hot flashes.

Product Recommendation

Carlson Labs - E-GEMS PLUS 400 IU is one of the best products because it contains d-alpha-tocopherol, which is vitamin E derived from natural food sources, making it more easily absorbed by the body. This supplement comes in a soft gel form, which makes it easy to swallow. Carlson Labs is also rated by ConsumerLab.com as one of the top-rated vitamin and supplement brands.

Vitamin C

Vitamin C is an essential nutrient with antioxidant functions. According to Natural News, "there is not a known virus that can survive in the presence of this essential antioxidant."


  • Vitamin C (also known as ascorbate or L-ascorbic acid) has been shown to be able to detoxify the body and kill cancer cells.
  • Vitamin C helps in wound healing, improves the absorption of iron and helps the immune system work properly, protecting the body from disease.

Product Recommendation

Solaray's Vitamin C is an excellent choice for vitamin C supplementation because of its time-release formula. This formula releases half of the vitamin C in each capsule rapidly and the other half gradually over a period of up to 12 hours. This is important because Vitamin C is a water-soluble vitamin, meaning that the body absorbs what it needs and discards the rest. People need a constant supply of vitamin C in order to get its full benefits.


Selenium works as an antioxidant since it helps fight free radical damage to cell membranes and DNA.


Product Recommendation

Swanson Premium's Selenium - (L-Selenomethionine) is a great choice because it contains the organic form of selenium, which is absorbed at a 90% rate and is retained. Additionally, both ConsumerLab.com and MDJuction websites rate Swanson vitamins very high.


Cranberries are one of the top foods proven to have health benefits and are chock full of antioxidants. While eating cranberries is the ideal way to enjoy these benefits, supplements are also a good option.

Zinc is a mineral with powerful antioxidant benefits, though it's important to avoid exceeding the recommended dosage.

  • Zinc helps to make proteins and DNA, thus helping in wound healing.
  • Dr. Mercola states that zinc is important for proper senses of taste and smell, and helps prevent and treat psoriasis, eczema, and acne.

Product Recommendation

Zinc Balance from Jarrow Formulas is an excellent choice due to its combination of Zinc and Copper in a 15:1 ratio.

Vitacost customers rate this product highly, describing it as an affordable and effective low-dosage zinc supplement.


Resveratrol is an antioxidant found naturally in red grapes and wine, and its health benefits are significant.

Co-Enzyme Q10

Coenzyme Q-10 (CoQ-10) is a vitamin-like substance found throughout the body, especially in the heart, liver, kidney, and pancreas. It can also be made in a laboratory and it is used as medicine. CoQ10 levels decrease with age and certain medical conditions, so supplementation can be important.


  • CoQ-10 is used for cell growth and for protecting the cells from damage that could lead to various forms of cancer.
  • It also helps the immune system work better.
  • It can help with the treatment of Alzheimer's disease.

Product Recommendation

The Co Q10 400 mg Ultra Formula by 21st Century is the only supplement with the same dosage used in most studies testing the effectiveness of this substance, making it an excellent choice in general. However, be cautious, as supplementation with CoQ-10 should be personalized and adjusted by your physician. The company 21st Century is ranked high among supplement-producing companies by ConsumerLab.com.

Avoid Excessive Dosages

Accidental overdose of antioxidants can occur. It's important to realize that anything above the recommended daily intake may actually cause more harm than good. One good example is vitamin A, which can be beneficial for liver diseases, cystic fibrosis, Crohn's disease and much more. However, vitamin A should be taken with caution, especially with supplementation, as there is some evidence that it might increase the risk of hip fractures and some birth defects. It may also interfere with the beneficial actions of vitamin D and an overdose could even lead to death.

Choose Carefully

Remember that supplements are intended to - as the word says - 'supplement' a healthy diet and a regular exercise routine, and not replace food intake. If you decide to take any these supplements, make sure you read and follow the label instructions carefully. Always check with your health care provider about the supplements' safety and whether they have any particular interactions with your medications.
