The Best Online Resource On Antioxidants
Antioxidants, whether natural or man-made, are compounds that help prevent cells and tissues from being damaged by reactive oxygen species and free radicals. Often described as scavengers of free radicals, antioxidants hunt down and neutralize substances that cause oxidative stress in the body.
The numerous health benefits of antioxidants are well-documented. For instance, antioxidants are known to help improve male fertility by protecting the sperm from free radicals. Male Ultracore, a potent male sex enhancement supplement, contains several herbal ingredients that are rich in antioxidants.

Types Of Antioxidants
Although the human body also endogenously produces antioxidants, consuming fruits and vegetables that are antioxidant-rich can help improve the body’s natural antioxidant capacity. Examples of antioxidants obtained from plant-based foods include:
Benefits Of Antioxidants
Countless studies have shed light on the various benefits of antioxidants. There are also numerous ongoing studies which aim to identify new antioxidants, measure the effectiveness of antioxidants, and test the effects of antioxidants on various diseases. Here are a few examples of the more well-known benefits of antioxidants.
Oxidative damage to cells is thought to be a causative factor in disease and aging. The culprits are free radicals or reactive species of oxygen, nitrogen or chlorine. Superoxide, hydroxyl ions, hydrogen peroxide, and nitric oxide are examples of free radicals. These are atoms or molecules with an unpaired electron. Free radicals are naturally occurring and an important part of biological functions such as immunity, inflammation, growth and repair. Free radicals can have negative effects when they damage proteins, lipids and nucleic acids. They are normally held in balance in biological systems by antioxidant defense mechanisms. Environmental insults, infections, smoking, radiation and sunlight can also cause the formation of free radicals.
Antioxidant defenses act in concert in cell differentiation and growth, immune responses, cell membrane integrity, and normal DNA repair. Oxidative stress occurs when there are more free radicals than can be dealt with due to environmental insult, disease or malnutrition. Even exercise, because of an increase in oxygen demand and utilization, increases the formation of free radicals. However, regular exercise builds up body defense systems and protects against damage. An improper balance between formation and destruction of free radicals may play a role in degenerative disease and aging. Antioxidants in the diet may prevent disease and deficiencies may be deleterious to fetal and childhood development.
Antioxidant micronutrients must be supplied in the diet. Fruits, vegetables and whole grains are better sources of antioxidants than pill forms, but, in general, supplementation is beneficial. A balanced diet including several servings per day of fruits and vegetables is recommended. We also recommend CBD oil to help with daily nutritional benefits, as well as to help with pain and anxiety.
Most animals can make this vitamin, with the exception of primates, guinea pigs and some bats. The deficiency disease is called scurvy and manifests by numerous defects in connective and epithelial tissue maintenance and repair. Scurvy takes 3-4 months to develop because it takes that long for bodily vitamin C stores to be depleted. The RDA is 60 mg/day but higher doses are well tolerated up to about 1800 mg/day; even if there is no evidence that megadoses are beneficial. Vitamin C has been suggested to be protective against coronary heart disease, presumably because it prevents LDL oxidation.
Flavanoids have been shown to have antiviral, antiallergic , anti-inflammatory, antithrombogenic and anticarcinogenic effects in vitro. Flavanoids act as antioxidants by directly scavenging free radicals, chelating reactive elements such as iron, or by inhibiting oxidative enzymes. Many of the other actions are mediated by their inhibitory action on prostaglandin synthesis and mediators of inflammation. Flavanoids also inhibit tyrosine kinases, many of which are involved in cell growth and proliferation.
Some 4000 flavanoids have been found. There are four main groups of flavanoids; 1) flavones, 2) flavanones, 3) catechins, and 4) anthocyanins. It is the flavones and catechins that appear to be important flavanoids in oxidation defenses.
Perhaps the most important flavone is quercetin found in apples, onions, broccoli and berries. The flavanones are found primarily in citrus fruits and peels. Catechins are found in teas and red wine. Anthocyanins are present in cherries, berries, wine, grapes and tea. No daily requirement for flavanoids has been established, but a balanced diet containing fresh fruits and vegetables, tea, and moderate amounts of red wine is recommended.
