C Extra 500 mg Plus 500 mg Bioflavonoids 500 mg

Feature Summary

Vitamin C is necessary for maintaining all collagen structures, and it promotes wound repair, strong bones and teeth, and healthy gums. As a powerful antioxidant, it protects the aqueous areas of the body (including the blood, intracellular fluid and interstitial fluid) from free radicals and the damage they cause. Vitamin C protects LDL cholesterol from oxidation and also helps to regenerate vitamin E.

As a water-soluble vitamin, the body does not store vitamin C so regular supplementation is vital. The body's need for vitamin C increases during times of stress because vitamin C participates in the production of vital chemicals such as norepinephrine, which produces the "fight or flight" response. Vitamin C also acts as a detoxifier, helping to cleanse the body of toxins, such as cigarette smoke, carbon monoxide, etc.

Bioflavonoids (vitamin-like molecules that are found in the peel of citrus fruits and other fruits and vegetables) enhance the activity of vitamin C and may improve the body's ability to hold and absorb vitamin C by 35 per cent.

Contraindications

• Vitamin C may increase the absorption of aluminum from aluminum-containing antacids such as AlternaGEL, Amphojel, Basaljel, Nephrox, Maalox, and Mylanta. Take vitamin C at least 2 hours before or after taking one of these products.
• As this product contains citrus bioflavonoids, there is one caution: bioflavonoids are non toxic so drug interactions are virtually unknown; however, citrus bioflavonoids contain grapefruit flavonoids that may interact with certain medications.
• The reason that grapefruit is problematic with certain drugs is that it contains high levels of a flavonoid (plant pigment) called naringin.
• This substance reduces the activity of a group of P450 enzymes known as CYP3A enzymes.
• These enzymes are the ones your body uses to break down certain drugs, such as calcium channel blockers (used in the treatment of high blood pressure), sedatives (for example, midazolam), cyclosporin (an immune suppressant given to people who have received organ transplants) and statins (lipid-lowering drugs).
• If the drugs are not metabolized, they remain in the body in higher concentrations. This increases the risk of unwanted toxic effects.
• If taking these drugs be aware of this effect and consult your health care practitioner.
