Anonymous: Hi, my friend recently decided taking this unusual type of vitamin supplement called "Two stage times release Vitamin C 1000 mg". Could you explain what the supplement is made up of?

Basically this is a vitamin C supplement which has antioxidant properties in it. It claims to give 24 hour antioxidant protection by releasing half of the vitamin C at the start of ingestion and then 12 hours later releasing the rest of the vitamin C supplement. The supplement fact states that it has Vitamin C (as ascorbic Acid, rose hips, acerola cherry). Ascorbic acid is a form of vitamin C that humans do not produce naturally and must consume in their diets. It as well prevents scurvy which is a vitamin C deficiency. It also contains Vegetable Cellulose Capsule, Cellulose, Magnesium Stearate, Stearic Acid and Silica. Vegetable cellulose aids in peristaltic movement in the intestines, stearic acid and magnesuim stearate is the waxy coating inside a tablet to allow for the dry ingredients to be inserted easily and also hold the capsule together and aids in the release of the capsule when ingested. Silica helps in the sufficient intake of the pill as well as promotes strong bones. Two Stage Timed Release Vitamin C 1000 mg

Thanks for the question! Hope this is of help!

Effects of Antioxidants in Cellular Respiration

Oxidization is the loss of an electron by an atom/molecules. Oxidants developed within our bodies form aerobic respiration creating a by product of free radicals (and atom or group with an uneven pair of electrons). Antioxidants essentially fight off/ prevent oxidization.  When oxygen is being reduced in the electron transport chain, this was due to it reacting to a substance creating free radicals. Antioxidants then render them to be harmless. 

During Pyruvate Oxidization in Cellular respiration, the oxidization of pyruvate reduced NAD+ to NADH. The NADH’s electrons are used to make energy (a.k.a ATP). In this process free radicals are produced and therefore antioxidants play a role in cellular respiration to decrease the damage of these free radical byproducts.

The Effects of Antioxidants on the Body

Antioxidants are nutrients as well as vitamins that stop the damage of oxidization in animal tissues which occurs when free radicals create chain reactions. Free radicals have one or more unpaired electron therefore making them very unstable. As they search across ones body to take or donate electrons, they damage cells, proteins and DNA. Antioxidants neutralize these radicals by either providing an electron or by breaking it down to stop its damage.

Some positive claims that antioxidants have are:

-Promoting brain health, due to the fact that antioxidants are found in plentiful amounts of fruits, vegetables grains and whole grains keeping the brain healthier as one ages

-Vision; studies found that consuming vitamins A, C, Zinc and Copper reduce 25% of a person’s chance to loose vision when aging. 

-Cancer; Studies are not accurate but there are many promising signs that antioxidants prevent cancer due to their ability to reduce cell damage which increases cancer.

Scientific evidence refuting antioxidant supplements

Recent experimental evidence is suggesting that free radicals are triggering an endogenous response to help aid against eternal radicals and other toxic compounds. As a result the free radical production extended the life span of the Caenorhabditis elegans (worm in the animalia kingdom used for research and as a model organism). Therefore antioxidants are preventing life span allowing proof that toxic radicals are indeed helping the expediency of life and improved health effects.

There is little evidence of whether or not antioxidant supplements actually help in the prevention of chronic diseases. There have been observational studies of people taking higher intakes of fruits and vegetables filled with antioxidant which links them to having a lesser chance of certain diseases but it isn’t certain whether or not these benefits are from antioxidants. Although biochemistry labs of antioxidants suggest that there is a benefit, studies have found no benefits.

Several long term studies supporting that there is not benefits in antioxidants:

· The Physicians Health Study II, which included more than 14,000 healthy male physicians aged 50 or older, found that neither vitamin E nor vitamin C supplements reduced the risk of major cardiovascular events (e.g., heart attack, stroke, or death) or cancer.

· The Selenium and Vitamin E Cancer Prevention Trial (SELECT)—a study of more than 35,000 healthy men aged 50 or older—found that selenium and vitamin E taken alone or together did not prevent prostate cancer. (Two earlier reviews suggested that preliminary evidence for selenium appeared promising). A 2011 updated analysis from this trial concluded that vitamin E supplements significantly increased the incidence of prostate cancer in healthy men. At a median followup of 7 years, the researchers observed that the incidence of prostate cancer was increased by 17 percent in men who received the vitamin E supplement alone compared with those who received placebo. There was no increased incidence of prostate cancer when vitamin E and selenium were taken together.

· The Women’s Health Study, which included almost 40,000 healthy women at least 45 years of age, found that overall, vitamin E did not reduce the risk of death, major cardiovascular events (e.g., heart attack, stroke, or death), or cancer. However, it was associated with reduced deaths from cardiovascular causes and also reduced major cardiovascular events in a subgroup of women aged 65 or older.

· The Women’s Antioxidant Cardiovascular Study found no beneficial effects of vitamin C, vitamin E, or beta-carotene on cardiovascular events (e.g., heart attack, stroke, or death) in more than 8,000 female health professionals, aged 40 years or older, who were at high risk for cardiovascular disease.

Natural Resveratrol - “Age Off ”

On the General Nutrition Centers Web site, Natural Resveratrol’s product “age off” claims to prevent free radical damage, protective support to the cardio vascular system, reducing stress and fatigue, achieve a slim toned body and makes skin look younger. But the footnote at the end of their description claims that “These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”

http://www.gnc.com/product/index.jsp?productId=12089813&kwCatId=


 Resveratrol is available in supplements and pills frequently combined with vitamins however one must be cautious because dietary supplements are very loosely regulated and aren’t approved by the FDA. The research on resveratrol has only been focusing on the short term effect and is majorly tested by invitro not on humans. Not a lot is known about the effects it has on its liver and the absorption of the supplement and the overall long term effects. There is no scientific evidence therefore proving the effects of aging and the effects of it being taken in large doses along with the fact that there is no dosage recommendation. It would be healthier and safer to eat a balanced diet that contains fruits and vegetables instead of taking the supplement.
