Longevity is proven to be a single product that comprises HGHR and 2-AEP. These two effective components are admired as the best anti-aging element available in the world. It is an ultimate formula to tighten and tone sagging skin and turn the clock again several years back, when you were quite young and charming.

The fact why you get old soon or why your skin gets dull and sagging at the very early stage is mental stress and toxic environment. As you age free your skin become sensitive and the free radical from the environment keeps on attacking your skin, which breaks cells of the skin. It causes the appearance of aging spots. Sometime due to the reduction of the moistures, your skin gets thin. It causes the appearance of fine lines and wrinkles on your skin. Too much mental stress is one of the factors that are making you look older.

Free Radicals and Your Longevity

Copyright (c) 2008 Stephen Lau

Many people are afflicted by cancer, autoimmune and other degenerative diseases, which are enemies of longevity. The key to longevity is to protect yourself from free radicals, which damage your immune system, making you susceptible to disease and degeneration.

The human body is composed of cells, which make up your tissues and body organs. Most of these cells replicate themselves, while some do not divide themselves, such as heart cells and neurons in the brain. Human cells require both energy and oxygen in order to function optimally.

One of the reasons why you age is that your body cells are attacked by free radicals.

Free radicals are a natural byproduct of everyday reactions that produce energy for your body. The energy is produced by reactions between many substances and oxygen in your body.

The free radical theory of aging was first introduced by Dr. Denham Harmon in 1956. According to Dr. Harmon’s theory, your body is composed of negatively and positively charged molecules, which form your skin, brain and other body organs. These negatively and positively charged molecules must be balanced or neutral in order to provide a healthy environment for cell renewal and rejuvenation.

Molecules, including oxygen, fatty acids, amino acids, and DNA, are basic components used to build and repair your body cells. These molecules are held together by electrons. Stable molecules have electrons that are paired. When a molecule does not have a pair, it becomes extremely reactive, and begins searching for a pair to make it stable. Basically, it will do just about anything to find a partner, including stealing and damaging other molecules. When a stable molecule loses an electron, it becomes a free radical, which then steals an electron from another stable molecule, causing that molecule to become imbalanced, and so a chain reaction ensues. Disease and degeneration occur when there is imbalance in molecules. Having an electron deficit, due to the imbalance, molecules can be extremely reactive and damaging to body proteins and fats, in particular the DNA.

There are several types of free radicals created by the environment, and oxygen free radicals are the most damaging ones, especially to your DNA and cell membranes.

As you age, your immune system weakens, as evidenced by frequent incidence of infections and influenza. This is because your B- and T-cells in your immune system become inhibited when they are frequently exposed to oxidizing compounds of oxygen free radicals.

The cumulative damage to your DNA as a result of exposure to free radicals is a major cause of many human cancers.

When you are over sixty, you may have a higher risk of cataracts, which is a clouding of the lens in the eye, resulting in blurry vision. Fortunately, vitamins C and E, and carotenoids have strong preventive effects on cataracts.

Another damaging role of oxygen free radicals is their impact on cardiovascular diseases. When your LDL or “bad cholesterol” is attacked by free radicals, it becomes more easily attached to the walls of your arteries, forming plaques that block the flow of blood to your heart. These hazardous conditions are often precursors of heart attacks.

Finally, the neurons in your brain can be damaged by oxygen free radicals. The damage to the neurons may be irreparable because neurons, unlike other body cells, cannot replicate themselves.

Cataracts, heart diseases, cancer, brain damage, and a weakened immune system are all related to aging.

The good news is that the antioxidants present in some foods rich in carotenoids (carrots), flavonoids (onions), vitamins C and E are most effective in fighting off and neutralizing oxygen free radicals.

Does Resveratrol Act As An Anti-Aging Supplement To Enhance Longevity

Resveratrol is a chemical that is found naturally on the skin of red grapes, of the polyphenol family that includes such other members as the powerful antioxidants anthocyanadin and the flavanoids. They destroy free radicals that are responsible for many ill effects in the body, including cardiovascular disease and aging. Aging occurs through the destruction of body cells that free radicals initiate, and can theoretically be retarded by the destruction of the free radicals.

Free radicals are becoming more common invaders of our bodies due to their increasing concentration in the atmosphere through vehicle and aircraft emissions, and also of our seas and rivers through industrial effluents. Free radicals are also created by excessive radiation, such as the harmful UV content of sunlight that is no longer effectively filtered by an adequate ozone layer.

Resveratrol is known to be effective against cardiovascular diseases due to its anti oxidant properties, and also for other reasons, but it is also believed to be a possible anti-aging supplement, to beat off the effects of old age. There is the obvious reason of it being a very powerful anti-oxidant and so preventing cell damage through the effects of free radicals, but there is more to it than just that.

The French do not seem to possess a longevity beyond that which could be expected from their diet high in saturated fats and alcohol. The fact that most of that alcohol is in the form of wines, especially red wines, is significant, but their high cheese intake with its cholesterol and saturated fat content, and other highly saturated animal fats, would be expected to cause a much lower average life expectancy that that which is actually normal in the area.

Although resveratrol is commonly found on red grape skins, and is a constituent of red wine, the quantities are small and it is the Japanese Knotweed that is the major natural source. Resveratrol is currently manufactured from knotweed, which is the main source of the supplement in health food stores. In fact you can purchase online what is described as ‘>99% pure knotweed Resveratrol that is not contaminated with plant residues.’ A lot depends on your viewpoint I suppose!

Perhaps the biggest contribution to be made to longevity by resveratrol is that it can activate the SIRT1 gene. This is the gene that activates the protein and enzyme sirtuin. Sirtuin is thought to be what is loosely terms a ‘protector of cells’ and helps cells to repair themselves when they are close to destruction. When the cell is not sure whether to carry on with the struggle or just give up and die, sirtuin persuades it to fight on and to repair itself. Without the sirtuin, the cell would have died, and as cells die, one ages.

However, the amount of resveratrol found in red wine is insufficient to activate the SIRT1 gene that has to be active before the sirtuin is activated, and supplementation is generally needed. The SIRT1 gene is also activated by a calorie reduced diet, and this can also help to protect cells from dying under stress. Such diets are useful in some situations, but will not necessarily prolong life for those that adopt it.

The SIRT1 enzyme is also thought by some to increase the activity of the mitochondria, the power packs inside cells that provide them with energy by processing fats. Mice fed with resveratrol appeared full of energy that was consistent with a surge in the number and efficiency of the mitochondria within their body cells. This is supported by an increase in muscle tissue. If this is true, and studies on this are continuing, then resveratrol fed to humans could also increase their energy as they age, since the aging process coincides with a reduction in the number and efficiency of the mitochondria within the cells.

This could also tie up in a way with the calorie controlled diet, since an increase in the metabolism that comes with increased mitochondria activity results in a higher calorie uptake, and so a reduction in the free calories available in the body. However, one of the mysteries of the human body is that what makes logical sense does not necessarily work in fact, and so the jury will remain out until the results of the large number of studies underway have been published.

For example, more evidence is required to prove the mitochondria activity theory unequivocally although all of the evidence so far tends to support it. At the moment resveratrol has restricted known uses, though the evidence is being collected and accumulated to provide support for the theories that exist on its ability to help us live longer and with more energy.

As more studies are carried out over the next few years, it seems highly likely that many more beneficial effects will be discovered, and those we are aware of confirmed by scientific proof. Resveratrol has many medicinal properties in addition to its beneficial effect on aging, such as its antioxidant properties, and ability to destroy free radicals, its anti-inflammatory properties where it is of benefit in the treatment of conditions such as arthritis and other inflammatory conditions, and also its effect as an antiseptic agent.

It is already known to increase the longevity of fruit flies, yeasts and worms and results on mice are just as encouraging. The theory behind its effect on human longevity is valid science, and it is known that if cells have a longer time to repair broken DNA, then they are able to do so. The enzyme sirtuin does this, and that is activated by the SIRT1 gene that is turn is activated by resveratrol. So the theory works, and so far laboratory tests are supporting this theory.

Whether or not resveratrol helps us to live longer or look younger as we age is not yet known, but studies are under way. Since the material is natural and not a prescription drug, there is nothing to prevent you from using it, but you are advised to consult your doctor before trying out medication that you have not taken before.
