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.

What are free radicals and should I be concerned about them? Are they for real?


I have heard about the Free Radical Theory of Aging, and want to know whether there is anything I can do about aging or should I just sit on the couch and relax???

Free radicals are molecules that have lost an electron and so they seek out stable molecules and steel one of their electrons making that molecule unstable. This can cause a chain reaction when this newly damaged molecule seeks out a new electron. These free radicals can cause damage to healthy cells if there isn't enough antioxidants to get rid of them. Antioxidants, such as vitamin C and E can help keep free radicals under control.

Description

Lipoic Acid is a naturally occurring chemical produced by every cell in the body. Alpha Lipoic Acid has been called the "metabolic antioxidant" by Dr. Lester Packer, considered one of the world's leading experts in antioxidant research. Even though Lipoic Acid is made naturally within the body there is good evidence that our bodies can lose the ability to synthesize enough Lipoic Acid when we need it most. Although the body produces small amounts of R-Lipoic Acid necessary for metabolism, this may not meet the needs of the body for free radical quenching. Supplementation may be beneficial and can produce profound therapeutic benefits.While Alpha R-Lipoic Acid acts as a potent antioxidant on its own, it also serves to regenerate other antioxidants like vitamin E, vitamin C and glutathione and also increases the production of glutathione (the most important water-soluble antioxidant).As the 'powerhouse' of cells, mitochondria produce the energy that cells need to function. As the cells age, the activity of the mitochondria decreases, resulting in lower energy production, slower metabolism and increased oxidative stress and damage. Clinical studies have also demonstrated that supplementation with Alpha R-Lipoic Acid improved mitochondrial function, increased metabolic rate and decreased oxidate damage.How Does R-Lipoic Acid Differ from Alpha Lipoic Acid?The 'R' form is the proper structural fit for membrane receptors (which allow for better "communication" with the cells) and enzymes, therefore, it is metabolized more efficiently and with much greater potency.Taking more synthetic ALA has not been shown to give the same benefit as R-Lipoic Acid.Alpha R-Lipoic Acid has been reported to be 10 times more powerful than standard Alpha RS-Lipoic Acid (ALA).

Features

  • Biologically active form of alpha lipoic acid
  • Better absorbed and more effective as an antioxidant than alpha-lipoic acid
  • R-lipoic acid by itself may be 10 times more effective than other forms of lipoic acid
  • Acts as a metabolic antioxidant
  • Powerful scavenger of dangerous free radicals

Description

BioAstin natural astaxanthin is the latest buzz among supplement and sports nutrition experts. First recognized for giving salmon and shrimp their red color, astaxanthin is now taking center stage in nutrition circles. A growing body of scientific research reveals that astaxanthin confers exceptionally powerful antioxidant protection to cells and has functional effects on muscle and nerve physiology. A clinical trial with BioAstin showed a significant difference in the onset of knee soreness in athletes performing intense leg exercises. The placebo group reported increased knee soreness, while the group taking BioAstin experienced no increase. A second human clinical trial with BioAstin indicated increased resistance to sunburn. Both trials used a four milligram dosage. BioAstin natural astaxanthin is a human dietary supplement with powerful antioxidant benefits. Cyanotech produces BioAstin from microalgae and it was the first source of astaxanthin for human nutrition that has been reviewed by the U.S. Food and Drug Administration (FDA). In August 1999, BioAstin completed a review by the FDA without objection and was allowed to be sold in the United States as a human dietary supplement. A growing body of scientific literature demonstrates that natural astaxanthin surpasses many of the antioxidant benefits of vitamin C, vitamin E, beta-carotene and other carotenoids. How is BioAstin produced? We have grown premium Hawaiian Spirulina for over 16 years at our 80 acre Kona, Hawaii facility. We produce BioAstin from another microalgae grown under rigorous quality control using our patent-pending closed culture system. This algae is used to seed fifteen 500,000 gallon systems. Each batch is analyzed and scrutinized for quality prior to being extracted in oil for the final product. The final product is HPLC standardized for guaranteed potency. Astaxanthin, the active component in BioAstin, appears to assist the muscle function by reducing free radical damage during heavy e
