· Reduces catabolism (muscle break down) after training and workouts.

Increasing Human Metabolism

· Improves white blood cell production.

· Restores the immune-promoting lymphoid tissue.

· Stimulates the proliferation of both B and T lymphocytes that help to kill viruses.

· Increases the uptake and degradation of dangerous LDL cholesterol by macrophages.

· Improves nitrogen retention (Muscle preservation) and increase sodium excretion.

· Improves parathyroid function vitamin D interaction to produce a dense bone matrix.

· Reduces the urinary hydroxyproline excretion.

Losing Fat

One of the major issues with losing weight and restricting calorie intake is the accompanying loss of muscle mass.  Lean muscle mass has been directly proven to stimulate an increased metabolism and fat loss.  Studies have shown that individuals receiving growth hormones lose 12% of their body fat every six months.  HGH increases the fat burning mechanism intrinsic to IGF-1, thereby not only preserving lean muscle mass but also increasing it.  IGF-1 also reduces cortisol levels and improves and regulates hormonal levels, which can be affected by calorie restricted diets.

Improving the preservation of lean muscle mass when fat loss is experienced would also benefit the health of an individual during weight loss procedures.  Studies have shown that the pituitary gland contains the same amount of growth hormone through an individual’s lifetime.  With age, however, the ability to release that growth hormone is somehow blocked in the feedback loop between IGF-1 in the liver and the hypothalamus of the brain.  Instead of reduced levels of IGF-1 signaling to the brain to direct the pituitary gland to make more growth hormone, this feedback loop is broken down with age.  It is for this reason why supplementing IGF-1 is not associated with negative feedback loops.

Slowing the Aging Process

In a study at the international Anti-Aging Systems in London, IGF-1 and HGH were isolated and administered to separate muscle tissues.  The IGF-1 injection had an anabolic effect on the muscle tissue, with marked increase in its size whereas the HGH administered muscle remained the same.  This study shows that HGH must be converted into IGF-1 before it can be metabolized by the body.

HGH is the primary hormone of the endocrine system.  As it pulsates out from the pituitary gland, it is quickly converted by the liver into IGF-1, the metabolite form of the hormone that is ready to use by the body.  Levels of HGH significantly decrease as humans get older, especially after the age of 40.  The decline in HGH is directly associated with certain aging signs like wrinkling skin, graying hair, decreased energy and sexual function, increased body fat, heart disease, and weak and brittle bones.  All of these symptoms of aging can be slowed down and even reversed with administering natural IGF-1 to counteract the biological aging process.

The International Anti-Aging Systems concluded that a mere 2,500 nanograms of IGF-1 taken sublingually is a therapeutic amount to help slow down the aging process.  In addition, research by Dr. Keith Kelly has shown that IGF-1 reverses the shrinking of the thymus, which is one of the most important immune modulation organs in the body.  This research shows exciting benefits of IGF-1 for those looking to halt and reverse the aging process.

Increasing Lifespan

IGF-1 has the potential to increase lifespan.  The blueprint of life that determines age is DNA.  Dr. Vincent Giampapa, Director of Clinical Research at the Longevity Institute International has studied how natural sources of IGF-1 may soon be able to turn old cells into new ones.  IGF-1 can help produce new healthy cells and keep them in a healthy state for as long as possible.  The cells ability to function relies on the genetic material of DNA.  This resides in the nucleus of the cell that codes for all proteins, hormones and enzymes that make the cell run.  Oxygen radicals and other factors such as UV light are constantly damaging DNA.  It has the ability to repair itself but this ability is dramatically reduced within the aging process.  Certain antioxidants can reduce the damage to DNA, but none have been shown to be as effective as IGF-1 in doing so.

European researchers have shown that IGF-1 is capable of doing what other antioxidants cannot.  IGF-1 initiates the transportation of nucleic acids into the nucleus of the cell where DNA resides.  It provides the raw materials necessary to repair damage to DNA and initiate cell division, helping to retard the aging process.

 
Are Amino Acid Supplements Useful? PDF Print E-mail

What are they?

The most popular amino acid supplement comprises the branched-chain amino acids (BCAAs):  valine, leucine and isoleucine.  These three amino acids make up one-third of muscle proteins.

What do they do?

The theory behind BCAA supplements is that they can help prevent the break down of muscle tissue during intense exercise.  They are converted into two other amino acids – glutamine and alanine – which are released in large quantities during intense aerobic exercise.  Also they can be used directly as fuel by the muscles, particularly when muscle glycogen is depleted.

What is the evidence?

Studies at the university of Guelph, Ontario, suggest that taking 4g BCAA supplements during and after exercise can reduce muscle breakdown (MacLean et al., 1994).  They may help preserve muscle in athletes on a low carbohydrate diet and, taken before resistance training, reduce delayed onset muscle soreness (Nosaka et al., 2006; Shimomura et al., 2006).  A study by researchers at Florida State University found that BCAA supplementation before and during prolonged endurance exercise reduced muscle damage.  However, similar benefits were obtained following consumption of a carbohydrate drink and it is not clear whether chronic BCAA supplementation benefits performance.

Do I need them?

They probably won’t improve your endurance but will help improve your recovery during hard training periods by reducing muscle protein breakdown and post exercise injuries.

 
Free Radicals Linked to Muscle Atrophy PDF Print E-mail

 

Muscle atrophy is a decrease in muscle size.  Lack of exercise, muscle and joint injury, surgery, extreme dieting and degenerative diseases cause muscle atrophy.  Bodybuilders experience atrophy when they are not training vigorously or when they are cutting for contests.  A review of literature by Scott Powers from the University of Florida and colleagues concluded that reactive oxygen species (ROS) – also known as free radicals – may cause muscle atrophy.  ROS causes cell damage and suppresses protein synthesis, which results in muscle atrophy.

 

Antioxidants in the mitochondria (powerhouses of the cell) protect against muscle atrophy.  At this point, we cannot identify specific supplements that can protect muscle cells from ROS and prevent muscle atrophy.

 

 
Free Radicals PDF Print E-mail

 

A free radical is an atom or group of atoms that contains at least one unpaired electron.  Electrons are negatively charged particles that usually occur in pairs, forming a chemically stable arrangement.  If an electron is unpaired, another atom or molecule can easily bond with it, causing a chemical reaction.  Because they join so readily with other compounds, free radicals can effect dramatic changes in the body, and they can cause a lot of oxidative damage.  Each free radical may exist for only a tiny fraction of a second, but the damage it leaves behind can be irreversible, particularly damage to the heart muscle cells, nerve cells, and certain immune system sensor cells.

Free radicals are normally present in the body in small numbers.  Oxygen-charged particles are created in the body as we breathe.  Diets rich in antioxidants can more than neutralize these particles. Dietary supplements rich in antioxidants act in the same way.  Biochemical processes naturally lead to the formation of free radicals, and under normal circumstances the body can keep them in check.  Indeed, not all free radicals are bad.  Free radicals produced by the immune system destroy viruses and bacteria.  Other free radicals are involved in producing vital hormones and activating enzymes that are needed for life.  We need free radicals to produce energy and various substances that the body requires.  If there is excessive free radical formation, however, damage to cells and tissues can occur.  The formation of a large number of free radicals stimulates the formation of more free radicals, leading to even more damage.

Many different factors can lead to an excess of free radicals.  Exposure to radiation, whether from the sun or small amounts from medical x-rays, activates the formation of free radicals, as does exposure to environmental pollutants such as tobacco smoke and automobile exhaust.  Diet also can contribute to the formation of free radicals.  When the body obtains nutrients through the diet, it utilizes oxygen and these nutrients to create energy.  In this oxidation process, oxygen molecules containing unpaired electrons are released.  These oxygen free radicals can cause damage to the body if produced in extremely large amounts.  Being overweight or consuming a diet that is high in fat can increase free radical activity because oxidation occurs more readily in fat molecules than it does in carbohydrate or protein molecules.  Cooking fats at high temperatures, particularly frying foods in oil, can produce large numbers of free radicals.

The presence of a dangerous number of free radicals can alter the way in which the cells code genetic material.  Changes in protein structure can occur as a result of errors in protein synthesis.  The body’s immune system may then see this altered protein as a foreign substance and try to destroy it.  The formation of mutated proteins can eventually damage the immune system and lead to leukemia and other types of cancer, as well as to many other diseases.

In addition to damaging genetic material, free radicals can destroy the protective cell membranes.  Calcium levels in the body may be upset as well.  Over time, the body produces more free radicals than it does scavengers.  The resulting imbalance contributes to the aging process.

Substances known as antioxidants neutralize free radicals by binding to their free electrons.  Antioxidants available in supplement form include the enzymes superoxide dismutase and glutathione peroxidase; vitamin A, beta-carotene, and vitamins C and E; the minerals selenium and zinc; and the hormone melatonin.  By destroying free radicals, antioxidants help to detoxify and protect the body.

 

 
The Ornithine-Arginine Connection PDF Print E-mail

Ornithine and arginine, two of the amino acids involved in the release of human growth hormone, are a dynamic duo and among the most popular amino acid supplements today, mainly because they can help you slim down and shape up while you sleep (which is when GH is secreted).  While some hormones encourage the body to store fat, growth hormone acts as a mobilizer of fat, helping you to not only look trimmer but have more energy as well.

Ornithine stimulates insulin secretion and helps insulin work as an anabolic (muscle building) hormone, which has increased its use among bodybuilders.  Taking extra ornithine will help increase the levels of arginine in your body.  (Actually, arginine is constructed from ornithine; ornithine is released from arginine in a continuing cyclic process.)

As a supplement, ornithine works best when taken at the same time and in the same manner as arginine (on an empty stomach, with juice or water, no protein).
