Whey Protein - Does It Really Work?
By: Bruce Brightman - LifeSource Vitamins
Whey protein (the highest
quality and best form of protein) is an amazing supplement. Whey Protein
provides the body with the necessary building blocks to produce amino acids
that are used for building muscle tissue. Nearly every bodybuilder knows the
importance of protein supplementation.
Studies have been conducted
that compare whey protein to numerous other sources. They have found that whey
protein contains the perfect combination of overall amino acid makeup... and in
just the right concentrations for optimal performance for the human body. Both
hormonal and cellular responses are greatly enhanced with supplementation of
whey protein. Not to mention the benefits whey protein has on the body's immune
system according to documented scientific research. Whey protein has also shown
to play a role as an antioxidant and helps support a health immune system. Most
importantly, consistent whey protein intake coupled with exercise will result
in consistent muscle building.
Whey protein is very
important for bodybuilders, dieters, and just about everybody! Since athletes
and bodybuilders work out often, protein levels become depleted. By being a
direct precursor to building muscle and essential amino acids, such as
glutamine (a muscle enhancer, endurance builder, and muscle deterioration
reducer), the content from high quality whey protein not only can, but will
help one's muscles recover and grow faster by bring up the levels of protein.
With dieting and those wishing to lose some extra fat, whey protein can be very
useful because a good intake of protein balances blood sugar levels, while
carbohydrates cause blood sugar levels to fluctuate. When the blood sugar
levels stay balanced, one is not as prone to rampant eating and has more energy
and greater fat loss. Whey protein allows a person to control his or her diet
effectively. Most people who want to change their body for the better could
benefit from whey protein supplementation.
Whey protein has become a
staple supplement for most bodybuilders and other athletes, and for good
reason: it's a great protein with a wide variety of benefits. Whey has more
recently caught on with the anti-aging/longevity-minded groups also.
A growing number of studies
has found whey may potentially reduce cancer rates, combat HIV, improve
immunity, reduce stress and lower cortisol, increase brain serotonin levels,
improve liver function in those suffering from certain forms of hepatitis,
reduce blood pressure, and improve performance, to name a few of its potential
medical- and sports-related applications. Whey also has an exceptionally high
biological value rating and an exceptionally high Branch Chain Amino Acid
One of whey's major effects
is its apparent ability to raise glutathione (GSH). The importance of GSH for
the proper function of the immune system cannot be overstated. GSH is arguably
the most important water-soluble antioxidant found in the body.
The concentration of
intracellular GSH is directly related to lymphocyte's (an important arm of the
immune system) reactivity to a challenge, which suggests intracellular GSH
levels are one way to modulate immune function. GSH is a tri-peptide made up of
the amino acids L-cysteine, L-glutamine and glycine. Of the three, cysteine is
the main source of the free sulfhydryl group of GSH and is a limiting factor in
the synthesis of GSH (though the effects of whey on GSH is more complicated
than simply its cysteine content).
Because GSH is known to be
essential to immunity, oxidative stress, and general well being, and because
reduced levels of GSH are associated with a long list of diseases, whey has a
place in anyone's nutrition program. Reduced GSH is also associated with over
training syndrome (OTS) in athletes, so whey may very well have an application
in preventing, or at least mitigating, OTS.
Pertaining directly to
athletes, some recent studies suggest whey may have direct effects on
performance and muscle mass, but this research is preliminary at best. Some
studies have found oxidative stress contributes to muscular fatigue, so having
higher GSH levels may allow you to train longer and harder, as some recent data
