AminoTherapy
by NutraBio represents a breakthrough in amino acid supplementation:
AminoTherapy amino acids contain absolutely no fillers, excipients, flavors,
sweeteners or additives of any kind, unless absolutely necessary. Just 100% pure active amino acids for
maximum bio-availability and optimized results. Other manufacturers, in an
effort to keep costs down, dilute their products with cheap fillers and add chemical excipients to increase their manufacturing output,
we don't! NutraBio's AminoTherapy amino acids
undergo state of the art analysis to insure zero tolerance for impurities.
Amino Acid
Ethyl Esters are amino acids
with an ester molecule attached. Esters are organic compounds that are formed by
esterification, which is the reaction of carboxylic acid and alcohols. Esters
help shuttle the amino acid across lipid membranes of
the gut and directly into the bloodstream for direct transport to your cells.
This prevents the amino acid from being destroyed in the gut and drives more of
the free form amino acid directly into muscle tissue where it can be more
efficiently used for its intended purpose. Whereas amino acid esters can pass
through the intestine largely intact, free form aminos can be significantly
degraded in the intestine, leaving only trace amounts of the ingested dose
active.

Esters are organic compounds that
are formed by esterification, which is the reaction of carboxylic acid and
alcohols.
Free form amino acids have inherent limitations such as limited absorption
through the intestine. Whereas amino acid esters can pass through the
intestine largely intact, free form aminos can be significantly degraded in
the intestine, leaving only trace amounts of the ingested dose active.
Because of the rapid breakdown of some amino acids in the intestine, its
beneficial effects can be limited. Ethyl ester amino acids are thought to
have a much better absorption rate and a longer half-life in the body than
regular free from amino acids because they are more lipophilic. Amino acid
ethyl esters are technically amino acids derivatives. Their ergogenic
effects are similar to those of their base free form amino acids, but the
presence of an ester can make the ergogenic effects more pronounced while reducing the need for
large doses, which may put less stress on the body. |
Amino acids are the building
blocks of protein in the body and are essential for the synthesis of
structural proteins, enzymes, some hormones and neurotransmitters. Amino
acids are also involved in numerous metabolic pathways that affect exercise
metabolism. Consequently, it has been suggested that athletes involved in
intense training require additional protein in the diet or that they should
supplement their diet with specific amino acids.
There are twenty amino acids
which are coded for DNA and therefore are used for protein synthesis. Of
these twenty, humans can only produce ten within their body. These ten are known as
non-essential amino acids since it is not essential that we get them through
food or supplementation because our bodies can produce them. The ten
essential amino acids that we can produce are alanine, asparagine, aspartic
acid, cysteine, glutamic acid, glutamine, glycine, proline, serine and
tyrosine. Tyrosine is produced from phenylalanine, so if the diet is
deficient in phenylalanine, tyrosine will be required as well.
The other ten must be
supplied in the food we eat or through supplementation. Failure to obtain
enough of even one of the ten essential amino acids can result in a
degradation of the body's proteins, (your muscle) to obtain the one amino
acid that is needed. Unlike fat and starch, the human body does not store
excess amino acids for later use so the amino acids must be in the food we
eat every day.
The essential amino acids are arginine, histidine, isoleucine, leucine,
lysine, methionine, phenylalanine, threonine, tryptophan, and valine. These
amino acids are required in the diet because the human body does not have
all the the enzymes required for the biosynthesis of all of the amino acids.
Below is a list of the
twenty amino acids that are coded by DNA for use in protein synthesis. There
are many other amino acids such as ornithine and GABA for example, that have
important uses in our body but are not used in protein synthesis. Creatine
is also considered an amino acid and is actually a combination of three amino acids -
Arginine, Glycine and Methionine.
