Branched-chain amino acids are
essential nutrients that the body
obtains from proteins found in food,
especially meat, dairy products, and
legumes. They include leucine,
isoleucine, and valine. “Branched-chain”
refers to the chemical structure of
these amino acids. People use
branched-chain amino acids for medicine.
Branched-chain amino acids are used to
treat amyotrophic lateral sclerosis (ALS,
Lou Gehrig's disease), brain conditions
due to liver disease (chronic hepatic
encephalopathy, latent hepatic
encephalopathy), a movement disorder
called tardive dyskinesia, a genetic
disease called McArdle's disease, a
disease called spinocerebellar
degeneration, and poor appetite in
elderly kidney failure patients and
cancer patients. Branched-chain amino
acids are also used to help slow muscle
wasting in people who are confined to
bed.
Some people use branched-chain amino
acids to prevent fatigue and improve
concentration.
Athletes use branched-chain amino acids
to improve exercise performance and
reduce protein and muscle breakdown
during intense exercise.
Healthcare providers give branched-chain
amino acids intravenously (by IV) for
sudden brain swelling due to liver
disease (acute hepatic encephalopathy)
and also when the body has been under
extreme stress, for example after
serious injury or widespread infection.
How does it work?
Branched-chain amino acids stimulate the
building of protein in muscle and
possibly reduce muscle breakdown.
Branched-chain amino acids seem to
prevent faulty message transmission in
the brain cells of people with advanced
liver disease, mania, tardive dyskinesia,
and anorexia.
A
branched-chain
amino acid (BCAA)
is an amino acid
having aliphatic
side-chains with
a branch (a
carbon atom
bound to more
than two other
carbon atoms).
Among the
proteinogenic
amino acids,
there are three
BCAAs: leucine,
isoleucine and
valine. The
BCAAs are among
the nine
essential amino
acids for
humans,
accounting for
35% of the
essential amino
acids in muscle
proteins and 40%
of the
preformed amino
acids required
by mammals.
BCAAs have been
used clinically
to aid in the
recovery of burn
victims. They
are also used in
the treatment in
some cases of
hepatic
encephalopathy.
A recent study
suggested that
the reduction in
blood BCAAs may
be associated
with improvement
in blood sugar
regulation. The
mechanism
remains unknown.
Another recent
study suggests
genetic
mutations in
some autism
models lead to
altered branched
chain amino acid
pathways that
might be
normalized with
dietary
supplementation.
Cota et al (1)
demonstrated in
2006 that
BCAAs,
particularly
leucine, also
affect the mTOR
pathway,
signaling two
regions of the
brain. These
signals decrease
food intake and
increase basic
metabolic rate.
These results
led to a
clinical trial
by Ordman (3) to
develop a
nutraceutical
method for
controlling
weight gain in
humans. The
potential of
nutrients to
signal changes
in metabolism is
exemplified by
how BCAAs may
increase muscle
repair, but
it is important
to be aware how
it may also
decrease
appetite.
Description/
Specification of
Branched Chain
Amino Acids
The three
essential amino
acids,
Isoluucine,
Leucine and
Valine are
collectively
known as
Branched Chain
Amino Acids
BCAA’s are used
by muscle fibers
during exercise
and promote
anabolic and
anti – catabolic
effects.The body
prefers to use
BCAAs during
periods of
exercise as a
source of
energy.
Effective
for: -
Improving muscle
control and
mental function
in people with
advanced liver
disease (latent
hepatic
encephalopathy). -
Reducing muscle
breakdown during
exercise. -
Decreasing
symptoms
associated with
mania. -
Reducing
movements
associated with
tardive
dyskinesia, a
disorder
associated with
the - use
of antipsychotic
medications. -
Reducing loss of
appetite and
improving
nutrition in
elderly patients
on hemodialysis.
BRANCHED-CHAIN
AMINO ACIDS
DOSING
The following
doses have been
studied in
scientific
research:
BY MOUTH:
For a brain
condition due to
liver disease
(hepatic
encephalopathy):
240 mg/kg/day up
to 25 grams of
branched-chain
amino acids.
For mania: a 60
gram
branched-chain
amino acid drink
containing
valine,
isoleucine, and
leucine in a
ratio of 3:3:4
every morning
for 7 days.
For tardive
dyskinesia: a
branched-chain
amino acid drink
containing
valine,
isoleucine, and
leucine at a
dose of 222
mg/kg taken
three times
daily for 3
weeks.
For anorexia and
improving
overall
nutrition in
elderly
malnourished
hemodialysis
patients:
granules of
branched-chain
amino acids
consisting of
valine, leucine,
and isoleucine
at a dose of
4 grams taken
three times
daily.
The estimated
average
requirement
(EAR) of
branched-chain
amino acids is
68 mg/kg/day (leucine
34 mg,
isoleucine 15
mg, valine 19
mg) for adults.
However, some
researchers
think earlier
testing methods
may have
underestimated
this requirement
and that the
requirement is
really about 144
mg/kg/day.
Other
researchers
think the EARs
for children are
also low. EARs
for
branched-chain
amino acids for
children are:
ages 7-12
months, 134
mg/kg/day; 1-3
years, 98
mg/kg/day; 4-8
years, 81
mg/kg/day; boys
9-13 years, 81
mg/kg/day; girls
9-13 years, 77
mg/kg/day; boys
14-18 years, 77
mg/kg/day; girls
14-18 years, 71
mg/kg/day.
INTRAVENOUS
(IV):
Healthcare
providers give
branched-chain
amino acids
intravenously
(by IV) for
brain
enlargement due
to liver disease
(hepatic
encephalopathy).
