Broccoli: a wealth of
phytochemicals
Broccoli may contain more
cancer-preventing nutrients than any other plant. In 1992,
scientists identified a broccoli compound called sulforaphane
that helps mobilize the body's natural cancer-fighting
resources and reduce the risk of developing cancer.27-33
Sulforaphane has been shown to
block the formation of tumors initiated by chemical
carcinogens. Moreover, sulforaphane has been demonstrated to
induce cancer cell death via apoptosis (natural cell death).33,34
A large amount of data shows that sulforaphane and other
broccoli compounds act as cancer chemopreventive agents by
favorably modifying carcinogen metabolism via modulation of
both Phase I and Phase II detoxification enzyme systems.35-39
This suggests that broccoli compounds prevent cancer by
activating detoxifying enzyme systems and inducing cancer cell
apoptosis.
Inhibiting DNA-adduct formation
reduces incidence of mammary tumors. Sulforaphane was shown in
one study to inhibit chemical-induced DNA adduct formation by
68% to 80%, suggesting that this broccoli extract may function
as a breast cancer preventive agent.37
On the basis of mechanisms of carcinogenic effects of
cigarette smoke, sulforaphane appears to be a component in the
prevention of lung cancer.
Broccoli contains the highest
percentage of D-glucarate of any plant studied, along with a
cornucopia of carotenes and other nutrients that provide a
wide range of health benefits. Life Extension Mix contains a
concentrated broccoli extract that is standardized to deliver
precise amounts of sulforaphane and D-glucarate in each dose.
Cancer-fighting flavonoids
Apigenin is a flavonoid found in
parsley, artichoke, basil, celery and other plants. A large
number of published studies have demonstrated the anticancer
properties of apigenin. Luteolin is a flavonoid found in many
of the same foods that contain apigenin. While luteolin
produces effects similar to apigenin, it has its own unique
beneficial properties as well.
When apigenin was tested against
other flavonoids on the growth of human breast cancer cells,
apigenin showed the most effective antiproliferative effects.40
Other studies show that apigenin or luteolin bind to estrogen
receptor sites on cell membranes in order to prevent
overproliferation of these cells.41
Apigenin and luteolin have been
tested against a wide range of different types of cancer, and
these flavonoids have consistently been shown to induce cancer
cells to differentiate into normal cells and undergo apoptosis
(programmed cell death). When measured against 27 citrus
flavonoids, luteolin had the most potent antiproliferative
activities against several tumor cell lines.42
Luteolin may help prevent breast
cancer. Several studies show that luteolin reduces excess
estrogen formation and blocks the binding of estrogens to
breast cell receptor sites.43,44
Life Extension Mix has the most concentrated bioflavonoid
complex ever put into a dietary supplement and includes
standardized extracts of luteolin and apigenin.
Enhancing
glucose metabolism
Glucose that is not absorbed by
cells is eventually converted into body fat. Aging cells lose
their ability to utilize insulin for the purpose of absorbing
glucose.45,46
This insulin-resistance is a direct cause of Type II diabetes,
obesity, atherosclerosis and a host of age-related diseases.
Some of the underlying
mechanisms required by cell membranes for youthful glucose
metabolism have been identified, and Life Extension Mix
contains well-documented nutrients to help break down
age-related insulin resistance.
Biotin is a B-complex vitamin that provides health benefits
ranging from the control of blood sugar levels to the improved
appearance of hair and nails.47-51
In order to improve glucose utilization in aging people, Life
Extension Mix contains a whopping 3000 mcg of biotin in each
daily dose.
Chromium has been shown to
improve peripheral insulin sensitivity, a parameter that is
unlikely to be directly influenced by biotin. Thus, the joint
administration of high doses of biotin and chromium is likely
to combat insulin resistance, enhance glucose uptake by both
liver and skeletal muscle and inhibit excessive hepatic
glucose production.52
There are 200 elemental micrograms of chromium in the daily
dose of Life Extension Mix.
Protecting
against mitochondrial aging
Massive free radical damage
occurs in the cells' energy power plants (the mitochondria),
which can overwhelm the cells' antioxidant defense systems.
Mitochondrial damage due to aging is a serious health problem
in elderly people, whose energy levels decline precipitously
even when they remain disease-free.53
The amino acid n-acetyl-cysteine has been shown to stimulate
glutathione production for the purpose of providing protection
against free radicals that are continuously being generated in
mitochondria.54,55
Free radical damage is both a
causative and contributing factor in the development of
degenerative disease. Scientists are now concentrating on
specific free radicals, the different part of the cell that
these free radicals attack and the types of antioxidants that
are needed to provide intra- and inter-cellular protection
against oxidative stress. Life Extension Mix provides
antioxidants, such as 600 mg of n-acetyl-cysteine and 500 mg
of taurine per daily dose, to protect against differing types
of free radicals both inside and outside of cells.56
Facilitating
youthful methylation
Enzymatic and genetic activity
throughout the body depends on the continuous re-methylation
of DNA. The age-related breakdown of youthful methylation
metabolism predisposes the body to a wide range of
degenerative diseases. Maintaining healthy methylation
patterns protects against DNA mutations that damage cells and
can cause cancer.
Vitamin B12 works
synergistically with folic acid and TMG to enhance DNA
methylation and reduce toxic homocysteine in the blood.
Scientific studies confirm that orally administered vitamin
B12 supplements are effectively absorbed by more than 99% of
humans.57
Vitamin B12 plays a critical role in many enzymatic processes
required to maintain good health. Elderly people can suffer
from severe neurological impairment if they are deficient in
vitamin B12.58
Life Extension Mix contains high
doses of folic acid and three different types of vitamin B12
along with a small amount of trimethylglycine (TMG).
Keep the blood
flowing
As people grow older, their
blood platelets become "sticky" and develop the propensity to
clot inside blood vessels. While conventional doctors accept
this as a normal consequence of aging, the scientific facts
are that the risks of stroke and heart attack could be reduced
dramatically by adhering to a program that inhibits abnormal
platelet aggregation. Life Extension Mix contains a variety of
nutrients such as ginger, grape-seed and bilberry that inhibit
platelet aggregation.
Dr. Linus Pauling's last great
work was to show that specific components in the blood called
apolipoproteins are involved in atherosclerosis and aortic
valve stenosis. Dr. Pauling showed that vitamin C and lysine
can protect against apolipoprotein-induced vascular disease.60
Life Extension Mix contains the amount of lysine (500 mg)
found in most lysine supplements. Those with valvular stenosis
or atherosclerosis may want to take additional lysine.
Magnesium deficiency is a prime
culprit in the epidemic of arterial disease that plagues the
Western world. Life Extension Foundation members have obtained
high doses of magnesium ever since Life Extension Mix was
introduced. Different forms of magnesium have shown other
beneficial effects at the cellular level in addition to
vascular protection.61,62
Life Extension Mix contains an advanced magnesium complex
consisting of magnesium arginate, magnesium taurinate and
magnesium glycinate to provide magnesium to different parts of
the cell.
Modulating
immune function
The immune system has been
extensively studied over the past 20 years, and scientists
have shown how specific nutrients can enhance components of
immune function decimated by normal aging.
Zinc and selenium supplements,
for instance, when given to elderly populations, significantly
reduce the incidence of infectious disease.63
One of the most important disease-preventing nutrients is
selenium. While too much selenium can be toxic, it appears
that most people take too little supplemental selenium out of
concern over toxicity. Life Extension Mix contains 200
elemental micrograms of three different types of selenium and
35 elemental milligrams of zinc from two different forms of
zinc to ensure maximum absorption.
Age-related autoimmunity can
create a state of chronic inflammation throughout the body.
New studies relate subclinical chronic inflammatory disease to
the development of senility, atherosclerosis, aortic valve
stenosis, some cancers and a host of other known inflammatory
diseases such as arthritis and colitis.64-67
Life Extension Mix contains nutrients that can be taken to
safely alleviate chronic inflammatory disease at the cellular
level.
Choosing a
multi-nutrient formula
There are a number of factors to
consider when deciding on a multi-nutrient formula that you
may be taking for the rest of your life. A significant concern
among vitamin consumers is the quality of the individual
ingredients that are contained in the formula. Life Extension
Mix contains only pharmaceutical-grade nutrient and herbal
extracts. Many commercial companies use food-grade components,
which may not provide the same therapeutic benefits.
Another factor to consider is
whether the potencies contained in a multi-nutrient formula
are adequate to provide the desired health benefit. The Life
Extension Foundation reviews thousands of published studies in
order to determine the ideal potencies of each vitamin,
mineral, amino acid and plant extract that is blended into the
Life Extension Mix formula. Most commercial multi-vitamin
preparations do not provide enough lutein, lycopene and other
expensive nutrients to produce a statistically significant
disease risk reduction effect.
In some cases, minor
modifications can mean a big difference in the benefit one
obtains from a multi-nutrient formula. For instance, most
people readily convert vitamin B6 to an enzymatically active
form the body needs called pyridoxal-5-phosphate. Some people,
however, do not convert vitamin B6, so Life Extension Mix
contains enough biologically available pyridoxal-5-phosphate
to ensure that no one taking this formula will suffer from a
vitamin B6 deficiency. The same is true with pantothenic acid.
While Life Extension Mix provides a huge dose of pantothenic
acid, it also provides a small amount of the more biologically
active pantothene.
The most important reason one
should choose a particular multi-nutrient formula is the
state-of-the-art ingredients it provides. Thousands of
published studies show that the risk of contracting cancer,
stroke, ocular disorders and heart disease can be reduced by
the proper intake of vitamins, minerals, amino acids and plant
extracts. The difficulty for most people is that they don't
know which nutrients are most important, or how much of each
nutrient to take. Commercial supplement companies have fallen
behind in keeping up with the breakthroughs in preventive
medicine appearing in the medical literature. Life Extension
Mix has been updated 15 times since its introduction in 1983
to provide the best disease-prevention nutrients known to
science.
Despite the fact that costly
pharmaceutical-grade nutrients are used in Life Extension Mix,
Life Extension Foundation members find that they save a
considerable amount of money compared to the cost of other
multi-nutrient formulas. Life Extension Mix provides more
potency for less money than commercial formulas, while
providing unique health-protecting extracts from plants.
The most
recently added ingredients
The most recent ingredient added
to Life Extension Mix has scientists so excited, that the
National Cancer Institute and U.S. Department of Agriculture
are spending millions of dollars to study its potential
effects.
As most health conscious
consumers are aware, a compelling body of evidence
substantiates the ability of selenium to prevent a wide
variety of diseases. Unlike most other supplements, selenium
comes in a range of biological forms that perform very
different functions in the body. The Life Extension Foundation
recognized this fact in the early 1980's and included several
forms of selenium in multi-nutrient formulas designed to
reduce disease risk.
Over the past year, a new form
of selenium has been identified that may be a highly effective
cancer preventive. In addition, this new form of selenium has
demonstrated unique properties that may someday result in it
being used as an adjuvant cancer cell killing therapy.
The name of this new selenium
compound is Se-Methylselenocysteine. We call it SMSC for
short. SMSC is the naturally occurring selenium found in
plants such as broccoli, garlic and onions. Like chlorophyllin,
SMSC has been shown to prevent DNA adduct formation that can
lead to the development of cancer.68
When compared to other forms of selenium, SMSC prevented
mammary cancer in rodents better than any other form of
selenium tested.69,70
SMSC has been shown to induce apoptosis (programmed cell
death) to cancer cells in culture.68,71-74
What makes SMSC different from
other forms of selenium is that it is not incorporated into
the body's proteins. Critics of selenium supplementation have
stated that the body cannot benefit from more than 55 mcg a
day of selenium because that amount saturates the body's
proteins. SMSC is not incorporated into any protein and is
therefore completely bioavailable for chemoprevention and the
synthesis of antioxidant enzymes such as glutathione
perioxidase.75,76
This new cancer-fighting form of
selenium has been added to Life Extension Mix. That means that
at no additional cost, Foundation members can obtain this
improved form of selenium (SMSC).
An increasing body of research
indicates that vitamin D3 has potent and unique cancer
preventing properties.77-79
In the past, scientists were overly cautious about
supplementation with vitamin D because of potential toxicity.
A recent study showed that even massive doses (as much as
10,000 IU a day) might be safe for some people. The potency of
vitamin D3 has been increased to 400 IU in the daily dose of
Life Extension Mix.
What is Life Extension Mix?
For the enlightenment of new
members, Life Extension Mix is a multi-ingredient composition
of extracts from vegetables, fruits, herbs and other food
concentrates that have been documented in published scientific
studies to prevent disease and slow premature aging. In
addition, Life Extension Mix provides pharmaceutical potencies
of the vitamins, minerals and amino acids that have
demonstrated significant health benefits. Most Foundation
members use Life Extension Mix as the cornerstone of their
overall program to attempt to live longer in optimal health.
Life Extension Mix has been
designed, tested and personally used by those who insist on
the strictest standards of pharmaceutical purity for every
nutrient included in the formula. Some people erroneously
refer to Life Extension Mix as a multi-vitamin supplement, but
a careful review of its ingredients shows that the formula is
light-years ahead of any other nutrient formula on the market.
Every ingredient in Life Extension Mix is based on scientific
findings about the role that specific nutrients play in
defending the body against degenerative disease.
New members are pleasantly
surprised when they discover that Life Extension Mix can
replace many of the individual supplements they were
previously taking. The convenience of obtaining potent doses
of pharmaceutical-grade nutrients is the prime motivation
for taking Life Extension Mix. Another reason that Life
Extension Mix is so popular is that it saves the serious
supplement user hundreds of dollars a year compared to the
cost of buying the ingredients in the formula on an
individual basis.
Life Extension Mix makes it
practical to follow a scientifically designed disease
prevention program. The Life Extension Mix formula has been
continuously improved over the past 20 years to provide
protection against newly identified mechanisms that have been
implicated in the development of degenerative disease.
