7-Keto DHEA
Lose Fat And Build Muscle!
7-Keto enables the body to build muscle in a growth promoting
environment. It has also been shown to increase your body's ability to
burn calories. It is a non-hormonal, non-androgenic derivative of
DHEA.
The groundbreaking new micronutrient 7-Keto, a patented compound
which, by activating thermogenic enzymes, has been shown to safely "rev
up" the basal metabolic rate and thus "burn" calories more rapidly and
continually throughout the day, even while resting, as well as inhibit
the storage of fat within the body.
All About 7-Keto
When we age the ability to control our quality of life becomes an
issue for all of us. The application of aging research into the steroid
dehydroepiandrosterone (DHEA) has helped our understanding of age
induced losses of functional capacity, and has subsequently lead to the
discovery of a relatively new compound "7-OXO-DHEA".
7 - Keto as it is more commercially known may have physiological
actions that allow us to train well into old age. Recent studies suggest
it may also have applications to a youthful, healthy, and physically
active population. So the questions beckon; is there evidence to support
7-keto use over a broad spectrum of ages? And if so, how can it affect
our physiques? And what lessons can be learned from ageing science to
keep us ahead of the dietary supplement market regarding the use of this
novel compound?
The Scientific Facts Behind 7-Keto DHEA
The appliance of science to any functional context, in this case your
health, performance and physique goals, are the mark of any good
nutritional scientist. But as a scientist you can only base your
assumptions on the scientific facts and fortunately for us this month we
have plenty to work with; as the discovery of the
DHEA
metabolite "3b -Acetoxyandrost
- 5 - ene-7, 17- dione" was discovered back in the late 1950's1
(and they wonder why we call it 7-Keto...imagine fitting that one on the
label).
Because of this we have amassed a large volume of work in this often
heavily chemical orientated, and sometimes confusing area of metabolism.
In the past, 7-keto's closest relative
DHEA
gave us the initial and
indeed pioneering insights into the potential benefits this class of
compound can deliver.
Although considered relatively inert by the mid to late 90's, this
view on
DHEA
was in for a radical change. The National Institute of
Aging (web site) issued a public
service announcement regarding its safety and warned consumers of its
sex steroid associated side effects5. Because of the
potential benefits to health, the search for a DHEA-like compound
without the associated side effects was on. Although first identified in
human urine in 19481 and tissues in 19546 it
wasn't until the mid 90's when Dr. Henry Lardy began the excellent
research on what he called "Ergosteroids"7.
The nomenclature of the ergosteroid family emerged due to their
influences on energy metabolism; indeed this area in particular will
form the core of our discussion on 7-keto. After a paper was released
showing that
DHEA
could bring about a thermoginetic effect in rats, it
wasn't long before both the nutraceutical and scientific world began the
search for an effective and "safe alternative to ephedrine" for fat
loss. In essence, a chemical that could confer the positive health
benefits of
DHEA.
Feeding The Machine (Pharmacokinetics & Safety)
DHEA
is a steroid produced by the adrenal gland7 and is
the most abundant steroid in human blood8. There are always
two things you should understand prior to the use of any sport / health
supplement.
- Safety of the product and the dose range proven to be safe.
- Knowledge of how the supplement is taken up into the tissues and
how quick it is excreted, "in-essence it's pharmacokinetic profile".
7-keto is a highly active derivative of
DHEA
and is one supplement of
which its pharmacokinetic profile is needed if we want to ascertain when
peak levels occur in plasma. This information will help prescribe the
best possible rational for its time of use, dosage, and safety to
optimize body compositional changes.
A series of trials have looked at both the safety and
pharmacokinetics of 7-keto (see Fig. 2 below.). In animal studies,
7-Keto was shown to be safe and in effect non-toxic to levels of
2000mg/kg in rats9 and 1000mg/kg in monkeys10.
Toxicity was assessed by full-blood chemistry, blood cell counts and
histological examination in 42 different tissues. Again caution must be
taken until we see the human data; so what human data does exist?
Davidson et al11 studied a series of doses ranging from
50mg/d (25mg twice daily) for 7 days; 100mg/d (50mg twice daily) for 7
days; and finally 200mg/d (100mg twice for 28 days). Results
demonstrated that at all doses, 7-keto in comparison to a placebo
presented no substantial impact on clinical blood markers of toxicity
and health. This data was supported in further human trials12-13.
