7-Keto enables the body to build muscle in a growth promoting environment. It
has also been shown to increase your body 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 19501 (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 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, 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 wasnt until the mid 90 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 wasnt 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.
1. Safety of the product and the dose range proven to be safe.
2. Knowledge of how the supplement is taken up into the tissues and how quick
it is excreted, "in-essence it 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 optimise 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.
