Supports and promotes energy, vitality, stamina,
healthy mood and well-being*
A number of studies have been
conducted to assess the effect of supplementation with a less
concentrated fertilized egg powder (1.79g of the less
concentrated powder corresponds to 1.0g of YTE®) on libido and
sexual wellness. The causes for diminished libido are complex in
nature, and can be influenced by age, psychological factors and
other contributors. Although there is likely no single way to
support healthy libido in everyone, preliminary results on the
youthful stamina and libido enhancing effect of fertilized egg
powder are promising.
A preliminary study on 30 male rats
looked at the effects of fertilized egg powder on libido. The
rats were divided into three groups, and were given either
incubated fertilized egg powder, fertilized eggs with no
incubation, or placebo orally for three weeks. There was a
significant increase in several measurements of libido in the
fertilized egg powder group compared to the other groups, yet no
significant differences were observed between any of the groups
in testosterone levels.1
Open pilot studies on humans using
fertilized egg powder support its ability to promote
youthfulness and stamina. Several randomized double-blind
placebo controlled crossover human clinical studies measuring
enhancements in youthful libido have since been conducted. The
first was a small study on 16 middle-aged men that lasted 6
weeks. The men were randomly selected to take fertilized egg
powder for 3 weeks followed by 3 weeks of placebo or vice versa.
Libido levels were measured subjectively using a standard visual
analog scale. Those taking fertilized egg powder had significant
enhancement in libido compared to controls. This enhanced
effect diminished after discontinuing the treatment for 1 to 2
weeks. The second study lasted 12 weeks, and involved 31 healthy
men. They were randomized blindly for supplementation with
either placebo or fertilized egg powder, switching between
treatments every two weeks. As in the previous study, libido was
assessed using a visual analog scale. Although the enhancements
seen in this study were not as pronounced as the first study, a
statistically significant increase was seen during
supplementation with fertilized egg powder compared to the
placebo group. Over half the participants appeared to respond
positively to fertilized egg powder. Both studies indicate that
the beneficial results of supplementing with fertilized egg
powder become evident after 2-3 weeks of use, and appear to
decrease after 1-2 weeks of discontinuation of
supplementation.1,2 Moreover, the studies indicate general
trends for supportive benefits of supplementation with Young
Tissue Extract on youthfulness, vigor and stamina.
A
preliminary study of 11 human subjects taking fertilized egg
powder were asked to complete questionnaires which measured a
number of different aspects of healthfulness and youthfulness in
mood and other parameters of wellness. Subjects were given
fertilized egg powder as a supplement for three weeks, followed
by placebo for an additional three weeks. Questionnaires were
administered before supplementation, and then at weeks two,
three, five and six. General improvement was seen for all of the
qualities measured with statistically significant enhancements
specifically evident in six different measurements of
reproductive wellness, stamina and drive. Additionally, several
measurements of emotional well-being improved during the study,
including increased energy, confidence, and self-esteem during
the supplementation period. Several of the benefits occurred
during the supplementation phase and remained at the higher
level without further improvement during the placebo phase.
Other benefits remained evident even during the placebo phase.1
However, although subjects were blinded to the sequence of
receiving placebo vs. supplement, the outcomes are somewhat
difficult to evaluate as the study did not have a cross-over
design. Yet the results are still of interest and set the stage
for future studies.
A small preliminary study was conducted
to look at the effects of fertilized egg powder on muscle
strength and muscle mass. Thirty-two subjects consisting of both
genders took part in a 6-week study that looked at the effects
on skeletal muscle of supplementing with a combination of
fertilized egg powder and creatine compared to supplementation
with creatine alone. The results showed that there was a strong
trend toward improvement in muscle definition, muscle mass,
strength, training motivation, fat reduction, and increased
energy levels in the combination group containing fertilized egg
powder compared to creatine alone, although the results did not
reach statistical significance in this study.1
A further
small, unpublished cross-over study of nine advanced body
builders was conducted in which supplementation of fertilized
egg powder was compared to an isoenergetic control supplement.
The study design consisted of a washout period of 7 days before
the treatments were crossed over. In the group taking the
extract, an increase in cellular uptake of testosterone (as
determined by lowered blood testosterone levels), higher insulin
levels and lower cortisol (stress hormone) values were reported
after a workout as compared to the control
group.1
Safety
The supplement had excellent overall
tolerability, as there were no reports of any side effects in
the studies during supplementation with fertilized egg powder.
