Interesting! Schisandra never deprived me of sleep. A while ago, I stacked Schisandra, Reishi, Shilajit, Jiaogulan, and Fo-ti twice daily (morning and pre-bed) for a few weeks, and slept like a log!
strategic it's because most schisandra on the market is whole herb or extracted for Schisandrins...
First time a Schizandrin A has ever hit the bodybuilding market and I have yet to see one in the general market. Schisandra is dirt cheap but focus dirt is about 10x more expensive...
Our extract is schizandrin and more specifically Schizandrin A which produces the nootrophic effect...
treatment with
S. chinensis stimulated the activity of the CNS at night (activated excitation processes and
normalised nervous processes ratio), increased tonus of the sympathetic part of the autonomic
nervous system (having no effect on the parasympathetic part), activated the adrenal cortex
activity, increased the activity of the cardiovascular and respiratory systems, intensified
oxidation-reduction and metabolic processes, improved working ability parameters and, at the
same time, reduced parameters of non-specific resistance the organism and cellular structure
resistance and increased body temperature (Berdyshev, 1995).
S. chinensis, E.
senticosus and R. rosea (Rodelim) has also been shown to increase significantly the mental
working capacity of healthy volunteers when applied in repeated or single-dose format
(Vezirishvili et al., 1999; Roslyakova et al., 2000). The assessment was based on a study of
the psycho-emotional and psycho-physiological states, the professional and mental working
capacity, and the cardiovascular system of 60 computer operators on night duty under
conditions that simulated long monotonous activity inducing fatigue. The methods of
evaluation included mathematical analysis of the cardiac rhythm, computer tests,questionnaires and psycho-physiological tests, ophthalmologic examinations, and medical
tests (heart rate, ECG and respiration parameters, blood pressure, etc).
The effects of powdered seeds of S. chinensis on the mental working capacity of 59
students was studied (Lebedev, 1951a, b; Kochmareva, 1958) using a method of text
correction in which fatigue decreased the accuracy but not the speed of work. Following
treatment, the performance of 38 subjects (65%) improved, 17 showing an increase in the
number and quality of corrections made, 14 demonstrating an improvement only in quality of
correction, and 7 an increase only in the amount of work performed. Six constituents were
isolated from the seed material and the tests repeated on 20 subjects, every one of whom
received each of the compounds individually. Schizandrin (6) was found to be the most active
substance present in the seed material. A dose of 3.6 mg of 6 prevented exhaustion-relatederrors in text correction by the subjects: errors of the control group (treated with placebo)
amounted to 228% whilst those of the treated group were only 95% (errors in the control test
normalised to 100%) (Lebedev, 1951 a,b, 1967).
