Dosage
I've got a question regarding the dosage on tribulus terrestris
sex pill product. What
is the right tribulus terrestris dosage for long term use?
The dosage can vary between individuals
and at different times. The idea is to use it the least amount and dosage that
works. This could be as little as once or twice a week but no more than 4 times
a week. Tribulus terrestris dosage also depends on what other supplements or
medications a person is taking.
Athletic performance, and testosterone effect
Does tribulus terrestris have an influence on testosterone release or enhance
testosterone production? A human study done in Australia in 2007 did not find
TT to have a major influence on muscle mass growth, nor did
tribulus seem to influence blood testosterone levels in humans to any great
extent. Animal and human studies have shown conflicting results in regards to
the influence of tribulus terrestris supplements and testosterone levels.
Passion Rx with tribulus extract is even more potent.
Blood Sugar influence
[Hypoglycemic effect of saponin from Tribulus terrestris]
Zhong Yao Cai. 2002. School of Life Science, East China
Normal University, Shanghai.
To study the hypoglycemic effect of saponin from Tribulus terrestris L.
Alloxan was used to establish the diabetic model in mice. Phenformin
Hydrochlride Tables was used as the positive control. The level of glucose,
triglyceride, cholesterol and SOD in serum were determined. The level
of serum glucose could be significantly reduced by saponin from Tribulus
terrestris, which was the rate of 26.25% and 40.67% in normal mice and diabetic
mice in respectively. The level of serum triglyceride could be reduced 23.35%.
The saporin could also decrease the content of serum cholesterol. Serum SOD
activity of the mice was increased by the saponin. Saponin from
Tribulue terrestris could significantly reduce the level of serum glucose.
Hypertension
Study of antihypertensive mechanism of Tribulus terrestris in 2K1C hypertensive
rats: role of tissue ACE activity.
Life Sci. 2003. Department
of Pharmacology, Razi Institute for Drug Research and Cellular and Molecular
Research Center, School of Medicine, Iran University of Medical Sciences, Tehran, Iran.
Tribulus terrestris is a natural herb used for treating many diseases
including hypertension. According to previous reports, aqueous extract of
tribulus fruits may have some antihypertensive effect with an unknown mechanism.
The present study investigated the antihypertensive mechanism of tribulus in
2K1C hypertensive rats by measurement of circulatory and local ACE activity in
aorta, heart, kidney and lung. The ACE activity in all tissues of 2K1C
rats including: aorta, heart, kidney, lung as well as serum were significantly
increased compared to normal rats. The ACE activity in all tissues of tribulus
fed hypertensive rats was significantly lower than that of hypertensive rats,
which was more pronounced in kidney. These results indicated that there is a
negative correlation between consumption of tribulus terrestris and ACE activity
in serum and different tissues in 2K1C rats.
Kidney
Activity of certain fractions of Tribulus terrestris fruits against
experimentally induced urolithiasis in rats.
Indian J Exp Biol. 1994. Division of Pharmacology, Central Drug
Research Institute, Lucknow, India.
An ethanolic extract of the fruits of T. terrestris showed significant dose
dependent protection against uroliths induced by glass bead implantation in
albino rats. On subsequent fractionation of the ethanol extract, maximum
activity was localised in the 10% aqueous methanol fraction. It provided
significant protection against deposition of calculogenic material around the
glass bead. It also protected leucocytosis and elevation in serum urea levels.
Further, fractionation lead to decreased activity. This could be either due to
loss of active compounds during fractionation, or the antiurolithiatic activity
of T. terrestris being a combined effect of several constituents present in the
methanolic fraction.
Liver
Hepatic Effect of Tribulus extract
Tribulusamide A and B, new hepatoprotective lignanamides from the fruits of
Tribulus terrestris: indications of cytoprotective activity in murine hepatocyte
culture.
Planta Med. 1998. Research Institute for Wakan-Yaku
(Traditional Sino-Japanese Medicines), Toyama Medical and Pharmaceutical
University, Japan.
Tribulusamides A (1) and B (2), new lignanamides embracing two cinnamic amide
parts joined in a cis configuration, were isolated from the fruits of Tribulus
terrestris, together with four known compounds, N-trans-feruloyltyramine (3),
terrestriamide (4), N-trans-coumaroyltyramine (5), and beta-sitosterol. The
structures were elucidated by 2D-NMR spectroscopy. Addition of compounds 1-5,
especially 1 and 2, to primary cultured mouse hepatocytes significantly
prevented cell death induced by D-galactosamine (D-GalN)/tumor necrosis factor
alpha (TNF-alpha).
Oxalate
Effect of Tribulus terrestris on oxalate metabolism in rats.
J Ethnopharmacol. 1994. Department of Biochemistry, Panjab
University, Chandigarh, India.
This study concerns the effect of an aqueous extract of Tribulus
terrestris on the metabolism of oxalate in male rats fed sodium glycolate.
Glycolate feeding resulted in hyperoxaluria as well as increased
activities of oxalate synthesizing enzymes of the liver i.e. glycolate
oxidase (GAO), glycolate dehydrogenase (GAD) and lactate dehydrogenase (LDH),
and decreased kidney LDH activity. T. terrestris administration to sodium
glycolate fed rats produced a significant decrease in urinary oxalate
excretion, and a significant increase in urinary glyoxylate excretion, as
compared to sodium glycolate fed animals.
Thyroid function
Could you please tell me any
drug interaction with Synthroid (for hypothyroid) Effexor xr (depression &
anxiety.
There have not been any studies regarding the combination of tribulus terrestris and Synthroid or Effexor.
Small amounts could be fine, but higher amounts could cause side effects. If you
plan to use tribulus terrestris, start with a quarter of a capsule.
What's in the herb?
The fruits of
tribulus contain a number of different
substances including saponins, glycosides, flavonoids, alkaloids, resins, tannins, sugars,
sterols, and essential oil.
Recently, two new saponins have been isolated from tribulus
terrestris: Terrestrinins A and B, .
A frequently mentioned substance in
tribulus is
protodioscin, which some claim is one of the active substances within this plant. When
different samples of tribulus were analyzed, significant differences in the composition
of saponins
were observed depending on the origin and plant part used. One analysis of products showed
considerable variations of 0.17 to 6.5 % in protodioscin content.
How it works
T
extract may work by relaxing smooth muscles and increasing blood flow into the corpus
cavernosa. The relaxant effect observed is probably due to the increase in the release of
nitric oxide from the endothelium and nerve endings. Since tribulus relaxes smooth muscles, this
may account for its benefits in abdominal colic. It may also influence levels of
testosterone.
Side effects
No significant tribulus side effects have yet been reported in the medical
literature regarding the human use of tribulus terrestris. However, little is
known about the long-term use of tribulus consumption in humans. As with most
herbs, it is best to take breaks from use in order to minimize potential long
term tribulus side effects.
I have noticed and heard the following tribulus terrestris side effects: more
energy, feeling warmer, slightly faster heart beat, restlessness. These side effects are dose dependent.
Does tribulus have a side effect of blood pressure
increase? I have mild hypertension.
We have not seen human studies with tribulus supplements to know
for certain whether or not it influences blood pressure. You may consider at
first using half a capsule or a capsule every other day and monitor it. We have
not had any reports of high blood pressure side effect from the use of tribulus
supplements, but we can't be certain without knowing the results of scientific
studies.
Questions
Q. I have enjoyed reading Natural Sex Boosters, and have
been researching aphrodesiac herbs on the internet as well. I am unable to find
evidence for a stimulating effect on testosterone (or on LH ) attributable to tribulus terrestris Is there any supplement that will enhance the conversion of
androstenedione (endogenous) to testosterone ?
A. We have not seen enough human research on tribulus terrestris or
other aphrodisiac herbs to know what the short term and long term effects are on
testosterone secretion or production.
Q. I came across your website when looking for more
information on Tribulus Terrestris. This is because an extract of this plant is
being promoted for 'stimulating the Hypothalamus'. As I suffer from Narcolepsy,
for which the Hypothalamus is responsible, I wondered if Tribulus Terrestris
might help? I certainly don't need an aphrodisiac and don't know what effect an
increase in testosterone would have on me. Should I give Tribulus Terrestris a
try to see what effect it has on my narcolepsy? What should I look for in a
product in terms of ingredients?
A. There are countless herbs that influence alertness and could
keep a person awake, tribulus terrestris is not the only one. Ginseng, ginkgo,
acetylcarnitine, dmae, products such as Mind Power Rx and Eyesight Rx all help
alertness. It is difficult to predict which one or combinations will help any
individual person. We have not seen any specific studies in humans regarding
tribulus terrestris and narcolepsy or the long term influence of this herb on
the hypothalamic hormones.
Effect of Tribulus terrestris on nicotinamide adenine dinucleotide phosphate-diaphorase
activity and androgen receptors in rat brain.
J Ethnopharmacol. 2005. Department of Obstetrics and Gynaecology, National University Hospital, National University of Singapore, Singapore.
Tribulus terrestris L. (Zygophyllaceae) have been used as an aphrodisiac both in
the Indian and Chinese traditional systems of medicine. Administration of
Tribulus terrestris extract increased sexual behaviour and intracavernous
pressure both in normal and castrated rats and these effects were probably due
to the androgen increasing property of tribulus terrestris. The objective of the
present study is to evaluate the effect of Tribulus terrestrison nicotinamide
adenine dinucleotide phosphate-diaphorase (NADPH-d) activity and androgen
receptor (AR) immunoreactivity in rat brain. There was an increase in both NADPH-d
(67%) and AR immunoreactivity (58%) in Tribulus terrestris treated group and
these results were statistically significant compared to the control. Chronic
treatment of Tribulus terrestris in rats increases the NADPH-d positive neurons
and AR immunoreactivity in the PVN region. Androgens are known to increase both
AR and NADPH-d positive neurons either directly or by its conversion to
oestrogen. The mechanism for the observed increase in AR and NADPH-d positive
neurons in the present study is probably due to the androgen increasing property
of tribulus terrestris. The findings from the present study add further support
to the aphrodisiac claims of tribulus terrestris.
Q. I have a question about tribulus terrestris
product. I have read some studies that have shown many of these tribulus
products only produce a placebo effect unless they are made from the leaf of the
Tribulus terrestris plant. One study suggested that using 1500 mg/day, proved to
be successful for many functions. Could you tell me about the tribulus
terrestris product on your site and if it meets this criteria?
A. The tribulus terrestris product by Physician Formulas is an
extract of 40 percent saponins. It is potent. One capsule is just right for most
people and it may be a little too potent for those who are sensitive to herbs.
We don't suggest taking more than one capsule.
Q. Can tribulus terrestris lead to better
ejaculations?
A. Yes, some people notice better ejaculations with tribulus,
although tongkat ali works quite well, too.
I have just recently started taking 500 mg 2 times a day in the form of Tribex Gold 50-I am cycling 5 days
on-two days off. I have had erectile dysfunction fro about a year, with high
blood pressure, which is now normal with meds. Would it hurt to add Passion RX
to my regime? I am desperate to return to full erections.
We don't suggest using Passion Rx the same day as tribulus
terrestris.
For low testosterone problems, TT is reported to help. Can
the plant extract be taken at the same time with Passion Rx?
We suggest alternating their use every other day.
Im taking it as a part of my workout
supplements. I'm taking 1000 mg of it, is this safe for my liver and kidneys?, I
have heard that this plant is great for the liver and kidneys, I just wanted to
make sure.
Long term studies are not available to know the full benefits
and side effects. It is a good idea not to use it daily and to take breaks.
Q. I have seen a number of tribulus extract products on the market. How do I
know which extract concentration is best?
A. You are right that there are a number of different tribulus
extract potencies. Human studies have not been done comparing different extract
strengths to see which is best for erectile function. Your best option at this
time is to try different tribulus extract products to see which one works best
for you.
Q. i am a male 30 years old. i was treated for 5 weeks by
dompridone 10mg 3 times per day and nizatidine 150 mg twice daily ( as a
treatment of gastric reflux) after which i had a low or zero libido and a very
weak morning erection. Both drugs can cause hyper prolactinemia and anti
androgenic effect. I thought that it may be a hyperprolactinemia but it was not
i had a normal LH - PRL - Testosteron - Free Testosteron. Dompridone as a
dopaminergic blocker can cause low libido state and nizatidine h2 receptor
blocker has anti androgenic effect. i stopped these drugs one year ago but
believe me no improvement in morning erection and no improvement in libido at
all. i consult many andrologists and endocrinologists and no explanation now I
am on tribulus 250 mg cap 3 times daily. What is proper dose of tribulus
supplement.
A. Tribulus comes in varied extract concentrations, therefore not
knowing the actual extract potency is difficult for us to say. If it is plain
tribulus powder and not concentrated, a dose of 500 to 1000 mg a day is okay to
take, and it does not have to be tapered before stopping.
I am taking a drug called Bupropion HCL150 SA tab three
times a day and my concern was taking the Tribulus with it. Can you advise me of
any issues that might occur.
Much depends on the dosage of the medication used and the
dosage of the herbal product along with the unique response of the person using
them. As a general rule we suggest trying each supplement by itself for a few
days before combining, and then doing so with medical approval.
I would like to know if you have any research on a product
called Tribulus Aquaticus (stem and leaf, Its in a bodybuilding product from usp
labs called PRIME. Suposibly it does not raise testosterone levels like normal
Tribulus, the company claims that it works as a nutrient delivery agent of some
sort, I can say that my strength in the gym went up significantly from only
taking this product even more that when I took TT but I definitely feel as if my
test levels are elevated due to aggression.
We are not familiar with this product. A search on Meldine in
May 2010 did not reveal any studies with tribulus aquaticus.
