Are there any side effects with taking Tribulus Terrestris?

Tribulus Terrestris is an herb which is also identified as the Puncture Vine or Caltrop also. It has various medicinal values but is most popularly used for its property to enhance sex drive in humans. A number of studies have been done on the Tribulus Terrestris herb and they conclude that if Tribulus herb is consumed in the correct amount then there is around 50 percent of increase in the testosterone levels.


Tribulus is being used by people from centuries and there has been a lot of research but nothing has found any negative side effects of Tribulus Terrestris. Upset stomach is one possible unpleasant side effect, which has been experienced by very few people and it can also be got rid of by having Tribulus Terrestris with food.


It is very important to use Tribulus as instructed. As a matter of fact despite being used by people of all cultures for last hundreds of years there have been no known side effects of Tribulus Terrestris. There is one key advantage of Tribulus that it is a natural extract and not a not a hormone. It assists in the augment of testosterone by increasing the level of Luteinizing Hormones in the body. LH on the other hand is responsible for invigorating the discharge of sex steroids in men and women both.


The important question which comes to our mind is should we use Tribulus Terrestris supplement? There is a very easy answer to this, yes as Tribulus Terrestris does not have a direct effect on your body and it is not a hormone. Tribulus extract has the ability to work in the natural perimeter of the body; it just assists your body in make the most of your muscles and also at other required areas. 750 to 1,250 mg of Tribulus Terrestris can be taken safely every day. It is best to take with meals to avoid any side effects of Tribulus Terrestris.


There have been no side effects of Tribulus Terrestris on the nervous or cardiovascular systems in the various clinical studies done on Tribulus Terrestris if it is taken in the right dosage. The only known side effects of Tribulus Terrestris exist when it is used as a dietary supplement as it has a very placid diuretic effect on the body.

Tribulus terrestris has no hormonal effects

The claims made by Tribulus terrestris supplements sellers are unfounded. Physiologists at the Universidade Federal do Parana in Brazil come to this conclusion in an animal study that will be published soon in the Journal of Ethnopharmacology. In experiments that they did, tribulus had no hormonal effects on rats.




In countries around the Mediterranean, herbal healers traditionally use extracts of the plant Tribulus terrestris as a remedy for infertility and impotence problems. Modern scientific studies have also confirmed the efficacy of tribulus for these complaints. In addition, however, the supplements industry started selling the same tribulus as a sports supplement, claiming that tribulus raises testosterone levels. One theory that supplements companies use to support their claims is that natural steroid compounds in tribulus are converted into DHEA or another testosterone prohormone.


The Brazilians decided to see whether this theory holds water. They gave the tribulus supplement Androsten, produced by the Brazilian supplements company Herbarium, to rats for a period of 28 days in doses of 11, 42 and 110 mg per kg bodyweight. The lowest dose is equivalent to the usual dose used by humans. Other groups of rats were given a daily 5 mg dose of DHEA per kg bodyweight, about ten times the amount that supplements companies advise humans to take, or 0.25 mg/kg testosterone propionate or 0.1 mg/kg ethinyl estradiol. The researchers administered all the hormones, dissolved in rapeseed oil, orally.


The tribulus extracts had no androgenic effect on castrated rats. The animals’ prostates did not grow as a result of being given tribulus. The testosterone propionate supplement, however, did have a growth-enhancing effect on the prostate.






When the researchers examined the faeces of the rats in the tribulus groups and compared them with those of the rats that had been given DHEA, they found that the faeces of the latter group contained more metabolites of male sex hormones. The faeces of the rats in the tribulus groups contained the same amounts of androgens as the faeces of the rats that had not had any supplements. So the theory that compounds in Tribulus terrestris are converted into DHEA or related steroid hormones does not hold water.


In female rats whose ovaries had been removed the tribulus extracts also had no hormonal effects, the Brazilians discovered when they compared cells from the uteruses of rats in the different groups.










A high dose of tribulus – but not the highest dose – did raise the testosterone level of the non-castrated rats, but the effect was not significant.










"Tribulus terrestris is not able to stimulate endocrine sensitive tissues such as the prostate, seminal vesicles, uterus and vagina in Wistar rats, indicating lack of androgenic and estrogenic activity in vivo", the researchers conclude. "We also showed an unchanged level of circulating androgens." The fertility of the rats was improved by the tribulus though.


It was already known that the manufacturers’ claims for tribulus supplements are not true. In 2008, doping hunters at the University of Lausanne in Switzerland reported that they had not been able to find any hormonal effects in tribulus users. Three years before, Bulgarian researchers had discovered that healthy men do not produce more testosterone as a result of taking Tribulus terrestris, [J Ethnopharmacol. 2005 Oct 3;101(1-3):319-23.] and five years before that, sports scientists at the University of Nebraska reported that power athletes had nothing to gain from taking tribulus. [Int J Sport Nutr Exerc Metab. 2000 Jun;10(2):208-15.]


A Tribulus variety that may have some effect is Tribulus alatus.

What side effects are caused by Tribulus Terrestris? What doses of Tribulus Terrestris should be taken?

What is Tribulus Terrestris?


Tribulus terrestris is a natural herb, commonly known as the puncture vine, that has been used for centuries in Europe as a treatment for impotence and as a stimulant to help enhance sexual drive and performance. On the athletic front, this potent herb has been studied and observed to enhance LH (luteinizing hormone) production and boost testosterone levels. This powerful extract, like DHEA and Androstenedione, can help elevate testosterone levels safely and its effects have been coveted by Bulgarian athletes for decades.


Why should I use Tribulus Terrestris?


Like DHEA and Androstenedione, Tribulus terrestris can naturally support testosterone production. Testosterone is vital because it plays many key roles in our bodies including building muscle size and strength. Athletes are using Tribulus terrestris to help ensure that their levels of this natural hormone are at normal levels at all times. This can thus ensure that testosterone levels are maintained through a natural platform without the use of dangerous drugs like steroids.


What research has been done on Tribulus Terrestris?


When scientists first started researching Tribulus terrestris, it was for the sole purpose of discovering a safe, natural treatment for sexual deficiencies. This research led to the discovery that Tribulus terrestris significantly elevated LH and testosterone levels. One follow-up study, conducted on healthy men ages 28-45, showed that 3 doses of 250mg taken evenly throughout the day for just five days elevated testosterone levels by 30% or more! Additional studies confirmed the previous study and also showed that, in addition to a rise in testosterone levels, subjects saw an increase in libido, frequency and strength of erections and recovery from sexual activity. Other changes that where noted included: a reduction of cholesterol, improved mood and increased self-confidence.


What doses of Tribulus Terrestris should be taken?


While there is no definitive guide on how much Tribulus terrestris should be taken, there are different guidelines suggested by experts in the medical field. Most suggest 250-750mg per day taken evenly throughout the day.


What side effects are caused by Tribulus Terrestris?


Just as with any supplement, caution should be exercised when considering taking Tribulus terrestris. In the research studies done, no adverse affects where noted from the use of Tribulus terrestris. In addition, further research demonstrated no adverse effects on the central nervous or cardiovascular systems. At this time no toxicity or negative effects presently exist when Tribulus terrestris is used as a nutritional supplement.


Should I cycle Tribulus Terrestris?


There is no evidence that shows conclusively what the optimal usage and duration of Tribulus terrestris should be. Many of the research studies done used 750mg of Tribulus terrestris for short periods of time. Unlike DHEA and Androstenedione, Tribulus terrestris is not manufactured by the body, however, prolonged usage could down-regulate it's effects and make it less potent and long term usage and its effects have not yet been studied, therefore cycling Tribulus terrestris might be advantageous.


There are different "schemes" of cycling that have been reported to work. These include a 3 week "on cycle" followed by a 1-3 week "off cycle", or a descending dosage pattern such as 4-6 weeks "on" followed by 3-6 weeks "off". As is the case with all supplementation, better judgment is the key to success. Knowing your body and its limits is as crucial to proper supplementation as it is to proper training.

The effects of Tribulus terrestris on body composition and exercise performance

Abstract
The purpose of this study was to determine the effects of the herbal preparation Tribulus terrestris (tribulus) on body composition and exercise performance in resistance-trained males. Fifteen subjects were randomly assigned to a placebo or tribulus (3.21 mg per kg body weight daily) group. Body weight, body composition, maximal strength, dietary intake, and mood states were determined before and after an 8-week exercise (periodized resistance training) and supplementation period. There were no changes in body weight, percentage fat, total body water, dietary intake, or mood states in either group. Muscle endurance (determined by the maximal number of repetitions at 100-200% of body weight) increased for the bench and leg press exercises in the placebo group (p <.05; bench press +/-28.4%, leg press +/-28.6%), while the tribulus group experienced an increase in leg press strength only (bench press +/-3.1%, not significant; leg press +/-28.6%, p <.05). Supplementation with tribulus does not enhance body composition or exercise performance in resistance-trained males.
