Supplement Facts
Tribulus Terrestris 400 mg per dose
(standardized to 40 % saponins)
Q. Can women take the Passion Rx, tribulis terrestri, tongat ali with food? Are they all in capsule form, so you can take part at a time? How do these taste? Can you mix in say V8 juice and not be repelled by the taste because I want to take a lower dose.
A. Passion Rx is potent so we don’t suggest taking it with tribulus or other herbs the same day. They are bitter but small amounts in a couple of ounces of V8 juice should be fine. They are in capsule form and the capsule can be opened by pulling on each side with a slight twisting motion. Taking it on an empty stomach may help absorption to be more complete.

Q. I would like to purchase bottles of Tribulus 40% Protodioscin. Below is from the bottom of Dr. Ray Sahelian’s page after going to Tribulus on the index. Forms Available: Tribulus Fruit extract 20% saponins, 40% Tribulus Saponins. Also available are 20% Protodioscin and 40% Protodioscin. Various misspellings include terrestis, tribulous, terrestrus, terristrus, tribulas. I was unable to find this product online. I am specifically wanting tribulus with protodioscin. 20% would be acceptable but 40% is what I would like.
A. We only have tribulus supplement with the 40 percent saponin version which works well. There are dozens of different tribulus extracts on the market and we carry one version

Research for libido, review of studies
One rodent study found tribulus to be helpful as a sex booster. Sexual behavior and intracavernous pressure (ICP) were studied in both normal and castrated rats to further understand the role of tribulus as an aphrodisiac. ICP refers to blood flow into the corpus cavernosa of the penis. Adult rats were divided into groups of 8 each that included distilled water treated (normal and castrated), testosterone treated (normal and castrated, 10 mg/kg body weight) and tribulus treated (castrated, 5 mg/kg body weight). Decreases in body weight, prostate weight and ICP were observed among the castrated groups of rats compared to the intact group. Compared to the castrated control, treatment of castrated rats (with either testosterone or tribulus extract) showed increase in prostate weight and ICP. There was also a mild to moderate improvement in sexual behavior as evidenced by an increase in mounting frequency.
Tribulus has been studied in China and found to reduce the frequency of angina pectoris. Laboratory studies have found tribulus to have anti-microbial and anti-tumor potential. I have not seen any good evidence that tribulus enhances athletic performance or has a significant effect on blood levels of testosterone. Tribulus may also lower blood levels of cholesterol, and, in addition, tribulus may also have antioxidant properties.
Tribulus, by itself, does not improve athletic performance.

Q. Does tribulus terrestres really work for sex? What about arginine.
A. Yes, tribulus terrestris does help with healthy erectile function, but for some people it may take a few days. We do not find arginine of benefit in ED treatment.

Tribulus as Aphrodisiac and Erectile Function, review
Aphrodisiac properties of Tribulus Terrestris extract Protodioscin in normal and castrated rats.
Life Sci. 2002. Department of Obstetrics and Gynaecology, National University Hospital, National University of Singapore, Singapore, Singapore.
Tribulus terrestris has long been used in the traditional Chinese and Indian systems of medicine for the treatment of various ailments and is popularly claimed to improve sexual functions in man. Sexual behaviour and intracavernous pressure (ICP) were studied in both normal and castrated rats to further understand the role of tribulus containing protodioscin (PTN) as an aphrodisiac. Adult rats were divided into five groups of 8 each that included distilled water treated (normal and castrated), testosterone treated (normal and castrated, 10 mg/kg body weight, subcutaneously, bi-weekly) and tribulus treated (castrated, 5 mg/kg body weight, orally once daily). Decreases in body weight, prostate weight and ICP were observed among the castrated groups of rats compared to the intact group. There was an overall reduction in the sexual behaviour parameters in the castrated groups of rats as reflected by decrease in mount and intromission frequencies (MF and IF) and increase in mount, intromission, ejaculation latencies (ML, IL, EL) as well as post-ejaculatory interval (PEI). Compared to the castrated control, treatment of castrated rats (with either testosterone or tribulus extract) showed increase in prostate weight and ICP that were statistically significant. It is concluded that tribulus extract appears to possess aphrodisiac activity probably due to androgen increasing property of tribulus (observed in our earlier study on primates).

Proerectile pharmacological effects of Tribulus terrestris extract on the rabbit corpus cavernosum.
Ann Acad Med Singapore. 2000. Department of Obstetrics Gynecology, National University Hospital, National University of Singapore, Singapore.
The objective of the present study was to investigate the effect of oral treatment of Tribulus extract on the isolated corpus cavernosal tissue of New Zealand white (NZW) rabbits and to determine the mechanism by which protodioscin (PTN), a constituent of the Tribulus extract, exerts its pharmacological effects. Twenty-four rabbits were randomly assigned to 4 experimental groups of 6 each. Group I served as control. Groups II to IV were treated with the extract at different dose levels, i.e. 2.5 mg/kg, 5 mg/kg and 10 mg/kg body weight, respectively. The Tribulus extract was administered orally, once daily, for a period of 8 weeks. The rabbits were then sacrificed and their penile tissue isolated to evaluate the responses to both contracting and relaxing pharmacological agents and electrical field stimulation (EFS). PTN on its own had no effect on the isolated corpus cavernosal strips. The relaxant responses to EFS, acetylcholine and nitroglycerin in noradrenaline precontracted tissues from treated groups showed an increase in relaxation of a concentration dependent nature compared to that of the tissues from control group. However, the contractile, anti-erectile response of corpus cavernosal tissue to noradrenaline and histamine showed no significant change between the treatment and the control groups. The relaxant responses to acetylcholine, nitroglycerin and EFS by more than 10%, 24% and 10% respectively compared to their control values and the lack of such effect on the contractile response to noradrenaline and histamine indicate that protodioscin has a proerectile activity. The enhanced relaxant effect observed is probably due to increase in the release of nitric oxide from the endothelium and nitrergic nerve endings, which may account for its claims as an aphrodisiac. However, further study is needed to clarify the precise mechanism of its action.

Energy increase and motivation
Q. Does this herb increase energy?
A. Yes, but repeated usage over several days and weeks is not advised. Tribulus herb works better for energy when used less frequently.

Athletics, gym workouts, physical endurance, bodybuilding
Q. Is tribulus terrestres a legal supplement to use by professional football players?
A. As far as we know, this supplement is legal to use in all professional sports.

Prostate gland enlargement, BPH
Q. Any reason to be concerned in using Tribulus terrrestres having BPH benigh prostate enlargement?
A. We have not seen any research regarding a connection between tribulus terrestris and prostate enlargement, but as with most supplements, we advise taking breaks from use and this minimize any potential problems.

Tribulus is most often found in combination with other sex-enhancing herbs. Tribulus is also sold by itself often in a dosage ranging from 250 to 750 mg. Tribulus is found in a variety of extract potencies.

Cautions and Side Effects
No side effects have yet been reported in the medical literature regarding the 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.

Mechanism of action
This herb 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.

What’s in Tribulus fruit?
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.

Tribulus review color and different brands and suppliers
You say your Tribulus terrestris 400 mg 40% saponins is an extract. I am under the impression the extract is red in color whereas your is green in color.
Tribulis herb is available from a number of manufacturers and we have noticed that the color is different from different makers, even different batches, but the 40 percent saponins can be consistent even with different colors. There are dozens of other substances within the herb that influence the color. Incorrect spellings include terestres extract tribulis terrestri supplement.
