Tribulus is a natural, non-hormonal food supplement and is obtained from the medicinal plant tribulus terrestris. The medicinal plant, which grows in Hawaii, Eastern Europe, India and Africa, has been used to treat a number of various different diseases in these regions for centuries: muscular atrophy, reduced libido, impotency, infertility, edemas, liver complaints, renal diseases, heart problems and many others.
Studies have shown that upon intake of tribulus the body’s own testosterone levels rise by more than 50 percent. Tribulus is therefore called a testosterone booster. Contrary to DHEA and androstenedione, it raises the testosterone levels by stimulating the release of LH (luteinising hormone).
On account of its effects, tribulus is the best plant alternative to the synthetic – and mostly illegal – anabolic agents, as it comes closest to them in its effect. The only difference is that tribulus does not have any toxic side effects.
For athletes this means muscular growth and greater physical power as well as shorter recuperative times and convalescence periods after injuries. Together with the diuretic testosterone effect, this causes a well-defined muscular profile. Other positive effects of tribulus or the raised testosterone levels are increased general wellbeing and mood as well as a lowering of the cholesterol levels.
The active ingredients contained in tribulus are special secondary plant substances, the so-called saponines. The saponines (latin sapo = soap) are water-soluble natural glycosidic substances frequently occurring in plants. The main active ingredient is the substance protodioscine, a steroid-like compound. By stimulating the pituitary gland, tribulus causes the release of luteinising hormone (LH), which in turn speeds up testosterone production. The result is a raising of the free testosterone level in men and a raising of the progesterone level in women.
The traditional healing effect induced a medical research group at the chemical research institute in Sofia, Bulgaria, to subject tribulus terrestris to an intensive series of trials. A wide variety of different tests were carried out in humans and animals in the past 20 years, which proved that tribulus releases increased quantities (up to 72 percent) of the luteinising hormone (LH), thereby signaling the body to send more testosterone (up to 42 percent) into the blood stream.
The reason why the mechanism of action of tribulus is of great importance is that, in contrast to anabolic steroids, the body’s own testosterone production is not suppressed; on the contrary, more of the body’s own testosterone is produced. This is due to the fact that steroids inhibit LH release. Apart from LH and testosterone, tribulus also triggers the release of FSH (follicle stimulating hormone) and of estradiol.
The studies that have been carried out showed that tribulus stimulates myocardial activity, has an antibacterial effect, can be used against mycoses and inflammations, prevents the formation of kidney stones, supports the white and red blood cells and strengthens the immune system. Tribulus has also been used in angina pectoris (heart attacks) and showed a significant improvement of the complaints and symptoms.
Men: studies have proven that the daily intake of 750 – 1000 mg of tribulus demonstrably increased the testosterone level in men within 30 – 60 days at the latest.
In another test group the intake of daily 750 mg per day showed that after only 5 days the testosterone level had risen by 30 percent. At the same time, the participants experienced stronger libido, more stable erections and better spermatogenesis (formation of sperm). Most of the test persons also showed greater self-confidence and / or, in general, an improved emotional state.
Women: in female test persons tribulus caused an increase of the follicle stimulating hormone (FSH) and of estradiol. Frigidity was decreased, libido increased, fertility improved and climacteric complaints were reduced. Clear improvements were also found in the mental field (e. g.: less aggressivity, less dejection, more vitality).
Tribulus has proven to be an extremely effective way to increase energy and endurance during athletic activities. It acts directly and indirectly on the muscle fibers and also increases the testosterone level while – in contrast to anabolic steroids – it has no side effects of any kind and has proven to be totally safe.
Tribulus furthermore lowers high blood pressure, balances the sodium level, has a positive effect on the fluid balance of the tissue and makes the body less sensitive to pain. These are the reasons why tribulus has become an important food supplement for Olympic athletes.
One capsule contains 250 mg tribulus terrestris extract in pharmaceutical grade. Other ingredients: rice flour, magnesium stearate.
In normal cases take 1 – 3 capsules a day at mealtimes with plenty of fluid.
Tribulus did not show any kind of side effect in any of the studies that have been carried out.
Not suited for pregnant and lactating women. In general, be warned against self-medication, and especially persons who are under constant medical care should in any case consult a specialist before use. The same applies to the treatment of diseases with tribulus. Store in a cool, dry place and keep out of reach of children.
