The terms yohimbine, yohimbine hydrochloride, and yohimbe bark extract are all related. Yohimbine is an active naturally found chemical (indole alkaloid) found in the bark of the Pausinystalia yohimbe tree. Yohimbine hydrochloride is a standardized form of yohimbine that is available as a prescription drug in the United States, and has been shown in human studies to be effective in the treatment of male impotence. Yohimbine hydrochloride has also been used for the treatment of sexual side effects caused by some antidepressants (SSRIs), female hyposexual disorder, and also acts as a blood pressure boosting agent in autonomic failure, xerostomia, and as a probe for noradrenergic activity.

After centuries of use in the Far East, medical doctors now report that Epimedium can be effectively used to boost libido, improve erectile function, restore sexual power and increase sensation. Scientifically, Epimedium works by freeing up testosterone, which naturally increases sex drive and endurance. It contains an active ingredient called Icariin, which acts as an aphrodisiac. Icariin helps to inhibit PDE-5 in the body, just as Viagra does.

Epimedium also increases blood flow to the male organs. It does this by allowing the nitric oxide levels to increase, relaxing smooth muscles. It also acts as a mild PDE-5 inhibitor like Viagra and reduces PDE-5 levels, at a level that doesn't produce unwanted side effects. (Unlike Viagra)

Ashwagandha is used as for sexual vitality, as an adaptogen, and as a sedative. Some refer to Ashwagandha as Indian ginseng, as it is used in ayurvedic medicine similar to how ginseng is used in traditional Chinese medicine. Ashwagandha is widely used in Ayurveda, an Indian system of holistic medicine. The root is primarily recognized for its adaptogenic properties. An adaptogen is a physiological agent with the ability to naturally increase the body's resistance to emotional and physical stresses. Ayurvedic practitioners traditionally use Ashwagandha to promote gentle relaxation and emotional balance. We included Ashwagandha Root in Lexaryn™ to act as a relaxing and stress reducing agent on the male's body to help erections form naturally.

Known as Peruvian Ginseng, which supports the glandular system. This herb serves two functions of sexual health: it enhances sexual performance and desire, as well as improves endurance and energy.

Lepidium meyenii or maca is an herbaceous biennial plant or annual plant (some sources say a perennial plant) native to the high Andes of Bolivia and Peru. It is grown for its fleshy hypocotyl (actually a fused hypocotyl and taproot), which is used as a root vegetable and a medicinal herb. Its Spanish and Quechua names include maca-maca, maino, ayak chichira, and ayak willku. Maca has been harvested and used by humans in the Andean Mountains for centuries. It was eaten by Inca warriors before battles, and was used a form of payment of Spanish imperial taxes.

A double-blind study by the Department of Urology, University of Ulsan College of Medicine attempted to study the "efficacy of Maca for erectile dysfunction." Their conclusion was, "Our data shows that red ginseng is an effective alternative for treating male erectile dysfunction".

A key ingredient of Maca is ginsenoside, which alters blood flow to the brain and penis and can build blood flow and sperm. Russian scientists have reported that Ginseng stimulates both physical and mental activity, enhances athletic performance and has a positive effect on the sex glands.

Used to combat impotence and premature ejaculation, Maca also helps normalize blood pressure while rejuvenating and revitalizing the body.

This is what scientists call the "Miracle Molecule" because it's powerful health-promoting properties make it THE most potent amino acid ever discovered. It lowers blood pressure, increases circulation of blood, and increases sperm count and semen volume in men. Its properties were recognized by the 1998 Nobel Prize in Medicine and since then it's created frenzy in natural medicine.

L-Arginine safely increases nitric oxide in the body. Nitric oxide causes vasodilatation, allowing for blood vessels in the penis dilate, increasing blood flow, and helping you maintain an erection. It stimulates protein synthesis and aids healing, bodybuilding, and the enhancement of sperm production.

Dimethylglycine (DMG) is a derivative of the amino acid glycine. It is found naturally in plant and animal cells and in certain foods such as beans, cereal grains, and liver. DMG is produced in cells during the metabolism of choline and is considered an antioxidant and enhancer of oxygenation at the cellular level. It has alleged use in enhancement of the immune system, stimulation of neurological functions, management of autism and epilepsy.

Studies have shown that DMG may help enhance immune responses and reduce stress. DMG helps to improve mental activity, produce high energy levels, and maintain immune system health. It also enhances oxygenation and organic functions. DMG is non toxic and no adverse effects have been reported.

L-tyrosine is an amino acid, one of the building blocks of protein. It plays an important role in the production of neurotransmitters that regulate emotions.

L-tyrosine is found in many protein containing foods, such as meats, dairy products, fish, wheat and oats. L-tyrosine benefits include helping the brain to produce adequate amounts of the neurotransmitters L-dopa, dopamine, norepinephrine, and epinephrine. All of these are necessary to regulate emotions. If levels of these neurotransmitters are insufficient, feelings of sadness, anxiety, irritability and frustration can result. In addition, dopamine helps suppress appetite and reduce body fat, so people with insufficient levels of this neurotransmitter may find they are gaining weight or struggling to lose it. Another way l-tyrosine benefits the body is by converting thyroid hormone to adrenaline during times of stress. Someone who is chronically stressed can have depleted levels of l- tyrosine. In addition to the need for sufficient amounts of amino acids to produce them, neurotransmitters can also become depleted by too much caffeine, sugar, or alcohol. Prescription drugs can also interfere with neurotransmitter production. In some cases, people find that a supplement of l-tyrosine benefits the body by providing the means to replenish neurotransmitters. Other l-tyrosine benefits include helping to calm the body, increase energy and enhance libido. It is also converted into the skin pigment melanin that protects the skin from harmful UV light rays.

L-tyrosine is thought to specifically affect several health conditions, particularly Parkinson's disease and certain mood disorders. Several studies have also indicated that l-tyrosine benefits people with Alzheimer's disease and dementia.

A member of the Vitamin B complex and classified as a lipotropic, or fat emulsifier, choline is helpful in strengthening the liver and also in assisting the treatment of cholesterol buildup, memory loss, and alzheimer's. How important is Choline? Deficiency of choline may contribute to liver degeneration and hardening of the arteries.

Choline helps to process fat and keep the heart and brain healthy. Choline is also needed for gallbladder and liver function, lecithin formation, hormone production, and regulate the central nervous system.

Choline makes acetylcholine, which is an important neurotransmitter needed for brain and memory function. In fact, scientists are now researching the possibility that choline may be beneficial in treating and even preventing diseases that affect the brain and central nervous system, such as Parkinson's disease and Alzheimer's.

In addition to its primary role of producing energy, NADH triggers many vital chemical reactions inside the cell. After much lab research and testing, scientists are very sure that NADH Acts as the driving force behind increasing energy production and increases energy while reducing fatigue. It also plays a key role in cell regulation with positive physical effects on blood pressure, cholesterol levels, sugar metabolism, heart rate and more. NADH is involved in DNA repair, and the repairs to worn out, wounded or damaged cells. Furthermore, studies show that NADH stimulates & increases the capacity of the immune system to produce antibodies and fight foreign invaders & disease.

By the way, it's the most potent biological antioxidant. Antioxidants in the body, such as beta carotene (a vitamin A precursor) vitamins C and D, and selenium -- prevent cell damage, and prevent a variety of diseases, like cancer. NADH also increases the synthesis of certain neurotransmitters in the brain - providing a positive physical effect on moods, memory retention, and learning and is effective in beating chemical based alcohol and drug addictions. Most importantly, it has been recently found that NADH corrects chemical imbalances involved in the physical causes of mental illness, anxiety, aggression, depression, erectile dysfunction, despair and hopelessness.

Tribulus terrestris is a plant that grows in tropical climates. The most interesting part of the plant lies in the root. This plant has been used around the world for a variety of ailments. It has been used as an herbal supplement diuretic, antiseptic, anti-inflammatory, and as a mood enhancing tonic.

The most noted benefits of tribulus terrestris is its use in treating sexual deficiencies. It has been used in Asia and Bulgaria for years to treat libido and infertility problems. Tribulus terrestris is a non-hormonal herb that restores and improves libido in men as well as improving and prolonging the duration of erections. Tribulus terrestris also increases sperm volume and velocity.

This is how it happens: Tribulus terrestris boosts testosterone levels by increasing luteininzing hormone (LH) levels. LH is the hormone that signals the body to start making natural testosterone. In a study involving individuals taking 750 mg per day of tribulus terrestris results showed that LH increased by 72%. Free testosterone went from increase by 41%. This increase in testosterone is the reason we included Tribulus Terrestris in Lexaryn™ .
