What is in Roaring Tiger MAX, how each ingredient has traditionally been used, and what research has looked at. We would rather tell you less and be accurate.
L‑Arginine and nitric oxide

Nitric oxide (NO) is a small gas molecule your body makes to send signals between cells. One of its jobs is telling the smooth muscle around blood vessels to relax, which lets blood flow more freely. The 1998 Nobel Prize in Physiology or Medicine went to Robert Furchgott, Louis Ignarro and Ferid Murad for discovering this role of nitric oxide in the cardiovascular system.
Your body makes nitric oxide from L‑arginine, an amino acid found in protein foods like meat, fish, dairy and nuts. An enzyme called nitric oxide synthase turns L‑arginine into nitric oxide and L‑citrulline. That is why L‑arginine shows up in so many men’s performance formulas: it is included to support healthy circulation.*
Horny goat weed (epimedium)

Horny goat weed is the common name for epimedium, a small leafy plant from Asia and the Mediterranean. In China it is called yin yang huo, and it has been part of traditional Chinese herbalism since at least 400 A.D., used as a tonic to support libido and vitality.* Legend has it the name came from a goat herder who noticed his flock grew livelier after grazing on it.
Its best-studied compound is icariin, a flavonoid. Laboratory and animal studies have looked at how icariin acts on blood vessels and hormones; research in people is still limited. MAX uses an extract standardized to 10% icariin.
Maca, tribulus and panax ginseng
Maca is a root vegetable grown above 13,000 feet in the Peruvian Andes. It has been eaten as food for centuries and is traditionally used to support energy, stamina and libido.* A few small human studies have looked at maca and sexual desire.
Tribulus terrestris is a flowering plant used in both Ayurveda and traditional Chinese herbalism. It became popular with Eastern European athletes in the 1970s and is now one of the most common herbs in men’s vitality formulas, used to support drive and desire.*
Panax ginseng, or Asian ginseng, is one of the most respected roots in traditional Chinese herbalism, where it is used as a tonic for energy and resilience.* Its active compounds are called ginsenosides.
Bioperine®: black pepper extract

Bioperine® is a patented extract of black pepper fruit standardized for piperine, the compound that gives pepper its bite. It has been studied for its effect on how well nutrients are absorbed, and MAX includes it to support absorption of the other ingredients.*
Bioperine® is a trademark of Sabinsa Corporation. More at bioperine.com.
The basics still matter

No supplement replaces the basics. Sleep, regular exercise, a healthy weight, less alcohol and not smoking all support healthy circulation and energy. If you have ongoing trouble with sexual function, talk to a doctor: it can be an early sign of a health problem worth catching, such as heart disease or diabetes.
