A couple of weeks ago I posted about the product ExtenZe,

a herbal nutritional supplement claiming to promote “natural male enhancement”, a euphemism for penis enlargement. Additionally, television commercials and advertisements claim an “improved” or “arousing” sexual experience [longer, stronger, harder erections]. (from Wikipedia)

Now another product has come along and is advertising heavily on cable tv, especially at night. Unlike ExtenZe, which contains small anounts of virtually every substance believed (in some tradition or another) to be of some efficacy in enlarging the penis or improving sexual performance, Nugenix has a small ingredients list, which includes one herb, fenugreek seed, that is not in ExtenZe.

From the Supplement Critique site, in a 9/13/12 review of Nugenix by Rob Miller (who rated it 4.5 out of 5):

Nugenix is a combination of zinc, vitamin B6, vitamin B12 and a testosterone booster complex that combines the properties of several herbal extracts.

Zinc is known to be a natural testosterone booster, as well, which means that there may be some truth to the manufacturer’s claims.

… the manufacturer [goes] through extensive detail about how the ingredients in their formula work, although it should be noted that most of their claims are not medically reviewed.

The Nugenix blend contains a compound called Testofen,which is actually a clinically studied ingredient that has been proven in lab studies to increase testosterone levels dramatically. Testofen is actually a patented version of the popular Fenugreek Extract, which is found primarily in the middle east and southern Europe.

Nugenix also contains L-citrulline, which is an amino acid, and Tribulus Terrestris, which is found in literally hundreds of other testosterone booster products, including Penatropin.

One thing that users may not like that much about Nugenix is that it must be taken daily in order to deliver effects. Three capsules per day is the recommended dosage and a free trial bottle has 42 capsules, giving you 14 days to try the product out. A standard bottle contains 90 capsules, and costs about $70 per bottle, making it quite expensive when compared to other natural testosterone boosters.


(On Tribulus terrestris, see the discussion in my ExtenZe posting.)

Note that Testofen — transparently a portmanteau of testosterone and fenugreek — is, like Nugenix, a registered name, but fenugreek is a pefectly ordinary common name for a well-known plant. From Wikipedia:

Fenugreek (… Trigonella foenum-graecum) is an annual plant in the family Fabaceae [the legumes], with leaves consisting of three small obovate to oblong leaflets. It is cultivated worldwide as a semiarid crop, and its seeds are a common ingredient in dishes from the Indian subcontinent.

Fenugreek is used as an herb (dried or fresh leaves), spice (seeds), and vegetable (fresh leaves, sprouts, and microgreens). Sotolon is the chemical responsible for fenugreek’s distinctive sweet smell. Cuboid-shaped, yellow- to amber-colored fenugreek seeds are frequently encountered in the cuisines of the Indian Subcontinent, used both whole and powdered in the preparation of pickles, vegetable dishes, daals, and spice mixes
