Low energy, difficulty focusing, low sex drive, adding weight, struggling through a regular workout routine … all of these, or just a few of them can potentially be signals that testosterone levels are beginning to drop in your body. Testosterone is the male hormone that is directly associated with many male characteristics, such as strength, a deep voice, body hair, and much more.
As men age, the testosterone levels in their body begin to decline. This is a natural process of aging and there is very little that men can do to avoid it without adding certain supplemental nutrition to their daily diet.
There are numerous testosterone boosting supplements that have been introduced in the past 20 years that profess to be able to encourage the body to increase testosterone naturally. You can also choose an illegal form of testosterone boosting, which is commonly referred to as anabolic steroids. However, not only is this type of method illegal, it is extremely dangerous for many reasons.
If you are a man over the age of 25 and have begun to notice that you are feeling more fatigued, struggling to get through a workout, adding weight to your midsection, even though you are working out on a regular basis, or even experience a reduced libido, it might very well be directly related to the decreased testosterone production in your body.
Bulbine Natalensis is one of the many different types of supplements that are used to help promote an increase in testosterone production. The main focus is not just increasing the overall total testosterone levels in the body, but to increase the “free” testosterone levels.
Is Bulbine Natalensis Effective at Doing This?
Bulbine Natalensis comes from a natural herb that originally came from southeastern parts of Africa. It has a long history of being used as an aphrodisiac and for other medicinal purposes.
Commonly, you are going to find Bulbine Natalensis in a supplement called ProLensis™. There have been several studies conducted on Bulbine Natalensis, but most of them have been done on rats and only one official study has been done on humans.
The recommended dosage for Bulbine Natalensis for the average male weighing in at about 150 pounds is 500 mg per day. For a male weighing 200 pounds, the recommended dosage is 730 mg.
Let us take a look at three studies that had been found to determine whether Bulbine Natalensis is not only safe, but also effective at boosting testosterone levels in the body.
During this study conducted by Hofheins, Habowski, et al. through the Center for Applied Health Sciences in Stow, Ohio, they wanted to determine whether Bulbine Natalensis supplementation was safer for short-term usage within healthy males. They conducted a placebo-controlled, double-blind clinical trial consisting of 36 healthy men.
The men in the test group received four capsules of ProLensis™, consisting of 325 mg in the morning and 325 mg six hours later for a period of 28 days.
The researchers in this study did not measure whether Bulbine Natalensis was effective at boosting testosterone levels in any of the test or placebo male participants. They only studied to determine whether it is safe for consumption.
What they found was that it is as safe as a placebo within this study. They based their findings on hemodynamic, hepatic, renal, and hematologic biomarkers that they were assessing.

In the second study that we looked at, it was conducted by Yakuba amd Afolayan on Wistar rats through the Center for Phytomedicine Research, in the Department of Botany, at the University of Fort Hare in South Africa. This study was conducted in 2010 and wanted to look at the anabolic and androgenic activities of Bulbine Natalensis in these Wistar rats.
There were four groups that were studied, labeled Group A, Group B, Group C, and Group D. One group was the control group and consisted of 15 Wistar rats. The other groups also consisted of 15 Wistar rats each. The test groups were given 0.5 mL of distilled water for 14 days containing 25 mg per kilogram body weight, 50 milligrams per kilogram body weight, and 100 mg per kilogram body weight, respectively. What the researchers found was that testicular and serum testosterone concentrations increased in the groups B and C, but not in the group that received 100 mg per kilogram body weight, except after the first seven days.
Overall, the researchers concluded that the anabolic and androgenic activities of Bulbine Natalensis were most effective at 50 mg per kilogram body weight, based on the tests conducted.

Researchers Yakuba and Afolayan, the same researchers from Study #2, also conducted a test a year earlier on Wistar rats, but they were focused on reproductive toxicology evaluations with regard to Bulbine Natalensis. What they found was that testosterone levels reportedly increased 247% (1.6 to 5.2 ng/mL).
They determined that mating and fertility increased as a side effect of increased libido among the test subject rats.

While the overall research studies that have been conducted with regard to Bulbine Natalensis have been limited for human subjects, the findings that these studies report are positive with regard to boosting testosterone levels in male individuals.
It is important to note that the age of the human male participants was not listed in the research study for Study #1. More studies will need to be conducted on human male participants of varying age groups to determine whether exercise, age, or even other factors such as obesity have an impact on the effectiveness of Bulbine Natalensis.
I will continue to monitor any potential research studies that are published and will share the findings with you as soon as possible. Overall, it appears that Bulbine Natalensis is effective at boosting testosterone levels in the body in a safe and healthy way.
