In our quest to build a lean, muscular body, we often look to a variety of sports supplements to help add a positive angle to our weight training programs. Whether it be protein powders, vitamins, or creatine, all things being equal, we all want to find that combination of supplements that will help unleash some of our muscle building potential.
The muscle building supplement industry is a multi million dollar industry that directly targets the active weight trainer as the buyers of these products. The list of muscle building supplements is a long one and it grows each and every week with no signs of slowing down. Today, there are literally hundreds of different brands and products with a variety of ingredients and mixtures.
These products are not only popular with the active weight trainer but also with the huge baby boomer market. To the active weight trainer looking to build lean muscle mass, this is an ideal situation.
We all know that testosterone is a male sex hormone whose primary role is the development of male reproductive organs. It also is responsible for the development of certain male characteristics such as increased bone mass, muscle mass, libido, deepening of the voice, and body hair growth among others. With an increase in testosterone, or more importantly, free testosterone levels, there is a higher chance of retaining those male enhancing characteristics of testosterone.
This can also mean a higher chance of increased muscle growth. It only makes sense that the more free testosterone we have in our body, the more lean muscle mass we can build, right? This is the key. Of course, not all natural testosterone boosters include the same ingredients.

Although some use a single source ingredient, most have a combination of active ingredients. When it comes to natural testosterone boosters, we need to ask one very important question. Does the product work when it comes to affecting overall body composition.
More specifically, does the product positively affect lean body tissues? All in all, most of these claims are unsubstantiated with little or no conclusive evidence to back up the claims.
First of all, do these products raise base levels of serum testosterone levels? If they do, the amount of increase is minimal at best. Thought to increase testosterone and strength levels, ZMA has NOT been shown to do either. Body composition was also measured in the test. At the completion of the study, there were no significant changes in either body composition or strength levels.

The results revealed increased levels of serum zinc levels but no increase in serum total or serum free testosterone levels.
A summary of the study can be viewed here. Tribulus terristris is a very popular ingredient among natural testosterone boosters and one you will find in most formulas. This a widely used supplement and has been very popular for quite some time.

Widely used in herbal medicine, tribulus terrestris has been used in traditional Chinese and Ayurveda medicine as a diuretic and aphrodisiac. The first group of rats acted as a control group while the remaining rats received the following dosages of tribulus terrestris extract: The results revealed an increase in body weight for each of the test groups in comparison to the control group.
There were no effects on strength levels or alterations in body mass composition after supplementation. The first group being the control group were given a placebo. At the end of the study, there was no significant differences in testosterone levels between the control groups and tribulus terrestris supplemented groups. All results were in the normal range. Based on the evidence, it seems that tribulus terrestris only works in the lab, and on rats.
Traditionally used as a herb and spice, it is used to help women improve milk production in lactating women and to reduce arthritis inflammation. Until recently, fenugreek has been picked up by some of the more popular supplement companies and included in their testosterone boosting formulas. Fenugreek had an overall positive effect on increased libido.
Body composition and strength levels were also measured in the study. The study also revealed an overall change in body composition but no change in strength levels. According to the study, there were changes in both lean body mass and an overall decrease in body fat percentage in comparison to the control group. An interesting study to say the least and something that needs to be investigated further.
I also looked at another experiment that studied the effects of fenugreek supplementation on fat consumption in overweight subjects. There are some correlations between the studies and may suggest some benefit to supplementing with Fenugreek. Native to Nigeria, Africa, fadogia agrestis has been used in herbal medicine to tread erectile dysfunction and to act as an aphrodisiac.
Although there have been no scientific evidence to substantiate any healing properties associated with this plant. This plant is used as a natural testosterone booster in certain formulas and has been claimed to greatly enhance testosterone levels. It was found that all the doses resulted in higher sexual behaviours as well as increased serum testosterone levels.
As for accredited human studies, none have been completed to date. In order to draw any type of conclusion, more independent clinical studies need to be completed on this plant. With that being said, there may be some potential for human trials to actually examine whether or not this supplement works. Will Brink over at www.politics-science-technology.org has issued a challenge to all supplement manufacturers to prove their testosterone boosters qualities and claims.
You can read about it here. This means muscle growth. In theory, urtica dioica inhibits the actions of the SHBG which promotes a larger portion of free testosterone to bind to a receptor cell.
It only makes sense that more binding testosterone will equal additional protein synthesis and muscle growth, right? However, there have been clinical studies that show the inhibiting effects of urtica dioica between SHBG and receptor cells on human prostatic membranes.
The study examined the effects that urtica dioica extract had on modulating the binding between SHBG and the receptor cell on prostatic membranes. Of the four extracts used, aqueous was the only active one.
Now, based on the theory and studies done on urtica dioica, is it safe to assume that it will help alter body composition in any way? There have been no clinical, human studies that suggest urtica dioica alters body composition in any way. Until this happens, you may want to wait to purchase any products containing this supplement. Boron is a chemical element that has been used in the past as a natural testosterone booster. It was actually pretty popular for a couple of years. It faded away into the supplement graveyard.
Boron was the first natural testosterone booster I ever tried. The gym owner where I trained actually swore by the stuff and recommended we try it. You have to remember, there was no creatine, nitric oxide, or any other of the modern supplements you see today.
At that time we basically had protein powders and vitamins – That was it. If you took something, you noticed if it worked or not. After our first month, we all gained strength. Now, I could have chalked it up to just about anything but at that time, if something worked, you knew. All I knew was that it was providing me with the results I desperately craved. Anyways, we had to wait a month or two before we could get our hands on a small bottle and after awhile, it was just too long a wait.
On the first day, subjects had blood collected and tested. Boron levels had increased significantly and six hours after supplementation, there was a significant decrease on sex hormone binding globulin.
After one week of boron supplementation, mean plasma testosterone levels increased while the mean plasma estradiol decreased significantly.
D showed a non significant, but higher level at weekly post supplementation period. You can view the findings of the study here. It was found that boron supplementation markedly increased serum levels of testosterone. Both of these studies have been completed on actual human test subjects in a controlled setting.
Each were independent studies that provided non bias results. There is actually a pretty cool website, written by Rob Thoburn about boron supplementation. According to his interactions with Reza Naghii, PhD, one of the researchers in the first study, boron does indeed raise serum testosterone levels.
But still I would recommend it to bodybuilders instead of steroids. It needs confirmation and deserves a research work among the bodybuilders. Limited results indicates its effect on increasing Vit d which requires hydroxylation for production and activation.
In my study in a weekwe found: an increase of Free T. It seems a shift from estradiol production into [the direction of] free testosterone, or higher androgenicity after one week.
However, there is currently no hard evidence that boron increases strength levels or alters body composition in any way. There are other herbs and plant extracts used in other formulas but to try and cover them all would be next to impossible.
The only one that comes anywhere near to any noticeable results is boron. Please keep in mind that this was not a controlled experiment and the results may or may not have been from boron.
All I can say was that something worked while I was taking this supplement. Unfortunately, this supplement has long been off the market so I can’t revisit and test this formulation. Of course, there is straight up boron available at health food stores and I may just try a couple of bottles out to see if there are any noticeable effects.
The research has provided evidence that this supplement does indeed improve serum testosterone levels in both, healthy males and elderly women. However, there has been no concrete evidence that boron improves strength levels or alters body composition Lean muscle tissue. The most important things you have to remember about natural testosterone boosters is that the product in question may increase serum testosterone levels, but at what point does it affect body composition and strength levels.
It’s one thing to ask if testosterone boosters help increase natural testosterone levels, but it’s another to ask if the additional testosterone actually binds to androgen receptors for additional protein synthesis Building muscle. Clearly, the evidence presented in most of the studies show a slight increase in serum testosterone levels but not enough to elicit any type of body composition response Building lean muscle tissue. Also, the dosage required in most testosterone boosting formulas is simply not enough to effectively raise testosterone levels.
However, there needs to be more detailed research on these supplements in order to draw any type of conclusion. For all you know, the study could have been done on rats. There is also the safety issue. Nobody really knows what the long term side effects are from taking natural testosterone boosters. Just keep this in mind, there has been no study completed to date that shows a natural testosterone booster significantly altering body composition Lean muscle tissue.
If you are dead set on trying a natural testosterone booster, please do a bit of research and decide which supplement, based on independent studies, are best for your situation. If you wish to have the product tested to see if it truly does increase T levels, I will be all too happy to have it tested for you. Be it, a true double-blind placebo crossover trial, which could also test whether or not the product in question will alter body composition in response to resistance training of courseor as a simple open label study.
So if there are any supplement companies who want to take Will up on his offer, just go to his website and talk with him directly. To top if off, I got absolutely www.politics-science-technology.orgg. Here’s a tip for those of you who want a testosterone booster that may help produce some results.
