When you decide to buy a testosterone booster, you obviously feel the need to up your testosterone. Along with boosts in this manly hormone though, is an inevitable rise in estrogen. If this is left unregulated, it leads to a screwed up hormonal equilibrium and you really don’t want that.
Most testosterone boosters know this so they add natural ingredients that supposedly control this spike in estrogen. One of those ingredients is Damiana. However, there really isn’t much research that supports this claim. I did manage to find a few though so let’s get to the review and find out how they do.
WHY TEST BOOSTER SUPPLEMENTS USE DAMIANA
Damiana, also known as Turnera Diffusa, is part of the Passifloraceae family and is native to Mexico, Texas, and Carribean. It’s been used waaay before your grand dad was even born. Centuries ago, the ancient Mayans have already begun using Damiana as a sex enhancer. More recently, it’s been found as part of a testosterone boosting stack.
Like I said, Damiana is in testosterone boosters to regulate estrogen. This factor is typically more important in older men who’re more likely to have elevated levels of this female hormone. Testosterone supplements also seem to utilize the reported benefits of Damiana on sexual health. In the PCT scene where maintaining levels of testosterone, estrogen, and libido are of utmost importance, Damiana has also seen some time in the spot light.
Because it’s somewhat popular and has a rich history, I find it surprising that there isn’t much scientific research surrounding that health benefits of Damiana. Specifically for testosterone and estrogen, it has even less evidence under its arsenal. For what it’s worth, let’s check out some of the research below.
STUDIES ON DAMIANA SUGGEST:
Estrogenic activity and aromatase inhibition
A research was done to identify potential estrogen mimics or anti-estrogen phytochemicals. This study conducted docking two estrogen receptor isoforms (ERα and ERβ) to some of the most popular dietary supplements. To cut the long story short, they found 3 damiana compounds that strongly docked to the estrogen receptors.
Now, I know that doesn’t make much sense so let me add another research into the fray. This one was done to study the anti-aromatase and the estrogenic activity of constituents isolated from Turnera diffusa (Damiana). A methanolic extract of Damiana and the said constituents were then evaluated via different assays, which gave the researchers the following results:
- For Estrogenic activity
- apigenin 7-glucoside
- For aromatase inhibition
- Methanolic extract
See, the first study mentions to have found 3 Damiana compounds that strongly locked with estrogen receptors. The second study also showed 3 compounds with estrogenic activity. Combined, this gives me good reason to believe that the compounds they were talking about were one and the same.
No effect on testosterone
This next research examined the safety and efficacy of VigRX Plus (VXP) – a polyherb supplement that contains Damiana and other herbs used to improve male sexual function. The subjects in the study were grouped into either taking a placebo or VXP for 12 weeks. The ones in the VXP group received 2 capsules twice per day, for a total of 400 mg of Damiana. These are the results:
- Orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction significantly improved in the VXP group compared to placebo
- Serum Testosterone levels were not altered significantly in both groups
There are a couple of points I’d like to make about this study. First, VigiRX Plus isn’t plain Damiana. With it are 10 other herbs that are typically seen in men’s health supplements. Therefore, it’s impossible for me to gauge how much influence Damiana had on these results as nothing in the study points towards Damiana specifically.
Secondly, the main focus of the study was on male sexual function, not testosterone. They did include testosterone levels in their measurements but there isn’t really more detail. As such, take everything here with your own reservations because honestly, it’s not very reliable.
For what it’s worth though, Damiana, along with the other herbs used in this study doesn’t seem to play a major role (if any) in testosterone boosting.
Recover from sexual exhaustion
First of all, don’t lie. You get tired after ‘finishing’ the first round and can barely get it back up again for a quick second. Damiana has long been used for enhancing libido but according to the researchers of this next study, it hasn’t been studied for its ability to recover from sexual exhaustion so that’s why they did it.
In this research, sexually exhausted male rats were treated with Turnera diffusa at 20-80 mg/kg and yohimbine at 2 mg/kg. Trust me, the results are really fascinating. Check them out.
- With Damiana and Yohimbine, the percentage of achieving one ejaculatory series and resuming a second one significantly increased
- Damiana significantly reduced the post-ejaculatory interval
- No increase in locomotor activity or anxiety-like behaviors
There’s nothing in the study that points towards boosting testosterone (or regulating estrogen for that matter). It’s also a rat study, which of course isn’t very conclusive because we obviously aren’t rats. Still though, you have to admit that the results of the study are really, really interesting.
I mean, as a whole, the results of the research suggest that not only does Damiana grant the user with the power to go for that elusive round two, it also decreases the amount of time you have to recover after you’ve sprayed your man juice all over the bed (or a certain female body part if that’s your fetish).
But wait! There’s more! Word for word, the research says that “these effects were not associated to an increase in locomotor activity or anxiety-like behaviors“. You know what that tells me? It means you don’t think twice about going for another round. You just go ahead and do it. Score 1 for Damiana, 0 for sexual exhaustion.
How Do I Take DAMIANA?
As you can see, the research that surrounds Damiana show interesting results. However, these studies also aren’t very reliable with regards to testosterone boosting. As such, I also can’t give you a scientifically backed answer to this question.
In my time writing reviews though, I have noticed a trend in the way Damiana is dosed and it’s at around 400 – 2000 mg three times per day. That’s a maximum of 6000 mg for a single day. Thus, my suggestion is taking Damiana somewhere between that range too.
Sex is interesting and the research I’ve referenced to here are very interesting because they point towards Damiana’s potential benefits for sex. But honestly, although the results of the research caught my attention, they also aren’t very reliable.
One research shows Damiana having significant benefits towards libido but it was also taken as a part of an 11 ingredient stack. Another study also shows Damiana influencing manly virility and vitality by encouraging more rounds of sex but that research was done on animals (rats).
Another research also shows that Damiana had aromatase inhibiting compounds but these said compounds were also coupled with those that mimic the effects of estrogen by binding to estrogen receptors. Although this doesn’t necessarily mean that you get higher levels of estrogen, it suggests that Damiana may also come estrogen-like side effects.
To conclude, my personal opinion on Damiana is that it is not a reliable supplement for estrogen regulation but might have some benefit on sex and libido.
