Cialix is a male enhancement supplement that claims not only to increase testosterone but also to increase penis size. The brand is only sold online and is composed of "natural ingredients."
But does Cialix contain ingredients proven in medical research to be effective for increasing testosterone and sex drive? Is it possible for an oral supplement to increase penis size? And is Cialix likely to cause side effects?
In this article we'll answer all of these questions and more as we review the ingredients in Cialix based on medical studies to give our take on whether or not the supplement is likely to be effective.
We'll explain whether or not a dietary supplement can really increase penis size, give our take on whether Cialix is likely to cause side effects, and share our concerns about the brand generally.
The ingredients in Cialix male enhancement pills are shown above.
The supplement contains a proprietary (prop) blend with a total dosage of 1,489 mg. As we explained in our review of Alpha Brain ingredients, prop blends only publish the total dose rather than the individual dose of each ingredient, which makes it challenging to assess the safety and efficacy of a supplement.
Epimedium extract, more commonly known as horny goat weed, is the first-listed ingredient. This botanical compound was shown in animal studies to increase testosterone levels, but we can't find any human trials proving the same.
Eurycoma longfolia was shown in a 2017 medical review to improve symptoms of erectile dysfunction (ED).
Saw palmetto extract was shown in a clinical trial published in the Urology journal to improve erectile function in animals.
Bovine orchic susbtance is derived from the testicles of cows. We can't find any clinical evidence of its efficacy.
We are unable to source any medical studies suggesting the remaining active ingredients are effective for improving any aspect of male sexuality.
Cialix also fails to publish an inactive ingredients list, as you can see in the Supplement Facts label shown above. Inactive ingredients include capsule material, any fillers, preservatives or flavoring compounds. It's impossible to make an informed purchase decision without the full list of both active and inactive ingredients.
Overall, Cialix does contain some research-backed ingredients, but because the brand fails to publish the individual ingredient doses, we can't determine whether or not this supplement is likely to be effective for improving testosterone levels.
But can it increase penis size? We'll examine that claim in the next section.
Can a Supplement Increase Penis Size?
We find Cialix's health claim about increased penis size to be highly questionable. The brand fails to cite any research or provide any proof of this claim, and we haven't come across any medical studies suggesting that oral supplements can permanently increase penis size.
As we explained in our VigorNow review article on another supplement for penis size, it seems logically impossible for an oral supplement to alter the length and girth of the penis. The penis is an appendage, just like the fingers. There is no biological mechanism for its permanent growth beyond puberty.
Some supplements can increase the size of an erection by improving blood flow or arousal, but only to a maximum determined by the existing size of the penis.
Does Cialix Cause Side Effects?
Cialix doesn't appear to have been studied in any clinical trials, so it's impossible to say for certain whether or not the supplement is likely to cause side effects. However, we can make an educated guess based on its ingredients.
The active ingredients in Cialix are mostly safe and well-studied, however, the fact that the brand fails to publish the individual ingredient dosage increases the risk of side effects in our opinion.
Side effect risk is intractably tied to dosage. An active ingredient may not cause side effects at a dose of 200 milligrams (mg), but it may cause side effects at a 400 mg dose. Without knowing the individual ingredient doses, we can't establish whether or not those doses are in a safe range.
For this reason, we generally recommend avoiding supplements containing prop blends that aren't studied in clinical trials, because it's very challenging to assess their safety or risk of side effects.
