Truth Nutraceuticals Testro-X: An Evidence-Based Review

Testro-X is an all-natural Testosterone-Booster by Truth Nutraceuticals, the brand behind RedWood.  As Truth Nutra actually points out on the Testro-X page of the brand’s site, most “natural test-boosters” don’t actually work and are marketed in such a way that makes them seem as effective as steroids for building muscle.

We couldn’t agree more that most “Testosterone Boosters” are complete nonsense, but is Testro-X any different?  Let’s take a closer look…

Claims/Benefits

Truth Nutraceuticals claims Testro-X is their “premier natural Testosterone boosting supplement” which will increase Testosterone in both the short-term and long-term.

Needless to say, about a million other supplements have similar claims attached to them and, as it turns out, “natural Test-boosters” usually don’t work.

Before we rush to judgement though, let’s take a look at the ingredient profile of Testro-X to see if it’s really capable of making good on these claims…

Testro-X Ingredients

Testro-X contains 9 ingredients in total, two of which are Zinc and Magnesium (the basic components of ZMA), and three of which don’t appear to have any reasoning behind them…

ASHWAGANDHA (KSM-66)

Ashwagandha is an Adaptogen, meaning it helps the body adapt to stress (both physical and mental), but unlike many other so-called “Adaptogen” herbs, Ashwagandha has actaully been studied quite extensively for a variety of purposes.

In the context of Testro-X, Truth Nutraceuticals appears to be primarily concerned with the impact of Ashwagandha on the hormonal environment.

It has been shown to reduce Cortisol and promote an overall favorable hormonal environment.

In fact, in one study, Ashwagandha was shown to increase testosterone and muscle mass in healthy individuals (not experiencing sexual dysfunction), meaning it’s one of the few herbal supplements that can actually be considered a test-booster as opposed to simply a test-restoration supplement.

Check out this article if you’re interested in learning more about Ashwagandha.

Testro-X contains 400mg of KSM-66, a standardized form of Ashwagandha produced by Ixoreal Biomed which claims it is made using proprietary “green” extraction process which maintains the structural and functional integrity of the plant, unlike some other extraction processes which end of up destroying the active components (Withanolides).

The clinical range for Ashwagandha (KSM-66) is 300-600mg/day, so Testro-X actaully falls right in the middle of the clinical range.  Two servings daily will yield a highly effective dose of KSM-66, capable of restoring (and perhaps booosting) Testosterone.

Forskohlii Root Extract

Coleus Forskohlii, simply referred to as Forskohlii in this case, is an herb with an extensive history of use throughout various systems of traditional medicine for a variety of purposes.

In the modern world, it has been studied in the areas of weight-loss, cognitive enhancement, and hormonal health.

It’s active component, Forskolin, has been shown to increase Testosterone levels slightly when consumed at 50mg/day for several weeks, but Truth Nutraceuticals makes no mention of the Forskolin content of the Forskohlii extract used in Testro-X, so we can’t be sure how effecitve it is in this case.

Typically, Coleus Forskohlii extracts are standardized for 10 or 20% Forskolin, meaning 250mg would yield 25-50mg of active Forskolin.  If that’s the case with Testro-X, then it contains an effective (clinical) dose of Forskolin, but we just wish Truth Nutraceuticals would be a little more transparent label-wise.

Inositol

Inositol, sometimes referred to as Myo-Inositol (same thing), is a vitamin-like (not an actual vitamin) molecule that is structurally similar to Glucose.

It’s involved in a wide variety of bodily processes and has proven effective for treating anxiety, but there are virtually no studies which have investigated the impact of Inositol on Testosterone levels.

There may very well be health benefits to Inositol but, as for the reason it’s included in Testro-X, we have no clue.  It would appear that Truth Nutraceuticals is using it as a filler ingredient.  It’s cheap.  It’s known.  It looks good on the label.

But will it increase your Testosterone?  There is no evidence to suggest that it will.

Glycine

Glycine is very simple amino acid.  It’s mportant for, not only building muscle, but also for an endless array of bodily functions.  As a supplement, however, it’s not that useful unless you have trouble sleeping.

Unfortunately, there are no studies which have investigated the impact of Glycine on Testosterone levels, nor is there any theoretical mechanism by which it would.

It looks like Truth Nutraceuticals is using it as more of a “filler” ingredient than an active ingredient.  This is a common practice among some (shady) supplement companies because Glycine is dirt cheap, doesn’t have a strong taste (slightly sweet), and is recognized by many users of supplements.

In the context of Testro-X, Glycine is pretty useless though.

L-Theanine

Theanine is a unique non-dietary amino acid (found naturally in Green Tea) which has relaxation and anxiety-reducing properties but does not cause drowsiness in any way.

In fact, it has been shown to improve aspects of cognitive function and is a good addition to any supplement containing Caffeine.

That said, Testro-X does NOT contain Caffeine, nor is it meant to reduce stress, so we have absolutely no idea why Truth Nutraceuticals is using it here.

Theanine could potentially improve Testosterone status in highly stressed individuals by reducing stress hormones that negatively impact your body’s ability to produce Testosterone, but so can many other ingredients (including Ashwagandha), so again, we’re not sure what the reasoning is here.

Testro-X contains 100mg of Theanine per serving.

Boron

Boron is an essential trace mineral, the importance of which in human physiology has only recently been explored.

It has been shown to help with the retention of other minerals such as Calcium and Magnesium, but the real reason it’s used in Testro-X has to do with it’s impact on free Testosterone levels.

Multiple studies have confirmed that Boron supplementation (around 10-12mg/day) increases free Tesetosterone levels moderately in healthy human subjects.  The boost isn’t enough for Boron to help you pack on pounds of muscle, but it’s worth incorporating in any supplement designed to normalize/boost Testosterone levels.

Testro-X contains 10mg of Boron in the form of Boron Citrate (Boron bonded with Citric Acid), a highly bioavailable form of the mineral.  This is right around what can be considered a “clinical dose”.

Black Pepper Extact (BioPerine)

BioPerine is a patented form of Black Pepper Extract, standardized by the active component Piperine.  It has been used in TONS of supplements for the purpose of increasing the absorption of other ingredients and, at this point, enough studies have been conducted to conclude that it is indeed reliable.

Piperine has been shown to slow intestinal transport (allowing more time for nutrients to be absorbed) and may interact with certain enzymes throughout the digestive tract in such a way that maximizes absorption of other molecules.

It hasn’t been tested specifically with any of the other ingredients in Testro-X, but it certainly doesn’t hurt the formula at all either.

Testro-X Ingredient Takeaway

Testro-X contains a couple ingredients that may push Testosterone towards the higher end of the normal range, but it won’t boost your Testosterone levels to the point where muscle protein synthesis is accelerated and abnormal muscle growth occurs.

In a sense, it is the same as the “all-natural” Testosterone boosters that Truth Nutraceuticals condemns for dishonest marketing.  Ironic much?

Still, if you have abnormally low Testosterone levels–this happens as men get older (after 30 it’s pretty much down hill), Testro-X may help normalize Testosterone, so it’s not completely worthless.

We just don’t like the fact that it contains a few ingredients (especially Inositol and Glycine) that have no impact on Testosterone whatsoever and appear to just be “fillers”.  It would work just as well without them.  To us, that means they shouldn’t be included.  If it doesn’t help, it’s just a waste of money.

What About Zinc And Magnesium

If you’re familiar with Testosterone-boosting supplements in general, you’ve probably come across Zinc and Magnesium before, possibly in the form of ZMA.

ZMA is a suppplement (consisting of Zing, Magnesium, and Vitamin B6) which was first invented by Victor Conte of SNAC Systems (the guy primarily responsible for the BALCO Scandal of the early 2000’s.

Originally, ZMA was shown to increase Testosterone and muscle mass, but only in one study which was funded by SNAC Systems and conducted, in part, by Victor Conte himself.

Later studies revealed that ZMA doesn’t actaully increase Testosterone.  We discuss the whole thing in this article for those who are interested in learning the real truth about ZMA.

To make a long story short though, Zinc and Magnesium, while fulfilling a variety of important functions related to hormonal health, won’t elevate Testosterone levels unless you’re deficient.

if you are deficient, you could just buy Zinc and Magnesium separately.  They’re dirt cheap.  There’s no reason to over-pay!

In the context of Testro-X, these two minerals definitely don’t hurt, but how much they really help depends entirely on whether or not you’re deficient, so don’t feed into the hype.

Dosing

Truth Nutraceuticals recommends taking 1 serving of Testro-X (3 capsules) each day with food.  You could take two servings without worrying about any sort of side effects, but it’s not necessary because the ingredients that are effective are actually clinically dosed on a per serving basis.

Is Testro-X Safe?

Yes, Tesro-X is safe.  It contains nothing but all natural substances which can either be found in plants or are already abundant in the human body.  The question should really be “does it work?”…

Is Truth Nutraceuticals Telling The Truth?

Truth Nutraceuticals claims Testro-X contains “nine clinically supported and powerful all natural ingredients at their effective doses”, but actually…

Only a few of the ingredients have been shown to increase Testosterone and some of the doses remain questionable (How much Forskolin!?).

Where To Buy

If you really want to give Testro-X a shot, despite the fact that there are far better natural test-boosters out there, you’ll find it at:

You won’t find Truth Nutraceutical supplements at your neighborhood supplement retailer.  This appears to be a brand that is exclusive to the internet and mostly direct-to-consumer.

The Bottom Line

It’s possible that Testro-X will help improve Testosterone status in individuals with initially low Testosterone, but it’s important to understand the distinction between “boosting” Test and “restoring” Test.

KSM-66 is the only ingredient which has been shown to increase Testosterone AND muscle mass, but increased Testosterone isn’t necessarily the reason for the increase in muscle mass–it could just be training related.
