Declining testosterone levels are all but inevitable as men age. After 40, men usually lose about 1% of their testosterone per year, and if they start out on the low end of the spectrum, symptoms related to low T can rear their ugly head early on.1 These include everything from poor sexual performance and fatigue to excess body weight and depression.2
Numerous products claim to stave off or reverse this declining testosterone, and several of them contain ingredients that research shows might make a real difference for most men. One of those supplements is Innerbody Testosterone Support.
Inside Innerbody Testosterone Support, you’ll find 11 ingredients, each of which has been shown either to increase testosterone production in men or to serve as a supportive ingredient to the other T-boosting components. In this review, we’ll take you through this product's pros, cons, and other details to help you decide if it’s right for you.
Our Findings
Innerbody Testosterone Support provides the best value among T-booster supplements by striking a scientifically sound balance between cost and dosage of multiple clinically supported testosterone-boosting ingredients. Only one or two competitors can compare for efficacy, but they’re significantly more expensive. There are men who ought to consider valuable but less expensive options — notably, Roman’s Testosterone Support and TestoPrime; for one thing, Innerbody doesn’t ship internationally, so men outside of the U.S. should consider TestoPrime instead. But for most men in the United States, Innerbody Testosterone Support is the best option for safely and effectively raising testosterone levels without aggressively depleting their finances.

Why you should trust us
At Innerbody Research, we thoroughly investigate every product or service we review, poring over scientific research, speaking with experts, and performing hands-on testing. Our evaluation of Innerbody’s Testosterone Support took a slightly different path, as we were involved in its creation from the ground up; we started with the foundation of research and built our supplement upon it.
We’d been covering the testosterone booster space for the better part of a decade, and we’d seen new supplements arrive on the market that showed promise but lacked one or two things that could allow us to recommend them wholeheartedly. Sometimes, they used a well-researched set of ingredients but didn’t provide them in doses that matched the ones used in successful studies. Other times, there’d be one or two well-researched ingredients delivered at clinically relevant doses alongside a handful of less credible ingredients without much, if any, clinical support.
Ultimately, this led us to the decision that we should create the supplement we wished were available. We’ll spend this review laying out the research and thought process that resulted in Innerbody Testosterone Support’s unique formula, but we strive to be honest in this process, and there are other testosterone boosters on the market that might be a better fit for you. Fortunately, we have a full guide dedicated to comparing them.
How we evaluated Innerbody Testosterone Support
We focused our scrutiny on several areas we consider to be top criteria for anyone interested in a supplement that boosts testosterone. These major factors include effectiveness, safety, cost, and convenience.
Let’s see how Innerbody Testosterone Support stacks up against its competitors in each area:
Effectiveness
We rate the effectiveness of any supplement — not just testosterone boosters — based on how its ingredients perform in clinical trials and how the doses in that supplement compare to the doses used in scientific research. If a supplement contains multiple, clinically relevant doses of ingredients shown to do what the supplement says it can, we have a much higher degree of confidence in it.
Of the 11 ingredients in Innerbody Testosterone Support, most boast studies that directly link them with testosterone support and male sexual wellness, while ingredients like copper and black pepper extract are present to offset a zinc side effect and increase nutrient absorption, respectively.
Among the ingredients directly linked to testosterone, the most important are ashwagandha, fenugreek, tongkat ali, zinc, and vitamin D. Innerbody’s ashwagandha, fenugreek, and tongkat ali doses meet or exceed doses in successful testosterone studies. Its zinc levels fall in the middle of the range seen in successful research, and its vitamin D levels are a hair below the average, the reasons for which we’ll explore in the safety section below.
First, let’s compare Innerbody’s doses to the dose range seen in successful research:
| Dose(s) used in successful testosterone studies | Innerbody Testosterone Support Dose | |
|---|---|---|
| Ashwagandha | 330-600mg | 600mg |
| Fenugreek | 180-600mg | 600mg |
| Tongkat Ali | 100-400mg | 400mg |
| Zinc | 10-240mg | 25mg |
| Vitamin D | 1,600-3,300IU | 1,000IU |
As you can see, the ingredients with the most promise for boosting testosterone are all present at doses that should provide significant efficacy. By comparison, a product like Roman’s Testosterone Support contains 600mg of ashwagandha and 30mg of zinc, but not fenugreek or tongkat ali and only 800IU of vitamin D. And while TestoPrime includes some ingredients Innerbody doesn’t, like pomegranate extract and D-aspartic acid, it only offers 200mg fenugreek and 55.67mg ashwagandha with no tongkat ali.
Safety
It’s one thing for ingredients to have high degrees of efficacy exhibited in human studies, but are those ingredients shown in studies to be safe at those same doses and concentrations? The primary drivers of Innerbody Testosterone Support that we discussed in the section above — namely, ashwagandha, fenugreek, tongkat ali, zinc, and vitamin D — all have low side effect risks. They aren’t without potential contraindications, but they’re mostly safe for most men.
The zinc and vitamin D levels in this supplement are less than what’s seen in several research papers and some competing supplements. The tolerable upper limits for zinc and vitamin D are 40mg and 4,000IU, respectively.3 4 For zinc, that number refers specifically to elemental zinc, of which Innerbody’s 25mg of zinc citrate provides 7.7mg. That allows plenty of space for dietary zinc and even zinc from a multivitamin to enter the picture without risking side effects or toxicity.
The same can be said of the 1,000IU of vitamin D. There are numerous variables to consider when calculating for vitamin D production from sunlight. Still, one study purports that an average of 38 minutes across skin tones and types, exposing only the hands, face, and arms, is enough to produce roughly 1,000 IU of vitamin D.5 So, a couple of hours outdoors and a few fortified foods might be enough to take you near a daily upper limit. Innerbody’s 1,000IU dose should provide a safe boost without going overboard.
Perhaps one of the most important inclusions from a safety perspective is the copper in Innerbody Testosterone Support. Roman is the only other company to include copper, but it’s a vital accompaniment to zinc. That’s because zinc supplementation has been shown to deplete copper levels.6 Adding a small amount of copper can offset this depletion.
Cost
Considering the ingredients and doses provided, it’s hard to argue that Innerbody Testosterone Support isn’t the best value on the market. However, it isn’t the least expensive testosterone booster out there, which is the strict focus of this criterion. In calculating a supplement’s cost, we take things like sticker price, subscription or bulk discount, and money-back guarantees into consideration. Innerbody gets high marks at every stop along the way, but there are still options you can find that may be effective for you and will cost you less money.
Here’s a quick comparison of potential costs at various savings levels between Innerbody and its top competitors — you’ll see why Roman remains our top recommendation for men on a very tight budget:
Innerbody Testosterone Support has a lowest possible cost per dose (taking into account bulk and subscription discounts) that outperforms Nugenix, Hunter, and GNC, but that’s a bit higher than prices from TestoPrime, Roman, or Testogen. And while its money-back guarantee is as good as or better than those from Roman, Nugenix, Hunter, and GNC, it’s shorter than guarantees from TestoPrime and Testogen.
Convenience
When we evaluate a nutritional supplement for convenience, we look at things like website quality (including ease of navigation and depth of information provided), order fulfillment, and customer service. We also consider things like dose regimen and capsule size, which can impact how easy it is to keep up with a daily supplement.
Innerbody’s Testosterone Support lives on a single, informative page that provides in-depth information on individual ingredients, including links to studies consulted during the formulation process. Ordering and fulfillment are fast and straightforward, as well, though these aspects of the process aren’t remarkable for the industry.
As far as the regimen and capsule size are concerned, Innerbody delivers its ingredients in four relatively standard-sized capsules, which is the most common dose in the sector. Roman, Testogen, TestoPrime, and GNC also use a 4-pill dose, and Hunter Test requires six pills per dose.
One inconvenience from Innerbody is that it currently doesn’t ship its Testosterone Support outside the U.S. International customers should instead consider a product like TestoPrime, which ships internationally.
What is Innerbody Testosterone Support?
Innerbody Testosterone Support is a nutritional supplement produced by Innerbody Labs, the product development wing of Innerbody Research. It comprises ingredients that have been studied for their potential to increase testosterone production and address symptoms of low T in men, as well as a few that are included to support those T-boosting components.
Here’s a quick look at Innerbody Testosterone Support’s ingredient list:
- Ashwagandha: 600mg KSM-66
- Fenugreek: 600mg
- Maca: 2,000mg
- Longjack: 400mg
- Vitamin A: 750mcg
- Vitamin D: 1000 IU
- Vitamin K2: 75mcg
- Zinc: 25mg
- Copper: 300mcg
- Selenium: 20mcg
- Black pepper extract: 5mg
Innerbody Testosterone Support is intended to be taken daily, and it should be able to elevate testosterone in a matter of weeks (as few as four weeks for some ingredients and up to 12 weeks for others).
What is low testosterone, and how do I know if I have it?
Low testosterone, or male hypogonadism, is a condition in which testosterone circulating in the blood falls below a certain threshold. The body needs testosterone for everything from regulating muscle protein synthesis and influencing body fat production to boosting immunity and managing stress.
If your testosterone numbers are below a certain level, your body might have less control over these processes, leading to increased body fat, decreased muscle and bone strength, irritability, depression, and a weakened immune system, to name just some of the symptoms.2 However, you can experience these symptoms for any number of reasons that have nothing to do with testosterone. The only way to know for sure if your testosterone levels are low is to take a test.
Clinically speaking, hypogonadism is defined by a test result of less than 300ng/dL, with a normal range running from 300-1,000ng/dL.7 But numerous things can influence a testosterone measurement, so urologists and endocrinologists typically require two test results before making a diagnosis, and they may not request a second test unless the first test indicates the potential for hypogonadism with a result of 400ng/dL or less.
Of course, if you’re dealing with severe symptoms that require immediate intervention, you may need to seek prescription testosterone replacement therapy (TRT) either through your doctor or a telehealth service. Fortunately, even in cases of clinically diagnosed hypogonadism, the ingredients in Innerbody Testosterone Support should be able to help men whose situations don’t require such drastic measures.
To understand each ingredient’s potential more fully, let’s look at how the supplement is designed to work.
How does Innerbody Testosterone Support work?
Innerbody Testosterone Support works by combining clinically relevant doses of various ingredients that studies show can improve testosterone production in men. Some of these ingredients have additional benefits that may help alleviate certain symptoms associated with hypogonadism in the short term, even as they work to bring T levels up in the long term.
For example, one ashwagandha study looking at its potential to alleviate stress saw a stress reduction greater than 17% after just four weeks.8 By comparison, many testosterone studies using ashwagandha see results after closer to 8-12 weeks. So, if low testosterone is causing mood effects, ashwagandha may be able to help with those even faster than it takes for it to begin recovering testosterone production.
Let’s take an even closer look at each ingredient Innerbody included in its Testosterone Support to understand what role they have to play.
Innerbody Testosterone Support ingredients
Innerbody Testosterone Support contains 11 ingredients, each of which is either capable of improving testosterone production or can support the action of the other, testosterone-related ingredients.
Here’s a thorough breakdown:
Ashwagandha offers a number of compelling benefits backed up by reliable research. For low testosterone, specifically, ashwagandha has been shown to increase free and total testosterone after eight weeks with a 600mg daily dose.9 That same dose was shown to alleviate stress at both four- and eight-week measurements in a separate study.8 Smaller doses have also been used in studies looking at strength and endurance, typically with positive outcomes.10
Innerbody employs 600mg of KSM-66 ashwagandha, a standardized extract containing at least 5% withanolides (the active component in ashwagandha credited for most of its benefits). KSM-66 is the most widely studied branded ashwagandha extract on the market.
Fenugreek resembles ashwagandha in its litany of potential benefits, from controlling blood sugar to increasing breast milk production. But its effects on male testosterone are especially powerful. One study using the same 600mg dose seen in Innerbody Testosterone Support saw free testosterone levels double in just eight weeks.11 Both the study dose and Innerbody’s dose are standardized to 50% saponins.
Some competitors utilize a branded fenugreek extract called Testofen, which is standardized to contain 50% saponins (the beneficial component of fenugreek, like withanolides in ashwagandha). Innerbody found an unbranded fenugreek extract with the same standardization and similar purity testing, providing the same potency at a lower cost to consumers.
In speaking to men interested in testosterone treatments, a recurring theme seems to be sexual performance, whether it be actual erectile health or just libido. The 2,000mg of maca extract in Innerbody Testosterone Support is here to support male sexual wellness more than it is to raise testosterone levels, giving men with low T an opportunity to experience better sex lives while the other ingredients build up in the system and begin to take effect.12
While studies haven’t shown a direct relationship between maca supplementation and testosterone levels, one recent study found significant improvements in self-reported Aging Male Symptom scores after just four weeks of use.13 That scoring system relates to many of the symptoms associated with hypogonadism, including low libido and poor erectile performance.
The 2,000mg of maca comes from 200mg of a potent 10:1 extract.
Also known as tongkat ali, longjack has, like ashwagandha, exhibited both pro-testosterone and anti-anxiety effects in scientific research. One study looking at serum testosterone and Aging Male Symptoms found that 200mg of longjack daily could eliminate Aging Male complaints and normalize testosterone levels in as little as one month.14
Another study using the same 200mg dose saw reductions in scores for tension, anger, and confusion, as well as a 15% drop in cortisol (the stress hormone) and a 37% increase in testosterone.15 Innerbody Testosterone Support deploys a 400mg dose, doubling what’s been shown effective in studies because doses up to 600mg have also been deemed both safe and effective.16
Numerous studies have tied serum testosterone levels with vitamin D levels in men. When one number is low, the other also tends to follow suit. This has been shown more as correlation than cause in either direction, but some research into supplementation suggests a direct link.
For example, one study looking at vitamin D supplementation’s effect on testosterone levels found that roughly 3,000IU daily could increase testosterone levels.17 Another used 50,000IU monthly (equal to 1,667IU daily) had similar results.18 These doses are admittedly higher than the dose found in Innerbody Testosterone Support, but Innerbody’s 1,000IU is less likely to put you at risk for adverse effects of vitamin D over-supplementation.
Like vitamin D, zinc has been indirectly tied to vitamin D levels in numerous studies over the years. Studies looking specifically at the effect of zinc supplementation on testosterone levels have seen increases in testosterone from 10.4mg and 15mg doses on the low end and up to 270mg doses on the high end.19 20 21
The tolerable upper intake limit for zinc is 40mg of elemental zinc.3 Innerbody uses 25mg of zinc citrate, which contains about 30% elemental zinc, or 7.7mg. That’s more than enough to be effective compared to the low end of studies and still safe enough to keep you from approaching the upper intake limit.
Copper is included in Innerbody’s formula not for any association with testosterone but as a safety measure against a known potential side effect of zinc supplementation. Studies have consistently shown that zinc supplementation can deplete the body’s copper levels.22 Adding a small amount of supplemental copper to the picture can offset this, ensuring that you reap the benefits of zinc without its potential drawbacks.
While vitamin A has been extensively studied in humans, research into its potential in testosterone production is limited to animal studies and in vitro analysis. Studies in rats have shown the recovery of testicular function after induced deficiency and increases in testosterone levels.23 24
Dose guidance for testosterone production is currently non-existent, but the daily recommended allowance of vitamin A for adult men is 900mcg. Here, Innerbody opts for a 750mcg dose, which ensures you come close to that, even if your diet doesn’t provide much vitamin A.25 And if it does, the tolerable upper intake limit is 3,000mcg, so there’s a safe amount of wiggle room here.
Just as copper is included here as an offset to zinc supplementation’s copper-depleting potential, K2 is included as a bulwark against vitamin D toxicity. As we discussed above, the tolerable upper intake limit for D is 4,000IU, which is easy to hit if you spend a couple of hours in the sun, eat fortified foods, and take a supplement. Supplementation with K2 can offset this potential for toxicity.26
Animal studies have looked into K2’s potential to increase testosterone levels with some success, as well, though at very high doses.27
Researchers have drawn a direct correlation between serum testosterone levels and selenium status in infertile men, illustrating that selenium is a key component in male fertility.28 If fertility issues are part of your concern over potentially low testosterone, supplementing with selenium should help.
Further research suggests that selenium deficiency can affect sperm motility, semen quality, and even newborn birth weight.29
Nutrient absorption is a key component of successful supplementation, and black pepper extract has been shown to increase nutrient absorption when taken alongside nutritional supplements of almost any ilk. One study using CoQ10 saw a 5mg dose of black pepper extract (identical to the dose in Innerbody Testosterone Support) increase absorption by around 30%.30
What about the ingredients Innerbody chose to leave out?
There are numerous other ingredients with the potential to boost testosterone that Innerbody excluded. Sometimes, there’s a clear data-based rationale for excluding them; either there was too little evidence to justify including an ingredient, or there was good evidence that it wouldn’t help (or could even hurt) your efforts.
In some other cases, there were ingredients with real potential to improve testosterone levels that would have been nice to see included here, but that would have driven the cost for consumers higher, especially considering the efficacy of the ingredients included in the present formula.
Here’s a quick look at what Innerbody chose to leave out:
While we have seen studies that show increases in testosterone levels as a response to exogenous D-aspartic acid, we’ve seen just as much evidence that it doesn’t work, including some research indicating a drop in testosterone levels above a certain dose.31 32 33 A systematic review concluded that, while evidence in animal studies was promising, evidence in human studies was inconsistent.34
Some research indicates that 10mg of boron daily can reduce the presence of sex hormone binding globulin, allowing for an increase in free testosterone.35 This is one of the most promising ingredients among those excluded from Innerbody Testosterone Support, but its daily upper intake limit is just 20mg, making a 10mg dose somewhat dangerous.36 Further research is needed into lower doses of boron.
Tesnor is a promising ingredient. It’s a branded combination of pomegranate peel and cocoa bean extracts. 400mg doses appear to significantly raise testosterone levels in study participants. However, the inclusion of this branded extract inevitably increases prices for consumers.37
Shilajit has the potential to improve numerous facets of male wellness, including testosterone levels. Research indicates that it may increase total and free testosterone, as well as DHEAS.38 However, most forms of shilajit are susceptible to heavy metal contamination due to their origin, and the safest form we know of is an expensive branded extract that, like other ingredients in this list, would raise prices too high for the benefits offered. On balance, excluding it here seems wise.
Ginseng is one of the more recognizable supplements out there. Unfortunately, there’s a deficiency of data regarding its use for testosterone support in humans. One human study on bodybuilders even found a reduction in testosterone levels in response to supplementation.39 A dearth of evidence combined with conflicts among a few available studies makes it clear why ginseng would be left out of Innerbody Testosterone Support.
Who is Innerbody Testosterone Support for?
Innerbody Testosterone Support is a strong option for men with low testosterone who want to recover normal T levels but don’t want to opt for prescription treatments. Any man dealing with hypogonadism would likely benefit from its ingredients.
Who should look elsewhere?
Even if a test result shows normal testosterone levels, these ingredients could help you with several symptoms that are associated with low T but don’t always stem from it. For instance, the ashwagandha and fenugreek doses can help alleviate stress and anxiety, and maca and tongkat ali can help address sexual wellness issues like low libido or poor erectile performance.
However, if your testosterone test results reveal a normal number, you could likely limit yourself to a straightforward ashwagandha or fenugreek supplement and spare yourself the more complex formula. Simpler supplements focused on those ingredients could save you money in that case.
Innerbody Testosterone Support isn’t intended for use by women; the supplement was formulated based on scientific research among men.
Customers outside of the United States should also seek a different supplement because Innerbody Labs does not ship internationally at this time. If you need a testosterone booster to ship internationally, we recommend TestoPrime.
Is Innerbody Testosterone Support safe?
Innerbody Testosterone Support should be safe for the vast majority of men who try it. Some ingredients have side effects worth considering, and there are certain potential contraindications with other medications or conditions we’ll go over. Still, the likelihood is that you can take Testosterone Support and expect few to no side effects, with the majority of those experiencing side effects encountering simple GI upset that should fade as your body gets used to the supplements.
Some of the botanical ingredients in Innerbody Testosterone Support are among the most likely to cause an issue for certain very small segments of the population. Here’s a quick look at their potential adverse effects:
Some researchers have theorized that tongkat ali may affect the DNA in the GI tract, though this conclusion is far more correlation than causation, and much more research is needed.40 What’s more, the doses used in this study were around 20g/day, compared to the 400mg/day in Innerbody Testosterone Support.
Fenugreek has been shown to be safe at doses reaching as high as 15g of a potent extract daily for 90 days. There is some risk of cross-reactivity for those with severe peanut allergies, however.41
Ashwagandha may influence thyroid hormone production in ways that could cause hyperthyroidism or thyrotoxicity in certain groups, including those on medication to control their thyroid function.42
Innerbody Testosterone Support pricing and subscription details
Innerbody offers discounts for subscribers, with the depth of savings increasing as those subscribers choose larger bulk purchases. One-time shoppers do not see discounts on bulk orders. Here’s how the pricing breaks down:
| Price | Cost per bottle | Cost per dose | |
|---|---|---|---|
| One-time purchase | $78 | $78 | $2.60 |
| Monthly subscription | $66 | $66 | $2.20 |
| Quarterly subscription | $164 | $55 | $1.83 |
| Semi-annual subscription | $357 | $47 | $1.57 |
Shipping from Innerbody Labs is always free, though it’s limited to the United States at this time. Every purchase is covered by a 30-day money-back guarantee, as well. That should be long enough to begin feeling the effects of certain ingredients, though some may take closer to 12 weeks to really kick in. Some competitors have longer guarantees, like the lifetime guarantee from TestoPrime or the 100-day guarantee from Testogen.
Alternatives to Innerbody Testosterone Support
Viable alternatives to Innerbody Testosterone Support exist, and you might find that one of these better suits your budget or your health needs, especially if you’re among the very few people who might not be a good candidate for one ingredient or another.
For example, TestoPrime has a slightly weaker overall ingredient bill relying heavily on a moderate dose of fenugreek and good doses of D-aspartic acid and zinc. But TestoPrime ships internationally, which Innerbody does not.
The best budget choice among effective testosterone boosters comes from Roman, whose Testosterone Support can be had for as little as $29 per month. That price gets you the same 600mg dose of ashwagandha found in Innerbody’s supplement, albeit one that’s not a branded or standardized extract.
Prescription testosterone therapy
If you’re suffering from significant hypogonadism or you and your doctor decide that you want to go further than a nutritional supplement might take you in restoring testosterone levels, you may consider prescription treatment. These therapies can come in the form of injections, topical creams, or simple capsules.
Our review of the available research leads us to believe that enclomiphene citrate offers the best balance of approaches for most men seeking prescription intervention.43 It’s a simple oral capsule, so there’s no need to worry about injecting yourself or accidentally spreading a medicated cream to anyone else who uses your bathroom.44
However, oral testosterone medications like these take some time to work, whereas testosterone replacement therapy in injections or creams is more or less immediate. Men who are significantly suffering under their hypogonadism symptoms may want to consider starting such a treatment to reset their levels quickly. However, due to some of the long-term safety concerns around TRT, we’d recommend transitioning to a safer, more manageable oral medication once your levels normalize.45
