Every Ingredient Earns Its Place.

Our formulas are built around one principle: every ingredient should have a clear purpose.

We select clinically studied ingredients, use doses aligned with published human research, and combine them thoughtfully to work with your body's natural biology. If an ingredient doesn't meet our standards for evidence, quality, or long-term safety, we leave it out.

See What We Included And Why

Ashwagandha Extract600 mg

Improve testosterone and VO2Max while reducing anxiety*

In clinical trials, ashwagandha increases testosterone in men while profoundly reducing stress and anxiety. KSM-66® is especially potent, with a high concentration of the botanical’s active compounds. We include 600mg because compelling clinical research has shown the effectiveness of KSM-66® using that specific dose. In just two months, studies demonstrate that it can:

Vitamin A750 mcg

Improve testicular function*

Vitamin A was central to a decades-long study examining how lifestyle and nutrition can influence testosterone levels. It’s abundant in foods, but we still included nearly 85% of your daily value to ensure that it can:

Vitamin D325 mcg

Increase strength, power, and testosterone levels*

Multiple studies have not only drawn a direct correlation between low vitamin D levels and low testosterone, but also revealed that supplementing improves both vitamin D and testosterone levels. The 1,000 IU we provide here has been shown to:

Vitamin K275 mcg

Support testosterone production at the genetic level*

While some ingredients influence the testes or Leydig cells toward increasing testosterone, it appears that K2 holds sway over your very genes, pushing them toward better testosterone production. Our 75mcg dose can:

Zinc25 mg

Boost immunity, sperm health, and T levels*

Research dating back decades shows an undeniable link between zinc and testosterone, as well as other vital health stats. With nearly 1 in 10 men in the U.S. at risk for a zinc deficiency, our 25mg dose helps safeguard your healthy zinc levels. Studies show it can:

Selenium20 mcg

Support fertility and sperm morphology*

A critical trace mineral, selenium is integral to the health and maintenance of male fertility, acting as an antioxidant and protector against environmental toxicity. It’s abundant in meats, dairy, beans, nuts, and seeds, and our 20mcg dose is sufficient to ensure you avoid deficiency. At healthy levels, selenium can:

Copper300 mcg

Prevent copper depletion*

Zinc supplementation is critical for maintaining testosterone levels, but it can cause a depletion in copper. Our formula ensures your copper levels remain in a healthy range. It can also help support a fitness regimen by:

Fenugreek Extract600 mcg

Double free testosterone*

More than just total testosterone, fenugreek can increase free testosterone — the version your body can actually use for things like muscle growth and sexual wellbeing. Our 600mg dose is standardized to 50% saponins. In 6-8 weeks, studies show that this dosage and strength can:

Tongkat Ali Extract400 mg

Improve testosterone and erectile performance*

Also known as longjack, this botanical provides a boost in both testosterone and erectile performance at just 200mg. Our dose is double that. Its highlights include:

Maca Root Extract200 mg

Enhance libido, erectile health, and sexual confidence*

While maca has been shown to improve symptoms in men with hypogonadism, its erectile benefits are even better documented. Our potent 10:1 extract provides an equivalent of 2,000mg maca powder, which can:

Black Pepper Extract5 mg

Ensure nutrient absorption*

It’s hard for the body to absorb all the ingredients in a supplement, but black pepper extract has been shown to increase absorption. This ensures you get more of the effect you want.

Ingredients We Don’t Include

Choosing what not to include is just as important as choosing what goes in. If an ingredient lacks sufficient evidence, raises meaningful safety concerns, or doesn't clearly improve the formulation, we leave it out, regardless of how popular it may be.

Supported By Clinical Research

In an 8-week trial of 57 young men, 600mg of daily ashwagandha resulted in an increase in total testosterone that was around six times higher than the modest increase in the placebo group.

Over the course of 12 weeks, free testosterone increased in the fenugreek group by around 23 points, while the placebo group saw a 23-point decline in the same period.

After just four weeks taking only 200mg of tongkat ali extract, men in the treatment group had 37% more salivary testosterone than those in the placebo group.

surpisingly strong
Ive been taking testosterone support for a little over 2 weeks at this point. I must say I was surprised by how stong the supplement felt, even in the first couple days. There were some negative effects at first. I would feel slightly light headed and strangely fatigued after taking the pills. Also, I got some mild Hemorrhoids starting about day 3 and lasting another 5 days or so. not a problem I usually have so I'm pretty sure they were from the supplement. Luckily they went away on their own. Now for the positives, of which there are quite a few. even early on I felt a change in my sleep quality. I sleep more deeply and also dream more each night. I've noticed some improvement in my workouts, I seem to be able to power through sessions better and mre easily than before. There have also been some sexual health improvements. erectile and orgasm quality have both improved significanty, alone making the supplement worthwhile. Overall I am happy with the effects of this supplement and plan to continue taking it for at least another three months.

Frequently Asked Questions

Testosterone is the primary male sex hormone and plays a role in the hormonal health of women as well. It’s responsible for the fetal development of male sex organs and the masculinizing effects of puberty, like a deepening voice, increased body hair, and the onset of fertility.

In adulthood, testosterone also regulates libido and sperm production, but its role extends far beyond sexual health or masculinity. It can control the balance between muscle and fat throughout the body while also ensuring sufficient bone strength as you age. Testosterone levels affect mood and energy levels and even influence the production of red blood cells.

Testosterone levels decline naturally as you age, with the most significant dropoff period beginning at around 40, after which you can lose up to 1% of your testosterone production every year.

We carefully formulated this supplement by following the science. Over the past several years, we spent thousands of hours poring over hundreds of research studies focused on what substances — vitamin, mineral, botanical — can safely and most reliably boost testosterone.

We’ve included copper in our supplement because we’ve also included zinc. Zinc has been shown to influence testosterone levels significantly. Copper hasn’t shown such influence, but research indicates that zinc supplementation can lead to copper deficiency, and we take great pains to ensure our product is as safe as it is effective.

While we formulated our supplement with safety in mind, as with any supplement, you should speak with your doctor before adding this supplement to your routine. This will ensure that the supplement is safe for you, specifically, based on your underlying health and any medications you are currently taking.

We ship internationally to Canada, Australia, Ireland, New Zealand, and the United Kingdom. These orders will ship DDP (Delivered Duty Paid) — meaning duties, fees, and taxes are collected at checkout — to ensure a smoother delivery experience for you, with no surprise charges upon arrival. (Learn more about our Shipping Policy).Innerbody Labs also ships to Army post offices.

Please note that international orders are all sales final, unless your order is missing or damaged. Please refer to our Refunds & Exchanges Policy.

Some may begin to notice results within the first week of use, while others will notice results several weeks or months later.

The ingredients within Testosterone Support improve testosterone levels and target the symptoms of low testosterone in different ways. Given this diversity of ingredients we’ve included, you could feel an increase in libido within days, though the full effects of the supplement and its impact on measurable testosterone levels will likely take closer to 12 weeks to arrive at their peak. After that, consistent use can maintain those positive results.

You can take Testosterone Support whenever it’s convenient for you within a given day. The ingredients aren’t intended to have instant effects, but men interested in maintaining the highest possible T levels might consider taking it in the morning. Testosterone levels are at their highest after you wake up, and they decline throughout the day, hitting their low in the evening. Taking your Testosterone Support dose with breakfast may influence that daily decline.

Innerbody Testosterone Support is intended for adult males. Women should consult with a physician before taking Innerbody Testosterone Support. We formulated this supplement specifically to support men’s testosterone levels, though there could be medical occasions where its ingredients could be recommendable to a woman, however rare those may be.
