This popular brand promises to enhance your performance and stimulate your body and mind safely and effectively without stimulants.

But does it really work? Is it legit?

In this Onnit Shroom Tech Sport review, we’ve dug deeper beyond the quality product packaging and good marketing strategy.

We’re here to find out what ingredients, results, benefits, adverse reactions, and expenses you could expect if you start consuming this workout supplement.

Let’s check out its real efficacy and value.

What Is Onnit Shroom Tech Sport?

Onnit Shroom Tech Sport

According to Onnit, Shroom Tech Sport is “designed to help the body with cellular energy and cardiovascular endurance” safely and naturally without stimulants (unlike many other similar products).

Consistent with this, it uses all-natural herbal ingredients rich in antioxidants, amino acids, and other beneficial components.

Besides the energy boost, increased endurance, and enhanced muscle power, this product promises a better mood, sharper focus, and less stress due to its adaptogenic herbs.

Onnit is a renowned US manufacturer of sports supplements endorsed by celebrities like Joe Rogan, Ken Blackburn, and others. The company is known for rigorous clinical testing of all their products to ensure safety, purity, and efficacy.

How Does It Work?

Onnit Shroom Tech Sport is claimed to increase oxygen and ATP (adenosine triphosphate) or the energy in your muscles, which then improves your focus, stamina, speed, and mental and athletic performance.

When your body utilizes its ATP and oxygen stores more effectively, your muscles will be able to recover from a high-intensity prolonged workout faster.

Also, you’ll feel less tired or stressed and more motivated to visit the gym frequently as it may also improve your mood.

Besides providing higher, pure energy boost on a cellular level, this supplement is said to enhance your strength, enabling you to lift heavier weights or perform more reps than you’d normally do.


Onnit Shroom Tech Sport Benefits

As mentioned, Shroom Tech Sport is a workout supplement that claims to increase your energy levels by improving the body’s ATP level. Beyond that, the manufacturer claims that it:

  • boosts training volume and physical performance
  • assists in energy production
  • enhances cardiovascular endurance

Shroom Tech Sport contains several vitamins, minerals, and adaptogenic herbs known for their physical and mental benefits such as higher resistance to stress, better overall mood, and enhanced cognitive function.

Let's continue this Onnit Shroom Tech Sport review by finding out what each ingredient is and how it helps to provide the benefits listed above.

Onnit Shroom Tech Sport Key Ingredients

Onnit Shroom Tech Sport has a total of 7 active ingredients, 5 of which are divided in two proprietary blends.

The O2 blend which is composed of two forms of one ingredient is included for maximizing energy utilization during workouts.

On the other hand, the adaptogen blend works to help with muscle endurance and recovery and overall mood and relaxation.

Vitamin B12 as Methylcobalamin (750 mcg)

Supplement Facts of Onnit Shroom Tech Sport Key

Methylcobalamin is an active, bioavailable, naturally-occurring coenzyme form of Vitamin B12. This particular form of vitamin B12 is commonly found in animal products such as milk, eggs, and meat. It's a basic yet essential vitamin that plays a critical role in various bodily functions.

Some of its numerous benefits include:

  • Supporting energy production
  • Contributing to the formation of red blood cells
  • Protecting immunity, DNA, RNA, and neurological health
  • Reducing homocysteine damage
  • Encouraging body detox
  • Stimulating serotonin production, improving mood and mental energy
  • Reducing stress and fatigue to ensure refreshing and relaxing sleep (when combined with Rhodiola), and much more. [1]

When your diet lacks vitamin B12 rich sources, you might notice that you almost always feel tired immediately or that you lack the motivation to do things you need and want to do.

A hefty dose of Vitamin B12 in this Shroom Tech Sport is sufficient to keep its deficiency at bay.

Chromium Picolinate (200 mcg)

Chromium Picolinate is an essential trace mineral that helps your body absorb other nutrients more efficiently and balance your blood sugar levels during workouts, especially after a meal. [2]

It also impacts fat metabolism, so it’s commonly found in fat burners and weight loss supplements.

Since most people don't get enough chromium from their diet, Shroom Tech Sport contains a little bit more of your daily chromium requirement to keep your blood sugar from spiking.

Shroom Tech O2 Blend (1.2 g)

Cordyceps Sinensis

The key active ingredient behind the patented Onnit Shroom Tech O2 Blend is Cordyceps Sinensis - a combination of the whole Cordyceps mushroom and Cordyceps extract.

This adaptogen used in traditional Chinese medicine for centuries is a “rare combination of a caterpillar and a fungus” that contains plenty of phytonutrients, cordycepic acid, and adenosine as its main components. [3]

This is the reason why supplements started including Cordyceps in their formula. Studies show that Cordyceps can:

  • Enhance the oxygen utilization in the body
  • Increase ATP as one of the main sources of cellular energy in the muscles
  • Improve aerobic capacity, athletic, and cognitive performance
  • Reduce fatigue
  • Regulate hormones
  • Promote libido and longevity, among various other health benefits. [4]

As a result, not only may you be able to train harder and longer for better and faster results, but also feel healthier overall. All that without excessive amounts of potentially harmful stimulants many similar products usually contain.

Shroom Tech Adaptogen Blend (930 mg)


Shroom Tech Adaptogen Blend contains the following ingredients, each with its amazing unique benefits to help you combat stress and feel more relaxed under high physical and mental pressure.

Ashwagandha (Root) Extract

Ashwagandha, also known as Indian Ginseng, is one of the most popular and important herbs in Indian Ayurvedic medicine. It is considered as an adaptogen as it helps your body manage and even reduce stress. Aside from this, it is also known to improve athletic performance, enhance sleep quality, and benefit your overall health in many other ways.

Specifically, ashwagandha is proven to:

  • increase muscle mass and strength
  • improve VO2 max performance
  • enhance muscle recovery
  • reduce cortisol levels effectively to help you fight stress and anxiety
  • improve mood and focus
  • increase energy levels
  • feel relaxed and rejuvenated [5] [6]

“Ashwagandha has been called the king of Ayurvedic herbs. Limited research suggests that it works well for reducing stress and anxiety. It may also modestly enhance strength performance, improve glucose metabolism, and increase testosterone levels, but more research is needed to confirm this.”

- Kamal Patel, MBA, MPH, Ph.D. (c) in Nutrition, Co-founder of

Green Tea Extract

Green tea extract is a powerful antioxidant rich in neuroprotective polyphenols and catechins to help your body fight free radicals. It is a popular ingredient in fat burners and weight loss supplements because green tea extract is known to increase the rates of fat oxidation and energy metabolism that aid in weight loss.

Other benefits of green tea extract include:

  • preventing cell damage and aging
  • boosting metabolism to aid in weight loss
  • increases energy and endurance
  • improves brain function [7] [8] [9]

Rhodiola (Root) Extract

A powerful Arctic herb Rhodiola Rosea works great with the other ingredients within this blend.

Interestingly, the less this natural adaptogen is used, the more power and potency it provides.

Research shows that it’s an excellent physical and mental energy booster, and performance enhancer that can also shorten recovery time after tough training sessions. It can also aid in faster muscle growth, and help your body better handle stress and exhaustion during exercise. [10] [11]

As a known adaptogen, it can reduce stress and increase dopamine levels, making you feel happier and more motivated to work out intensely.

Astragalus (Root) Extract

Like the other ingredients in this blend, astragalus is also a common adaptogen that has been used in traditional Chinese medicine to strengthen the immune system. It contains plenty of antioxidants to protect cells from oxidative damage.

This strong immunity booster has anti-inflammatory and stress-reducing properties that is also believed to enhance exercise performance and prevent exhaustion after a strenuous workout. However, evidence is quite limited so more research needs to be done. [12] [13]

Does It Work?

Even with all-natural and scientifically proven ingredients, a supplement does not always produce desirable results.

But Onnit Shroom Tech Sport has been shown to help boost energy levels and enhance physical and mental performance through rigorous clinical trials at FSU.

Some aspects where Shroom Tech Sport have the most impact are:

  • sprint performance
  • bench press and squat performance
  • resistance and high intensity interval training

Onnit Shroom Tech Sport Side Effects


Shroom Tech Sports contains scientifically-researched, safe, and natural ingredients in small quantities.

Users haven’t reported any side effects so far, so you shouldn’t experience any negative reactions if you’re healthy and don’t exceed the recommended dosage.

If taken in too high amounts, some ingredients may lead to side effects such as:

  • Sleepiness or autoimmune disease aggravation (due to Ashwagandha overdose because Ashwagandha and Astragalus strengthen your immune system)
  • Gastrointestinal issues caused by Astragalus
  • An increased risk of bleeding caused by too much Cordyceps
  • An excessive intake of Rhodiola extract can lead to occasional headaches
  • Clay-colored stools from too much Chromium Picolinate
  • Sleep disturbance due to a bit of caffeine from Green Tea Extract in people oversensitive to stimulants, or those who regularly drink a lot of coffee, tea, energy drinks, etc.

Always talk to your doctor before taking any supplements, especially if you’re already taking other medications or other supplements.

Onnit Shroom Tech Sport Missing Ingredients

I am quite impressed with the all-natural ingredients in Shroom Tech Sport which are scientifically proven to improve muscle endurance and strength. But perhaps, it would be nice to have some amino acids in the mix, specifically L-Carnitine and L-Tyrosine.

Both these amino acids help boost energy levels, enhance focus and clarity, and improve muscle recovery.

Still, I'm satisfied with the all-natural Shroom Tech Sport formula, except for their use of proprietary blends. It has everything needed to support energy production, stress reduction, and overall physical and mental performance.
