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

Does it work? Is it legit?

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

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

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’s using all-natural herbal ingredients rich in antioxidants, amino acids, and other beneficial components.

Besides increased energy, endurance, and 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), i.e. the energy in your muscles, improving your focus, stamina, speed, athletic and mental 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 on a cellular level, this supplement is said to boost your strength, enabling you to lift heavier weights or perform more reps than you’d normally do.

Shroom Tech Sport Key Ingredients

Vitamin B12 as Methylcobalamin (750mcg)

B12 Vitamins

Methylcobalamin is an active, bioavailable, naturally-occurring coenzyme form of Vitamin B12. This essential nutrient plays a critical role in various bodily functions.

Its numerous benefits include:

  • Supporting energy production
  • Contributing to red blood cell formation
  • 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]

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

Chromium Picolinate (200mcg)

Chromium Picolinate is an essential trace mineral that helps your body absorb other nutrients and balance your blood glucose levels during workouts. [2]

Chromium also impacts fat metabolism, so it’s commonly found in fat burner supplements.

Shroom Tech O2 Blend (1.2g)

Cordyceps Sinensis

The key active ingredient behind the patented Onnit’s 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” containing plenty of phytonutrients, cordycepic acid, and adenosine as its main components. [3]

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 feel healthier overall. All that without excessive amounts of potentially harmful stimulants, many other products like this usually contain.

Shroom Tech Adaptogen Blend (930mg)


Another Onnit’s proprietary 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

This adaptogen superherb is proven to increase muscle mass and strength, VO2 max performance, enhance recovery, reduce cortisol levels effectively to help you fight stress and anxiety, improve mood and focus, boost energy, feel relaxed, rejuvenated, and benefit your overall health in many other ways. [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 Examine.com

Green Tea Extract

This potent antioxidant, rich in neuroprotective polyphenols and catechins, helps your body fight free radicals to prevent cell damage and aging, boosts metabolism to aid in weight loss, increases energy and endurance, improves brain function, etc. [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 it’s an excellent physical and mental energy booster, endurance, and performance enhancer that can also shorten recovery time after tough training sessions, aid in faster muscle growth, and help your body better handle stress and exhaustion during exercise. [10] [11]

It can increase your dopamine levels, making you feel happier and more motivated to work out intensely.

Astragalus (Root) Extract

This strong immunity booster with anti-inflammatory, stress-reducing, and other health benefits is also believed to enhance exercise performance and prevent exhaustion after a strenuous workout, but the evidence is limited. [12] [13]

  • 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

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