Shroom TECH Sport Review

Shroom TECH Sport is a mushroom-based adaptogenic supplement that can improve endurance and exercise performance.

Have you ever felt like you couldn’t put forth the amount of effort you were hoping for when working out? Or maybe just in your day-to-day life, when’s the last time you felt like you were depleted of all your energy levels?

This is an extremely common feeling that most people feel sooner or later. As we get older, our bodies naturally produce less energy, and it affects the way we act and behave. The rate at which that occurs can be altered with a combination of a healthy diet and healthy habits, but most people don’t pay attention to those things.

This is why most people turn to supplements like Shroom TECH Sport by Onnit Labs to help restore their energy levels and keep them firing on all cylinders throughout the day.

If you’re interested in Shroom TECH Sport, today’s review will explain everything you need to know about it. We’ll discuss its ingredients, benefits, side effects, cost, and more and give you our final verdict on this supplement.

Shroom TECH Sport Supplement

About Shroom TECH Sport

Shroom TECH Sport is a mushroom supplement offered by Onnit Labs, which is home to a wide range of supplements. Onnit Labs also produces Onnit Total Human, as well as a variety of other supplements that include protein, nootropics, vitamins, and various different performance formulas.

Shroom TECH Sport is heavily marketed for workout enthusiasts looking for an extra daily boost when exercising, but it can truly be utilized by anyone looking for a natural energy boost. Students, workaholics, stay-at-home mothers, and video game enthusiasts can all benefit from this supplement.

The ingredients found in Shroom TECH Sport, which we’ll detail further below, are designed to increase cellular energy inside the body. This is a process that occurs throughout the day but can be damaged due to normal aging and environmental complications.

Shroom TECH Sport

Why is cellular energy important?

Cellular energy drives the various functions and processes occurring inside the body. Since each cell has its role in maintaining a healthy body, it’s essential that those cells have the energy they need to carry out that role.

The energy inside the cell is produced by the mitochondria found inside the cell. Ensuring your cells have healthy mitochondria is the key to having a surplus of cellular energy. Unfortunately, time doesn’t treat your cells or mitochondria well.

Eventually, the mitochondria won’t be able to produce cellular energy the way they used to. This happens without warning, and there’s no cure for it — it’s just a normal part of the human body’s aging process. This process is what supplements like Shroom TECH Sport are designed to slow down, allowing you to live a healthier and longer life.

What claims are made by Onnit Labs about Shroom TECH?

Before we start looking at some of the specifics behind this supplement, it’s important we understand what it is that Onnit Labs is selling. We can view this by looking at how they market their product and what claims they make.

The main thing we’ll be on the lookout for is claims with scientific evidence to support them. Making bold claims might make the product look better, but it doesn’t mean that product is better. With that being said, let’s see what claims Onnit Labs makes about Shroom TECH Sport:

  • Helps the body with cellular energy
  • Improves cardiovascular endurance
  • Boosts exercise volume and aerobic performance
  • No gluten, dairy, nuts, soy, sugar, GMO, or allergens
  • Vegan- and Keto-friendly
  • BCSG-certified

As you can see, they keep it relatively simple with the claims and don’t make any hard guarantees. They reassure the customer that the product is safely made without any banned substances and features healthy ingredients.

Of course, we’ll take a deeper look at whether or not they follow through on the claims they made when we break down the ingredients.

Are there any tests that prove Shroom TECH works?

We want to mention a clinical trial Onnit Labs did in accordance with Florida State University. It was a “rigorous” trial by their standards, but it did look at the effects this capsule had on the human body when compared to a placebo.

The clinical trial looked at training volume, strength, VO2 max, body composition, and hormonal profiles when taking the supplement. Since it was a double-blind study, no one knew whether they had a placebo or supplement.

The results showed an increase in performance when taking the supplement in three significant areas — reps on the bench press, reps of bench press and squats combined, and time on the treadmill. The people taking the supplement had more energy and could withstand much more during their workout.

Shroom TECH Sport Ingredients

Now that we’ve had a chance to review some background information about Shroom TECH Sport let’s start looking at what we’re really here for — the ingredient list. This is where we see whether the claims made by Onnit Labs’ are reality or just smoke.

There are seven ingredients in total, but we only know the exact dosages of two components — 750mcg of Vitamin B12 and 200mcg of Chromium. The other five ingredients are split between two blends — 1,200mg of O2 Blend and 930mg of Adaptogen Blend.

Shroom TECH Sport Supplement facts

Let’s dive in!

Vitamin B12

Also referred to as cobalamin, Vitamin B12 is one of the eight B-complex vitamins that play a significant role in how the body breaks down food for energy. It’s commonly found in beef, chicken, fish, eggs, and some dairy products.

Vitamin B12 is required to produce DNA, produce red blood cells, regenerate bone marrow and the lining of the digestive tract, the health of your nervous system, and prevent anemia. Much like cellular energy, our Vitamin B12 levels are known to decrease as we age.

Recommended Dosage: 2.4mcg through diet, but safe in higher doses (water-soluble vitamin)


Chromium is a mineral found in beef, poultry, dairy, fruits, vegetables, and whole-grain products. There are two main forms of chromium — trivalent (found in food) and hexavalent (toxic; found in pollution). Trivalent chromium comes in several different forms itself, but Shroom TECH utilizes Chromium Picolinate.

Chromium not only helps control blood sugar levels in the body but also aids the action of insulin and improves metabolism. Some studies show it to be beneficial against Type 2 Diabetes and help patients during weight loss.

Recommended Dosage: 35mcg per day through diet, no higher than 250mcg per day

Shroom Tech O2 Blend

The Shroom Tech O2 Blend, which is a 1,200mg blend, contains Cordyceps mushroom. This supplement utilizes both whole Cordyceps mushroom and whole Cordyceps extract. Mushrooms are becoming more popular in natural energy supplements (such as Mud WTR and Four Sigmatic Coffee).

The Cordyceps mushroom is one of the 15 known functional mushrooms, which are mushrooms that have benefits beyond their nutritional benefits. The Cordyceps is unique for growing on the back of larvae insects.

Aside from being a dense nutrient, the Cordyceps mushroom is known to help the body produce ATP (energy). This gives your body a natural energy boost and helps the body use oxygen. In addition to that, this mushroom has strong anti-inflammatory properties and provides the body with antioxidants.

Recommended Dosage: 1,000-3,000mg per day

Shroom Tech Adaptogen Blend

The Shroom Tech Adaptogen Blend, which is a 930mg blend, contains four ingredients —  Astragalus, Rhodiola Rosea, Ashwagandha, and Green Tea Leaf. As the name suggests, these four ingredients are known to provide adaptogenic benefits to the body.

Adaptogens help the body deal with, manage, and relieve stress or anxiety. Let’s take a closer look at these four ingredients and how they help the body respond to stress:

  1. Rhodiola Rosea – an ancient herb that eases stress, reduces fatigue, fights depression symptoms, improves cognitive function, and helps exercise performance.
  2. Ashwagandha – an ancient herb that relieves stress, increases energy, improves concentration, reduces blood sugar levels and inflammation in the body.
  3. Astragalus – an ancient plant that improves heart health, relieves stress and anxiety, helps improve allergy symptoms, improves sleep, has anti-aging properties, and boosts the immune system.
  4. Green Tea Leaf – loaded with antioxidants, reduces inflammation, improves brain function, increases fat-burning, reduces bad breath, and has anti-aging benefits.

All four ingredients come with heavy scientific evidence; our only wish is that we knew the dosages of each ingredient.

We can say the recommended dosage of each ingredient is: 300mg of Green Tea Extract, 2,000mg of Astragalus, 400mg of Ashwagandha, and 250mg of Rhodiola Rosea.

Shroom TECH Sport Pros vs. Cons

We’ve taken a quality look at the background behind this product, the ingredients used by Onnit Labs, and how much the product will cost the consumer. While that’s enough information for anyone to make an informed decision when purchasing this supplement, it’s understandable if you’re still on the fence.

To help you narrow your decision, we will detail the various benefits and downfalls of purchasing Shroom TECH Sport. It’ll also give you a summary of everything we’ve discussed thus far.


  • Increases cellular energy and cardiovascular endurance
  • Can improve exercise performance and overall daily energy
  • No gluten, dairy, nuts, soy, sugar, GMO, or allergens
  • Vegan- and Keto-friendly
  • BCSG-certified
  • Cordyceps is a popular functional mushroom that increases ATP (body’s energy molecule)
  • Ashwagandha and Rhodiola are ancient adaptogens that boost energy and cognitive function
  • Vitamin B12 and Chromium are a powerful vitamin-mineral duo for increasing energy
  • Green Tea Extract will give you a boost of energy as well
  • Not going to break the bank
  • Can easily lower the dosages by taking fewer capsules


  • four capsules per serving is a bit excessive
  • Doesn’t give the exact dosage of each ingredient
  • Could’ve also utilized Citrulline, Creatine, Theanine, Tyrosine, or Iron

Claims vs. Reality

Earlier in this review, we briefly looked at the claims and guarantees made by Onnit Labs for Shroom TECH Sport. Now that we’ve taken a look at the product up and down, we can take a look back at those claims and confirm their truth.

A majority of the claims made were centered around exercise performance. They claimed this product would help you get more out of your workouts, improve cardiovascular endurance, and boost energy levels.

After looking at the ingredients, it’s clear that they did an excellent job of choosing quality ingredients. The Vitamin B12, Green Tea Leaf Extract, and Cordyceps mushroom will help boost energy levels. At the same time, the Ashwagandha and Rhodiola Rosea will help calm you down so you can focus on the task at hand.

As far as we can tell, they use healthy doses of each ingredient. It would help if they were more transparent, but the 1,200mg of Cordyceps is a safe and effective dose. Likewise, it would be difficult for the 930mg blend (Green Tea, Astragalus, Ashwagandha, Rhodiola) to be split up improperly.

Shroom TECH Sport Side Effects

The ingredients in Shroom TECH Sport are generally safe when consumed as guided. However, cordyceps, astragalus, or ashwagandha may cause nausea or stomach discomfort. 

Shroom TECH Sport Cost & Serving

Onnit Shroom TECH Sport can be bought directly from the official Onnit website here. Each bottle comes with 28 capsules, but each serving is four capsules. That means you only get seven servings in their small bottle, which costs under $25.

You can also purchase a bottle with 84 capsules for $56, which would last 21 days when taking a full serving each day.

Shroom TECH Sport Tablets

Of course, you can make the bottle last twice as long by taking two capsules daily. It’ll be a lighter benefit, but it will still be enough to help give you a boost each day if you’re on a budget.

Shroom TECH Sport Alternatives

As we learn more about cellular energy and its role in our daily and long-term health, more supplements are being added to the market — all of which claim to do the same thing as Shroom TECH Sport.

While Onnit Labs is home to some of the more popular cellular energy supplements, there are plenty more you should consider. To help you separate effective supplements from the hype, we will detail some of the bigger names in the market.


TruNiagen is home to one ingredient — Nicotinamide Riboside Chloride. It helps increase the body’s NAD+ levels, which helps the cells and mitochondria produce energy more effectively. Studies suggest we lose nearly half of our NAD+ levels between 40 and 60.

It comes with various clinical trials supporting this single ingredient and is effective enough for TruNiagen to have its patented version of the ingredient. You can purchase one bottle (month’s supply) for $50 or a three-month supply for $120.

Qualia Life

While TruNiagen is a much simpler formula when compared to Shroom TECH Sport, Qualia Life is a much more complex formula. It features 34 ingredients and will help increase productivity and energy levels, improve sleep, support mitochondrial health, and boost NAD and ATP levels inside your cells.

As effective as Qualia Life is — which features L-Carnitine, ElevATP, Coenzyme Q10, Ashwagandha, Tryptophan, and much more — it is pretty expensive. Each bottle costs $160 and will only last you one month. It’s also available in a powder drink formula for the same price, in case you don’t like capsules.

Instant Mushroom Coffee

For a unique experience, Four Sigmatic offers an Instant Mushroom Coffee blend with Chaga and Cordyceps mushrooms. They utilize an Instant Coffee formula with a wonderful taste, but they also add the power of two of the most popular functional mushrooms out there.

Chaga mushrooms give your immune system a powerful boost, while the Cordyceps mushroom helps boost energy and endurance. If you’re an avid coffee drinker, this will help bring some new pizzazz to your morning cup of joe.

Each box comes with ten individual packets that only cost $15 per box (a little over $1 per packet). It’s affordable, highly effective, and doesn’t require you to change your routine at all!

HealthyCell Pro AM/PM

If you’re looking for a formula full of surprises, HealthyCell has you covered with their Pro AM/PM Cell Health System. It contains over 90 ingredients and features two different pills, one you take in the morning and one you take in the evening.

Each pill is designed to give your body and cells the nutrients they need at the right time of day. The Morning Formula targets your body’s energy, focus, mental clarity, and optimal cell function. The Evening Formula targets your body’s ability to revitalize, detoxify, restore, and repair the cells while sleeping.

Each box will last you one month and cost you $130. While it’s on the expensive side, the formula is one of the best on the market. You’ll be getting what you paid for, no doubt about it.

Final Verdict: Shroom TECH Sport

Shroom TECH Sport by Onnit Labs is an effective supplement that helps boost energy and endurance, especially during a workout or any strenuous activity. It might not be the most potent supplement on the market, but it is one of the cheaper ones.

Ashwagandha and Rhodiola Rosea are two of the most popular ingredients linked to traditional Ayurvedic medicine. They’ve been used for hundreds — maybe thousands — of years and come with plenty of scientific evidence. The addition of Cordyceps mushrooms only adds to the benefit.

If you’re looking for a simple yet effective energy supplement that isn’t going to pack your body with caffeine, Shroom TECH Sport is a solid option and should definitely be considered — among the other supplements we discussed above.
