onnit shroom tech sport ingredients

Vitamin B12 (750mcg)

Supports energy production and neurological health.

Vitamin B12 is one of those basic yet so important ingredients in any supplement. It’s found in animal products, mainly the organs such as the beef liver.

Your body needs B12 to make red blood cells as well as to produce energy. (2)

When your diet lacks vitamin B12, you might notice that you often feel fatigued. And you lack the motivation to do things you enjoy. This is why we like that it’s included in Shroom Tech Sport – helping to prevent deficiency.

Chromium (200mcg)

Helps to regulate blood sugar levels.

Chromium is a trace mineral that helps you with certain things. It promotes nutrient absorption along with supporting healthy blood glucose response when you eat a meal.

Chromium also helps with fat metabolism, and as such, it can be a great aid on your fitness journey. That’s why you’ll see it in many weight loss supplements. (3)

Most people don’t get enough chromium in their diets, however. You need at least 50mcg of it per day, and it’s estimated that most diets only provide 60% of this amount.

Shroom Tech O2 Blend (1.2g)

Anti-aging, pro-vitality, and may support testosterone production.

This blend only contains one main ingredient – Cordyceps mushroom.

Supplement companies have only recently started to include Cordyceps in their formulas. Though it’s been an integral part of Traditional Chinese Medicine for many years.

Cordyceps shroom supports your vitality, longevity and hormones. The science is still relatively fresh but it also seems that Cordyceps can boost testosterone in men. (4) No one yet knows how exactly it achieves this.

Shroom Tech Adaptogen Blend (930mg)

Helps you handle stress better.

This blend delivers four ingredients with unique benefits:

  • Ashwagandha

Rumors have it that Ashwagandha gives you the strength of a horse. According to science, these claims aren’t far from the truth. Ashwagandha is shown to promote strength, muscle hypertrophy, and testosterone. (5)

  • Green Tea Extract

It has potent antioxidants that protect your cells from damage and aging. Green tea also improves your mental well-being thanks to l-theanine and boosts up your metabolism to burn more fat. (6)

  • Astralagus

Astralagus helps with kidney function and the immune system. (1)

  • Rhodiola

Improves neurogenesis in the brain, makes you more motivated by raising dopamine levels, and enhances your mental and physical energy. Some people report that Rhodiola gives them vivid dreams. I can personally testify to this as it has had the same effect on me. Some people love it, others not so much! (7)

Does Shroom Tech Sport Have Caffeine?

Yes, Onnit Shroom Tech Sport does have a little bit of caffeine from green tea extract. But this amount is very small and is unlikely to have any effect unless you’re extremely sensitive to it. If you are sensitive though, be sure to talk to your doctor before taking any product that has caffeine.

Anything Missing?

Perhaps L-Carnitine, but it’s not essential since our body makes it on its own.

All in all, we’re happy with the Shroom Tech Sport formula. It has everything you need to support healthy energy production, resistance to stress, and overall mental and physical performance.

The most important part though is that the ingredients are all high quality with no harmful fillers or chemicals.

How to Take (Dosage)

The best dosage for Onnit Shroom Tech Sport is 4 capsules, 45 minutes before physical activity to boost energy levels. Onnit Shroom Tech Sport works best when you take it on an empty stomach.

You may also take it for an occasional energy boost. Just make sure not to ingest more than 6 capsules within 24 hours as that could lead to side effects!

Onnit Shroom Tech Sport could also technically be taken at night. But I’d still suggest not doing that as some of the herbs might actually prevent you from falling asleep. It also has a tiny dose of caffeine from green tea which might negatively affect your sleep. So again, if you’re taking it before your workout, it’s best to do it in the morning or afternoon!

How Long Does Shroom Tech Sport Last?

The energy boost from Onnit Shroom Tech Sport should last you at least several hours after ingestion. However, some of its ingredients build up in your system over time and have lasting effects. This especially applies to the mental benefits of the product.

For example, Ashwagandha doesn’t work immediately for most people but starts exerting its benefits within 1-2 weeks. Once these effects come, they stay there day and night until you stop taking the product.

Side Effects

If you’ve been with us so far in this Onnit Shroom Tech Sport review, then you’ve noticed that this supplement only uses safe and well-researched ingredients.

That said, you should be careful if you have any kind of medical condition. Ashwagandha can aggravate an autoimmune disease since it strengthens your immune system. The same can be said for Astralagus.

Is Onnit Shroom Tech Sport Good Value For Money?

It is in our experience. Since the product has a 90-day money-back guarantee on it, there’s no risk for first time buyers. Granted, the cost is a little bit high, and so it’s only for those serious about increasing their performance and energy. Like with any good product that works, you’ll have to pay a little more.

Conclusion on Onnit Shroom Tech Sport Review

So that brings our Onnit Shroom Tech Sport review to a close.

Is it worth the money? And will it work for you?

It all depends on what you’re looking for.

Does having more energy, being mentally sharper, and feeling less stressed sound like something you’d want? If so, Onnit Shroom Tech Sport will be an ideal choice for you.

Don’t think this supplement will give you overnight results though. You still need to stay active, eat healthily, and sleep well.

Onnit Shroom Tech is no miracle product and it doesn’t claim to be one, unlike many supplements with overblown marketing these days.

But yes, it works, and you’ll feel it the most during your training when you need to go the extra mile or push out those last few reps.
