You may encounter Onnit as you look for quality nootropics to target memory, focus, and mental processing.

However, their nootropics, like Alpha Brain, are just a few among the range of products that Onnit offers.

Onnit is a Texas-based health and wellness company that manufactures products designed to help people reach their peak performance by offering fitness equipment, nutritional foods, and capsules and providing health and diet information readily accessible to consumers.

As Onnit product reviews circulate online, you may still be thinking about a lot of questions regarding its effectiveness and safety.

Is Onnit legit? Let’s dive in to know the answer.

What Is Onnit?

Onnit Labs has been in the health industry for more than 10 years already. Its company is based in Texas and serves customers in the United States. Since its founding, Onnit has been incorporated with over 250 products, from nutritional capsules to fitness equipment.

This multi-million dollar company was founded by Aubrey Marcus, a multisport athlete who built this company based on a holistic health philosophy called Total Human Optimization. This aims to empower customers to achieve their fullest human potential. The launching of the company’s flagship supplement, Alpha Brain, marked the beginning of Onnit’s journey.

Most of Onnit’s products, such as Alpha Brain bear certification from various known organizations like Rainforest Alliance and UTZ. To further raise their value and ensure quality and safety, their merchandise is continually tested for purity and illegal substances.

As the firm’s flagship product, Onnit Alpha Brain is supported by clinical studies published in scientific journals. It is said to improve memory, attention, and other cognitive functions to eliminate brain fog and focus on complex tasks. Aside from Alpha Brain, Onnit is also known for manufacturing kettlebells with carved gorilla faces called Primal Bells.

Does Joe Rogan Own Onnit Alpha Brain?

Rogan is one of the biggest independent media personalities. As an active person and a relentless fitness enthusiast, he has been a supporter of Onnit products such as Alpha Brain capsules for mental clarity, Onnit’s kettlebell, as well as Onnit’s New Mood for daily stress support.

Rogan hosts a podcast where he talks about his incredible experiences from using Onnit. One of the capsules that he would recommend to his listeners is the Onnit Alpha Brain, which improves cognitive functions to accomplish tasks with focus. As a nootropic backed with clinical trials and research, Rogan firmly believes that taking Alpha Brain is worth his time and money as it helps him in recalling words; Just as he said, “I feel like it helps me form better sentences.“

Onnit Alpha Brain Instant and Other Offered Supplements

Onnit capsules are built from the best earth-grown nutrients and consist of various scientifically-proven and natural nootropic ingredients. These are said to be the foundation of the company’s leading brand: Total Human Optimization.

One of the most popular is the Onnit Alpha Brain Instant. Onnit Alpha Brain Instant is a nootropic powder mix that targets improved cognitive function and memory by optimizing alpha waves in the brain. Alpha Brain allows you to have a productive day free from distractions.

You can get Alpha Brain Instant in different flavors, but its content is also the same as the nootropic capsules’ ingredients.

Some of the notable ingredients found in Onnit Alpha Brain are L-Theanine, L-Tyrosine (Both L-Theanine and L-Tyrosine are essential amino acids and good nootropic substances), Phosphatidylserine, Oat Straw extract, Alpha-GPC (Alpha GPC is a powerful cholinergic for greater faster mental speed), Huperzia Serrata, Bacopa extract, L-Leucine, Pterostilbene, Cat’s Claw Extract, AC-11, and Vitamin B6.

Aside from its flagship product, Onnit offers a range of other capsules in different categories: Focus + Brain in which Alpha Brain capsule and Instant are under, Mood + Sleep to support sleep and relaxation such as the New MOOD supplement, Melatonin Spray and ViruTech, among others.

Other categories are Digestive Health, Support, and Vitality, Essential Nutrients to support total body health, Performance, Immune System, and Total Human, which is a day and night pack complete with essential vitamins, herbs, amino acids, and minerals.

Benefits & Side Effects of Taking Onnit Supplements

Since Onnit has several dietary capsules aside from Alpha Brain, their benefits differ from one another depending on the target optimization.

Onnit Total Human, one of Onnit’s best sellers, enhances brain health, boosts mood, and supports the immune system and bone health. Since this is a caffeine-free dietary supplement, same as the rest, this is not intended to diagnose, treat, cure, or prevent any disease.

In an Alpha Brain review and Onnit supplements review, it was mentioned that Onnit believes that these nutritional capsules can help anyone be optimized as improving one area can bring about change universally.

Onnit Alpha Brain is one of the safest nootropic pills available in the market. However, if you take Alpha Brain, which consists of different proprietary blends, side effects are inevitable as these vary depending on the body’s reaction.

The same goes for other capsules available in Onnit, especially when more dosages are taken than recommended, if combined with another supplement or medication, or if there is a presence of a health condition, when it might make sense to consider an Alpha Brain alternative.

In Alpha Brain, the maximum limit of dosage is two capsules, while 6 capsules within 24 hours are recommended for Shroom TECH Sport and New Mood. To know the right dosage for others, you can check it on their website.

Based on an Alpha Brain and Onnit supplement review, some of the common side effects are the following:

  • Stomach ache – You may experience this if you are not accustomed to using dietary pills.
  • Nausea – Taking these pills could cause you to feel nauseous, especially when taken on an empty stomach. To avoid having nausea, you must take the capsules with a light meal.
  • Headache – This is common with all dietary pills, which could be overcome after your body gets used to it.

Since the side effects are not exclusive to each supplement, the mentioned above are general for nutritional capsules. Therefore, utmost caution is advised, so you must consult your doctor before taking any of these.

How Much Do Onnit Supplements Cost?

The dietary capsules differ in price depending on the amount per bottle. A 30 count Alpha Brain costs $34.95, while a 90 count bottle is worth $79.95.

The Total Human pack costs $137.95 and $275.90 for a 30-day supply and 90-day supply package.

The others are available with a $12 to $99 price range.

There’s also an Onnit Alpha Brain free trial that you can use to get a free sample of the supplement.

Are Onnit Supplements Worth It?

Based on some Onnit supplement reviews online, Onnit offers effective products, which makes it worth trying.

The capsules are also drug-free and certified with Gold Star Standard by the Banned Substance Control Group. For instance, Onnit Alpha Brain is backed by clinical evidence and has double-blinded case studies to ensure its effectiveness in improving cognitive performance effectiveness.

Although no report shows adverse effects from using the pills, you could still experience mild to adverse effects that vary from different users. This is especially true for consumers who are still getting used to it, similar to the experiences of people who used Alpha Brain.

However, it is important to know that some are underwhelming with their ingredients supported by little to no research. Some are also included in proprietary blends, making it hard for consumers to know the dosage per ingredient. Similar to other dietary pills, Onnit’s are also not certified by the FDA.

Where to Buy Onnit Supplements? 

There are physical stores where you can take your Onnit supplement, but you can have yours through online stores to save time.

For an easy transaction, great deals, and to ensure that you get the right product, it is recommended to get these capsules on their official website, Onnit.com.

For a limited time only, you can buy yours with free shipping for orders over $150. This excludes equipment from the Fitness section and is valid only in the U.S.

For inquiries, you can contact their email address – help@onnit.com.


Onnit has built a great reputation in the health and lifestyle industry with over 250 products in its arsenal and a lot of users and supporters.

Since every brand has different components and targets different kinds of body optimization, it is essential to check out each one and know which feels like the best supplement for you.

Despite some side effects and cons, there may be one product from Onnit that best suits your body that can help you achieve your goal.
