Onnit Supplements Review

Best Onnit Supplements

In today’s overcrowded supplement market, it can be hard to figure out which suppliers are legitimate.

Onnit Supplements sets itself apart–this company focuses on what they call “total human optimization,” and they offer more than just supplements.

Onnit sells unique training implements, offer protein powders and other nutritional products, and even operates a gym in Austin, Texas. It’s an interesting company for sure, but is Onnit Supplements all it claims to be?

Let’s find out.

Who is Onnit?

Onnit supplements review

Onnit Supplements was founded by multisport athlete Aubrey Marcus in 2011. Onnit started with a single supplement–Alpha BRAIN–and grew from there. In the company’s mission statement, they say they’re committed to bettering mental, physical, and spiritual health.

Their supplement lineup seems to reflect it, too–they offer supplements for brain health, mood, and gut health, along with the performance-based supplements you’d usually expect. Their products are all backed by research, and they also have a link on their site to clinical trials done with their formulas.

Onnit supplements review

Even a quick scan through their site indicates that this company is committed to its mission–Onnit devotees near Austin can visit their gym, grab a healthy lunch or snack at the Onnit Cafe, or take a class at one of their Black Swan Yoga locations. And no matter where you live, you can follow founder and CEO Aubrey Marcus’s podcast. In this review, we’ll primarily focus on Onnit’s supplement lineup, but we’ll talk a little about their training products and Marcus’s podcast, too. But first, here are some of the pros and cons of the company:

Pros + Cons of Onnit


  • This company has a following of pro athletes and celebrities who believe its products are effective
  • All products are third-party tested for quality
  • Onnit supplies site visitors with information on the clinical trials behind its supplements
  • The founder and team do seem committed to wellness


  • Many supplements use proprietary blends, so buyers can’t see exactly how much of each ingredient they’re getting
  • Many supplements are fairly expensive

Top Onnit Supplements


As the flagship supplement of Onnit, Alpha BRAIN still enjoys significant popularity. Part of this is due to Joe Rogan’s notable endorsement. However, as a lifestyle brand, Onnit works extensively with celebrities and influencers–for the average consumer, it’s still important to actually investigate the ingredients.

A quick look at the ingredient label of Alpha BRAIN shows that it primarily relies on vitamin B6 and a handful of amino acids. On the front of the bottle, Bacopa monnieri and Huperzine-A get a special mention. Bacopa monnieri has been shown to improve memory and cognition, but the standard dose is 300 mg–a serving of Alpha BRAIN only has 100 mg. Huperzine-A seems to be included in an effective dose, and it’s been shown to promote acetylcholine, which is also known as the “learning neurotransmitter.”


  • Most ingredients are backed by clinical research
  • Having multiple ingredients in one supplement is easier than buying each one separately
  • This supplement has been endorsed by prominent people


  • Many ingredients are part of proprietary blends, so you can’t tell exactly how much is included
  • Alpha BRAIN is very expensive considering its ingredients

Alpha Brain Ingredients

The key ingredients contained are Alpha GPC and HuperziaSerrata.Other ingredients of the Alpha brain supplement include; Pterostilbene, L-Leucine, Vegetarian Capsule (Cellulose, Water), Bamboo Silica, Phosphatidylserine, AC-11 (UncariaTomentosa).

Joe Rogan and Alpha Brain

Joe Rogan has publicly stated his love and support for Alpha Brain, as much as we love Joe Rogan he also has part ownership of Onnit so take that into account.

Where to Buy Alpha Brain

Alpha brain can be purchased at Whole Foods and Amazon. But we recommend buying it on Onnit.com below for the best prices and a free trial!


onnit new mood review

When you think of a nootropic supplement for mood, you might imagine something designed to energize you and elevate your mood. New MOOD is meant as a relaxing supplement or a stress management tool. Onnit claims that the ingredients 5-HTP and L-tryptophan work to synthesize serotonin. However, most existing research doesn’t support this claim, and some has even found that 5-HTP shouldn’t be used by people with existing depression.

The other ingredients include magnesium, valerian root, and lemon balm, which can help you feel relaxed and sleep well. These ingredients are mainstays in relaxation supplements, and most are supported by research. Of course, if you’re already tired or fatigued during the day, this might be a supplement that you should only take at night.


  • Some ingredients (like valerian) have been shown to promote relaxation and refreshing sleep
  • Using a combination of ingredients means this supplement may work for more people


  • Most research contradicts the claim that 5-HTP works to synthesize serotonin
  • While other ingredients are effective, you can find them cheaply elsewhere

Onnit Total Human

If you’re the type of person who wishes they could buy every supplement a given company offers, Total Human might be a product for you. Onnit markets it as “better than a multivitamin,” and it’s essentially a collection of some of their top-selling supplements. You can choose day packs (supplements designed to power you through the day), night packs (supplements to support restful sleep), or both.

Total Human Free Trial

Onnit now offers a free trial!

The day pack includes most of their top sellers:

  • Alpha BRAIN
  • Shroom TECH Sport
  • Stron Bone
  • Total Human B Complex

The night pack includes top seller New MOOD along with some lesser-known supplements:

  • New MOOD
  • ViruTech
  • Key Minerals

There’s also a selection of supplements that comes with both packs:

  • Shroom TECH Immune
  • Krill Oil
  • Spirulina and Chlorella

Onnit says that buying this way saves you 40% over buying supplements individually. And while it may well be better than a multivitamin, it’s still pretty expensive.


  • Offers an easy way to take many different supplements
  • Offers significant cost savings over buying individually


  • As mentioned above, some Onnit supplements are of dubious quality
  • Total Human is a fairly expensive option

Shroom TECH Sport

shroom tech review

Many people visit supplement sites with the intention of buying a supplement that helps with workout performance, and Shroom TECH Sport is intended to do just that. This formula was also tested on regular gym-goers and was found to improve their performance in ways that were statistically significant. This was a small study, but it’s an important point in the supplement’s favor.

The ingredients in Shroom TECH Sport are largely herbs from traditional medicine. Cordyceps sinensis (the mushroom that inspired the “shroom” in the name) is a major ingredient, but there’s almost no research that supports Onnit’s claim that it supports endurance. Other ingredients include the adaptogen Ashwagandha, concentrated green tea extract, rhodiola, and vitamin B-12.


  • Research on this specific formula is promising
  • This formula combines several popular workout supplements


  • Aside from the cited study of the exact formula, little to no research substantiates Onnit’s claims
  • As with most Onnit supplements, this one is also fairly costly

Pre Workout

onnit preworkout

Like Shroom TECH Sport, this pre-workout formula, called Total Strength + Performance, has been tested in a double-blind trial against a placebo. It showed significant performance improvements in major lifts over four weeks.

When it comes to ingredients, though, this formula is somewhat unremarkable. It contains high levels of B-vitamins, and it also contains a 4.5g blend of BCAAs and beta-alanine. However, because the blend is proprietary, you can’t know if the BCAA ratios are optimal, and you don’t know how much of each ingredient you get.

One of the ingredients highlighted by Onnit is longjack, an herb that is commonly found in testosterone boosters. There’s a small amount of research suggesting that it may improve power output, but otherwise, there’s almost no research to support its efficacy.


  • Contains an array of ingredients that do support energy (especially B vitamins)
  • Comes in a few different flavors
  • Also includes BCAAs, which some people buy as a separate supplements


  • Key ingredients like BCAAs and beta-alanine are part of proprietary blends, so you can’t tell how much you’re getting
  • Some key ingredients aren’t supported by research

Onnit Protein Powders

onnit protein powder

For most athletes, protein is a vital part of supplementation. Onnit offers a variety of protein supplements:

  • Grass-fed whey protein isolate
  • Plant-based protein
  • Post-workout protein (whey isolate, BCAAs, creatine)
  • Protein bars
  • Protein bites

Onnit’s proteins appear to be ethically sourced, and they come in a variety of flavors. The bars and bites are also an enjoyable, non-shake way to add a little more bioavailable protein to your diet.


  • Whey isolate is the best form of whey for muscle gains
  • Powders and snacks are nutritionally balanced
  • Interesting flavors like Mexican chocolate help add some variety


  • These products are more expensive than many similar offerings from competitors


onnit MCT oil

Somewhat recently, MCT oil became one of the newest buzz-generating supplements. MCT stands for “medium-chain triglycerides,” and they are fatty acids that are metabolized relatively quickly. MCT oil may increase energy and boost basal metabolic rate.

There’s some research supporting its ability to boost metabolic rate and encourage the body to burn fat, although its effects are not dramatic.


  • Quality oil is sourced entirely from coconuts
  • May be a good way to consume enough healthy fats when dieting
  • Has some impact on energy levels and fat burning


  • Onnit seems to overstate the benefits of MCT oil a bit

Total Gut Health

onnit total gut health

Gut health is something that’s connected to brain health and general well-being. Sometimes, in order to feel great and perform optimally, your gut needs a little help. Total Gut Health inlcudes several ingredients to help balance gut flora:

  • Prebiotics–These ingredients help support the growth of helpful gut microorganisms.
  • Probiotics–These ingredients restore gut flora and support healthier digestion.
  • Digestive enzymes–These ingredients may support healthier digestion
  • Betaine HCl–Promoters of this ingredient claim that it supports digestion, but there’s little to no research supporting this.

While most people benefit from prebiotics and probiotics, the benefits of the other ingredients are less certain.


  • Some ingredients may help improve gut health, which improves overall health
  • An all-in-one gut supplement is easier than buying separate supplements


  • The benefits of digestive enzymes and betaine HCl are much less clear

Total Hemp

Onnit Supplements Review

Total Hemp is a highly potent, bioavailable hemp product that’s sustainably sourced and free of THC. This product is designed with a VESIsorb delivery system that’s clinically proven to promote bioavailability, making it a much more effective hemp product compared to competing brands.

Total Hemp is made with  100% field-grown, broad-spectrum hemp extract and is great for first-time buyers of hemp products. The phytocannabinoids contained in this product promote better sleep, enhance overall relaxation, and help regulate perceptions of discomfort.


  • Once-a-day
  • 100% field-grown, broad-spectrum hemp extract
  • THC-free


  • Not suitable for people with allergies to tree nuts
  • Not suitable for vegetarians or vegans

Onnit Founder Aubrey Marcus

Aubrey Marcus started Onnit, and the company has since grown exponentially. As a lifelong athlete, he began developing supplements to help others achieve wellness. Marcus is especially well-known for his podcast. While you might expect this podcast to be sport-focused, many episodes involve philosophical conversations with prominent figures. True to the goals of the company, this is a podcast that seeks to help people develop in mind, body, and spirit.

Joe Rogan and Onnit

Onnit supplements review

A lot of people think of Joe Rogan when they think of Onnit. The two first met when Marcus was marketing Fleshlights, and they struck up a deal–Fleshlight sponsored Rogan’s podcast, and Rogan advertised the product on his podcast. Marcus and Rogan became close friends based on common interests, and they worked together to build Onnit. Rogan is still a business partner at Onnit, and he recommends many of their products on his podcast and social media.

Onnit Academy

For those who want some additional guidance when it comes to reaching goals, Onnit Academy offers workouts, motivational interviews, and healthy recipes. It’s set up similarly to Bodybuilding.com–you can choose workouts based on your training goals and even buy supplements and other related products. Onnit Academy also offers certifications in fitness education, many of which focus on Onnit’s unique training implements.

Onnit Kettlebells

onnit supplements review

For those who want to follow Onnit’s unique training guides for functional strength, it’s possible to buy kettlebells from the company. You can purchase inclusive sets, and you can also find entertaining kettlebells shaped like chimps or Star Wars characters. When buying, you can also purchase starter guides and digital training sessions.

How Do They Do Quality Control?

Onnit is a Certified for Sport company with NSF International. In order to obtain this certification, a company’s production facilities must do the following:

  • Third-party test each batch to make sure what’s on the label is in the bottle
  • Test each batch for unsafe levels of contaminants
  • Test for banned substances and masking agents

Onnit Free Trial Offers

If you aren’t sure if Onnit supplements are for you, you have the opportunity to try some of their best-selling supplements for free.

For most supplements, you can get a free 30-capsule bottle–you’ll just need to pay shipping and handling, which is about $5-12.

Just make sure to cancel the free trial after the 30 days if you don’t want to continue to a subscription!

Final Thoughts

Onnit is an interesting lifestyle brand, and strategic marketing has made it a well-known enterprise. Despite this, many of its products are underwhelming. Many contain ingredients that are supported by little or no research, and their effective ingredients are often included in proprietary blends. Still, there’s a chance one of their products may work for you.
