Alpha Brain
Alpha Brain by Onnit is a nootropic formula that may support healthy brain function. It could help maintain mental energy, clarity, and basic cognitive processes like thinking, learning, and decision-making.
The formula includes huperzia serrata extract (providing Huperzine A), which is known to inhibit the breakdown of acetylcholine neurotransmitter involved in memory and learning.
Alpha GPC is a choline compound that may support the production of acetylcholine and overall brain cell communication. The makers also added vitamin B6 to the Alpha Brain, which may support neurotransmitter synthesis, supporting proper cognitive function and mood regulation. It also combines phosphatidylserine, which is a phospholipid present in brain cell membranes that may help maintain cellular function and communication.
As per the official website, Alpha Brain has l-theanine, which may support relaxation without making you feel tired and modulate neurotransmitter activity related to focus and attention. It could support memory, learning, attention, and overall cognitive processes.

Total Human
Onnit claims that its Total Human is a supplement system containing separate Day and Night Packs intended for daily use.
The Day Pack contains Alpha Brain, Shroom Tech Sport, strontium, boron, manganese, and a methylated B Complex. Alpha Brain supports memory, focus, and cognitive performance by providing nutrients that enhance neurotransmitter activity and brain function.
Shroom Tech Sport contains functional mushrooms like Cordyceps and Reishi, which may improve endurance, energy production, and exercise performance by supporting mitochondrial function and reducing fatigue.
This formula also contains strontium, which might help strengthen bones by supporting bone mineral density, while boron might aid in bone health and hormone regulation. Manganese is essential for bone formation, connective tissue health, and antioxidant enzyme function.
The methylated B Complex provides bioavailable B vitamins that support cellular energy production, nervous system function, and your body’s response to stress, helping you stay alert and energized throughout the day.
The Night Pack in the Total Human contains New Mood (Valerian root, 5-HTP, L-tryptophan), vitamin C, zinc, selenium, and additional minerals. Valerian root has calming properties that may help relax the nervous system and boost sleep quality. This pack also has 5-HTP and L-tryptophan, which are precursors to serotonin, supporting mood regulation and promoting restful sleep. Vitamin C in this formula may aid in cell repair, collagen synthesis, and immune support, while zinc supports immune function, wound healing, and DNA synthesis.
Several ingredients appear in both packs, including Shroom Tech Immune, krill oil (providing EPA, DHA, and astaxanthin), spirulina, and chlorella.
Shroom Tech Immune combines medicinal mushrooms to support immune system health and reduce inflammation. Krill oil may provide omega-3 fatty acids EPA and DHA, which promote cardiovascular and brain health, while astaxanthin offers strong antioxidant protection.
Spirulina and chlorella are nutrient-dense algae that provide essential vitamins, minerals, and antioxidants, support detoxification, and contribute to joint and cellular health. These shared ingredients could strengthen wellness, protect against oxidative stress, and support long-term vitality.

Rigorous Batch Testing
Onnit highlights that all its supplements are produced in NSF-certified GMP facilities in the U.S., adhering to strict FDA 21 CFR 111 standards. It mentions that each batch is tested for label accuracy, product specifications, heavy metals, and microbial contamination, with third-party verification to ensure purity and potency.
Onnit also claims to use research-backed ingredients like organic prebiotics for gut health, seven probiotic strains, adaptogens such as ashwagandha, and nootropics like Alpha-GPC and Cognizin to support brain function, energy, sleep, digestion, and performance.

Onnit Limitation
Absence Of A Formal Scientific Advisory Board
Onnit promotes its supplements as being made with “science-backed ingredients” and “rigorously tested,” but the brand does not provide details of a formal Scientific Advisory Board with named experts or credentials. Without knowing who is providing independent oversight, you have no clear way of verifying whether qualified professionals support product claims. This lack of transparency makes it harder to fully trust the scientific credibility of what you’re buying. The absence of a formal, visible board also impacts your trust and accountability for the brand. Without independent researchers or clinicians publicly tied to Onnit, the company’s scientific process can appear more marketing-driven than evidence-based. This means you’re relying mainly on the brand’s own assurances rather than verified expert review.
Pros
- Offers a comprehensive range of supplements targeting cognition, mood, energy, and performance.
- The brand claims that its products are made in facilities compliant with GMP standards.
- It offers products in various forms, including capsules, powders, and gummies.
Cons

How Did We Evaluate Onnit?
-
Brand Credibility
Onnit is based in Austin, Texas, and positions itself as a lifestyle and supplement brand with a focus on fitness, nutrition, and cognitive health.
Over the past decade, it has gained visibility through collaborations with athletes, fitness influencers, and podcasts.
Its product range spans supplements like Alpha Brain, functional foods, fitness equipment, and wellness programs designed to support both mental and physical performance.
To form our evaluation, we looked at the brand’s history, background, and customer reputation. While Onnit has strong market visibility and over a decade of experience, consumer feedback paints a different picture. The company currently holds a D- rating on the Better Business Bureau and averages 1.5 stars on Trustpilot across more than 15,000+ reviews. Common complaints cite issues with customer service, fulfillment, and product satisfaction. This contrast between brand presence and customer experience weighed heavily in our assessment, highlighting credibility challenges despite Onnit’s established name in the industry.
-
Real Consumer Feedback
To evaluate Onnit, we closely reviewed customer feedback posted on Trustpilot between 2024 and 2025. These reviews highlighted consistent patterns across years, allowing us to assess both the brand’s strengths and its recurring challenges.
Customers repeatedly described negative experiences. In late 2024, one reviewer reported having their account locked after a simple billing address error, with no clear explanation or timely support.
Other customers were still reporting similar frustrations, such as unresolved support tickets, unresponsive communication, and slow resolutions to shipping issues like damaged or lost orders. This continuity of complaints points to systemic issues in customer service and account management.
Marketing practices also weighed heavily in our evaluation. A review detailed how Onnit promoted “limited edition” products with urgency-driven advertising, only to re-release them later without the promised scarcity.
Customers described this as manipulative and misleading, with some overpaying on resale markets under the false impression of exclusivity. These reviews raise serious concerns about the brand’s transparency and respect for its customer base.
Product effectiveness produced mixed opinions across the years. Some customers expressed satisfaction with Alpha Brain supplements, noting a clear impact.
On the other hand, other reviews called the products ineffective or even labeled the experience a scam. This inconsistency shows that while some users find value, many others feel let down by the results.
Balancing these perspectives, our evaluation suggests that operational and credibility challenges overshadow Onnit’s visibility and reputation in the wellness space. The Trustpilot feedback reflects repeated frustrations with customer service, fulfillment reliability, and marketing ethics. These factors significantly influenced our assessment, showing that while Onnit has strong name recognition, its customer experience and trustworthiness remain in question.

Onnit focuses on making supplements that can aid in cognitive function, physical performance, and energy. Its formulations emphasize evidence-based ingredients, including adaptogens, nootropics, and probiotics, reflecting a holistic approach to mental and physical health. The brand highlights transparent labeling, structured supplementation systems, and quality control measures to help you make informed choices.
