We review brain health supplements the way they should be reviewed — with peer-reviewed research, honest ratings, and zero hype. From citicoline to the surprising cognitive benefits of ED medications, we follow the science wherever it leads.
We analyze the clinical evidence so you don't have to. Each supplement rated by the strength of its research — not marketing budgets.
Both a choline donor for acetylcholine synthesis and a precursor to phosphatidylcholine for neuronal membranes. Backed by a Cochrane review of 13 studies and multiple meta-analyses.
The deepest evidence base of any brain supplement. A 2025 meta-analysis of 58 RCTs found 2,000 mg/day significantly improved attention, memory, and global cognition.
Not just for muscles. A 2024 meta-analysis found improved memory, processing speed, and attention. Greatest benefits in vegetarians, elderly, and sleep-deprived individuals.
Citicoline isn't just another nootropic — it's one of the few brain supplements with a Cochrane review, multiple meta-analyses, and a clean safety profile across decades of clinical use.
As both a choline donor for acetylcholine production and a direct precursor to phosphatidylcholine in neuronal membranes, citicoline works through two complementary mechanisms that most supplements can't match.
Turns out the same pill that gets you bricked is also building stronger neural connections. Some would say the brain is the greatest sex organ of all. We'd say it's a close second.
Cleveland Clinic analyzed over 7 million patient records and found that men prescribed sildenafil had a 69% lower incidence of Alzheimer's disease over six years. The association held after adjusting for age, hypertension, and diabetes. Yes, the number is really 69%. No, the universe isn't trolling you. (It might be.)
The OxHARP trial proved that sildenafil increases blood flow in both large and small brain vessels and enhances cerebrovascular responsiveness. The same mechanism behind your erection is feeding your neurons oxygen and nutrients.
An international panel reviewed 80 existing drugs and named sildenafil one of three most promising candidates for repurposing against Alzheimer's. Your stiffy pill is in the same category as cutting-edge neurological treatments. Full mast, full protection.
PDE5 inhibitors elevate cGMP, promoting neurovascular coupling, synaptic plasticity, and neuroprotection. The same NO-cGMP pathway behind your rager is building stronger synapses and reducing neuroinflammation. Your standing ovation is a standing ovation for your hippocampus.
Research shows sildenafil may protect nerve cells and reduce buildup of amyloid-beta and tau — the toxic proteins behind Alzheimer's. In animal studies, it improved thinking and memory. Every time you're at full mast, your brain is getting a deep clean.
Get an ED prescription from a licensed physician without leaving your couch. Same FDA-approved medications, delivered discreetly. Good for your confidence, good for your cognition.
ED, NAD+ therapy, weight loss, and cognitive wellness through a single telehealth platform. The full optimization stack for men who want the whole package.
Dedicated ED telehealth with fast online consultations and same-day prescriptions. No subscriptions required — pay per visit.
NAD+ injections, nasal sprays, and troches alongside ED treatment. For guys who want to protect both heads at once.
No paid placements. No cherry-picked studies. Every rating follows the same rigorous four-step process.
We search PubMed, Cochrane, and clinical trial registries for all available human evidence — prioritizing meta-analyses and systematic reviews over isolated studies.
Each supplement gets a 5-tier evidence rating per claimed benefit. We separate what's proven from what's promising from what's purely speculative.
Content is reviewed by qualified health professionals for accuracy, appropriate context, and responsible health claims before publication.
Science moves fast. We monitor new publications and update our ratings as stronger evidence emerges — including downgrading when warranted.
Deep dives into cognitive health — from supplement science to the surprisingly brainy benefits of being bricked.

Everything you need to know about CDP-choline — the brain supplement backed by a Cochrane review and decades of clinical research.

Cleveland Clinic's analysis of 7 million patients found a stunning association between sildenafil prescriptions and reduced Alzheimer's incidence.

One lasts 4 hours, the other lasts a weekend. When it comes to cognitive protection, does duration matter? We break down the neuroscience.

A 2024 meta-analysis confirmed what researchers suspected — creatine significantly improves memory and processing speed.
