Read the Saffron report →Glycine anxiety earns 6.5/10 because Soh 2024 anchors the most relevant signal. Glycine fits anxiety because glycine participates in sleep signaling, glutathione, collagen, methylation, and nervous-system balance, depending on the endpoint. The…
Read the Glycine report →The anxiety use case earns 6.5/10 for Vagus Nerve Stimulation, anchored by Sun et al. 2025. Autonomic rebalancing could support anxiety symptoms; depression and insomnia trials show anxiety-adjacent improvements, but anxiety-specific tVNS…
Read the Vagus Nerve Stimulation report →The anxiety case for Selank is 6.5/10 because Kasian 2017 reports Rat stress model; individual and combined Selank plus diazepam arms. Zozulia 2008 points in the same direction, but route, dose, baseline…
Read the Selank report →Anxiety is the best-supported consumer use at 6.4/10. In Bergamaschi 2011, a double-blind RCT, a single 600 mg dose of CBD significantly reduced anxiety, cognitive impairment, and discomfort during a simulated public-speaking…
Read the Full-Spectrum Hemp (CBD) report →The anxiety case for Taurine is 6.0/10 because Zhang 2007 reports Mechanistic in vivo anxiety model supporting glycine receptor pathway. The score stays conditional because Taurine still needs better outcome data for…
Read the Taurine report →Melatonin has a real but context-specific anxiety signal around surgery. A Cochrane review on preoperative and postoperative anxiety found melatonin can reduce preoperative anxiety compared with placebo, while postoperative findings were less…
Read the Melatonin report →Bromantane carries an explicit anxiolytic limb confirmed in the only placebo-controlled human RCT, where Neznamov 2009 characterized the drug as combining psychostimulant and anxiolytic actions in neurasthenia patients. The Voznesenskaia 2010 multicenter…
Read the Bromantane (Ladasten) report →Zone 2 Cardio earns 5.5/10 for anxiety because Vabishchevich 2026 is the cleanest verified anchor for this report. The existing rationale points to this narrower claim: Zone 2 can lower anxiety by…
Read the Zone 2 Cardio report →Anxiety and obsessive-compulsive symptoms score 5.5/10 on the OCD-adjunct data. Afshar 2012 (n=48) found NAC add-on improved Y-BOCS scores significantly (52.6 percent responders versus 15 percent on placebo) in treatment-refractory OCD over…
Read the NAC (N-Acetylcysteine) report →Lion's Mane anxiety earns 5.5/10 because Nagano 2010 anchors the most relevant signal. Lion's Mane fits anxiety when the goal is gentle mushroom-based support for cognition, mood, nerve biology, or gut-immune signaling…
Read the Lion’s Mane report →Current evidence gives Whole-Body Vibration a 5.0/10 rating for anxiety, because no direct clinical trials have measured anxiety outcomes. The only relevant data come from broad anti-inflammatory meta-analyses such as Wang et…
Read the Whole-Body Vibration report →Apigenin earns 5.0/10 for anxiety because Amsterdam 2009 and Mao 2016 support chamomile extract for generalized-anxiety symptoms, with Apigenin as one likely contributor. The score stays moderate because these trials did not…
Read the Apigenin report →For anxiety, Ca-AKG (Calcium Alpha-Ketoglutarate) lands at 5.0/10 because Filip 2007 supports the strongest part of the claim. The existing rationale points to this narrower claim: No direct evidence. Any anti-inflammatory mood…
Read the Ca-AKG (Calcium Alpha-Ketoglutarate) report →Aniracetam scores 5.0/10 for anxiety because the most cited anxiolytic case rests on animal and mechanism work rather than human anxiety trials. The strongest support comes from Isaacson et al. 1991, but…
Read the Aniracetam report →Anxiety remains 5.0/10 because Semaglutide can quiet food noise for some users while creating anxiousness, nausea vigilance, or reward flattening for others. Wilding 2021 supports the weight-loss mechanism, but not an anxiolytic…
Read the Semaglutide report →Tirzepatide has no anxiety specific RCT. Some users may feel better through weight loss, sleep gains, reduced food noise, and metabolic control. Others may feel worse from nausea, under eating, body image…
Read the Tirzepatide report →Aerobic exercise is often anxiolytic, but near-max intervals can feel panic-like for some users early on. A beginner progression and nasal breathing during recovery can improve tolerability.
Read the Norwegian 4×4 report →No direct anxiety evidence was verified for EAA supplementation. Avoid implying a psychiatric benefit.
Read the Essential Amino Acids report →Anxiety scores 4.5/10. Post-sauna relaxation and parasympathetic rebound plausibly ease anxiety for some users, and pooled wellbeing data is supportive, but there is no anxiety-specific traditional-sauna trial. This is a modest, mechanism-and-report…
Read the Traditional Sauna (Finnish Dry-Heat) report →HPA-axis modulation is relevant to anxiety, and Hellhammer 2004 supports reduced endocrine stress response. There are no dedicated anxiety-disorder RCTs, so the score stays modest.
Read the Phosphatidylserine report →Anxiety support is inferred from stress-hormone and POMS data rather than anxiety-specific trials. Tongkat Ali can also feel activating, so anxious users may worsen if dosing is too high or too late.
Read the Tongkat Ali report →No direct anxiety evidence supports metformin. Any anxiety change would be indirect through glycemic stability, body composition, or side-effect burden.
Read the Metformin report →INSUFFICIENT_EVIDENCE for anxiety treatment; off-label surveys and PEARL well-being signals are uncontrolled or secondary.
Read the Rapamycin report →Anxiety stays at 4 because v0 GABAergic and anxiolytic framing is based on preclinical work and review summaries, not human psychiatric trials. Pickart 2018 mentions anti-anxiety activity, but clinical evidence is weak.
Read the GHK-Cu report →Anxiety evidence is weaker than depression evidence. Some meta-analytic signals exist, but heterogeneity and endpoint inconsistency keep this below the practical threshold for a strong use case.
Read the Omega-3 report →Anxiety response is mixed. Some hypogonadal men feel calmer once energy and libido improve, while others get irritability, sleep disruption, or sympathetic activation from dose peaks. Evidence is too thin for a…

Head-to-head reports and category rankings that name a winner on this use case.
Bromantane and semax tie at 7.1, and they are the only two in this category scored strong recommend. Selank is third at 6.9 if anxiety rather than focus…
Melatonin, dosed low. It scores 8.2 against apigenin's 6.7 and wins the sleep rows outright. The morning hangover apigenin markets against comes from taking too much, not from…
Both score anxiety 7.5, so the tie-breaker is time. L-theanine works in about an hour and you take it when you need it. Ashwagandha takes eight weeks and…
Bromantane, for anything you plan to repeat. It scores 7.1 against phenylpiracetam's 5.5 and wins every shared use case that is not a floor tie: energy 6.2 to…
Neither, yet. Both have zero human trials, zero human pharmacokinetics and research-only access. PE-22-28 scores 4.9 and dihexa 4.4, and the gap is entirely safety: dihexa potentiates the…
They solve different problems and the scores hide that. Oxytocin scores 6.5 against PT-141's 5.4, mostly on safety and cost. PT-141 still wins libido 5.5 against 2.5. Oxytocin…
Shilajit scores 7.4 and ashwagandha 6.8, but that gap is the least useful number here. These two do different jobs. Shilajit is the mineral and androgen play: male…
Ashwagandha scores 6.8 and tongkat ali 7.0, so the overall numbers do not decide it. Pick ashwagandha when stress, anxiety, or sleep is the complaint: its subratings there…
Bromantane scores 7.1 and modafinil 5.9, and they answer different questions. Modafinil is the faster and better-documented wakefulness drug when sleep debt or diagnosed sleepiness is the problem.…
Magnesium, if the problem is sleep quality. It scores 8.7 against melatonin's 8.2 and leads sleep-quality 8.6 to 7.1, with a larger measured cut to sleep latency. Melatonin…
Pick by symptom. Semax scores 7.1 and wins focus. Selank scores 6.9 and wins anxiety, mood and stress resilience. The 0.2 gap decides nothing. The mechanisms overlap at…
HRV Biofeedback, at 8.0 out of 10 for anxiety. The anxiety use case earns 8.0/10 for HRV Biofeedback, anchored by Eddie et al.
Of the top-scoring options, Glycine is the least expensive at about $2 a month, scoring 6.5 out of 10 for anxiety.
