Quick Answer: This comparison evaluates three cognitive supplement formulas — Memopryl (GEX Corp, 5 ingredients), Mind Lab Pro (Opti-Nutra, 11 ingredients), and Neuriva (Schiff Nutrition, 2 ingredients) — against four decision-relevant dimensions: ingredient transparency, dose math alignment with research, pricing, and interaction profile. No product received independent testing. All information is sourced from each brand's published materials and verified Supplement Facts panels. Products are presented alphabetically. This comparison includes no affiliate links; it is a traffic-first editorial piece.
How We Evaluated These Cognitive Support Products
This comparison was developed using the DeanSilverMD.com editorial team's standard review methodology: verify the Supplement Facts panel directly before writing, compare ingredient doses against published human clinical research, assess pricing against value delivered by the ingredient stack, and identify the interaction considerations most relevant to the site's primary audience of adults managing complex health decisions.
Products were selected based on market presence, SERP visibility in the cognitive supplement category, and relevance to the reader evaluating Memopryl as a primary product. All three products have substantial organic search presence and represent distinct formula approaches to the cognitive support category — a simple dual-ingredient formula (Neuriva), a focused adaptogenic-botanical formula (Memopryl GEX Corp), and a comprehensive multi-pathway nootropic stack (Mind Lab Pro).
Evaluation dimensions: ingredient transparency (full vs. partial vs. no dose disclosure), dose math alignment (does the formula's dose match the research range for each ingredient?), pricing per day at single-bottle and multi-bottle rates, and interaction profile for the primary audience. No formula received preferential framing. Products are presented alphabetically by brand name, not by outcome quality.
The Comparison Framework — Decision Points That Matter
Evaluating cognitive supplements without a framework produces the same outcome as evaluating nootropics with marketing language: emotionally satisfying, informationally useless. The framework this editorial team applies to every product in this category prioritizes three variables above all others.
First: dose math. An ingredient that appears on a label at one-third the dose studied in published research is not equivalent to the ingredient studied in that research. Full disclosure of milligram amounts per ingredient is the baseline that makes evaluation possible. Products that hide doses behind proprietary blend totals cannot be meaningfully evaluated.
Second: interaction profile. The audience most likely to search for cognitive supplements — adults over 45 managing age-related cognitive complaints — is also the demographic most likely to be taking prescription medications. A formula with strong nootropic credentials but a complex interaction profile may not be the right choice for this population.
Third: pricing in the context of the above. A higher-priced formula with better dose alignment and a cleaner interaction profile may represent better value than a cheaper formula with subtherapeutic doses. The reverse is also true.
Memopryl (GEX Corp) — 5-Ingredient Adaptogenic Formula
The GEX Corp version of Memopryl is the product evaluated in our full anchor review at Memopryl Review 2026. The formula contains five ingredients with fully disclosed milligram amounts: BCAAs 2:1:1 at 540 mg, Bacopa Monnieri Extract at 200 mg, Rhodiola Rosea Extract (3% Salidroside) at 100 mg, L-Theanine at 100 mg, and Panax Ginseng Extract at 90 mg.
Ingredient transparency: full disclosure, all five ingredients with milligram amounts. Dose math: Bacopa at 200 mg is within the lower range of published research (most trials used 300-450 mg). Rhodiola at 100 mg standardized to 3% salidroside is within published human fatigue trial ranges. L-Theanine at 100 mg aligns with standalone attentional research. Panax Ginseng at 90 mg is below the 200-400 mg range most studied in cognitive trials. BCAAs at 540 mg are well-dosed for nutritional purposes; cognitive-specific research base is thin.
Pricing: $49-$79 per bottle (30-day supply) depending on package. Per-day cost ranges from approximately $1.63 (6-bottle) to $2.63 (2-bottle). Free shipping on 3- and 6-bottle orders.
Interaction profile: moderate. Panax Ginseng warrants caution for anticoagulant and diabetes medication users. Bacopa warrants attention for thyroid conditions and sedative medications. Rhodiola has blood pressure medication considerations. L-Theanine is the lowest-risk ingredient. Full interaction detail is in our Cognitive Supplement Safety Guide.
Formula focus: stress-related cognitive fatigue and gradual memory support. Best suited for adults managing cognitive demands in high-stress environments rather than those seeking direct neurochemical enhancement. No stimulants.
Mind Lab Pro (Opti-Nutra) — 11-Ingredient Comprehensive Stack
Mind Lab Pro is an 11-ingredient formula manufactured by Opti-Nutra and positioned as a “universal nootropic” targeting multiple cognitive pathways simultaneously. All ingredient doses are fully disclosed on the label, which is the baseline that makes meaningful evaluation possible. Key ingredients include Citicoline at 250 mg, Phosphatidylserine (from sunflower lecithin) at 100 mg, Bacopa Monnieri at 150 mg (standardized to 45% bacosides), Lion's Mane Mushroom fruiting body at 500 mg, N-Acetyl-L-Tyrosine at 175 mg, L-Theanine at 100 mg, Rhodiola Rosea at 50 mg (standardized to 3% rosavins and 1% salidroside), and Maritime Pine Bark Extract at 75 mg.
Dose math: Bacopa at 150 mg, while standardized to 45% bacosides, is below the dose range most studied in human memory trials (300-450 mg). Phosphatidylserine at 100 mg is below the 300 mg dose used in most trials with significant outcomes. Lion's Mane at 500 mg of fruiting body is within the range studied for nerve growth factor support. Citicoline at 250 mg is within studied ranges for working memory support. Rhodiola at 50 mg is below the ranges used in published fatigue trials.
Pricing: approximately $65-$70 per bottle (30-day supply), with per-day cost of approximately $2.17-$2.33. Discounts available on multi-bottle purchases direct from brand.
Interaction profile: more complex than Memopryl due to greater ingredient breadth. Rhodiola and Maritime Pine Bark (which has some anticoagulant-relevant effects) add to the interaction checklist. No St. John's Wort. Lion's Mane has a low interaction profile. The overall complexity warrants a medication review for adults on prescriptions, though no single ingredient carries as high an individual interaction signal as St. John's Wort would in other formulas.
Formula focus: multi-pathway — simultaneously targets cerebral blood flow (Maritime Pine Bark), acetylcholine support (Citicoline), membrane integrity (Phosphatidylserine), nerve growth (Lion's Mane), memory (Bacopa), stress adaptation (Rhodiola), and neurotransmitter precursor availability (L-Tyrosine). Broader than Memopryl GEX Corp by design.
Neuriva (Schiff Nutrition) — 2-Ingredient Simplified Formula
Neuriva is a two-ingredient cognitive supplement manufactured by Schiff Nutrition (a Reckitt company). The formula contains Phosphatidylserine at 100 mg (from sunflower lecithin) and Coffee Fruit Extract (NeuroFactor) at 100 mg. Both doses are fully disclosed. The product is available widely at major pharmacy and retail chains.
Dose math: Phosphatidylserine at 100 mg is below the 300 mg dose used in most human clinical trials showing significant cognitive outcomes. This is the primary dose math limitation. Coffee Fruit Extract (NeuroFactor) has preliminary research on BDNF (brain-derived neurotrophic factor) elevation, with a 2013 pilot study by Reyes-Izquierdo et al. in the British Journal of Nutrition finding elevated plasma BDNF at the 100 mg dose — the same dose used in Neuriva. The cognitive outcome implications of BDNF elevation through this pathway are still being studied; this is promising early research, not established clinical evidence.
Neuriva has published proprietary clinical trials on its formula showing modest improvement in specific cognitive measures including memory and focus scores over 5 weeks. Study durations were shorter than the 12-week threshold Bacopa research suggests for reliable effects, limiting direct comparison. The trials are available through the brand's website.
Pricing: approximately $25-$50 per bottle (30-day supply) at major retailers, with per-day cost of approximately $0.83-$1.67 depending on retailer and variant. The most accessible price point of the three products.
Interaction profile: lowest of the three products in this comparison. Phosphatidylserine and Coffee Fruit Extract have documented interaction concerns primarily with blood thinners at higher doses and potential caffeine-related considerations with the coffee-derived ingredient (though NeuroFactor is decaffeinated). The two-ingredient simplicity significantly shortens the medication review checklist.
Formula focus: simplified daily cognitive maintenance. Best suited for adults who want a low-complexity, low-interaction-risk entry point into cognitive supplementation without committing to a complex multi-ingredient formula.
Side-by-Side: The 4 Decision Points
Ingredient transparency: All three products disclose doses for all active ingredients — a meaningful baseline that distinguishes them from proprietary blend competitors. Mind Lab Pro's 11-ingredient stack provides the most information but also requires the most evaluation time. Memopryl GEX Corp's 5-ingredient panel is faster to evaluate. Neuriva's 2-ingredient transparency is the simplest.
Dose math alignment: No formula in this comparison hits the research-optimal range for every ingredient. Mind Lab Pro's Bacopa (150 mg) and Phosphatidylserine (100 mg) are both below most-cited research doses. Memopryl GEX Corp's Bacopa (200 mg) is closer to the low end of the research range; its Ginseng (90 mg) is below. Neuriva's Phosphatidylserine (100 mg) is below. Each formula makes tradeoffs between ingredient breadth and individual ingredient dose.
Pricing: Neuriva is the most affordable at major retail. Memopryl GEX Corp occupies a mid-range position with competitive multi-bottle pricing. Mind Lab Pro is the most expensive of the three on a per-day basis. Value assessment depends on which ingredient profile best matches your needs — higher price with broader stack coverage vs. lower price with a more focused formula.
Interaction profile: Neuriva presents the lowest interaction risk. Memopryl GEX Corp is moderate, with Panax Ginseng and Bacopa as the primary consideration points. Mind Lab Pro is moderate to moderately complex, with the broader ingredient list creating a longer but individually lower-signal interaction checklist.
Which Formula for Which Situation
For the adult managing stress-related cognitive fatigue who wants a caffeine-free adaptogenic formula at a mid-range price point: The GEX Corp Memopryl formula's adaptogenic backbone — Rhodiola Rosea and Panax Ginseng alongside Bacopa — addresses the stress-fatigue mechanism most directly. This is the formula most relevant to the large segment of adults whose cognitive complaints center on afternoon fog, difficulty concentrating under pressure, and mental energy depletion rather than acute memory failure. Its 60-day refund policy provides a meaningful trial window.
For the adult who wants the broadest multi-pathway nootropic coverage and is not on prescriptions: Mind Lab Pro's 11-ingredient formula covers more mechanisms simultaneously — cerebral blood flow, acetylcholine, membrane integrity, nerve growth, and stress adaptation. The higher price reflects that breadth. The interaction checklist is longer by necessity. Adults not on prescription medications who want a comprehensive daily nootropic stack will find Mind Lab Pro covers more ground than either alternative.
For the adult managing multiple medications who wants the lowest interaction risk profile and widest retail access: Neuriva's two-ingredient simplicity makes it the easiest to screen against a medication list. It is available at pharmacies without a special order. The trade-off is the thinnest evidence base of the three and the lowest ingredient breadth. It functions best as a low-commitment entry point or as a supplementation option for adults whose prescribing physician has cleared the two ingredients specifically.
Readers considering any of these formulas are encouraged to review our overview of how memory consolidation works and our adaptogen and nootropic research overview before making a purchase decision — understanding the biology that supplements attempt to support is the most useful context for evaluating whether any of them fits your situation.
Frequently Asked Questions
Which cognitive supplement has the most transparent ingredient list? All three products in this comparison disclose doses for all active ingredients. Mind Lab Pro discloses doses for all 11 ingredients. Memopryl GEX Corp discloses all five. Neuriva discloses both. Transparency enables dose math — the practice of comparing a product's doses against research literature — which is the most practically useful tool for supplement evaluation. Products that conceal doses behind proprietary blend totals cannot be meaningfully evaluated by this standard.
Is Mind Lab Pro better than Memopryl? Neither is universally superior — they address different aspects of cognitive support with different formula approaches. Mind Lab Pro offers broader multi-pathway coverage at a higher price. GEX Corp Memopryl offers a focused adaptogenic approach at a mid-range price. The right formula depends on which cognitive mechanisms you are prioritizing and which interaction profile is appropriate for your health situation. Our Memopryl review covers the GEX Corp formula in detail for direct reference.
Is Neuriva worth it? Neuriva's value depends on what you are optimizing for. If lowest interaction risk and widest retail access are the priorities, it delivers on both. If dose alignment with clinical research is the priority, its Phosphatidylserine at 100 mg is below the range used in most outcome-significant trials. Its proprietary clinical research is published but short-duration compared to the 12-week threshold Bacopa research identifies as necessary for reliable effects.
