Quick Answer: This comparison evaluates four brain health supplements — Mind Lab Pro, Memopryl, Neuriva, and Prevagen — against five consistent criteria: ingredient transparency, research quality, drug interaction profile, kidney-specific safety considerations, and price-to-value ratio. Memopryl is notable for containing St. John's Wort, which has clinically documented interactions with kidney transplant immunosuppressants. Mind Lab Pro offers the most dosage transparency and the only finished-product clinical data in this group. No supplement in this comparison has been studied in CKD populations.
How We Evaluated These Brain Health Supplements
This comparison evaluates four products in the nootropic brain supplement space against consistent criteria. Products were selected based on SERP presence in the Memopryl search category, reader relevance to the kidney-conscious audience on this site, and market visibility in the 2026 brain supplement landscape. We also reviewed Neuriva separately on this site, and that review is available for additional context.
Each product was evaluated against the same five dimensions: ingredient transparency (are individual mg amounts disclosed?); research quality (what does the peer-reviewed literature say about the ingredients?); drug interaction profile (what prescription medications interact with these ingredients?); kidney-specific safety considerations (does anything in the formula warrant extra caution for CKD or transplant patients?); and price-to-value ratio (cost per day relative to what the formula delivers).
No independent product testing was conducted. All information is sourced from each brand's published materials, available Supplement Facts panels, and published pricing as of May 2026. This site does not accept payment from supplement brands for editorial placement. This comparison includes no affiliate relationships in its current traffic-first publication state.
Products are ordered alphabetically. The product this site has reviewed separately is not placed first as a matter of editorial policy, consistent with our commitment to non-promotional comparison methodology.
The Comparison Framework: Decision Points That Matter
Brain supplement marketing tends to compete on ingredient lists and marketing claims. For most readers, and particularly for kidney-conscious readers, five factors matter more than any marketing claim. Ingredient transparency determines whether a buyer can compare a product's doses to research doses. Research quality determines whether the ingredients chosen have genuine human clinical data. Drug interaction profile determines whether the supplement is safe alongside existing prescriptions. Kidney-specific considerations identify any formula features that warrant extra caution for this audience. And price-to-value ratio determines whether the formula justifies the cost relative to alternatives.
Each product below is evaluated against all five. No product in this comparison excels on all five.
Mind Lab Pro
Mind Lab Pro is a multi-ingredient nootropic supplement manufactured by Performance Lab Group. It contains 11 active ingredients with fully disclosed individual dosages, including Citicoline (250 mg), Bacopa Monnieri (150 mg standardized to 24% bacosides), Lion's Mane Mushroom (500 mg), Phosphatidylserine (100 mg from sunflower lecithin), N-Acetyl-L-Tyrosine, L-Theanine, Rhodiola Rosea, Maritime Pine Bark Extract, and B vitamins (B6, B9, B12). The brand has published two peer-reviewed human clinical studies on the finished Mind Lab Pro formula — a structural advantage over most competitors in this category.
Ingredient transparency is a notable strength: full disclosure enables buyers to compare each ingredient's dose to the research literature. Bacopa at 150 mg is below some research doses (300–450 mg range), and Phosphatidylserine at 100 mg is below the 300 mg used in most cited trials — transparency gaps that are present in the formula, but at least visible to the buyer. Mind Lab Pro does not contain St. John's Wort. Drug interaction concerns include potential interactions between some botanical extracts (Rhodiola Rosea, Maritime Pine Bark) and blood pressure or anticoagulant medications — less clinically documented than St. John's Wort interactions but worth disclosing to a pharmacist.
Price: approximately $2.30 per day at single-bottle pricing; lower at multi-bottle packages. Not sold on Amazon by the brand; official website direct.
Memopryl
Memopryl is an 8-ingredient nootropic supplement distributed by MemoPryl Research and sold through ClickBank. The formula contains Ginkgo Biloba Extract, Phosphatidylserine, Bacopa Monnieri Extract, N-Acetyl-L-Carnitine (ALCAR), St. John's Wort, L-Glutamine, Alpha-GPC, and Huperzine A. Per-ingredient mg dosages are not publicly disclosed — the Supplement Facts panel is available only on the physical product label.
The research quality of the individual ingredients is genuine: Bacopa, Phosphatidylserine, and Alpha-GPC each have peer-reviewed human clinical data. No randomized controlled trial on the finished Memopryl formula has been published. The cholinergic triple-stack (Alpha-GPC, ALCAR, Huperzine A) is the most structurally notable feature of this formula — multiple cholinergic-pathway ingredients in combination — and is relevant for anyone on prescription medications affecting the same system.
The kidney-specific concern is St. John's Wort. Peer-reviewed pharmacology literature, including Nicolussi et al. (2020) in the British Journal of Pharmacology, documents CYP3A4 induction by St. John's Wort compounds that can substantially reduce blood levels of cyclosporine and tacrolimus — medications kidney transplant patients depend on. This is the highest-priority safety note for this site's audience and is addressed in full in our Memopryl review and our kidney patient safety guide.
Pricing ranges from $49 to $79 per bottle ($0.82 to $2.63 per day) depending on package. 60-day refund policy requires return of all bottles including empties. Contact: [email protected].
Neuriva
Neuriva is a brain health supplement manufactured by Reckitt (under the Schiff Vitamins brand) and widely available in pharmacies and retail stores. The formula is transparent and simple: two active ingredients with disclosed dosages — phosphatidylserine (100 mg) and coffee fruit extract (NeuroFactor, 100 mg). Multiple product variants exist (Original, Plus, Ultra) with varying additional ingredients including B vitamins in some formulations.
Ingredient transparency is Neuriva's structural strength relative to Memopryl: all active ingredient amounts are disclosed. The trade-off is formula depth. Phosphatidylserine at 100 mg is below the 300 mg research dose. Coffee fruit extract has preliminary data on BDNF elevation but limited cognitive outcome research in humans. Neuriva has published proprietary trials on its formula showing modest cognitive improvements, though study durations were shorter than the 12-week threshold Bacopa research identifies as necessary for measurable effects.
Kidney-specific considerations: Neuriva's formula does not contain St. John's Wort, and its two-ingredient simplicity means a shorter interaction checklist. It does contain soy lecithin as a Phosphatidylserine source — relevant for soy-sensitive individuals. Drug interaction profile is low relative to the other products in this comparison. We reviewed Neuriva separately for this site and that evaluation is available here for readers who want ingredient-level detail.
Pricing: approximately $1.10 to $1.67 per day depending on variant. Available at major retailers and Amazon. 30-day return policy applies to unopened bottles in standard retail channels.
Prevagen
Prevagen is manufactured by Quincy Bioscience and is one of the most heavily advertised brain supplements in the United States. Its primary active ingredient is apoaequorin — a calcium-binding protein originally derived from bioluminescent jellyfish. The formula is simple: apoaequorin at 10 mg per capsule, with vitamin D added.
Research quality is the weakest in this comparison. Quincy Bioscience's own clinical trial of Prevagen found no statistically significant improvement in its primary outcomes. The FTC and New York Attorney General filed a joint lawsuit in 2017 challenging Prevagen's advertising claims. Independent researchers have questioned whether orally ingested apoaequorin survives the digestive process intact, as proteins of this size are typically broken down into amino acids in the gut. Prevagen has been transparent about its ingredient and dosage — but the ingredient itself has not cleared the evidentiary bar that Bacopa, Phosphatidylserine, or Alpha-GPC have established.
Kidney-specific considerations: Prevagen does not contain St. John's Wort, botanicals with notable mineral content, or cholinergic agents. Its interaction profile is lower than others in this comparison. If a CKD patient is seeking a brain supplement with the lowest drug interaction risk profile among these four, Prevagen's formula is structurally simpler — though its efficacy evidence is correspondingly weaker.
Pricing: approximately $1.33 to $2.00 per day for regular and extra strength variants. Available at major pharmacies and retailers.
Side-by-Side: The Five Decision Points
Ingredient transparency: Mind Lab Pro and Neuriva fully disclose individual dosages. Prevagen discloses its one active ingredient dose. Memopryl does not publicly disclose per-ingredient mg amounts.
Research quality: Mind Lab Pro has the strongest overall evidence base, including a finished-product clinical study. Bacopa (in Memopryl and Mind Lab Pro) and Phosphatidylserine (in all four products) have the most consistent ingredient-level research. Prevagen's apoaequorin has the weakest evidence base in this group.
Drug interaction profile: Memopryl carries the most complex interaction profile due to St. John's Wort and the cholinergic triple-stack. Mind Lab Pro's 11 ingredients create more potential interactions than Neuriva's 2, though none carry the same documented clinical risk as St. John's Wort for transplant patients. Prevagen and Neuriva carry the lowest interaction complexity in this group.
Kidney-specific safety: St. John's Wort in Memopryl is the highest-priority concern for kidney transplant patients specifically. For general CKD patients, all four products require nephrologist review before use. None have been studied in CKD populations.
Price-to-value: Memopryl's 6-bottle pricing ($0.82/day) represents the lowest per-day cost in this group. Mind Lab Pro's multi-bottle pricing ($1.73/day) offers strong value given ingredient disclosure and finished-product research. Neuriva ($1.10/day) is the most accessible price point with full transparency. Prevagen ($1.33–$2.00/day) prices higher than its evidence base justifies relative to competitors.
Which Formula for Which Situation
For kidney transplant patients: None of these four products should be started without explicit clearance from your transplant nephrologist. The transplant team's guidance supersedes any recommendation in this comparison. If a transplant patient's nephrology team does provide clearance for a supplement, Neuriva or Prevagen offer simpler ingredient profiles without St. John's Wort. This is not an endorsement — it is a relative risk observation.
For CKD patients on multiple medications: Bring the full Supplement Facts panel of any product you're considering to your nephrologist or pharmacist for a drug interaction review. Among these four, Neuriva's two-ingredient formula is easiest to review quickly. Memopryl's 8-ingredient formula — with St. John's Wort — creates the longest checklist for any patient on prescription medications.
For generally healthy adults prioritizing ingredient transparency: Mind Lab Pro offers the most complete picture — 11 disclosed dosages and finished-product clinical data. It is the highest price point, but the buyer can compare every ingredient dose to the research literature. Neuriva is a solid second choice for transparency in a simpler, lower-dose formula.
For generally healthy adults seeking the lowest cost-per-day in this comparison: Memopryl at the 6-bottle price point offers the lowest per-day cost among these four products. The trade-off is dosage non-disclosure, no finished-product clinical data, and the St. John's Wort interaction consideration. For buyers who are not on contraindicated medications, that trade-off may be acceptable; for buyers on prescription medications, the interaction profile requires physician review before purchase.
For older adults with significant memory concerns: Memory concerns that affect daily function are a clinical question, not a supplement question. None of these four products has been approved for or studied as a treatment for Alzheimer's disease, dementia, or mild cognitive impairment. A physician or neurologist evaluation is the appropriate first step.
Frequently Asked Questions
Which brain supplement is safest for CKD patients? No brain supplement can be recommended as categorically safe for all CKD patients. Prevagen and Neuriva have simpler interaction profiles than Memopryl or Mind Lab Pro relative to typical CKD medications, but all four require nephrologist or pharmacist review before use by kidney patients. Individual kidney stage, eGFR, and current medication list are the determining factors.
Is Mind Lab Pro better than Memopryl? On ingredient transparency (disclosed dosages vs. undisclosed), finished-product clinical data (Mind Lab Pro has it; Memopryl does not), and drug interaction profile for prescription medication users (Mind Lab Pro has no St. John's Wort), Mind Lab Pro has structural advantages in this comparison. On per-day cost at the best-value price tier, Memopryl is lower. Neither has been studied in CKD populations.
Does Neuriva work for memory? Neuriva has conducted proprietary trials showing modest cognitive improvements over placebo. Its Phosphatidylserine dose (100 mg) is below the 300 mg used in most supporting research. Coffee fruit extract's BDNF-related findings are preliminary. Individual results vary and expectations should be modest relative to marketing language.
