Which active ingredients in Memory Blast cross the blood-brain barrier in humans?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
The available reporting identifies Ginkgo biloba as the only explicit active named on Memo Blast’s marketing pages, but the sources supplied do not provide peer‑reviewed human pharmacokinetic data showing which of Memo Blast’s active ingredients (if any beyond the single named extract) physically cross the human blood–brain barrier (BBB) [1] [2]. Broader literature cited in the reporting shows that some classes of natural compounds (certain polyphenols, alkaloids and specialized molecules such as alpha‑GPC, huperzine A, or magnesium L‑threonate) can cross the BBB in humans or animal models, yet the presence of those specific, BBB‑crossing actives inside Memo Blast is not established by the provided sources [3] [4] [5].
1. What the product claims — manufacturer’s framing vs. the evidence available
Memo Blast’s official pages promote a “clinically researched nootropic” blend and repeatedly name Ginkgo biloba as a cornerstone ingredient that “improves blood circulation in the brain” and supports cognition [1] [2]; those manufacturer statements are marketing claims present in the supplied sources [1] [2]. The company pages assert brain blood‑flow and neurotransmitter benefits but do not publish a full ingredient list in the material provided here nor primary studies demonstrating which ingredient molecules achieve measurable central nervous system levels in humans [1] [2].
2. What independent science in the reporting says about natural compounds that can cross the BBB
Review articles and databases in the supplied reporting emphasize that some natural product classes — terpenoids, polyphenols, and certain alkaloids — have been shown by in vitro, in vivo and computational work to have moderate to high BBB permeability, while many others do not [3]. Specific examples cited in the reporting include anthocyanins from berries as polyphenols that can cross the BBB and influence neuronal function [6], and established supplement molecules such as alpha‑GPC and huperzine A being described in other sources as capable of entering the brain [4].
3. Ingredients frequently asserted to cross the BBB — and whether Memo Blast contains them
Outside of Memo Blast’s own marketing, the reporting names several supplements with evidence of BBB penetration: alpha‑GPC (a choline donor), huperzine A (an alkaloid), and magnesium L‑threonate (marketed as Magtein) are each discussed as having BBB activity or marketing claims of brain bioavailability [4] [5]. The supplied Memo Blast materials do not, however, confirm inclusion of alpha‑GPC, huperzine A or magnesium L‑threonate in Memo Blast’s formula, so one cannot conclude these BBB‑crossing actives are present in Memo Blast from the current reporting [1] [2].
4. How scientists determine BBB crossing — why marketing language can be misleading
The reporting outlines that BBB permeability is mechanism‑dependent (transmembrane diffusion, transporters, endocytosis), and that predicting which molecules cross in humans relies on complex algorithms, models and human studies — not on marketing claims [7] [8] [9]. Cleveland Clinic coverage cited in the sources stresses that thousands of molecules may cross under varying conditions, and that proving meaningful brain uptake generally requires targeted pharmacokinetic or clinical studies [9]. That gap is where supplement marketing often overstates implication.
5. What can be responsibly concluded from the supplied sources
On the narrow question “Which active ingredients in Memo Blast cross the blood‑brain barrier in humans?” the supplied reporting only establishes that Memo Blast markets Ginkgo biloba as an active [1] [2] and that independently some classes of natural compounds and particular supplements have documented BBB permeability [6] [4] [3] [5]. The supplied material does not include human pharmacokinetic or clinical data proving that Ginkgo‑derived molecules from Memo Blast, or other proprietary actives in Memo Blast, reach the human brain; therefore a firm, source‑backed list of Memo Blast ingredients that definitively cross the human BBB cannot be produced from these sources alone [1] [2] [3].
6. Bottom line and reporting limitations
Manufacturers claim cognitive benefit and cite ingredients linked in other research to BBB crossing, but the documents provided here do not offer the ingredient sheet or human absorption studies necessary to state with evidence which Memo Blast actives cross the human BBB; independent literature suggests candidate compounds that do cross (polyphenols, certain alkaloids, alpha‑GPC, magnesium L‑threonate), yet their inclusion in Memo Blast is not corroborated by the supplied marketing pages [1] [2] [3] [4] [5]. To answer conclusively would require Memo Blast’s full ingredient list and peer‑reviewed human pharmacokinetic or clinical trials showing central uptake.
