The Bioavailability Lesson

This is the part I still think families need to understand, even if they never try anything like what we tried.

Important: This is not a recipe, protocol, or recommendation. I am deliberately not giving exact amounts, temperatures, timing, sourcing, or a step-by-step process.

I do not know whether our attempt helped, did nothing, or harmed. What I can share is the problem we were trying to solve and the lessons I wish I had understood earlier.

The Problem We Were Trying to Solve

After reading about repurposed drugs and compounds like mebendazole, ivermectin, curcumin, and others, one problem kept showing up: absorption. A compound can look powerful in a dish and still barely reach the bloodstream when swallowed as a normal pill or powder.

Mebendazole especially bothered me. It is poorly soluble, and a lot of the discussion around it online treats the dose as if swallowing more automatically means the body is getting more. That is not how pharmacology works. If a compound does not dissolve well, absorption can become wildly inconsistent.

At the same time, my mom was struggling with pill burden, nausea, and a stomach that had been through too much. The practical problem was not just "what agents look interesting?" It was "how could anyone tolerate all of this, and how much is actually getting in?"

Why SEDDS Caught My Attention

In pharmaceutical research, self-emulsifying drug delivery systems (SEDDS) and related lipid formulations are used to improve absorption of poorly soluble compounds. The basic idea is that oils, surfactants, co-solvents, and emulsifiers can sometimes help a stubborn compound disperse into much smaller droplets after it hits the gut.

That matters because smaller droplets can create far more surface area. More surface area can mean better dissolution. Better dissolution can mean better absorption. In controlled research, this can produce big differences in exposure.

The danger is that the same logic cuts both ways. If absorption goes up, toxicity and drug interactions can go up too. "More bioavailable" is not automatically safer. It can be the opposite.

What We Tried, Broadly

We tried to create a crude, home version of a lipid-based approach for a poorly soluble drug. Broadly speaking, the idea involved dissolving or dispersing a finely crushed compound, combining it with a lipid/emulsifier system, and using agitation to try to push it toward a more uniform liquid.

That sounds cleaner than it was. We did not have pharmaceutical equipment. We did not have particle-size testing. We did not have assay testing to prove how much was dissolved versus suspended. We did not have stability data. We did not have therapeutic drug monitoring. We had theory, desperation, and visual guesses.

Visually, the result was not what I wanted. A true nanoemulsion is usually expected to look much more uniform and often more transparent. What we ended up with looked cloudy. My best guess is that it was closer to a microsuspension with undissolved particles than the clean formulation I had hoped for.

Where I Think It Went Wrong

Looking back, I think there were several problems. The compound likely needed a stronger and more appropriate solubilizing system than what we were using. The container setup may have introduced moisture. Moisture can matter because even tiny amounts can change how a poorly soluble drug behaves. We were also trying to solve a pharmaceutical problem without pharmaceutical controls.

The bigger issue was her body. By that point, her stomach was already damaged and reactive. Something that might be tolerated in a healthy gut can become brutal in a fragile one. After more bloating and pain, and after another hospital visit, it became obvious that the gut situation changed the entire risk calculation.

Around that same time, we learned that the tumor on her liver had grown quickly. Her liver enzymes had not warned us in the way I would have expected. That was one of the cruelest lessons: labs can look stable while the disease is still moving.

What I Wish I Had Understood Earlier

  • Poor absorption can make a protocol look weaker than it is, but improving absorption can also make it more dangerous.
  • A cloudy mixture, visible particles, or inconsistent dispersion can mean the formulation is not doing what you think it is doing.
  • Gut damage changes everything. The same substance can behave very differently in a healthy GI tract versus an inflamed or radiation- damaged one.
  • Without testing, you do not know the dose the body is actually seeing. You only know what went into the mixture.
  • Piperine, grapefruit, oils, solvents, emulsifiers, and other "bioavailability boosters" are not harmless tricks. They can change exposure to multiple drugs at once.

The Bottom Line

I still think bioavailability is one of the most under-discussed issues in alternative and repurposed-drug cancer circles. People compare doses as if everyone absorbs the same amount. They do not. Formulation, food, bile, gut health, genetics, drug interactions, inflammation, and liver metabolism can all change exposure.

But I also think this is exactly why people should be careful. Once you start trying to manipulate absorption, you are no longer just "taking a supplement." You are changing pharmacokinetics. That is a serious medical question, not a kitchen experiment.

If this page does anything useful, I hope it makes people ask better questions: How well is this absorbed? What changes its absorption? What else could it raise levels of? What labs should be watched? Is there any human data? And who qualified can help think through it?

Nanosensitizers for sonodynamic therapy for glioblastoma multiforme: current progress and future perspectives

Military Medical Research · Jun 2022 · systematic review

glioblastoma multiformebrain tumors

This review summarizes recent studies of nanosensitizers used in sonodynamic therapy (SDT) for glioblastoma. It explains that SDT combines sonosensitizers with low-intensity ultrasound to kill deep-seated tumors but that conventional sensitizers have limited ability to reach brain tumors across the blood-brain barrier. The authors highlight that multifunctional nanosensitizers and new combination strategies have improved SDT selectivity and tumor-killing ability while reducing side effects, and they outline promising directions for future research.

Studied with: low-intensity ultrasound.

Key findings
  • Glioblastoma multiforme (GBM) is highly invasive, genetically heterogeneous, and protected by the blood-brain barrier, all of which reduce treatment efficacy.
  • Sonodynamic therapy (SDT) uses activated sonosensitizers coupled with low-intensity ultrasound and can provide tumor-killing effects for deep-seated tumors such as brain tumors.
  • Conventional sonosensitizers cannot effectively reach the tumor region in the brain and kill additional tumor cells, indicating a need for delivery strategies across the blood-brain barrier.
  • Development of multifunctional nanosensitizers and emerging combination strategies has improved the killing ability and selectivity of SDT and is associated with fewer side effects.
  • The review systematically summarizes previous studies on SDT for GBM and highlights recent developments and promising future directions.
Limitations: This is a review article and does not present new experimental or clinical trial data.; The abstract implies focus on technological and preclinical advances; clinical evidence for nanosensitizer SDT in GBM is not reported in the abstract.; Because the article summarizes prior studies, conclusions depend on the design and quality of the included studies (which may be preclinical/in vitro or animal models)..

Doxorubicinbreast cancer (4T1 mouse xenograft model)

The authors developed a contractible hydroxypropyl methyl cellulose (HPMC)/Fe3O4 hydrogel designed to release doxorubicin in response to pH and an applied magnetic stimulus. In vitro, the DOX-loaded hydrogel showed notable pH-sensitive drug release. In mice bearing 4T1 breast cancer xenografts, combined chemo-magnetic hyperthermia treatment with the hydrogel led to recovery without recurrence or metastasis and was reported to produce reduced toxicity and superior anticancer effects.

Studied with: doxorubicin, magnetic hyperthermia.

Key findings
  • A contractible HPMC/Fe3O4 hydrogel with dual pH- and magnetic-response properties was developed as a drug delivery system.
  • The HPMC/Fe3O4/DOX hydrogel displayed a remarkable pH-sensitive drug release profile in vitro.
  • After synergistic chemo-magnetic hyperthermia treatment, mice with 4T1 breast cancer xenografts recovered without any recurrence or metastasis.
  • The combined pH- and magnetic-hyperthermia response reportedly produced reduced toxicity and superior anticancer effects.
Limitations: Preclinical study limited to in vitro experiments and a single mouse xenograft model (4T1); results may not translate to humans.; Abstract does not report sample size, dosing details, treatment schedule, control groups, or follow-up duration.; Efficacy and safety assessments appear limited to the animal model; no clinical/human data provided..

Targeted Delivery of Hyaluronan-Immobilized Magnetic Ceramic Nanocrystals

Journal of biomedical nanotechnology · Jan 2016

breast cancer (MDA-MB-231 cell line)

The authors synthesized hyaluronic acid (HA)-modified magnetic hydroxyapatite nanocrystals and characterized their physicochemical properties. They report successful immobilization of HA via a PEG spacer, good biocompatibility, adequate biodegradation, superparamagnetic behavior, and uptake/localization of the particles into HA-receptor–overexpressing cancer cells (e.g., MDA-MB-231), proposing their use as heat mediators for intracellular hyperthermia in cancer therapy.

Key findings
  • HA targeting moiety conjugated by a poly(ethylene glycol) (PEG) spacer arm was successfully immobilized on the surface of mHAP.
  • HA-modified mHAP possesses relatively good biocompatibility, an adequate biodegradation rate and superparamagnetic properties.
  • HA-modified mHAP could be localized and internalized into HA receptor-overexpressed malignant cells (e.g., MDA-MB-231 cell).
  • HA-modified mHAP can be used as the heat generating agent for intracellular hyperthermia, indicating promise as a targeting nanoagent for intracellular hyperthermia cancer therapy.
Limitations: Findings are reported at the in vitro/cell-line level only; no in vivo or clinical data in the abstract.; Abstract does not report quantitative efficacy or safety metrics.; Mechanistic details beyond particle uptake and heat-generation potential are not fully elucidated in the abstract.; No assessment of in vivo biodistribution, toxicity, or therapeutic efficacy is reported..

Magnetic Gel Composites for Hyperthermia Cancer Therapy

Gels (Basel, Switzerland) · Sep 2015 · tutorial review (narrative)

unspecified tumor tissue / cancer (general)

This tutorial review summarizes the properties and formulations of biocompatible thermo-responsive magnetic gel composites proposed for magnetic hyperthermia cancer therapy. It explains that magnetic particles generate heat under an external alternating magnetic field (via hysteresis loss), that heating can raise tissue temperature into the hyperthermia range, and that thermo-responsive gels can undergo volume changes and potentially release previously entrapped anti-cancer drug molecules.

Reported effect: hyperthermia_temperature_range 41

Studied with: radiation, anti-cancer drugs.

Key findings
  • Magnetic hyperthermia involves introducing magnetic micro/nanoparticles into tumor tissue and applying an external magnetic field to heat the area.
  • Heating arises mainly from hysteresis loss in magnetic particles subjected to a magnetic field, raising system temperature.
  • Thermo-responsive gels, once temperature crosses their lower critical solution temperature (LCST), undergo large volume changes and may deliver anti-cancer drug molecules previously entrapped in their networks.
  • The review describes main properties and formulations of magnetic gel composites conceived for magnetic hyperthermia therapy.
Limitations: This is a tutorial/narrative review and does not present original experimental data.; Abstract does not report any in vivo or human clinical data or quantitative efficacy outcomes.; No specific tumor types, sample sizes, or experimental conditions are provided in the abstract.; No information on safety, dosing, or clinical feasibility is provided in the abstract..

Tetraspecific ligand for tumor-targeted delivery of nanomaterials

Biomaterials · Jul 2014

The authors engineered a fusion "tetraspecific" ligand that recognizes four cancer-associated receptors (VEGFR2, αvβ3 integrin, EGFR, HER2) and can be highly expressed and purified from E. coli. In vitro binding studies (SPR, BLI) showed each subunit binds its target similarly to monospecific ligands, and when conjugated to gold nanoparticles the ligand enabled target-dependent hyperthermic killing of cancer cell lines; the ligand can bind more than one receptor on the same cell.

Studied with: gold nanoparticles (AuNPs).

Key findings
  • A tetraspecific fusion protein ligand recognizing VEGFR2, αvβ3 integrin, EGFR, and HER2 was generated by sequentially connecting four targeting subunits via flexible linkers.
  • The fusion protein can be highly expressed in Escherichia coli and purified to near homogeneity.
  • SPR, BLI, and cellular binding analyses indicated each targeting subunit in the tetraspecific fusion protein recognized its receptor proximally to the corresponding monospecific ligands.
  • The tetraspecific ligand was attached to gold nanoparticles (AuNPs) and enabled efficient target-dependent hyperthermic killing of various cancer cell lines; killing was achieved only when AuNPs were conjugated with the tetraspecific ligand.
  • In vitro assays showed the tetraspecific ligand can simultaneously interact with more than one receptor (e.g., EGFR and HER2) on the same cell, consistent with multivalency and synergistic binding.
Limitations: All reported experiments were in vitro (cell lines); no in vivo or clinical data are presented in the abstract.; The abstract does not specify which cancer cell lines or quantitative efficacy measures were used.; Safety, toxicity, pharmacokinetics, and immunogenicity of the ligand-AuNP constructs are not addressed.; No sample sizes, statistical values, or numeric outcome metrics are reported in the abstract..

Magnetic nanoparticles for theragnostics

Advanced drug delivery reviews · Jun 2009 · review

This is a review of engineered magnetic nanoparticles (MNPs), describing their uses in imaging, guided delivery, hyperthermia and other biomedical applications, and discussing emerging theragnostic applications. The authors summarize evidence that certain nanoparticle properties can increase cytotoxic potential via oxidative stress followed by inflammation and DNA damage, and they discuss how size, composition and surface chemistry affect uptake, biodistribution, macrophage recognition and toxicity.

Studied with: drug delivery, gene delivery, magnetic hyperthermia, MRI-guided therapy, cell tracking.

Key findings
  • MNPs have been applied to MRI, guided drug and gene delivery, magnetic hyperthermia cancer therapy, tissue engineering, cell tracking and bioseparation.
  • Theragnostic applications are emerging, e.g., MRI-guided cell replacement therapy and MRI-based imaging of cancer-specific gene delivery.
  • Certain nanoparticle properties (enhanced reactive area, ability to cross barriers, resistance to biodegradation) can amplify cytotoxic potential relative to molecular or bulk counterparts.
  • A 3-tier paradigm of nanotoxicity is described: activation of reactive oxygen species (tier I), a proinflammatory response (tier II), and DNA damage leading to apoptosis and mutagenesis (tier III).
  • In vivo administered MNPs are rapidly challenged by macrophages of the reticuloendothelial system (RES), reducing circulation time and potentially limiting efficacy.
  • Size, composition and surface chemistry influence intracellular uptake, biodistribution, macrophage recognition and cytotoxicity, and engineering strategies are reviewed to optimize MNPs for biomedical use.
Limitations: This article is a review and presents synthesis of existing studies rather than new primary experimental data.; Findings are based on heterogeneous preclinical and translational studies, so generalizability to human clinical outcomes is uncertain.; The abstract notes caveats in nanotoxicity assessments, implying variability and potential limitations in the underlying evidence base..
