What if chronic inflammation is the common thread behind many of today’s most serious diseases—and what if reducing it at the cellular level could change how we think about prevention and treatment?
In this episode, Dr. Barrett continues his conversation with biochemical engineer Samuel Shepherd, who began studying oxidative stress and inflammation after facing a serious health diagnosis of his own. What followed was years of research into reactive oxygen species, protein damage, and mitochondrial stress—and how compounds like astaxanthin may influence these processes.
This is a deep, science-focused discussion on how inflammation develops, how cells get damaged, and why aging increases disease risk—not a typical supplement talk. (Astaxanthin and Cancer Recovery)
In This Episode, We Discuss:
- How oxidative stress and free radicals damage proteins, DNA, and mitochondria
- Why antioxidant defenses decline with age
- The role of protein folding in insulin function and metabolic health
- New ways researchers are thinking about neurodegenerative disease mechanisms
- How inflammation and cellular stress may contribute to heart and brain disorders

Show Notes from this episode
00:00 – Introduction
Dr. Barrett welcomes listeners and introduces this as a continuation of last week’s conversation with Samuel Shepherd about astaxanthin’s antioxidant properties and ability to reduce high-sensitivity CRP (hsCRP) values.
- Discussion of his unique “n of one” experiment developing astaxanthin therapy
- Announcement of sponsor code: valasta.net with code POI5 for 5% discount
- Episode topics preview: reactive oxygen species (ROS), inflammation, disease processes
01:21 – Astaxanthin’s Unique Glucose Attachment (The “Trojan Horse” Mechanism)
Samuel explains how ValAsta differs from other astaxanthin supplements:
- Natural form: In algae, astaxanthin exists with glucose chemically attached (glucosidic/liposomal form)
- Standard extraction problem: Supercritical CO2 extraction removes glucose, reducing absorption to 1/8 of the natural form
- ValAsta’s solution: Patented process to reattach glucose to astaxanthin for superior absorption
02:19 – How the Glucose Attachment Works
- Glucose attachment allows astaxanthin to pass through the gut barrier
- Pharmaceutical industry commonly uses glycosides/glucosides for improved drug absorption
- Samuel references his background in chemical weapons development where “Trojan horse” delivery systems were used
02:24 – Cancer Cell Targeting Mechanism
The Trojan Horse Effect:
- Cancer cells have massive metabolic consumption (16x more sugar than normal cells)
- Hydroxyl free radicals generated by cancer metabolism create acidic environment (pH 5.2)
- Cancer cells aggressively pull in glucose-attached astaxanthin
- Once inside, enzymes break off glucose
- Free astaxanthin neutralizes hydroxyl free radicals (OH⁰ → OH⁻¹)
- OH⁻¹ has pH of 11, which kills cancer cells in 4 seconds through saponification of cell membrane
07:05 – Cancer Marker Spike Phenomenon
- CA-125, CA 19-9 markers initially spike dramatically when cancer cells die
- This alarmed oncologists who thought cancer was becoming more aggressive
- Markers drop back to normal within 4 days as cell debris clears
- The spike represents dead cancer cell antigens flooding bloodstream, not cancer growth
07:46 – Dosing Protocol & hsCRP Testing
Step 1: Get baseline hsCRP tested
Dosing guidelines:
- hsCRP 2.5-3.0 mg/L: 0.1 mg per kg body weight (e.g., 70 kg person = 7-10 mg/day)
- hsCRP under 2.0 mg/L: May not need astaxanthin supplementation
- hsCRP over 3.0 mg/L: Higher therapeutic doses needed
- Severe cases: Working with patients with hsCRP of 80+ (typically cancer, heart disease)
08:01 – Additional Inflammatory Markers
Beyond hsCRP, sed rate (ESR) is monitored as secondary marker for inflammation tracking.
08:16 – The “Tree” Model of Disease
Samuel explains his conceptual framework:
- Roots: Causes of ROS (diet, stress, sugar, fructose, smoking, heavy metals, pollution)
- Trunk: Reactive oxygen species (ROS) – the common pathway
- Branches: Different disease manifestations (arthritis, cancer, diabetes, Alzheimer’s, Parkinson’s, heart disease)
- Treatment philosophy: Cut the tree at the trunk (eliminate ROS) rather than treating individual branches (symptoms)
10:57 – Comparative Antioxidant Power
Astaxanthin has significantly more antioxidant capacity than glutathione (considered the “mother of all antioxidants”) and vitamin C.
13:09 – The Importance of Baseline Testing
Before purchasing astaxanthin, get hsCRP tested to establish baseline and determine if supplementation is needed.
13:26 – Cholesterol Myth & Heart Disease
- Misconception: Cholesterol causes heart disease
- Reality: Arterial inflammation causes heart disease
- Cholesterol attempts to heal arterial lesions but forms problematic scabs (plaques)
- hsCRP over 3 mg/L is strong predictor of cardiovascular disease
16:44 – Samuel’s Personal Cardiac Story
Dr. Radislav Stephan Kais (inventor of coronary stent) performed catheterization on Samuel at age 70:
- Finding: Severe systolic kink in LAD (left anterior descending artery) – congenital defect
- Every heartbeat caused mini heart attack due to artery kinking
- Dr. Kais’s prognosis: 30-35 more years of life expectancy despite defect
- Key finding: Zero inflammatory disease anywhere in vascular system at age 70
21:11 – Samuel’s Wife’s Cardiac Results
- Lifetime cholesterol levels of 260-280 (unmedicated)
- Dr. Kais’s finding: “Coronary health of a 20-year-old”
- Zero arterial inflammation despite elevated cholesterol
- This challenged conventional cardiology wisdom about cholesterol
21:22 – West Virginia/Arkansas Genetics Joke
Dr. Kais ruled out genetics as explanation unless there was inbreeding (humorous moment).
21:46 – Dr. Kais’s Response
After seeing Samuel and wife’s results:
- Immediately put all staff on ValAsta
- Now prescribes ValAsta to all coronary patients
- This represents validation from leading interventional cardiologist
22:24 – Brain Cholesterol vs. Heart Cholesterol Paradox
- Brain is 70% cholesterol and needs it for function
- Cardiology pushes to lower cholesterol to 150 for heart health
- Neurology warns this will damage brain function
- The disconnect: Cholesterol isn’t the problem – inflammation is
23:35 – 92% of Disease Deaths Are Inflammatory
Samuel emphasizes that 92% of all disease-related deaths (excluding accidents) are inflammatory in origin.
23:59 – Legal Challenges
Samuel faced two complaints for “practicing medicine without a license”:
- Oregon and Texas medical boards filed complaints
- Both withdrawn when boards understood the biochemistry and patent
- Patent title: “Method for the process of using astaxanthin to treat inflammatory disease, particularly for the treatment of cancer”
- FDA dislikes words: treat, cure, diagnose
24:08 – The Oncologist’s Call
Female oncologist contacted Samuel about 8 stage IV cancer patients:
- All in hospice (2-4 weeks to live)
- All started taking ValAsta independently
- Cancer disappeared in all 8 patients
- Common denominator: All were taking ValAsta
- Her real reason for calling: Her husband diagnosed with stage IV prostate cancer
26:28 – Oncologist’s Shocking Statement
“Nobody in my family is doing chemo or radiation.”
This statement from a practicing oncologist reveals the treatment crisis in conventional oncology.
26:34 – Her Husband’s Results
- PSA dropped from 20s to under 3
- Age 68, now in remission
- Note: Prostatitis can also elevate PSA, not just cancer
26:28 – Limitations of Medical Imaging
PET scans, CAT scans, and MRIs with contrast cannot differentiate between inflammatory lesions and cancer because both light up the same way.
27:17 – Biopsy Risks
Needle biopsies risk breaking open tumors and allowing cancer cells to spread throughout the body.
29:20 – Upstream Intervention Philosophy
IL-1, IL-6, NF-kappa-beta are all results of free radical attack. Astaxanthin works one step earlier by eliminating the hydroxyl and superoxide radicals that trigger these cytokines.
29:20 – The Parkinson’s Disease Case
82-year-old woman in Hershey, Pennsylvania:
- Initial reason for taking astaxanthin: Arthritis treatment
- Unexpected result: Severe Parkinson’s tremors completely stopped
- Could not hold food on fork; daughter had to feed her
- After astaxanthin: All tremors ceased
31:29 – Parkinson’s Disease Mechanism Revelation
Medical dogma: Parkinson’s is caused by lack of dopamine production in substantia nigra
Reality Samuel discovered:
- Substantia nigra produces huge amounts of dopamine
- Dopamine reacts with hydroxyl free radicals → forms hydroxydopamine
- Hydroxydopamine is the actual toxin that causes Parkinson’s symptoms
- Ironically, hydroxydopamine is what researchers give to animals to induce Parkinson’s for drug testing
32:03 – The Dopamine/Hydroxyl Reaction
Chemical equation: Dopamine + Hydroxyl free radical → Hydroxydopamine
Parkinson’s patients have low dopamine-to-hydroxydopamine ratio because all dopamine is being converted.
34:53 – Standard Parkinson’s Treatment Failure
- Medical system gives levodopa or carbidopa to increase dopamine
- This temporarily improves symptoms
- But doesn’t address hydroxyl radicals
- Eventually hydroxyl concentration neutralizes the extra dopamine
- Patients become resistant and die from Parkinson’s
- Astaxanthin approach: Eliminate hydroxyl radicals, stopping the conversion reaction
34:53 – Estrogen and Breast Cancer Truth
Medical dogma: Estrogen causes breast cancer; use estrogen-blocking drugs
Reality:
- If estrogen caused cancer, 16-30 year old women (peak estrogen) would all have cancer
- Actual mechanism: Estrogen + Hydroxyl free radical → Dihydroxyestradiol
- Dihydroxyestradiol is the known carcinogen, not estrogen
- Standard treatment reduces estrogen (wrong target)
- Astaxanthin approach: Remove hydroxyl radical, preventing carcinogen formation
34:53 – Testosterone and Prostate Cancer Parallel
Same mechanism as estrogen:
- Testosterone + Hydroxyl free radical → Hydroxytestosterone
- Hydroxytestosterone causes cancer, not testosterone itself
- Medical system chemically castrates men by reducing testosterone (wrong target)
- Should eliminate hydroxyl radicals instead
35:16 – Why Young People Don’t Get These Diseases
Young people have sufficient glutathione, catalase, and superoxide dismutase to neutralize free radicals, preventing these hydroxylated compounds from forming.
36:20 – The Infertility Crisis Discussion
Dr. Barrett raises concern about current testosterone levels in young men:
- Normal testosterone in young men now averages 200-300 (dramatically low)
- Fertility rates dropping
- Question: Could mRNA technology be causing hydroxylation of testosterone and estrogen?
37:42 – COVID-19 Bioweapon Evidence
Samuel wrote paper to President Trump in March 2021 detailing 8 protocols proving COVID-19 was man-made:
The Genetic Proof:
- Natural RNA has “start codon” (AUU – Adenosine, Uracil, Uracil)
- Ribosome searches along RNA until finding AUU sequence to begin protein synthesis
- Ends at “stop codon” (AUG – Adenosine, Uracil, Guanine)
- In natural RNA, start codon appears randomly, often midway through sequence
- COVID-19 RNA: Start codon was first three nucleotides
- Statistically impossible in nature
- Scientists wanted maximum efficiency with minimal wasted genetic material
- This proves intentional, synthetic construction
42:58 – Craig Venter’s Synthetic Organism
Dr. Craig Venter created synthetic DNA organism in San Diego laboratory that has been living since 2008 – proof that synthetic life can be created.
42:58 – The mRNA Vaccine Problem
- Human body lacks enzymes to break down synthetic RNA from vaccines
- RNA persists in body, constantly producing antigens and proteins
- Accumulates in capillary-rich areas: kidneys (glomerulus), testicles, heart
- Causes myocarditis by inflaming small cardiac capillaries
- Creates “yellow gooky material” extractable from arteries (genetic material from RNA)
- Triggers hyperactive inflammatory response (IL-6, IL-1)
- Cannot be degraded or eliminated by body
43:41 – Molten Aluminum Accident (Samuel’s Personal Story)
September 19, 2024:
- Watching aluminum being poured into mold
- Mold contained residual water drop
- Explosion wrapped molten aluminum around Samuel’s arm
- Third-degree burns
- No hospital visit – treated exclusively with topical astaxanthin
Treatment protocol:
- Applied astaxanthin oil directly to burns
- Applied Neosporin (topical antibiotic)
- Wrapped in white cloth
- Covered with Saran wrap
- Left for 2 days without changing
Results:
- Melted polyester shirt off body
- Burned all hair from under arm
- Skin blown out from pressure
- Complete healing in 6 weeks with no scarring
- No infection
- Would have required burn unit and skin grafts with conventional treatment
46:17 – Pain Management & Healing Mechanism
- Second night had most severe pain (nerve endings burned)
- Astaxanthin didn’t eliminate inflammation (needed for healing)
- Instead, modulated inflammation to physiologic, manageable levels
- This prevented excessive tissue damage while allowing proper healing
47:21 – Engineering Equation for Free Radical Balance
Rate In – Rate Out = Accumulation
- Rate of free radical introduction (diet, stress, environment)
- Minus rate of free radical neutralization (antioxidants)
- Equals accumulation (inflammation level in body)
Astaxanthin increases the “Rate Out” term, allowing accumulation to drop even while still introducing some free radicals.
48:19 – The Serendipity of Samuel’s Journey
Dr. Barrett reflects on how Samuel’s personal diagnosis led him to investigate:
- Which animals don’t get cancer?
- Why don’t they get cancer?
- How can this be applied to humans?
Most patients don’t have the biochemical engineering background to pursue this investigation.
49:05 – Global Impact
- ValAsta now in 26 countries
- International offices established
- No traditional sales or marketing – spread entirely through social media and word-of-mouth
- Cancer patients tell everyone when their cancer disappears
- “This all happened in our lifetime” (regarding social media)
