Episode notes
From Diagnosis To Self-Experimentation
- Samuel Shepherd discovered astaxanthin across cancer-resistant species and grew Hematococcus pluvialis himself to test doses.
- Daily dried-algae astaxanthin reduced his phlebotomy frequency and eventually led him to declare himself cancer-free in 2013.
Hydroxyl Radical As The Disease Trunk
- Four reactive oxygen/nitrogen species drive most inflammatory diseases, with the hydroxyl radical being central.
- Targeting those radicals addresses the root cause rather than treating downstream symptoms.
Glucosidic Form Drives Absorption
- The natural astaxanthin in algae is glucosidic, which increases intestinal uptake compared with the aglycone form.
- Removing that glucose during extraction dramatically reduced bioavailability and efficacy.
