Mindsip insights from this episode:
Beware of kratom isolates causing opioid-like respiratory depression
New research shows that commercially sold Kratom isolates, specifically 7-hydroxymitragynine, can cause respiratory depression equivalent to traditional opioids.
Discover Coca-Cola's secret ingredient: de-cocainized coca leaf extract
Coca-Cola is the major importer of coca leaves to the US, using a de-cocainized extract as the secret flavoring ingredient in products like Coke Classic and Coke Zero.
Discover the medicinal origins of soft drinks
Many original soft drinks were developed as pharmacological tools, such as 7Up which contained lithium for mood and Pepsi which contained the digestive peptide pepsinogen.
Understand kratom's antifungal defense mechanism
The Kratom tree produces its complex alkaloids not for human benefit, but as a highly effective chemical defense against fungus in its native hot, humid environment.
Utilize lower doses of kratom for greater benefits
Many regular users of Kratom leaf products report that "less is more," deriving greater benefit from lower amounts rather than developing a tolerance that requires higher doses.
Recognize kratom isolates as pure opioids in commercial market
Unlike the complex leaf, specific Kratom-derived isolates like 7-hydroxymitragynine are pure opioids that are now being sold commercially.
Utilize kratom's diverse alkaloids for multifaceted brain support
The Kratom plant is like a "pharmaceutical shotgun" because its various alkaloids simultaneously target the opioid, serotonin, and adrenergic systems in the brain.
Recognize kratom's widespread daily use among 20 million Americans
While official reports suggest around 2 million users, industry sales data estimates that over 20 million people in the US use Kratom products on a daily basis.
