When the gut barrier becomes compromised, a flood of invisible toxins — called endotoxins — can leak into the bloodstream, triggering inflammation, fatigue, brain fog, and chronic illness. In this follow-on article to “All Disease Begins in the Gut,” Sebastian Siebert Supplements explores how endotoxins undermine human health, and how restoring microbial balance with FLORISH Spore Probiotic with Fulvic Acid and FULFIXER Fulvic Acid can stop this toxic cycle from within.

Detoxing After COVID: Clearing the Spike Protein Naturally
Emerging research shows that the COVID spike protein may linger in some individuals, driving inflammation and fatigue long after infection or vaccination. In this new post, we explore the latest science behind spike protein persistence — and share a functional medicine protocol using FLORISH Spore Probiotic with Fulvic Acid and FULFIXER Fulvic Acid to help the body recover, detoxify, and restore balance at a cellular level.

Emerging research shows that fragments of the COVID spike protein can linger in the body, driving fatigue and inflammation. FULFIXER Fulvic Acid helps your system restore balance by binding toxins, reducing oxidative stress, and supporting natural detox pathways.
Formulated for purity and performance, FULFIXER is your ally in post-viral recovery — helping you rebuild energy, clarity, and resilience from the inside out.

We’ve long believed that killing all bacteria in the mouth equals good hygiene — but modern research says otherwise. The oral microbiome is a living ecosystem vital for digestion, nitric oxide production, and immune balance. Overusing antiseptic mouthwash can disrupt this delicate balance, leading to inflammation, poor nitric oxide conversion, and even systemic health issues. In functional medicine, we now see oral health as part of whole-body wellness. Support your mouth’s microbiome naturally with gentle oral care and microbiome-supportive supplements like FLORISH Spore Probiotic and FULFIXER Fulvic Acid from Sebastian Siebert Supplements.

Optimal hydration goes beyond drinking water — it’s about the balance of salts and minerals that keep every cell in your gut functioning. Sodium, potassium, magnesium and trace minerals regulate digestion, motility, and the mucus barrier that protects your intestinal wall. Natural mineral waters or unrefined salts support this balance, while over-refined or excessive salt can disrupt gut microbes. When hydration is paired with mineral diversity and probiotic support from supplements like FLORISH Spore Probiotic with Fulvic Acid, your gut environment thrives — promoting better absorption, reduced inflammation and overall vitality.
