Long COVID in Belgium: post-COVID fatigue, sugar and ginger INTI (NLRP3, mitochondria, microbiome) 2025

Long COVID in Belgium: 200,000 people affected

In Belgium, it is estimated that 10 to 15% of people who have had COVID-19 develop long COVID — symptoms persisting for more than 12 weeks after acute infection. This represents approximately 200,000 Belgians, many of whom suffer from severe fatigue, cognitive fog, muscle pain, dyspnea, and ginger for tinnitus.

The three biological mechanisms of long COVID

1. Persistent NLRP3 inflammasome

SARS-CoV-2 activates the NLRP3 inflammasome in macrophages, microglial cells, and endothelial cells. Normally transient, this activation becomes persistent in long COVID patients:

• NLRP3 → caspase-1 → IL-1β and IL-18 → cell pyroptosis → chronic systemic inflammation
• IL-1β → neuroinflammation → cognitive fog (brain fog)
• NLRP3 in platelets → hypercoagulability → microclots → tissue fatigue

Sugar aggravates: glucose → AGE → RAGE → NLRP3 ↑. Each sugary drink therefore amplifies the persistent inflammasome of long COVID.

2. Mitochondrial dysfunction and unexplained fatigue

SARS-CoV-2 directly damages mitochondria in muscle and nerve cells via:

• ORF9b → targeting of TOM70 complex → disturbed mitochondrial import
• Persistent oxidative stress → mitochondrial DNA (mtDNA) damage
• Inhibited AMPK (by chronic inflammation) → mitochondrial biogenesis ↓

Result: insufficient ATP for muscle and brain needs → characteristic post-COVID fatigue (PEM — Post-Exertional Malaise).

6-gingerol activates AMPK → PGC-1α → mitochondrial biogenesis → ATP ↑ → improved exercise tolerance.

3. Post-COVID gut dysbiosis and systemic inflammation

COVID-19 infection permanently disrupts the gut microbiome: reduction of Faecalibacterium prausnitzii and Bifidobacterium (anti-inflammatory), increase of Ruminococcus gnavus and Clostridium (pro-inflammatory). This dysbiosis generates an excess of LPS (bacterial endotoxin) → intestinal translocation → systemic NF-κB → persistent inflammation.

Dietary sugar aggravates this dysbiosis by promoting the growth of pro-inflammatory bacteria. Ginger (6-gingerol + 6-shogaol) has partial antimicrobial and prokinetic properties promoting microbiome normalization.

Comparison of drinks for long COVID patients

Long COVID protocol with INTI

Long COVID requires a holistic approach (medical, nutritional, pacing). INTI can be integrated as daily support:

• Morning: 1 INTI shot on an empty stomach or with breakfast — AMPK ↑ for the day
• After exertion (pacing): INTI diluted in water — NLRP3 ↓ post-exertion
• Avoid: sugary drinks, energy drinks, GIMBER (sugar amplifies NLRP3 and dysbiosis)
• Combine: Omega-3 (EPA/DHA), magnesium, vitamin D — synergistic with 6-gingerol on NLRP3
