ViTAL-SCAN is a specially designed nutraceutical supplement created for this clinical trial. It combines several natural compounds that may help restore energy metabolism, reduce inflammation, and improve quality of life in people with Post-Acute COVID-19 Vaccination Syndrome (PACVS).

The formulation includes:

• Vitamin C – supports immune and antioxidant function.
• Taurine – important for energy metabolism and muscle function.
• Acetyl L-Carnitine (ALCAR) – helps cells produce energy from fatty acids.
• L-Serine / Sarcosine – amino acids that support brain and nervous system health.
• Creatine & L-Citrulline – improve energy reserves, blood flow, and exercise capacity.
• N-Acetylcysteine (NAC) & L-Arginine – support detoxification, nitric oxide production, and circulation.
• Nicotinamide Mononucleotide (NMN) – a precursor to NAD+, which fuels cellular energy and repair processes.

These ingredients were chosen because they target mitochondrial function, metabolism, and inflammation, areas believed to play a major role in PACVS symptom
