Supporting the immune system and managing Mast Cell Activation Syndrome (MCAS) associated with long COVID and vaccine injury can be achieved through a well-rounded combination of supplements and medications. An activated B complex enhances energy production and supports overall immune function, while zinc is crucial for immune response and helps stabilize mast cells, reducing histamine release. Magnesium, essential for hundreds of biochemical reactions, also modulates immune response and stabilizes mast cells.

Vitamin D3, paired with K2 for optimal absorption, plays a vital role in immune regulation and reducing inflammation. Omega 3/6 from cod liver oil provides essential fatty acids that reduce inflammation and support immune health. Low dose naltrexone helps modulate the immune system, reducing chronic inflammation and alleviating MCAS symptoms. Liposomal glutathione, a powerful antioxidant, aids in detoxifying the body and bolstering immune function.

Ketotifen is effective in stabilizing mast cells, preventing the release of histamine and other inflammatory mediators. Antihistamines, including H1 blockers and famotidine (an H2 blocker), help reduce histamine levels, providing relief from MCAS symptoms. Quercetin, a natural flavonoid, offers additional antihistamine and anti-inflammatory benefits, further stabilizing mast cells. Lastly, a low histamine diet minimizes dietary triggers that can exacerbate MCAS, offering further relief and support for the immune system.
