Fibrosis
Abnormal fibrosis can be the result of vitamin K2 deficiency, or magnesium deficiency. Vitamin D deficiency should be ruled out.
Toxic levels of lead and cadmium are highly associated with lung fibrosis. Other toxin exposures are most likely a contributing factor. Paraquat, for example, is a broad spectrum herbicide that works by producing oxidative stress and ferroptosis in cell membranes of plants, degrading NRF2 (an antioxidant signaling pathway). Paraquat accumulates in lungs, and results in fibrosis. Paraquat has been banned in much of the world, but unfortunately is still widely used here in the USA.
Treatment should address the root cause of the pathology. Additionally, I would recommend moderate amounts of vitamin C, glutathione, NRF2 agonists, the peptides GHK-CU (which supports healthy collagen formation) and E4, ICAA. I also recommend sauna therapy, and other forms of detoxication.
If you’ve ever had Covid-19, or an mRNA vaccine, you should check blood levels of spike protein, and use binders to mitigate pathology.
