Sea Moss for IgA Nephropathy: Anti-Inflammatory, Galactose-Deficient IgA1 & Renal Support

IgA nephropathy (Berger's disease) is the most common primary glomerulonephritis worldwide, affecting ~2-3 per million annually, caused by galactose-deficient IgA1 (Gd-IgA1) immune complex deposition in the glomerular mesangium, triggering complement C3/C4b-mediated mesangial proliferation, NF-kB amplification, TGF-beta fibrosis, and progressive CKD. IgAN involves APRIL/BAFF-driven IgA1 O-glycosylation defects, Th2 IL-4/IL-5/IL-13 mucosal dysregulation, and ALT/ACE2 crosstalk. Sea moss fucoidan modulates complement mesangial C3/C4b and NF-kB; selenium supports renal tubular GPx and podocyte GPx4 protection; zinc supports mesangial metallothionein and FOXP3+ Treg; omega-3 EPA/DHA modulates mesangial eicosanoid LTB4/TXA2 and has direct evidence in IgAN trials. ACE inhibitors/ARBs, sparsentan, budesonide (targeted release), and omega-3 supplementation are standard; sea moss provides anti-inflammatory nutritional support.
