Sea Moss for POTS: Anti-Inflammatory, Autoimmune Adrenergic/ACh Receptor & Autonomic Support

Postural orthostatic tachycardia syndrome (POTS) affects ~1-3 million Americans, predominantly young women, characterized by heart rate increase ≥30 bpm on standing (≥40 bpm in adolescents) without orthostatic hypotension; an autoimmune subset (~50%) has IgG autoantibodies against alpha1-adrenergic receptors (anti-ADRA1), beta2-adrenergic receptors (anti-ADRB2), and muscarinic acetylcholine receptors (anti-M3R/M4R), impaired norepinephrine transporter NET function, small fiber neuropathy from complement C4d/TGF-beta1 ganglion neurite loss, mast cell activation (MCAS overlap), and post-infectious/post-COVID autoimmune dysautonomia trigger. Sea moss fucoidan modulates NF-kB and complement C4d/C3a inflammatory cascades; selenium supports autonomic ganglion neuron GPx1/4 antioxidant defense; omega-3 modulates mast cell PGD2/LTC4 eicosanoids and resolvin E1 neuroinflammation; zinc supports FOXP3+ Treg and skin/nerve TJ barrier integrity. Beta blockers, ivabradine, fludrocortisone, and SSRI/SNRI are standard; IVIG for autoimmune subset.
