FoodAug 7, 2026 Magnesium, HRV and POTS: Does It Actually Help, and How to Tell Magnesium is one of the most recommended supplements in POTS and long COVID circles, usually for sleep, palpitations and calmer nerves.

FoodJul 30, 2026 Quercetin and Mast Cells: What the Evidence Actually Shows Quercetin is the most recommended supplement in MCAS and long COVID circles, and the laboratory data on mast cells is genuinely impressive. The human data is much thinner, and there is a large gap between the concentrations that work in a dish and the ones your blood can reach. Here is the honest picture, the safety and interaction issues worth knowing, and how to run a careful trial with your clinician. FoodJul 25, 2026 Why POTS Feels Worse After Eating: Postprandial Hypotension, Explained If your heart races, your head swims, or you crash for an hour after a meal, that is not in your head.

FoodJun 23, 2026 SIBO, Histamine & Why Dysautonomia Wrecks Digestion Dysautonomia doesn't stop at your heart rate, it slows your gut, invites bacterial overgrowth, and can stir up histamine problems.
