Many patients with POTS (Postural Orthostatic Tachycardia Syndrome) are told it’s “just bad luck,” but often it’s linked to key nutrient deficiencies. Low levels of B12, folate, copper, and glutathione can impair blood vessel and nervous system function, worsening dizziness, fatigue, and rapid heartbeat. With proper intracellular testing and targeted supplementation, patients can often see major improvements in symptoms and quality of life.
