Postural Tachycardia and Dizziness (POTS): By supporting the COMT enzyme's ability to clear excess adrenaline and supporting the autonomic nerves responsible for baroreceptor function, B12 may help stabilize heart rate upon standing and reduces the severity of hyperadrenergic adrenaline surges
The study compared three administration routes intraperitoneal, oral (in drinking water), and topical (thin cream layer) all delivered without a carrier
