Nutrient Deficiencies in POTS with Nutritionist Jill Brook

In this podcast episode, nutritionist Jill Brook discusses nutrient deficiencies in POTS patients, focusing on four studies addressing Thiamine (B1), Iron, Vitamin B12, and Vitamin D deficiencies. Although POTS patients often face digestive challenges that could affect nutrient absorption, research on this topic is limited. One study found Thiamine deficiency in a small number of POTS patients, with some experiencing symptom improvement upon supplementation. Another study highlighted a higher prevalence of iron deficiency in POTS adolescents. A dubious study on Vitamin B12 associated it with fainting rather than true POTS, while Vitamin D was found to be low in over 50% of POTS patients. Jill shares her personal experiences with supplementation, noting the importance of testing and working with healthcare providers to address deficiencies. She directs listeners to a resource for recommended lab tests to identify nutrient imbalances.
