In this YouTube short, Dr. Tabatha Barber shares a personal account of a period when her Hashimoto's disease was at its most severe. She reports thyroid antibody levels exceeding 1,000, indicating extreme autoimmune activity. She also reveals that her vitamin D level was extremely low—around 11 to 15 ng/mL—well below the 30 ng/mL threshold she notes as critical for immune competence. Barber emphasizes that vitamin D levels under 30 make a person highly susceptible to illness and impair the body’s ability to fight infections.

That was when my Hashimoto's was the worst. It was so out of control. My antibodies were over 1,000. Like, they just didn't register. They were over 1,000. And I'm guessing you weren't taking a vitamin D supplement. No, my vitamin D was like, I don't know, 11 or 15. It was something ridiculous in the teens. And like, under 30, you are so susceptible to disease and getting sick and not being able to fight that off.
