Nutrition 222 — Hormones and Thyroid Function is a two-hour PACE nutrition CE webinar examining the clinical relationship between hormonal balance, thyroid physiology, and patient fatigue and wellness. The course covers the hypothalamic-pituitary-thyroid axis, how chronic stress and cortisol dysregulation impair thyroid hormone conversion, the immune-modulating role of Vitamin D in thyroid autoimmunity, and how salivary hormone testing and comprehensive lab work enable more accurate clinical assessment.
Instructor Howard Benedikt, DC, DCBCN — President of the Chiropractic Board of Clinical Nutrition — draws on 46+ years of clinical nutrition practice to equip chiropractors with evidence-based protocols for identifying and addressing overlooked hormonal drivers of fatigue and chronic dysfunction. Practitioners earn 2 CE hours toward license renewal.

Human Nutrition CW Post/LIU, and Lead Clinical Nutrition Faculty at CCEDseminars. He delivers PACE- and board-approved curricula via Texas Chiropractic College, holds adjunct positions at New York Chiropractic College and Berkeley College NY, and practices in midtown Manhattan.
How does chronic stress impair thyroid function?
Elevated cortisol from chronic stress inhibits the hypothalamic-pituitary-thyroid (HPT) axis by suppressing TRH and TSH production, reducing thyroid hormone output. Cortisol also inhibits 5-deiodinase, the enzyme responsible for converting inactive T4 into biologically active T3 in peripheral tissues. The result is functional hypothyroidism — symptoms including fatigue, weight gain, and brain fog — even when standard TSH tests appear normal. Nutrition 222 covers how to identify and address this clinically overlooked pattern.
What is the role of Vitamin D in thyroid autoimmunity?
Vitamin D functions as an immune modulator that reduces the Th17/Treg imbalance driving autoimmune thyroid conditions like Hashimoto's thyroiditis. Research shows that Vitamin D deficiency is associated with elevated anti-TPO and anti-TG autoantibody titers. Supplementation — particularly with D3 for more than three months — has demonstrated significant reductions in thyroid autoantibody levels, improved TSH, and slowed disease progression. Nutrition 222 covers clinical protocols for Vitamin D assessment and therapeutic dosing in thyroid patients.
Why is salivary hormone testing useful for thyroid and adrenal assessment?
Salivary testing measures free (unbound) hormone levels rather than total serum levels, making it more accurate in patients with cortisol-binding globulin variations — including those on oral contraceptives or with chronic stress. Salivary cortisol collected across multiple time points maps the diurnal cortisol curve, revealing HPA axis dysregulation patterns that a single serum draw cannot capture. This functional assessment is a cornerstone of the overlooked fatigue protocols covered in Nutrition 222.
Is Nutrition 222 PACE-approved for chiropractic license renewal?
Yes. Nutrition 222 is PACE-approved for chiropractic license renewal in most U.S. states. Visit the CCEDseminars State CE Guidelines page to confirm your state or region's requirements before enrolling.
