Vitamin D is a steroid prohormone with a receptor in virtually every tissue — and its deficiency is a global public-health problem that shows up in your practice as low bone density, weak muscle, falls and fractures. Nutrition 227 delivers a rigorous, evidence-based review of vitamin D physiology, the downstream effects of deficiency on bone and skeletal muscle, and actionable clinical guidance on serum 25(OH)D testing, supplementation dosing, cofactors and patient management.
Dr. Howard Benedikt works through cutaneous UVB synthesis, hepatic 25-hydroxylation and renal activation to calcitriol and its genomic signaling through the vitamin D receptor in bone, intestine and muscle; the epidemiology and risk factors of deficiency — limited sun, darker skin pigmentation, obesity, malabsorption, aging; calcitriol’s role in calcium and phosphate absorption, bone mineral density, osteomalacia, osteoporosis and fracture risk; VDR expression in muscle and the type II fiber atrophy that costs grip strength, gait speed and balance; and the clinical program — 25(OH)D as the standard biomarker, deficiency below 20 ng/mL, insufficiency 20–29 and sufficiency at 30 or above, cholecalciferol versus ergocalciferol, loading and maintenance dosing, vitamin K2 and magnesium as cofactors, and monitoring.
Choose Your Nutrition Path — Three Lanes, One Curriculum
The Nutrition library — sixty-eight courses by Howard Benedikt, DC, DCBCN — organizes into three working lanes: the gut, the brain, and the conditions you already treat. Nutrition 201–210 is the foundation block, 211–220 the second, 221–230 the third, 231–240 the fourth, 241–250 the fifth, and 201–224 together form the 48-hour Clinical Nutrition Certification (CNC). Two hours each.

What You’ll Learn in Nutrition 227
Understand how vitamin D is synthesized, metabolized and activated — UVB photosynthesis, hepatic 25-hydroxylation, renal 1-alpha-hydroxylation to calcitriol and signaling through the vitamin D receptor.
Describe the prevalence of deficiency and its risk factors — limited sun exposure, darker skin pigmentation, obesity, malabsorption and aging.
Identify the musculoskeletal consequences of deficiency, including effects on calcium absorption, bone mineral density, osteomalacia, osteoporosis and fracture risk.
Explain vitamin D’s role in skeletal muscle — type II fiber atrophy, grip strength, gait speed and fall risk — and the intervention evidence in older adults.
Evaluate serum 25(OH)D testing and interpret results — deficiency, insufficiency and sufficiency thresholds — to guide patient care.
Apply evidence-based supplementation strategies — D3 versus D2, loading and maintenance dosing, vitamin K2 and magnesium cofactors, and monitoring — in chiropractic practice.

Where Nutrition CE Hours Count — State Rules Worth Knowing
Nutrition coursework is clinical subject matter — assessment, clinical reasoning and nutritional management of patient conditions — which is exactly what several state boards ask for. In Iowa, these hours serve the 36-hour clinical case-management minimum; in Rhode Island, they address the 50-of-60 clinical requirement; and in Vermont — where practice-building coursework earns nothing — patient-care education like this counts fully under the clinical-focus rule.
Online-format allowances still vary by state — some accept every hour online, others cap distance learning or require in-person blocks. Check your state’s guide in the full state directory before building your renewal plan.
Build Your Nutrition Block — or Take the Credential
Every course in the Nutrition series runs 2 hours at $40, so the automatic discounts do the bundling for you: 6–9 hours in one order earns 10% off, and 10 or more earns 20% off — any ten courses from the series is 20 hours, which clears the 20% tier at roughly $320 instead of $400, with no promo codes. Vitamin D & Musculoskeletal Health pairs naturally with Nutrition 226 on menopause and estrogen and Nutrition 229 on sports injuries; the three together reach 6 hours and the 10% tier.

Nutrition 227 — Frequently Asked Questions
What does Nutrition 227 cover?
Nutrition 227 covers vitamin D and musculoskeletal health for chiropractors: how vitamin D is synthesized and activated and signals through the vitamin D receptor, the prevalence and risk factors of deficiency, its consequences for calcium metabolism, bone mineral density, muscle-fiber composition, strength and fall risk, and the clinical program of 25(OH)D testing, dosing, cofactors and monitoring. Also known as vitamin D for chiropractors, vitamin D deficiency and bone health, or the vitamin D testing-and-dosing course.
Which laboratory test should chiropractors order to evaluate vitamin D status?
Serum 25-hydroxyvitamin D — 25(OH)D — the major circulating form and the best index of overall status, reflecting both intake and cutaneous synthesis. The active hormone, 1,25(OH)2D, has a short half-life and is tightly regulated, so it is not a reliable measure of stores. The course gives the interpretation thresholds used in practice: deficiency below 20 ng/mL, insufficiency 20–29 ng/mL and sufficiency at 30 ng/mL or above.
How does vitamin D deficiency contribute to muscle weakness and falls in older adults?
Skeletal muscle expresses the vitamin D receptor, and adequate calcitriol is required for muscle protein synthesis and maintenance of fast-twitch (type II) fiber diameter. Deficiency selectively atrophies those fibers — the ones responsible for rapid, stabilizing contractions — producing impaired balance, slower gait, weaker grip and higher fall risk. Trials in older adults with low vitamin D show measurable improvements in muscle function and fall reduction with supplementation.
Which form and cofactors does the course recommend for supplementation?
Cholecalciferol (D3) is compared with ergocalciferol (D2) for potency and duration, with loading protocols, maintenance dosing and monitoring strategies laid out for clinical use. Vitamin K2 and magnesium are covered as the cofactors that direct calcium to bone and support the enzymes that activate vitamin D in the first place.
How many CE hours is it, and where does it sit in the Nutrition series?
It is 2 PACE-approved CE hours. Nutrition 227 sits in the musculoskeletal, immune, hormonal and clinical-conditions lane of the Nutrition series with Dr. Howard Benedikt, alongside Nutrition 202 (Arthritic Disease), 207 (Microbiota & the Musculoskeletal System), 226 (Menopause and Estrogen) and 229 (Sports Injuries).
State Approval and Licensing Reminder
