Vitamin Considerations in CKD and ESRD (2026)
An all-in-one, renal-specific vitamin toolkit built for quick reference before visits, lab reviews, and supplement conversations.
Cost: $95

Why this course
Vitamin questions in CKD and ESRD are rarely as simple as “low intake = supplement.” Absorption, dialysis losses, medications, inflammation, lab interpretation, toxicity risk, and patient history can all change how we think about vitamin therapy in renal care.
This course gives renal dietitians an organized, vitamin-by-vitamin reference to revisit when those questions come up in practice, including:
- Biochemistry and clinical function
- DRI/RDA context and where those values come from
- CKD and ESRD-specific considerations
- Deficiency and toxicity concerns
- Supplementation approaches, forms, and precautions
- Vitamin interactions and patient-history considerations
- Renal vitamin formulations and their role in practice
Topics covered include B vitamins, the methylation pathway, vitamins C, E, D, K, and A, plus a 2026 update on vitamins, supplementation, the gut microbiome, and what it may mean for CKD care.
Important Details
- 3.5 CPE*
- Organized by individual vitamin lessons for easier reference
- 13 vitamins covered with renal implications
- Lifetime access to recordings, slides & clinical tools
- Vitamin clinical guide with testing, intake, deficiency/toxicity signs, and interventions
- 2026 update on vitamins, supplementation, the gut microbiome, and implications for CKD care
