Vitamin D Supplementation for Extraskeletal Indications in Older Persons

Area of Science:

• Geriatric Medicine
• Endocrinology
• Nutritional Science

Background:

• Low vitamin D levels are linked to prevalent geriatric conditions like fractures, functional decline, cancer, cardiovascular disease, and depression.
• Vitamin D supplementation is standard for osteoporosis but its role in other geriatric conditions is debated.
• Clinicians face challenges balancing recommendations for screening, supplementation, and monitoring vitamin D.

Purpose of the Study:

• To review evidence on vitamin D supplementation for sarcopenia, cognition, depression, cancer prevention, and mortality in the elderly.
• To provide guidance on vitamin D screening, supplementation, and monitoring for geriatric patients.
• To evaluate the benefits versus risks of vitamin D supplementation in the geriatric population.

Main Methods:

• Systematic review of existing literature on vitamin D supplementation and geriatric health outcomes.
• Analysis of evidence for specific conditions including sarcopenia, cognitive function, depression, cancer, and mortality.
• Formulation of recommendations based on the strength of evidence and clinical relevance.

Main Results:

• Evidence suggests vitamin D supplementation may decrease mortality in older adults.
• Routine oral cholecalciferol (800-1000 IU daily) is suggested for all adults aged 65+ without contraindications, without routine screening or monitoring.
• For depression or cognitive disorders, screening, treatment with cholecalciferol, and monitoring to >30 ng/mL are recommended as adjuncts to standard care.

Conclusions:

• Routine vitamin D supplementation with cholecalciferol may be reasonable for all individuals aged 65 and older.
• Vitamin D treatment for depression and cognitive disorders should be considered as an adjunct therapy.
• The potential benefits of vitamin D supplementation in the geriatric population outweigh the minimal risks.
