Can I get Enough Vitamin D from Diet Alone?
Can I Get Enough Vitamin D from Diet Alone? is a Continuing Professional Development (CPD) course designed for healthcare professionals working in nutrition, dietetics, primary care, pharmacy, endocrinology, paediatrics, aged care, women’s health, and community healthcare settings. The course provides an evidence-based overview of vitamin D physiology, dietary sources, supplementation, sunlight exposure, deficiency risk, and practical nutritional strategies for achieving adequate vitamin D intake. Vitamin D plays a critical role in bone health, calcium absorption, immune regulation, muscle function, and overall wellbeing. Despite its importance, vitamin D deficiency remains common worldwide across multiple age groups and populations. Factors such as limited sunlight exposure, skin pigmentation, ageing, chronic illness, dietary patterns, and lifestyle behaviours may contribute to inadequate vitamin D status.

Oily fish, egg yolks, liver, and UV-exposed mushrooms are natural sources of vitamin D.
Older adults, people with limited sun exposure, darker skin pigmentation, and certain medical conditions may have increased risk.
