Dietary intake: List foods rich in vitamin d, such as fatty fish, fortified dairy, eggs, mushrooms and fortified milk products.

Monitoring and Testing Vitamin D Levels

Vitamin D Test: Advise individuals who are at risk for deficiency, or have symptoms of vitamin D deficiency to consider blood testing to determine their levels.

Monitoring Adjusting: Discussing regular monitoring of supplementation and lifestyle habits and making adjustments based on the test results.

Sun Safety Vitamin D Balance

Balance Sun Exposure: Stressing the importance of sun safety while ensuring adequate exposure for vitamin D syntheses, such as using sunscreen and limiting exposure at peak hours.

Alternative sources: Discussing alternatives strategies to obtain vitamin D through fortified food or supplements, particularly for those with limited sun exposure.

Vitamin D and Mental Health

Mood Regulation Examining research that links vitamin D levels to mood regulation, mental health and cognitive function. Discussing its role in reducing depression risk and supporting cognitive functions.
