What is Vitamin D3 and Why is it Called the Sunshine Vitamin?

Vitamin D3, also known as cholecalciferol, is often called the sunshine vitamin because our skin naturally produces it when exposed to sunlight. Despite this, many people don’t get enough, especially during the fall and winter months when sun exposure is limited.

Why Vitamin D3 Matters

Vitamin D3 plays a vital role in many aspects of health:

• Bone health – Helps your body absorb calcium and maintain strong bones and teeth (NIAMS).
• Immune support – Supports the immune system’s ability to fight off infections (NIH ODS).
• Mood and brain health – Research suggests Vitamin D3 may play a role in mood regulation (Harvard School of Public Health).
• Heart health – May help support cardiovascular health, though research is ongoing (American Heart Association).

Why Deficiency is Common

Even though our bodies can make Vitamin D3 from sunlight, many factors can cause deficiencies, including:

• Living in northern climates
• Spending most time indoors
• Wearing sunscreen consistently
• Diet low in Vitamin D-rich foods like fatty fish and fortified dairy

How to Get Enough Vitamin D3

You can increase your Vitamin D3 intake through:

• Sun exposure – Short daily periods of sunlight on skin, when possible.
• Foods – Salmon, sardines, mackerel, fortified milk, and eggs.
• Supplements – A reliable way to maintain healthy Vitamin D levels, especially in winter months.
