Vitamin D3 vs Vitamin D2
One of the most prevalent dietary deficiencies in the world today is vitamin D insufficiency. Many people still struggle to maintain appropriate vitamin D levels even in this day and age of supplements, particularly those who live in areas with little sunlight or spend most of their time indoors.
When you take supplements, they frequently have to choose between vitamin D2 and vitamin D3. Everyone is confused of what actually meets their needs because the labels are identical, the dosages frequently overlap, and most bottles just read "Vitamin D."

When the skin is exposed to sunshine, particularly UVB rays, our bodies can produce vitamin D. However, its natural production is frequently limited by modern lifestyles, indoor jobs, sunscreen use, seasonal variations, and pollution. Because of this, supplementing practically becomes essential.

Vitamin D2, also known as ergocalciferol, is a plant-derived form of vitamin D.

Where it’s commonly found
Vitamin D2 was one of the earliest forms used in supplementation. While it does raise vitamin D levels, research over the years show that there are better supplements which are more efficient.
What Is Vitamin D3 (Cholecalciferol)?
Vitamin D3, or cholecalciferol, is the form naturally produced by the human body when skin is exposed to sunlight.
