This article will discuss the key differences between vitamin D and D3, their sources, benefits and which you should look for to stay healthy.

What is Vitamin D?
From now onwards, “vitamin D” will be discussed as an umbrella term for fat-soluble secosteroids responsible for calcium, magnesium, and phosphate intestinal absorption enhancement. Further, it works in bone density maintenance, immune system support, and enhancing mood. However, that is how the confusion rolls- two major types are D2, called ergocalciferol, and D3, called cholecalciferol.
- Vitamin D2 (Ergocalciferol): Found in plants such as mushrooms and some fortified foods.
- Vitamin D3 (Cholecalciferol): Being formed from, or present in: animal sources such as fatty fish and egg yolks, and sunlight.

Key Differences Between Vitamin D2 and D3
While vitamin D and D3 both keep you healthy, their sources, potencies, and effectiveness vary.
- Source
- D2 is derived from plants and fortified food.
- D3 is derived from animal products and sunlight.
- Potency & Absorption
Scientific research has shown that D3 is a superior vitamin for raising and maintaining vitamin D levels in the bloodstream. It has been demonstrated that D3 raised serum 25(OH)D levels significantly more.
Duration in the Body
Since D3 remains active longer, this is why it should be chosen over other types for long-term supplementation.
Vitamin D Liquid vs Pill: Which One Is Better?
While buying a supplement, you might’ve come across various kinds like the vitamin D liquid and the pill. Let’s see how they stack up:
- D vitamin liquid is typically given preference for people who have a hard time swallowing pills, for infants, or for children. It is also believed that it gets absorbed faster.
- Pills or capsules for D vitamins are convenient, portable, and often contain a precise dosage.
So, on the whole, both forms work-the most important thing is consistency and dosage rather than which way the supplement is taken.
Conclusion
So, what exactly is this difference that gets the two terms confused? Let’s keep it short here:
- Vitamin D is an umbrella term.
- D3 is the most common and potent form used in supplementation and is preferred by many.
- D2 is less potent and generally comes from plants.
- D3 is very efficient at raising the level of vitamin D in your system; therefore, it is often recommended by doctors.
When comparing vitamin D vs D3, especially in the case of supplementation, always read the label and get vitamin D3 unless your health practitioner says otherwise. Liquid vitamin D or pill, D2 or D3, whichever one you choose will cater to your needs and lifestyle.
