Introduction
There is often confusion surrounding the differences between vitamin D and vitamin D3. Are they the same thing? Is one better than the other? It’s important to understand the differences between these two nutrients to ensure that you are meeting your body’s needs. In this article, we’ll explore the differences between vitamin D and vitamin D3, which one you should be taking, and how to choose the right supplement.
Understanding the Differences Between Vitamin D and Vitamin D3: An In-Depth Overview
Vitamin D is a fat-soluble vitamin that is essential for strong bones, immune function, and overall health. There are two types of vitamin D: vitamin D2 and vitamin D3. Vitamin D2 is primarily found in plant foods, while vitamin D3 is produced by the skin when exposed to sunlight and is also found in animal-based foods.
Vitamin D3 is the active form of vitamin D and is often referred to as cholecalciferol. When vitamin D3 is produced by the skin or ingested through food, it must go through a series of steps in the liver and kidneys to become active in the body.
The main difference between vitamin D and vitamin D3 is their source. Vitamin D can come from both plant-based and animal-based sources, while vitamin D3 is primarily found in animal-based sources or produced by the skin through exposure to sunlight.
Vitamin D vs. Vitamin D3: Which One Should You be Taking?
The recommended daily intake of vitamin D for adults is 600-800 IU, while the recommended daily intake of vitamin D3 is 800-1,000 IU. However, the appropriate daily dosage of vitamin D or vitamin D3 can vary depending on a person’s age, gender, health status, and other factors.
It is important to speak with a healthcare provider before starting any new supplement regimen, particularly if you have a history of kidney or liver disease, high blood calcium levels, or take medications that can affect vitamin D metabolism.
In general, vitamin D3 is more effective at raising the body’s levels of vitamin D than vitamin D2. If you are deficient in vitamin D, your healthcare provider may recommend taking a vitamin D3 supplement to raise your levels more effectively.
Factors That May Affect the Decision
When choosing between vitamin D and vitamin D3 supplements, there are several factors to consider:
- Your current vitamin D levels
- Your diet (whether you consume animal-based foods or not)
- Your exposure to sunlight
- Your age, gender, and health status
If you are deficient in vitamin D, vitamin D3 may be the best choice for you. If you follow a vegan or plant-based diet, you may choose to supplement with vitamin D2 or increase your sun exposure to obtain vitamin D3 naturally.
Potential Risks of Taking Too Much of Either Vitamin
While vitamin D is essential for overall health, taking too much of it can be harmful. Vitamin D toxicity can cause hypercalcemia (elevated calcium levels in the blood), which can lead to kidney damage, nausea, vomiting, and other symptoms.
The tolerable upper limit (TUL) of vitamin D for adults is 4,000 IU per day. Taking more than this amount can increase the risk of toxicity.
All You Need to Know About Vitamin D and Vitamin D3 Supplements
There are several forms of vitamin D and vitamin D3 supplements available, including capsules, tablets, gummies, and liquid drops. When choosing a vitamin D or vitamin D3 supplement, look for a product that is third-party tested and has been certified by organizations such as the United States Pharmacopeia (USP) or ConsumerLab.com.
It’s important to note that vitamin D supplements should be taken with a meal that contains healthy fats, such as avocado or nuts, to aid in absorption.
Possible Side Effects
While vitamin D supplements are generally safe when taken as directed, they can cause side effects in some cases. Common side effects include nausea, vomiting, constipation, and increased thirst.
If you experience any adverse effects from taking a vitamin D supplement, discontinue use and speak with your healthcare provider.
How to Take Supplements Safely
To avoid the risk of taking too much vitamin D or vitamin D3, it’s important to follow the recommended dosage guidelines and speak with your healthcare provider before starting any new supplement regimen.
If you are pregnant or breastfeeding, speak with your healthcare provider before taking any vitamin D or vitamin D3 supplements. Children and teenagers may also need a different dose of vitamin D than adults.

Specific Uses of Each Vitamin
Vitamin D2 is primarily used to treat and prevent rickets, a bone disease that occurs in children due to vitamin D deficiency. Vitamin D3 is often used to treat vitamin D deficiency in adults and is also used to treat osteoporosis and other bone diseases.
Who Would Benefit from Taking Vitamin D or Vitamin D3
People who are at risk of vitamin D deficiency or have low levels of vitamin D in their blood may benefit from taking a vitamin D or vitamin D3 supplement. This includes people who do not get enough sun exposure, follow a strict vegan or plant-based diet, are obese, or have a medical condition that affects vitamin D absorption.
