Vitamin A is essential for a healthy immune system, and taking a vitamin A supplement can help support immune function. Vitamin A is fat-soluble, meaning it's stored in the body and so doesn't need to be taken every day.

However, when you are looking to boost your body's defense system, finding the best vitamin A capsules can make all the difference. Not all vitamin A capsules are created equally though, so it’s important to know the differences between them. There are two types of Vitamin A supplements available: preformed Vitamin A (retinol) and provitamin A carotenoids (beta carotene). Preformed vitamin A (retinol) is typically more effective since it's already in its active form from food sources such as fortified milk products, eggs and liver.

But consuming too much preformed Vitamin A can be toxic and may cause serious side effects such as skin rashes, headaches or even death in extreme cases. Provitamin A carotenoids on the other hand, must be converted in the body before being able to use for its health benefits. These provitamin forms of Vitamin A have fewer associated risks than retinol but are also slightly less potent.

That’s why it’s important to choose wisely when selecting a vitamin A supplement – some contain both retinol and provitamin forms of Vitamin A while others contain only one or the other. To make things easier, here is a list of five of the best Vitamin A capsules that will help you keep your immune system strong.
