Diabetes is a rapidly spreading disease, and it is essential for a diabetic to carry insulin along with him to avoid any dangerous situation. Insulin is mostly carried in a glass bottle. Suppose you are traveling, and your insulin pump runs out of insulin. It could be a nightmare for you if you didn't bring any spare insulin with you. Such a small product is of vital meaning. If you do bring it with you while traveling. It's important to keep the vial safe. Therefore, it's important to protect those small and vulnerable glass insulin vials against breaking.

What is an insulin vial protector?

 To avoid breaking your insulin bottles when they drop it's a great idea to buy an insulin protector. The great part is that it's easy to use and that you can use your insulin without removing the protective case. Your vial can drop from the stairs or great heights without any worries. It's all protected with vial protector.

An insulin vial protective cover comes in various shapes and builds. Different brands are trying to make the perfect protection for you. Most of the vial protectors are made from silicone and come in a 2 pack.

The ultimate drop challenge

I tested the vial protectors by throwing my insulin bottle on the ground. You can see this in the below movie where I am using the 4ALLFAMILY Insulin Vial Protector.

What is the best insulin vial protector?

I selected 5 vial protectors that I reviewed. All of them are great and do their job but only one can be the winner. Save your insulin from breaking.

This insulin vial protective silicone cover keeps you worry-free and prevents breaking your insulin bottles. We all know how essential it is to store hundreds of $$$ worth of medication properly, so see it as your life insurance. It will protect your vial insulin with its great protective quality.

The vial holder is designed in such a well-concepted manner that it allows you to check the label & contents of the vial at any given time. Moreover, there is an opening at the bottom that makes it easy for you to know when the vial is about to end without removing the cover.

And what I like most about this cover is that it comes with a fully covered cup. Knowing that I have to insert needles into the top of vial, I would personally be worried about the top surface not being covered and protected from dust, germs or any bacteria while the vial stays on the fridge or any cooler. So overall, protection is extremely necessary, but without cleanliness, it would not feel the same quality.

That is the main reason why is considered for me to be the best insulin protector.
