How Much Caffeine In NOS Energy Drink?

QUICK ANSWER: A 16 oz can of NOS contains 160mg of caffeine.

In this article I will answer the question of how much caffeine is in NOS Energy drinks as well as go through a few other points. 

NOS is a very popular energy drink that a lot of you are familiar with.

It is one of my favorite energy drinks before a workout since it gives me both caffeine and a nice vitamin boost.

When you read NOS your thoughts might go towards cars more than energy drinks.

In that case you actually wouldn’t be too far off since the drink gets its name from Nitrous injection systems, popular in racing cars (and the Fast and Furious franchise).

But don’t worry, the drink itself does not contain nitrous.

Instead it contains caffeine vitamins and other ingredients that is claimed to give you a great tasting energy boost.

So let’s go through how much caffeine there is a NOS energy drink, and much more.

Now that you know how much caffeine there is in NOS and other energy drinks it is time to ask the question: How much caffeine should you have in a day?

Well let’s start by answering the question: Is Caffeine Bad For You?

According to MedlinePlus It is not harmful to consume up to 400mg of caffeine per day for most of us. 

This translates to just above 4 cups of coffee per day. If you consume way more than this it could lead to health issues over time. 

I remember that I consumed much more coffee when I worked as a full time barista.

When it comes to NOS energy drink you should avoid drinking more than two per day.
