Does Casein Protein Cause An Insulin Spike?


You will find that ingestion any type of protein will have an increasing effect on your insulin levels.

Which means that no matter what type of protein you ingest, whether it be chicken, meat, fish, beans, or protein powder you will experience an increase in insulin production. You can buy casein protein here.

How Much Of An Increase

However, the real issue is how much of an increase. Understanding this, can help you to make a more informed decision as to when you should take Casein protein or any other type of protein for that matter.

Whilst, some people think that an increase in insulin production is a bad thing, others will tell you that it can help you to preserve muscle and provide you with the right environment to build muscle, given insulin creates an anabolic environment in the body.

Which, if you’re a bodybuilder you can calculate when might be a good time to take different kinds of protein.

Heavy Training Session

For example, if you are doing a heavily weight training session in the gym, then Casein protein might not be the best choice of protein powder to take directly after a workout, given it’s slow release of protein after a workout.

A much better choice would be to ingest Whey protein with some carbs as doing so will allow the protein and the carbs to be ingested quickly into the bloodstream, provide the body with what it needs to start the muscle repair process.

Before You Go To Bed


Having said that, there is a place for Casein protein and the best use of it is usually before bed, given Casein helps to make you feel fuller, longer, and it’s slow release of vital nutrients will keep feeding your body throughout the night.

So while Casein does spike your insulin level, the level is insignificant compared to other forms of protein powders.
