It isn’t uncommon to be slightly confused by the three different types of protein on the market. Different people tell you which ones are better, and when you should be taking them. Isolate, Whey, and Casein actually do have their differences. Hopefully, by the end of this article, you’ll be a protein expert, because we’ll be taking you through their functions, why you should take each one, and when they’re appropriate.
We’ll start with the normal Whey Protein, as this seems to be the most common one people use. Whey will be quickly digested. Within 20 minutes, it will be flowing through your veins, and within the hour, it should be fully metabolized. This is a positive, because the quicker you get the protein to the muscles, the better, and more quickly they recover. Whey is a by-product of cheese or milk production. It is generally the most affordable protein, but it isn’t necessarily the best quality for you, and your body. Though it is pure, it is not even close to being the most pure protein on the market.
Now, we’ll discuss Whey Isolate. Isolate is the next step up in purity compared to normal Whey protein. It often doesn’t contain lactose, meaning lactose intolerant people usually don’t have any issues with taking Isolate protein. It is just as fast acting as whey, maybe even more so. It is extremely ideal to take as a post-workout protein shake. Actually, it’s ideal to take all the time. The reason people don’t, is probably a money issue. Due to the purity, and the fact it’s such good quality, it tends to be slightly pricey, whereas Whey is the basic, so it’s quite a bit cheaper. If you have the money, we definitely recommend you take isolate all the time, so you can get the best possible results.
Casein, is most commonly known as the slow acting protein, or bedtime protein. The reason it’s usually taken at bedtime is because it’s much slower to metabolize than Whey and Isolate proteins. This allows your body to have a supply of protein for much longer than the other two protein types. It’ll allow your muscles fuel to recover throughout the night, so your recovery will be more efficient, and complete by morning. It as well is quite expensive, but it’s worth it if you have the money. It will last quite a while, as you are only taking it once per day.
To summarize, Whey protein isn’t a necessary part of your daily diet. If you can afford it, take Isolate throughout your day. It’s more pure, and better quality. Casein is to be taken before you fall asleep, due to the fact it’s slow to metabolize.
