Whey isolate is one of the most widely used supplements in strength training. There is much debate about the best time to take it. Does your shake really need to be finished within 45 minutes after your workout? In this article, you’ll learn what does and does not matter.
What is whey isolate?
Whey isolate is whey protein from which most of the fat, carbohydrates, and lactose have been filtered out. What remains is a powder with a high protein content and few calories per serving. Protein contributes to the growth and maintenance of muscle mass.
The most important thing: your daily total
For building muscle, the amount of protein you consume throughout the day matters most. Strength athletes often aim for 1.6 to 2.2 grams per kilogram of body weight. The strict 45-minute 'anabolic window' is outdated: whether you drink your shake immediately after training or an hour later makes little difference for most athletes. Timing is therefore mainly a matter of convenience.
Three convenient times
1. After your workout
After a tough session, you often don’t feel like eating a full meal yet. A shake is then an easy way to get some protein in.
2. At breakfast
Many breakfasts contain little protein. A shake alongside or mixed into your oatmeal helps make up the difference.
3. Before your workout, if you haven’t eaten for a while
If there are more than three to four hours between your last meal and your workout, having a shake beforehand can be convenient. It is easy on the stomach.
Spread your protein intake throughout the day
It is practical to spread your protein intake across three to five meals, with 20 to 40 grams per meal. This helps you reach your daily target without making one meal especially large.
