Do you actually know how much protein powder per day experts recommend? Although protein shakes have become part of everyday life for many people, most do not know exactly how much powder is okay—or whether there can even be "too much" of a good thing. With this article, you'll find out exactly that and can calculate how much protein powder per day is individually right for you.
Your knowledge to go: How much protein powder per day?
-
There is an upper limit for protein powder: Where this limit lies depends on your diet, your needs, and your individual tolerance. Find out more in the article.
-
For many people, 1–3 protein shakes per day is a suitable amount. Alternatively, the corresponding amount of protein powder can also be used in recipes.
-
With our guide, you can find out how many protein shakes can be a practical addition for you.
-
If you want to gain or lose weight or do intensive exercise, protein powders can be an interesting option. Find out more in the FAQ.
The upper limit: How much protein powder per day at most?
Even though we love Vetain protein powder, we have to be very clear that—as with everything in life—there can also be too much protein shakes . I'll explain exactly where this limit lies now:
There are 3 things that determine how many grams of protein powder per day are right for you:
-
The total amount of protein consumed
-
Your eating habits
-
Digestion & Tolerance
Let's go through the individual points one by one:
Total amount of protein
Can you consume too much protein? Yes. Even though we mostly read about "more protein" in everyday life, there is in fact also such a thing as "too much" protein. And especially with protein shakes, you can reach this "too much" faster than you might think. Professional associations in Germany consider up to 2 g of protein per kilogram of body weight to be harmless. So, if you weigh 70 kg, for example, that's 140 g of protein per day—as a maximum.
For comparison: Like many protein powders, Vetain's vanilla protein powder provides 21 g of protein per serving, while some other powders contain up to 30 g of protein per serving.
If you are thinking now: Easy, depending on the protein powder, I can drink 4–6 protein shakes a day, I am afraid I have to disappoint you. Even though I would personally love to drink that many Vetain shakes, unfortunately, that is not possible. Because you also consume protein through other foods. With a normal, balanced diet without a focus on protein, this amounts to around 0.8 g / kg of body weight per day. For our 70 kg example person, that is 56 g. So there are "only" 84 g of protein left for shakes. That, in turn, amounts to about 3–4 shakes*.
Go ahead and calculate this value for yourself. This is the basis for figuring out how much protein powder per day is right for you.
Eating habits
Protein powders are great when ...
... they optionally supplement your meals.
... you enjoy drinking a shake before or after exercising.
... you enrich your muffins with protein powder.
... you mix a breakfast protein shake with oats, banana & co.
But: If ...
... someone can think of nothing but protein,
... it is no longer possible to imagine a single meal without some powder,
... a meal feels incomplete and unhealthy to you simply because it does not contain protein powder,
the boundary between normal eating habits and rather problematic behavior patterns is very thin.
As soon as protein powder becomes not a "can" but a "must" for you, and a low-calorie protein shake feels more like a normal meal than an exception, I would urge you to pay more attention to yourself and your eating habits. Especially in the high-protein bubble, it is very important to keep in mind that protein powders are dietary SUPPLEMENTS, meaning they do not replace a balanced diet.
It is difficult to say how much protein powder per day is critical in this context, as the threshold is different for everyone.
Reminder: Protein powders are a practical tool for everyday life, but not a substitute for a balanced diet. And if the question of how much protein powder you have already consumed today and how much more you still need to consume occupies your thoughts from morning to night, it no longer sounds like an optional supplement.
Digestion & Tolerance
Not everyone tolerates shakes equally well. This depends on the protein shakes themselves, as well as individual tolerance and gastrointestinal health. Especially if you are just starting to drink protein shakes, your body may need a little time to adjust to the higher amount of protein. Otherwise, too much protein at once may feel uncomfortable for some people and lead to stomach aches & co. These are then typical protein powder side effects.
For some people, it may therefore make sense to start with one shake per day and then gradually increase the amount if needed.
If you experience symptoms after just 1 protein shake, it may also be that the ingredients simply aren’t right for you, and another powder may be more suitable.

You can already see that the limit for how much protein powder per day is okay is entirely individual. So I can’t simply give you a specific number that works for everyone—if you need help finding the right amount for you, feel free to contact us.

How many protein shakes per day are beneficial?
So, now we know the maximum amount of protein powder you should consume per day. But how much protein powder per day is actually beneficial? Or, in other words: How many protein shakes should you drink per day to get the most out of them?
This is also truly individual and depends on you, your habits, and your goals—and, of course, your diet as well. If you do a lot of exercise, you need more protein than if you are not very active. If your diet is otherwise low in protein, more protein shakes may make sense than for someone who already gets a lot of protein from their diet.
In general, 1–3 protein shakes per day is normal. (Of course, 0 shakes is also perfectly fine.) Important: Not as a meal replacement, but as a supplement! This can make a significant contribution to your protein intake. It can be particularly practical if you train actively or have trouble getting enough protein through your diet.
Calculator: Your perfect shake amount
This is how you can find the perfect amount of protein powder for you:
-
Calculate your protein requirement (You can find out how to do this in the linked article)
-
Track your diet without shakes for a few days and note how much protein you consume from your diet on average.
-
Subtract the amount of protein you’ve consumed from your daily requirement, and you’ll know how large your “protein gap” is. If you want to and tolerate them well, you can fill this gap with protein shakes.

And believe me: If you calculate how much protein powder per day is individually right for you, it is much more meaningful than a simple figure on the internet. So the effort is worth it. ;)
How much protein powder per day in specific situations?
We have now answered the question of how much protein powder per day is suitable for the general population. But what about specific goals or life situations? In the FAQ below this article, we explain how protein powder fits into losing weight, gaining weight or exercising.

Conclusion
There is no set amount of protein powder per day that is okay or not okay. It is much more about finding a good balance and an amount that is individually right for you.
Therefore, you will not find an answer on the internet to the question "How many protein shakes should you drink per day?" that is precisely tailored to you. Because no one knows you, your diet and your needs better than you do.
Always keep in mind: Protein can be fun, make your everyday life easier and add variety – but it should not restrict you.
PS: With all the information about the amount of protein powder, one question remains unanswered: Do you need protein powder at all? You can find out that and more in the article: What are the benefits of protein powder?
And if you can't get enough protein, our article "How many protein bars per day?" is sure to be interesting too!
