If you are one of those dedicated gym-goers who's already eating plenty of animal and plant proteins daily, kudos to you for taking muscle gains seriously!
Have you ever wondered just how much protein your body can actually absorb?
For years it was believed that the body could not absorb more than 30-40 grams per one sitting, but more and more studies show that this is not true – you can absorb a much larger amount.
Now, I know you're no beginner in the protein game, so let's skip the basics and dive right into the details.
How Much Protein Can Your Body Absorb? (Situations Explained)
It would be great if I could tell you exactly how much protein your body can absorb, but no one knows for sure.
Yes, I know you have probably heard self-proclaimed fitness experts who claim to know precisely how much the body absorbs, but I am guided exclusively by science.
And science says this amount varies depending on the situation and many other individual factors, including age, activity level, gender, and so on.
After A Workout
Many of my clients wanted to know how much protein they can consume after a workout. This is natural because we are all hungry after a workout and want to fuel our muscles in the best possible way to repair muscle damage caused by lifting weights.
Although a post-exercise anabolic window is mostly a myth, your body is certainly primed to utilize protein for muscle repair and growth immediately after resistance training is completed.[1]
My recommendation to clients and you reading this is to consume a high-protein meal or snack containing between 20 and 50 grams of protein.
It's not like you can absorb in one sitting more protein after a workout than usual, but that amount will immediately support your recovery.
And that's not all.
A significant amount of protein will prevent binge eating and food cravings, which often happen even to elite athletes when they are tired. If you eat 10 oz steak or drink two scoops of high-quality whey protein powder, you won't crave an unhealthy candy bar.
In One Hour
Data on protein absorption in one hour are more precise - the body can digest approximately 8 to 10 grams of protein per hour.[2]
The amount is certainly not the same for a healthy person and someone who faces malabsorption due to inflammatory bowel diseases, for example. However, we can use it as a benchmark.
It is excellent that we know that the body absorbs 8 to 10 grams of protein per hour, but this is also the reason why there are many misconceptions and myths about this topic.
Many people think this implies that the body cannot absorb more than 20 to 30 grams per meal. The truth is that it will just take more time. So if you take 50 grams of protein, the body will digest it for about 5 hours, keeping you full.
Slower absorption of protein than carbs is the primary reason why meat keeps you full longer than pasta.
In One Meal
Theoretically, you can ingest 100 grams of protein or more in one meal and have the body absorb it all.[3]
While it may be tempting to consume a large amount of protein in a single meal and support muscle growth that way, I do not advise you to do so.
Stick to the range I already mentioned, which is between 20 and 50 grams.
Consuming protein beyond this range may not provide additional benefits in terms of muscle protein synthesis, and you may experience side effects or even gain unwanted pounds.
It is unlikely that the body will store excess protein as fat, but it is possible if you are in a caloric surplus.
An exception can be intermittent fasting. So, if you only have 1 or 2 meals daily, go for more per meal.[4][5]
In One Day
The small intestine is the star of the show because that's where most of the dietary protein is absorbed. It has another great possibility, which is to store extra protein and release constituent amino acids only when you need them. It’s like an amino acid pool where all the excess amino acids go.
Why are we telling you all that?
Because it is the key to answering how much protein the body can absorb in a day. The answer is practically unlimited or as much protein as you consume.
Of course, things are not black or white.
Nevertheless, since the body can use those essential amino acids, including famous branched-chain amino acids (BCAAs) from the small intestine, most of the protein you take in will eventually be absorbed.
I'm not advising you to be immoderate in protein consumption. I'm just telling you that the amount of protein the body will use is incomparably higher than it was once thought.
Also, your body doesn't just use protein to build muscle tissue. This is not even the most important function of amino acids in the body. Proteins are used for many purposes, including DNA and RNA repair.
Recommended Protein Intake Per Day
The general recommended protein target intake is 0.5 grams per pound daily.
You will undoubtedly find advice to consume less protein than that, for example, 0.3 grams per pound, but I think 0.5 grams is the minimum. After all, proteins are essential.
Yet, after years of working with the most diverse clients, including those who want to lose weight, change body composition, and achieve muscle gain, I know no general recommendation is very accurate and protein requirements will vary.
That's why I will separate several groups by activity level, goal, and health status and give you a more personalized recommended total protein intake.
If you want to be 100% sure you are consuming the ideal protein dose, consult a doctor or a dietician who will consider all factors.
What Are The Effects Of Consuming Too Much Protein Powder?
Although high-quality protein powder and other protein supplementation will help you reach your daily protein goals, if you consume it too much, you will encounter more or less serious side effects. Moderation is the key to good health and fitness results.
These are the most common ones:
Weight Gain
Proteins do not provide as many calories as fats, but consuming excessive amounts of protein powder can lead to weight gain too.
When you reach an overall caloric surplus, you will gain weight, regardless of the source of the calories. It is undoubtedly better to drink whey protein isolate or slow-digesting protein such as casein than to eat junk food, but the bottom line is the same if the calorie intake is too high.
Kidney Problems
No, protein powders and a high-protein diet are not villains that will destroy your kidneys. If you are healthy, nothing terrible will happen long term.[7]
However, high-protein diets increase the workload on the kidneys as they work harder to metabolize and eliminate the byproducts of protein breakdown. This can potentially lead to kidney problems in individuals with pre-existing conditions, so be careful.
Dehydration
Protein metabolism requires water, meaning excessive protein powder without sufficient hydration can cause dehydration.
It is essential to hydrate not only because of a high total daily protein intake but in general.
If you feel thirsty right after protein powder consumption, it's not due to the whey protein concentrate or whey protein hydrolysates itself but artificial sweeteners, thickeners, and other added ingredients.
Nutrient Deficiencies
If protein powder becomes the sole or predominant source of protein in your diet, you will miss out on the benefits and nutritional diversity that whole foods offer.
I know protein shakes are very convenient, but whole food sources provide not only protein but also a wide array of essential vitamins, minerals, and other nutrients.
So, it would be best to have a balanced healthy diet to avoid nutrient deficiencies.
Digestive Issues
Digestive issues triggered by protein powder are not severe, but you definitely want to avoid them.
Bloating, gas, and stomach discomfort are just some of the symptoms that all of us who actively consume protein shakes have experienced. Choose those with digestive enzymes added for better protein digestion.
Constipation can also occur, but diarrhea is more common, especially if you are lactose intolerant. In that case, pea protein, hemp protein, soy protein, and other plant-based proteins are good alternatives.
Amount Of Protein The Body Can Absorb Questions
The recommended daily intake if you want to build muscle mass is around 0.7 to 1 gram per pound of body weight. So, if you weigh 180 pounds, you'd want to consume roughly 130 to 180 grams of protein daily. That amount can be even higher if you are a professional bodybuilder or athlete.
Generally, it takes around 1 to 3 hours for protein to be digested and absorbed. The speed at which the body absorbs protein varies depending on factors like the protein source, the presence of other nutrients, and the condition of your digestive system.
No, high-protein meals of 50 grams of protein are not necessarily too much for one meal. While there is no set limit for protein intake per meal, spreading it throughout the day may be more beneficial for muscle protein synthesis and, thus, muscle building.
However, if consuming 50 grams of protein in one meal aligns with your overall daily protein goals and fits your individual preferences, there's no harm in doing so. Just make sure to consume enough protein throughout your day.
Summary – Spread Your Protein!
There's no magic number or universal rulebook for how much protein your body can absorb in one go.
Most likely, healthy adults can successfully absorb even over 100 grams of protein in one sitting. Still, if you consume too much, you can gain weight and experience side effects.
So, instead of overwhelming your stomach with a massive amount of protein, spread it throughout the day.
Another important aspect to consider is the quality of your protein sources. Not all proteins are created equal.
