The complete guide to protein supplements

Protein is extremely important. It’s what makes up your muscles, your skin, and most of the mechanisms inside your cells. It gets used up, and it has to be replenished. But not all of us can manage a high-protein diet every day. 

That’s where protein shakes come in. They supply extra protein in a small package to help you reach your daily protein intake goals. Usually, they have low calories and little to no extra sugar, so they can provide just protein and nothing else.

So, how many protein shakes can you drink in a day? How many should you drink? In this article, we’ll help you find out everything you need to know about reaching your goals with protein shakes. 

How much protein should men have daily?

It can vary quite a bit, but the daily value of protein, which is what they use when calculating nutrition labels, is 50 grams of protein per day. The recommended daily intake, a slightly more flexible measure, is about 45 to 60 grams per day. 

If you want to get more specific than that, you can calculate your personal protein intake. Men are recommended to get 0.35 grams of protein per pound of body weight per day or 0.8 grams per kilogram. So, if you weigh 200 pounds, you should aim for 70 grams of protein.

However, it’s important to keep in mind that these are the general recommendations to avoid a protein deficiency. If you exercise regularly or want to build muscle, you should aim for 1.8 to 2.2 grams of protein per kilogram of body weight.

Are protein shakes a good source of protein?

A lot of popular protein shakes contain about 20 grams of protein, with 100 to 200 calories and little to no sugar. They’re a good source of the protein you need without breaking your diet. Some protein shakes have up to 40 or 50 grams of protein. 

For comparison, a large chicken breast contains 30 grams of protein. This means that most protein shakes are almost as good a source of protein as a piece of chicken, although they contain less fat and fewer calories.

It is usually recommended that you drink only one or two protein shakes a day. For example, if you weigh 200 pounds, your minimum protein intake should be 70 grams per day. If you drink a protein shake with 20 grams of protein three times, that’s 60 grams or almost your entire protein intake. Unless you’re trying to replace all your protein intake with protein shakes, this is too much, and it is recommended that you get a decent amount of your protein from whole foods as well.

In fact, even that calculated daily intake can change depending on your activity level. Most people only need to drink protein shakes on days when they’re working out, either before or after the workout. Extra protein intake can help your muscles grow, but most people don’t require daily protein supplements. 

Protein powder vs. pre-made protein shakes

Protein powder can be mixed into water, a smoothie, or any other liquid. Protein powders usually also contain the same amount of protein, about 20 grams per scoop. Some of them are sweetened, and some of them rely on whatever you mix them into for their flavor. 

The major upside of protein powder is that you can combine it with other things, like blending it with other superfoods for a custom protein shake. This also gives you more variety and the ability to customize your drinks. In other words, protein powder is very flexible and customizable, but pre-made protein shakes are more convenient since you don’t have to mix them up. 

Are there side effects to overconsuming protein supplements?

It is possible to eat too much protein, and there can be side effects from higher-than-necessary protein intake. For example, you may experience constipation or other digestive effects because protein is harder to digest than the other macronutrients — carbohydrates and fat. Eating too much protein can also lead to weight gain, just like eating too much of anything else because there is an excess of calories.

Protein source alternatives

Meat is the most obvious source of protein — anything from steak and chicken to fish is a good source of protein and energy. Chicken and fish like tilapia are high-protein and low-fat, which makes them often a better choice than beef or pork. Milk and eggs are also good protein sources. Options for vegetable protein include peas and beans, soy, and protein-enriched wheat products like pasta.

How do you know if you’re protein deficient?

If you’re not getting enough protein, you’ll often lack energy, and you won’t see the muscle gains you expect. You might also notice your hair, skin, and nails lacking luster and strength because protein contributes to their health. 

How much protein per day is safe?

You usually shouldn’t go above the recommended intake for your weight. The general maximum is 2.2 grams per kilogram of weight, or 1 gram per pound, unless you’re doing really intense work like bodybuilding.

I put the INNODIGYM OMNI X1 Pro to the test for 30 days: Can it replace the gym?

I love the convenience of not having to travel to the gym and being able to use all of that energy on a solid home workout instead. Whether it’s for privacy or convenience, many people are switching to smart home gyms that offer multiple workouts in one machine. As a health and fitness writer, I can honestly say that not all smart home gyms are created equal.

Recently, I put the INNODIGYM® OMNI X1 Pro to the test for a whole month, and this machine is a beast. Once you know what you’re doing, you’re off to the races, or should I say, off to your very own high-tech home gym? I remember the first time I ever set foot in a gym, and all the different machines seemed a little daunting. That said, it was pretty easy learning how to use the OMNI X1 Pro, and it’s all right there in one good-looking machine. Overall, I’m impressed with the quality, craftsmanship, and user-friendly nature of the OMNI X1 Pro, especially the straightforward setup.

Three Aletha tools for smart home gym and spa

The gym and I have always been at odds. From long commutes to memberships that feel like a life sentence, the extra effort chips away at my goals. Outdoor workouts offer a little less friction until they don’t. Weather fluctuations, crowds, and pretending I don’t mind people watching me contort into strange positions takes its toll as well. My solution? The smart home gym. 

These days, at-home workouts don’t require massive cages, rows of dumbbells, and complicated trainers that collect dust. Sleeker design and newer technology have unlocked a new world of at-home fitness that looks as good as it works. Best of all, restorative spa devices joined the party too, so you can decompress after a long workout just steps away from your gym setup.

Fitness 101: The perfect bench press with fitness expert James McMillian
Adult, Male, Man

Every man has a similar thought when they first get up to go to the gym. We see it in movies. We see it in TV shows. The bench press is the number one representation of strength. When the movies or TV shows want to showcase their character’s strength, they send them to the weight bench with piles of plates on each side of a bar. The result of that is that when we head to the gym, the bench is the first destination. So, we need to make sure every man is armed with the knowledge and confidence. Men have to learn how to do a bench press and how to do it well.

That is why I reached out to one of my favorite fitness experts for our next edition of Fitness 101, James McMillian. As the President and Head Coach of Tone House, New York City’s premier athletic conditioning studio, he’s spent over a decade in the fitness world. From personal training and coaching high-energy group workouts to bringing people together through fitness experiences across the country, he is likely the busiest father and entrepreneur in New York. He is also in better shape than all of the Avengers and dresses better to boot. So, I will let him take the lead on teaching us about the bench press.
