Over the years there have been many rumors about the safety of these powders, often there has been discussions on the correct daily dose, on the abuse and the relative consequences, on the impact that these had on untrained bodies or on kidneys and bones … But times are changed and today it seems clear that those who train regularly (or those who are on a regular basis to lose weight) can benefit enormously from the use of protein powder.

But it’s not enough to just buy a jar or a single dose at random, to identify the best protein powders for our body we need to know what we are doing and what we are talking about. And we are here on purpose. 

What are the best protein powders?

Protein powders have spread to the general public for several years now.

1. Yamamoto Nutrition Iso-Fuji Protein Powder

Yamamoto Nutrition’s Iso-Fuji Protein Powder are food supplements based on whey protein isolate designed to meet the needs of those who do intensive physical activity.

The powder was obtained by microfiltration, the most complex process among those normally used to obtain protein supplements and by far the best for preserving the integrity of the substances – and therefore the high quality of the product.

After an initial processing phase, the microfiltration process requires the whey to pass through a system of membrane filters from which, little by little, all unwanted particles such as lipids, lactose or minerals are eliminated.

It is thanks to this sophisticated procedure that Iso-Fuji proteins maintain all the bio-active peptide fractions of whey, for an overall protein content between 87% and 91% (respectively for vanilla and chocolate flavored products. ).

Protein rich foods vs. protein powders

It is possible to satisfy your daily protein requirement in two ways: through the foods contained in the plate or with protein supplements .

But, just as when we take vitamins, or potassium, if juices and bananas certainly cannot compete with the resource concentration of vitamins or potassium in powder or tablets. Even a balanced diet may not be sufficient to provide the correct level of protein in the body and – above all – in the case of proteins, we must consider the nutritional values.

Particularly if we want to lose weight, it is an aspect that cannot be overlooked since foods have calories while protein shakes have much less.

To put it briefly, if protein powders can help us lose weight because they don’t have many calories, food (if healthy and included in a balanced meal plan) we need to give the body the right nutritional supply.

Protein powder and individual needs

The protein whey are among the most common and popular in the market and are also the best for everyday use. They contain all essential amino acids and are easy to digest. This type of protein helps the body to have more energy and can help reduce stress levels.

The best time to take whey protein isolate or concentrate is immediately before or after training. Approximately within 15 – 60 minutes. This is because the muscle needs proteins to repair the tissues damaged by training, the micro-injuries caused by the effort, they are used to increase volume, but they also need to absorb the impact of fatigue faster and get back in shape more quickly.

Even the soy proteins are very common and widespread. They help reduce cholesterol levels and can help relieve the symptoms of menopause. They also help those with osteoporosis by helping to build muscle mass.

Among the other types of proteins we find:

  • Egg proteins : released more slowly than whey proteins, they can be consumed throughout the day. 
  • Milk proteins : support the function of the immune system and improve muscle growth.
  • Brown rice protein : 100% vegetable, they are an excellent choice for vegetarians or for those who cannot consume dairy products. They are also gluten-free.
  • Pea proteins : they are highly digestible, hypoallergenic and inexpensive.
  • Hemp proteins : They are also 100% vegetable and also contain high levels of omega-3 fatty acids.

We will analyze the different types of proteins in more detail in the course of the article but in the meantime: which types of proteins are best suited for the purpose we want to achieve?

Increase muscle mass

To increase muscle mass it is preferable to choose protein powders with high biological values ​​(the value that indicates how well our body can assimilate and use a protein). Whey protein and whey protein isolate are best for this purpose.

Lose weight

To lose weight, it is best to choose shakes with no added sugar, no dextrins or maltodextrins (sweeteners derived from starch). Also avoid protein powders with branched chain amino acids (BCAAs), as they promote muscle growth and therefore weight gain.

Vegetarian or vegan diet

If we are vegetarians or vegans and do not want to consume proteins containing milk, we can choose 100% vegetable powders such as those of soy, peas or hemp.

Diabetic nutrition

Diabetes patients should opt for no added sugar shakes (or at least not listed in the top 3 ingredients on the label). It is also best to choose low carb powders (5 – 15 grams per serving).

Limit protein for liver problems

Those with liver problems find it difficult to tolerate a high level of protein ingested all at once. We choose powders that have a lower protein content (10 to 15 grams per serving).

Avoid gastrointestinal problems

Patients with IBD or lactose intolerance should opt for protein powders that do not contain lactose sugars. Artificial sweeteners or dextrins / maltodextrins. If we suffer from allergy or gluten sensitivity, we verify that the chosen proteins are 100% gluten-free.

Be part of the monthly budget

Protein powders can be quite expensive but saving money is possible: instead of buying single-serving shakes, we buy protein powders in a jar and we measure the daily ration.

How to make the most of protein powders

A few little tips:

Recover after intensive exercise

Athletes and / or exercise enthusiasts who are always on the go should consume protein powders no later than one hour after training. It is there that the muscles react best to the proteins taken in. Using them immediately for the processes of repair and development of the muscle.

Check the weight

The ideal is to provide your body with a regular supply of protein with every meal and snack so that you feel full. 

Even if it is not possible to accurately establish, a priori, the right amount of protein to be taken at a meal, the common thought is about 20 grams.

How to make protein powders tastier

Each brand and each protein has its own unique taste. It depends on the formulation and the protein source from which it is derive. Many companies use flavorings to enhance the experience and entice the palate to feel stimulated and satisfied. Today the most used are strawberry, vanilla and chocolate – although some companies are trying to introduce more delicious alternatives.

To further enhance the flavor of the shakes. You can dissolve the powder in milk or milk replacers instead of water. The texture will be more full-bodied and the flavor will obviously be richer.

You can also put them in vegetable drinks based on fruit or fruit and vegetables, extracts, or add peanut butter, coconut, or other tasty plant substances – preferably organic.

Proteins: the allies of performance

Proteins represent about 80% of muscle mass (once water is eliminated) and muscle structure but also performance depend on them . Many professional athletes have realized that it is necessary to combine supplementary proteins with the diet. To optimize muscle size, strength and performance.

If we talk about protein powders, it is equally important to know the differences between isolated, concentrated or hydrolyzed proteins before starting to take them.

Here’s how they are classified:


Depending on how many “non-protein” parts are remove from proteins when they are transformed into powder form. Different levels of concentration can be reach. In “concentrated” proteins we find about 70 – 80% of proteins while the remaining value is composed of minerals, water, fats and carbohydrates. 


The “isolated” proteins, on the other hand, have been more “purified” of the non-protein parts and contain up to 90% pure protein but also much less nutrient levels. Whey protein isolate typically contains 86% protein. 


Hydrolyzed proteins are those proteins that contain a part of partially digested proteins such as polypeptides and peptides. While the expression “partially digested” is a bit of an impression. It is actually a very good thing as peptides are very useful in the body.

Balance a protein schedule

As we mentioned at the beginning, there are several different sources of protein to choose from, each of which has unique aspects and equally unique benefits as well.

Let’s look at them in more detail:

Whey protein

Whey protein is the most popular because it has been shown to promote muscle growth and fat loss. They digest and are absorb by the body much faster than other proteins. Are therefore preferred for post-workout (or pre-workout) consumption. 

Whey represents about 20% of the proteins contained in cow’s milk and its BCAA value is the highest of all.

Furthermore, whey is a thermogenic protein , which means that the increase in calories burned per calorie consumed is greater than other proteins, and this is closely linked to muscle protein synthesis.

Casein protein

Casein is the main protein found in milk and is a slow digesting protein, especially when compared to whey.

Depending on how much we consume. Casein can take up to six hours to be fully digest and absorb by the body. Although it has a lower anabolic and muscle-building effect than whey, casein is an excellent source of BCAAs and glutamine.

Due to its slow digestion it is preferable to take casein proteins before going to sleep or between meals, either alone or mixed with other proteins.

Milk protein

We all know milk, we consume it as a single food or we insert it in sweet and savory recipes … But how many of us knew that it is an excellent product to be consumed after an intense workout? Milk proteins contain all the essential amino acids to restore life to tired muscles and help them grow.

Milk protein isolate and concentrate are very common in protein powders, bars and other ready-to-eat preparations.  

Egg protein

Eggs are another versatile ingredient to use in cooking even though the protein in the powders is mostly isolate protein from egg white. For years there has been talk of the possible danger of eggs due to possible side effects on the heart but today these fears have been put aside and egg proteins are, moreover, an excellent choice for those suffering from milk allergy.

Not to mention that egg protein has extremely high qualitative values, is rich in amino acids and easily digested by the body.

Pea protein

It is perhaps less well known than the others but pea protein is a highly respect option particularly suitable for vegetarians. Those with allergies to eggs or milk. Not only is it hypoallergenic but it has a very high BCAA value , with a digestibility rate of 98%. What does it mean? That the body is able to use and synthesize most of the amino acids in each serving.

This is why pea protein is far superior to other plant proteins which, on the other hand, can be more difficult to digest and are not used optimally by the body. 

Goals and timing

Anyone who trains constantly in the gym. Whether they are professional athletes or just aficionados of physical fitness. Knows that daily protein intake is closely link to performance and muscle endurance.

Generally these athletes consume between 20 and 30% of total calories or 2 grams per 1 kilo of lean body mass (or the lean body mass goal). In any case the calculation will have to be customize on the daily calorie consumption. On the frequency of meals.

In addition to the supplementary protein powders. A good diet must be rich in protein and varied foods. In order to provide the body not only with proteins but also all the other essential elements for a 360-degree well-being of body and mind, including hydration.

Generally, there should be protein in every meal. Ideally we should consume 20 – 30 grams of protein (depending on the type of protein. The shape of our body approximately every 3 hours. In this way we can optimize muscle protein synthesis throughout the day.

Protein management

It is not uncommon to find products enriched with amino acids such as taurine , creatine or glycerin to increase the protein value of the powders. The problem is that these ingredients, while they have some positive effects, are not true proteins. Therefore do not have the same impact on muscle or performance as an intact protein.

So how do you know if what we are taking is a quality protein powder. If it contains “dummy” elements?

Let’s look at the leucine content on the label. The leucine is an essential BCAA that seems to aid in maximizing the mechanisms that trigger muscle protein synthesis, thus leading strength, power, resistance and dimension to muscle.

The ideal amount of leucine per serving is 2 grams. For whey protein the calculation is quite simple: a product that claims to contain 25 grams of protein. Should have 2.5 grams of leucine since whey protein has roughly 11% leucine.

Other proteins, such as casein or soy protein, contain less leucine, around 8%. 


Eating protein and some carbohydrates early in the morning helps reverse. The negative impact of the night on the muscles and stimulate MPS. The ideal is to take between 20 and 35 grams of protein at breakfast. But always calculating them on the basis of body mass, type of protein and protein goals for the day.

Before and after training

An intensive training session can increase both MPS and MPB values. The goal should be to maximize the former and minimize the latter, by consuming both proteins. Some carbohydrates either before or immediately after the work-out.

Just like for breakfast, the recommended dose will be between 20 and 35 grams of protein. 

Before going to sleep

During the night we cannot feed ourselves. For these the protein balances in the muscles slide towards the MPB values ​​to generate amino acids. “feed” the body. Consuming at least 20 grams of casein protein or a blend of casein. Whey protein, or a lower dose of protein combined with leucine. Will help your MPS values ​​stay higher even while you sleep.
