Protein vs Amino Acids: Difference Explained

Protein vs amino acids? These are popular supplements among fitness enthusiasts, but many people are unsure about their differences. Here we compare and contrast the two to help you determine whether you should take amino acids or protein.

Protein vs amino acids – Protein powder contains whole proteins derived from various sources to help you meet total daily protein requirements. Amino acids are the building blocks of protein and can be supplemented to target individual amino acid needs.

What Is Protein Powder?

Protein powder is a dietary supplement that is made from various sources, such as milk, soy, and pea.

What Are Amino Acids?

Amino acids make up protein. There are 20 different types, nine of which are essential and must be obtained from the diet.

Protein vs Amino Acids

Protein powder encompasses a complete amino acid profile compared to individual amino acid supplements. Milk and soy are two common protein powders.

Milk protein can be divided into whey (20% of milk protein) and casein (the remainder). Whey can be further subdivided into concentrate (29-80% protein by dry weight) and isolate (more than 90% protein).

Soy protein can be categorized into flour, concentrates, and isolates, each containing 50%, 70%, and 90% protein, respectively.

Amino acids are sold individually as supplements or there is also protein powder with amino acids. Individual or combinations of amino acids have been theorized to have ergogenic potential. For example, branched chain amino acids (leucine, isoleucine, and valine) support protein synthesis, energy production, and attenuate fatigue during exercise. Taurine has been shown to significantly increase VO2 max. An ‘amino acid cocktail’ containing the essential amino acids consumed within 1–3 hours before or following exercise may help support muscle protein synthesis.

1. Processing

Protein powder is created through a process called filtration, which separates protein from other components such as fat and carbohydrates. The resulting protein is then dried and ground into a powder form.

Amino acid powders are created through a process called hydrolysis, which involves breaking down the protein into its individual amino acids using enzymes or acid hydrolysis. The resulting amino acid mixture is then purified and dried to create a powder form.

2. Average % Of Protein/Carbs/Fats:

The composition of pro t ein, carbohydrates, and fat for protein powders vary depending on the amount of processing and type of protein powder. Amino acid powders, on the other hand, are typically 100% protein.

For the common whey protein:

Whey powder: typically contains 11-14.5% protein, 63-75% lactose (carbohydrate), and 1-1.% milk fat
Whey concentrate: typically contains 25-89% protein, 10-55% lactose, and 2-10% milk fat
Whey isolate: typically contains 90% or more protein, 0.5% lactose, and 0.5% milk fat

3. Price Range:

The price range for protein powders and amino acid powders can vary depending on the product. Generally, protein powders have an average cost of around $30–$50 for a 1–2 lb container. Amino acid powders can range from $15–$55 for a 0.5–1 lb container.

Protein powder vs Amino Acids: Summary

In summary, if you’re wondering if you should take amino acids vs protein, both can be beneficial for muscle growth, recovery, and repair. Protein powder can help you meet total daily protein requirements whereas amino acids can supplement specific amino acids that may be lacking.

1. Pros and Cons of Protein Supplements

Positives:

Convenient.
Effective for muscle building, repair, and recovery.
Maintains or increases satiety, which can help with weight management.
Easy to control carbohydrate and fat content (compared to whole foods).
Variety of flavors and types available.
Good value for money for a large number of products.

Could be better:

Digestive issues may occur depending on the protein source and/or any other ingredients in the supplement.
High-quality protein powders can be expensive compared to whole food sources of protein.

2. Pros and Cons of Amino Acid Supplements

Positives:

May be beneficial for muscle building and repair.
Convenient, especially for people who may have difficulty getting enough through diet alone.
Certain amino acids, such as BCAAs, may help to reduce muscle soreness and fatigue after exercise.
Not always a pleasant taste and smell.

Could be better:

May not provide significant benefits compared to consuming a well-balanced diet or a quality protein powder.
Depending on the brand or product, can be more expensive than protein supplements.

Protein vs Amino Acid: When to Use Each

Protein supplements are ideal for people who need to increase their overall daily protein intake or for people who struggle to meet their protein needs through whole foods alone.

Amino acid supplements may be useful for people who require specific amino acids due to dietary restrictions that may make it difficult to get enough through food sources alone. For example, those who follow a plant-based diet may be low in lysine, methionine, isoleucine, threonine, and tryptophan. Amino acid supplements may also be preferred by experienced athletes who are trying to get even small benefits from dietary changes.

How to Pick Between Protein and Amino Acid?

1. Diet Type

If you follow a vegan or vegetarian diet, amino acid supplements may be more suitable to help you get an adequate amount of all amino acids. If you consume animal-based protein sources, then protein supplements are appropriate to supplement meeting your overall daily protein requirements.

2. Goals

If your goal is weight loss then a supplement with a high protein-by-weight ratio that is minimal in fat and carbohydrates can help. Amino acid supplements will typically have a high protein-by-weight ratio. If you’re looking for something that supports muscle building and recovery, then a protein supplement that includes a slightly higher amount carbohydrates (and consequently a lower protein-by-weight ratio) would be more suitable.

3. Label Transparency

Look for supplements with transparent labeling that lists the ingredients and their respective amounts. Products that are third-party tested would have a certification on the label. This protects you as the consumer as the product is tested for harmful levels of contaminants and ensures supplements contain the listed ingredients and nothing else.

4. Value for Money

Consider the overall value for money based on the serving size, protein content, and price per serving. Keep in mind that a higher price doesn’t always mean better quality, so look for products that meet your protein or amino acid needs and fit your budget.

So What to Take?

There are a plethora of options out there when it comes to protein powder and amino acid supplements. Here are two that we have reviewed and could suggest for you to consider:

1. Recommended Amino-Acids – BulkSupplements

CHECK LATEST PRICE

BulkSupplements has a ‘BCAA 3:1:2 powder’, which is a branched chain amino acid supplement that contains a 3:1:2 ratio of L-leucine, L-isoleucine, and L-valine. It is suggested to take ½ tsp once or twice a day, 30 minutes before a workout. This is an adequate dosage to optimize training adaptations.

BCAAs are often found in animal protein and if overall daily protein requirements are met, then taking any additional BCAA has not been found to be beneficial since improvements in strength and hypertrophy require meeting the requirements for all the essential amino acids. However, it has been suggested that the RDA for leucine for sedentary individuals should be 45mg/kg/day and higher for active individuals. Owing to the high leucine proportion in this supplement, it may be a convenient way to meet higher leucine requirements all in one source.

This supplement has good ingredient quality and value for money.

2. Recommended Protein – Future Kind +

CHECK THE PRICE ON FUTUREKIND

CHECK LATEST PRICE ON AMAZON

If you are looking for a plant-based protein option, Future Kind + offers an organic vegan protein composed of organic non-GMO pea protein isolate that is offered in a vanilla or chocolate flavor. There is 20g protein (~73% protein-by-weight), 0g fat, 1g carbohydrate (0g added sugar, sweetened with stevia), and 85kcal in a one scoop serving. Therefore, suitable for anyone looking to cut weight.

Pea protein is low in some particular amino acids such as methionine (an essential amino acid) and cysteine; therefore, it is important to ensure consumption of other sources of these amino acids (such as brown rice protein). This product has a good taste, a creamy non-chalky texture, mixes well, and does not contribute to bloating.

FAQ

Do Amino Acids and Protein Go Together?

Yes. Some people might use protein powder as a general source of protein, and then supplement with specific amino acids that are lacking elsewhere in the diet.

Do I Need Amino Acids if I Take Protein? Can I Take Amino Acids Instead of Protein?

If you are already consuming enough protein from a variety of sources, then additional amino acids are generally not necessary. A diverse protein intake can provide you with a complete amino acid intake. However, for athletes with long and hard workouts, taking extra BCAAs with a high leucine proportion can provide some performance, recovery, and immunity benefits. For people whose diets are poor in certain amino acids, supplementation may also be beneficial.
