 A Vegans Plant Based Protein Powder Complete Buyers’ Guide

A soy protein powder is a supplement that makes use of the protein that is from soybeans. Soybean belongs to a leguminous family. It is rich in protein and vital amino acids that are excellent for muscle building & gaining mass.

  • Soybeans are mainly used as meal replacements for those individuals on a strict vegan diet.

Soy is often processed and stored as soy protein powders packs for easy availability and convenience. Most eas soy protein powders offer up to 20 grams of protein which is enough to supplement your protein intake.

Types of soy protein

Soy protein packs and sells in two forms; the soy protein concentrate and soy protein isolate.

Soy protein concentrate

This type of soy protein is manufactured when soy is defatted leaving the white substance in soy in its place. The white substance is then subjected to ethanol extract to neutralize its PH levels. The content is then solid to departments and distribution.

The soy concentrate has low levels of isoflavones because of its ethanol extraction. For this reason, soy concentrate is a smart choice for men worried about side effects of isoflavones.

Soy protein isolate

The soy isolate is produced from the white substance remained in the soybean after the defatting process. The concentrated protein is further processed through centrifugation which can extract the highest percentage of protein by weight.

Protein isolate contains high levels of isoflavones because the step of ethanol extraction is skipped during its preparation. Therefore, this is not the best choice of soy protein for men who worry about their semen quantity and quality.

How different is soy protein from whey protein?

Whey and soy protein are the most common two protein supplements mainly used by bodybuilders or those who intend to add some weight. Understanding the difference between these two types of protein will help you make a better decision when it comes to choosing which one to buy.

Whey is one of the dairy products of grass-fed cows. It is a by-product in the process of cheese making. Whey protein is important in maintaining the bone structure and putting on weight. A compound called leucine found in whey protein helps in muscle repair and recovery after intense training.

Is whey safe? Soy is a good lactose free protein powder option

Even though whey protein provides, you with the essential ingredients you need for muscle building. There are several concerns that the protein supplement contains toxins from copper that has been associated with several gastrointestinal conditions.

Whey is also a dairy product and will cause allergies to any individual that is lactose intolerant. The most common allergies include bloating, cramps, headaches, and general body weakness.

Which one should you buy whey or soy?

The best protein supplement for you will depend on your needs. Whey has been highly considered the best when it comes to muscle building, even though, soy is also equipped with enough protein to help maximize body building process.

  • Soy is a perfect choice for individuals with lactose intolerance or those willing to cut down on their animal products intake.

We recommend that you use soy and whey together when you want to see great bodybuilding results. This is because whey protein is rich in Branched Amino Acids (BCAAs) while soy protein is abundant in high levels of arginine an amino acid that stimulates muscle building. Glutamine is also found in soy; this amino acid facilitates fast muscle recovery and repair.

Here is what to look into before buying a protein supplement of your choice:

1. Dietary restrictions

People with lactose intolerance may not have a good time using whey protein because of the allergies associated with the protein. It is vital to exercise precaution when testing whey protein when you are prone to allergies.

2. Amino acid profile

Different protein supplements contain different amino acids. The levels of leucine, methionine, and lysine are more in whey protein than in soy protein. Soy protein contains more arginine and tryptophan amino acids.

3. Nutritional considerations

Several minerals play a role in muscle building and recovery. Some are vitamin B2 which also helps in the breakdown of protein. Zinc, on the other hand, is required for producing muscle-building testosterone. All protein powders are fortified with minerals and vitamins. It is, therefore, essential to have a look at the nutritional value at the pack before buying one.

4. Taste and texture

Taste and texture is a question of personal preference. Most soy protein powders are creamy and smooth while others are grainer with a strong flavor. Remember that the additives and stabilizers significantly affect the taste and texture of the protein powder. You may choose to buy unflavoured soy protein so that you have a chance of adding your flavours.
