Whey Protein Powder

Soy vs. Whey Protein Powder – Your Go-To Guide!

These days you rarely walk into a gym without seeing someone mixing up protein powder in a shaker or walking out eating a protein bar. It’s hard to imagine not following up a great workout without a protein supplement, which helps to repair and build lean muscle after physical activity. With protein powder being a common form of supplementation after exercise, a question many have is which protein powder is for me? Well look no further, we’ve created a go-to guide to help you more effectively decide whether a whey or soy protein powder is more suited to you.

Whey Protein Powder

What is it?
Whey protein is considered a complete protein as it contains all 9 essential amino acids which includes the 3 branched-chain amino acids (BCAA) leucine, isoleucine and valine. BCAA are the first amino acids the body uses to rebuild and repair muscle during periods of exercise and resistance training, hence essential for many sporting athletes and fitness enthusiasts.1 If you’re looking for a whey protein powder, check out the XSTM Sports Nutrition range which offer a protein rich supplement providing 30g of protein per serve.

Whey protein has been studied for promoting muscle growth and improving athletic performance. Taking whey protein after exercise may have benefits in both men and women, in terms of improving protein oxidation and blood levels of essential amino acids. Overall, short-term studies have suggested that whey protein increases muscle mass and strength.2

For some, the downside to whey protein is that it contains lactose, therefore not suited for vegetarians, vegans and the lactose intolerant. However, this is where soy protein can be beneficial.

Who may be suited?

  • Anyone doing strength and resistance training sessions and anyone wanting to increase their dietary protein.
  • Anyone wanting a low fat, well absorbed protein source.
  • Those interested in a complete, lean protein source to help build muscle mass.

Soy Protein Powder

What is it?
Soy protein powder is made from soybeans, a member of the pea family. Unlike other vegetable proteins, soy protein is a complete protein source containing all 9 essential amino acids. Soy protein is neutral in taste making it extremely versatile to add in many ways into anyone’s diet and daily routine. From shakes to meals, the uses for soy protein powder are endless.
