BEWARE OF PROPRIETARY PROTEIN BLENDS

BEWARE OF PROPRIETARY PROTEIN BLENDS

If your protein powder blend is not Pro JYM then it's a proprietary blend!

You have heard me caution you against supplements that use proprietary blends and spiked protein. To refresh your memory, a proprietary blend is any supplement that doesn't list the precise dose of every single active ingredient it contains. For more on protein spiking, watch this video. And here's an article and a video on proprietary blends.

Blended Secrets

When it comes to proprietary blends, you likely think about preworkout supplements, fat burners, postworkout supplements, testosterone boosters, and the like. You probably didn't know that almost all protein powder blends are proprietary blends! This is the unfortunate truth.

Take a look at the label of any protein powder blend, except Pro JYM. We'll look at the Pro JYM label later. A protein powder blend is a protein powder that uses more than one form of protein. For example, it can be a blend of whey and casein protein, or a blend of whey, casein, and egg protein. Or it can even be a blend of different whey proteins, such as a blend of whey protein concentrate and whey protein isolate. What you will realize when you take a close look at protein powder labels is that 99% of the protein powder blends sold on the market today do not list the exact amount of each one of those proteins. All they list is the total amount of protein in the Supplement Facts panel. In the "Ingredients" list (image below) you will find each type of protein used, but that's it. All they tell you is the type of protein used, but not the amount of each one. To me, that is simply ridiculous!

Here's an example of where you will find the ingredients in your protein powder:

Pro JYM, on the other hand, lists the actual amounts of each protein on the FRONT OF THE BAG. Check it out:

Let's say you bought a protein blend that was whey and casein. If it only listed the total amount of protein per serving as 20 grams and only listed the two types of protein in the ingredients list, then you have no idea how much of that 20 grams of protein comes from whey and how much comes from casein. And that should be a concern to you, a huge red flag.

Pro JYM is the ONLY non-proprietary protein powder blend available. Take a look at the label of Pro JYM by clicking here. You don't even have to turn the bag of Pro JYM around and find the Supplement Facts panel because I list the exact amount of each type of protein in Pro JYM right on the front label so that it's plain to see. That's the only way that you will know what makes up the 24 grams of protein in each serving of Pro JYM: precisely 7.5 grams of whey protein isolate, 7 grams of micellar casein, 7 grams of milk protein isolate, and 2.5 grams of egg white protein. Add that up and it totals 24 grams.

Since milk protein isolate is about 20% whey and 80% micellar casein, on the back of the Pro JYM bag I further give you the exact amount of whey, casein and egg protein in grams. That 24 grams of protein per serving of Pro JYM comes out to be:

9 grams of Whey Protein
12.5 grams of Micellar Casein
2.5 grams of Egg White Protein

I believe that you should know how much of each protein you are getting. I know I want to know that type of info. And since you are also consuming this product, it's only fair that you also know exactly how much of each protein you are consuming. The other reason I do it is so that you can see that when you add each protein together, it totals the 24 grams of protein listed in the Supplement Facts Panel. That way you know that I did not do any protein spiking. If you do not know what protein spiking is, click here to read my eye-opening article on a major problem with protein powders.

Percent Perceptions

When I tell people that Pro JYM is the only non-proprietary protein powder blend available today, some state that a few other companies are already doing what I am doing. But they're not. A few other companies are listing the percent of each type of protein that is in their protein blend. For example, a protein powder blend that is whey, casein, and egg protein might list that it's composed of 40% whey, 40% casein, and 20% egg protein. But that is NOT listing the exact amount of each one of those proteins.

If a company is so proud of their protein blend, then why wouldn't they list the amount of each protein in grams?! You wouldn't buy a preworkout supplement that lists the ingredients as percentages. Could you imagine if a preworkout supplements listed it's ingredients as 30% BCAAs, 20% creatine, 20% beta-alanine, 29% citrulline malate, and 1% caffeine?! You would not by it! At least I hope you wouldn't be dumb enough to buy it. So why should you not expect much better for protein powder blends? If they only list the percent of each protein source and do not list the precise grams of each protein source, then that protein powder is a proprietary blend. Sorry, but it's true.

Some would argue that listing the percent of each protein source does tell you how much of each protein is in there. But it does not. For example, let's say that a protein powder blend lists 20 grams of protein per serving. For simplicities sake, let's say it's a whey/casein blend and it lists 50% whey protein and 50% casein protein. That should mean that 10 grams is whey and 10 grams is casein. The key word here is "should". So does it contain 10 grams of whey plus 10 grams of casein? I don't know because they didn't list he grams. But I do know that you have to wonder why they wouldn't just list the grams of each protein the way that I do. It's very simple to do.

Why is Pro JYM the ONLY protein powder blend that lists the grams of each protein source? One reason may be that the percent of each protein source listed in these other protein powder blends does not represent the total protein listed on the Supplement Facts Panel. One reason for this could be protein spiking. Again, be sure to read the protein spiking article I included the link to above.

If a protein powder that lists 20 grams of protein on the label is spiked with 5 grams of taurine. Then it's only really 15 grams of true protein and 5 grams of taurine. That means that that 50% whey and 50% casein represents 15 grams and each equals 7.5 grams (half of 15) and not 10 grams. So that could be one reason that a company would put the percent of each type of protein versus listing the exact grams of each protein.

Another issue is that some companies simply lie on the label. Some protein powders that have been independently tested were found to contain significantly less total protein than listed on the Supplement Facts panel and significantly more carbohydrates than listed. If this was the case, then you could understand why the company would only want to list the percent of each type of protein versus the grams of each type of protein.

Pro JYM is the only protein powder blend that lets you know exactly how much of each type of protein you are getting in every serving. And you can be sure that the 24 grams of protein listed as total protein in the Supplement Facts panel is true because you can see that when you add up each type of protein they equal 24 grams.

With Pro JYM you can rest assured that there is no protein spiking and no lying. Just quality that you can count on. Quality that you can literally COUNT on!
