In this post, we are going to uncover those little-known secrets so that you can learn more about the supplements you are spending your hard earned money on.

1. Whey Peptides Are Sometimes Extracted For Additional Profit

Whey protein naturally contains whey peptides. Peptides are considered to be the most beneficial part of whey protein and are responsible for increasing your muscle pumps and it can even contribute to a stronger immune system.

Unfortunately, some companies that sell protein supplements are quite greedy – they extract as much whey peptides from their protein supplements as possible and sell a denatured version of the protein. They then sell the extracted whey peptides separately.

2. There’s No Major Difference Between Grass-Fed And Grain-Fed Whey Protein

When whey protein is made, protein is extracted from the milk of cows and isolated from any fats and carbs. A lot of whey protein powders cut all the fat from the milk during this process. A lot of companies promoted their whey protein supplements as “grass-fed” and claims that their powder is better than the “grain-fed” ones – they also charge much more for their product. Unfortunately, the only difference between the starting product (the milk) of grass-fed and grain-fat is the fat content, which means you will not obtain a better quality whey powder when opting for “grass-fed”.

3. Your Supplement May Contain Animals

Many years ago, it was discovered that the fur of some animals is naturally high in keratin, a protein that is often used to produce certain amino acids and even protein. Unfortunately, this process is used by many suppliers of BCAAs and other amino acids, which means if you are using a protein supplement that is enriched with amino acids, there’s a really good chance that the amino acids were derived from animal fur, duck feathers or even from human hair.

4. You Might Just Be Paying Extra For Some Print Work

In the United States, the rules that regulate Genetically Modified Organisms found in food is quite lenient when compared to other countries.

Countries like New Zealand are much stricter and demands that certain animals, such as cows, are raised in a free-range environment without any GMO. Unfortunately, some companies may fool you by stating that the product is GMO-free, but it still contains GMO. Look at the label before you pay a higher price for your GMO-free products.

5. If Your Brand Manufactures In The U.S., Then Your Supplements Isn’t Undenatured

The word “undenatured” is often found on certain products, such as milk and, of course, your favorite bottle of whey protein supplements.

If these products were produced in the United States, then you should know that the supplier is lying to you. U.S. law requires the pasteurization of all whey protein products – even the products that claim to be cold filtered has gone through the pasteurization process.

6. You May Find A Cheaper Product That’s Exactly The Same

Many brands who stock whey protein supplements source their whey protein from the same manufacturer, but distribute the supplement under a different brand name and, of course, at a different price tag.

The next time you shop for a whey protein supplement, be sure to compare the content of the supplements, the different brands, and the price. Chances are, you will likely find a different brand from the one you use that’s cheaper, but still contains exactly the same content.

7. Whey Protein Is Not Exactly An Amino Acid

Amino acids are known as the building blocks of protein, but the end product, being protein, isn’t really an amino acid itself.

Some manufacturers, however, use this factor to their advantage and include amino acids in their whey protein supplements to save on costs. These, however, aren’t always as effective as a pure protein supplement.

8. Hydrolyzed Collagen Isn’t As Effective As You Might Think

Many protein supplements promote an ingredient called “hydrolyzed collagen” and claims that it will provide a significant improvement in your muscle growth.

This, however, isn’t really true as hydrolyzed collagen doesn’t have useful nutritional content that can promote muscle growth. In fact, scientific studies have found that hydrolyzed collagen doesn’t have any positive effect on the development of lean muscle mass.

9. If You’re Lactose Intolerant, You Should Be Careful

As much as 65% of the adult population worldwide is lactose intolerante or are unable to fully digest lactose. This condition can be troublesome and be consuming any product that contains lactose makes the condition even worse.

Whey concentrates, one of the main types of whey protein supplements, contain lactose. This means that individuals who are lactose intolerant may be sensitive to certain whey protein powders.

10. Whey Protein Powder Is Like Powdered Milk

Whey protein is separated from another protein known as casein and lactose after milk has been pasteurized. The substance is then purified and dried, which results in whey protein powder.

Powdered milk is actually made in a very similar way, but contains additional content, such as vitamins, minerals, and fats (that occur naturally in milk).
