Warning – Don’t Over-Pay for Whey Protein & Why Proprietary Ingredients Should be Avoided
Whey protein is an excellent source of cysteine, the amino acid that is necessary for glutathione (an important anti-oxidant) production and encourages increased tissue levels of glutathione.
Some supplement manufacturers sell their whey protein supplements at a very high mark-up and claim their product is special in some way and backed by clinical research. They claim that their whey protein is an effective cysteine delivery system.
So, I took a closer look at one. After reviewing several research studies they provided, I was not able to see any evidence that their product has benefits beyond other forms of whey protein. When asked further questions, they were not willing to divulge the amount of cysteine in their whey protein, claiming this information is proprietary. Maybe they don’t know. Maybe they just add cysteine to plain old whey protein. Maybe their product contains more than other whey proteins. Perhaps it contains less. Who knows? We sure don’t.
I also asked about pesticides and hormones. They do not test to ensure that their whey protein is pesticide and hormone free and it is not obtained from organically raised dairy cows.
Based upon the information provided, here is what we know:
- their supplement is expensive
- it works like other whey protein powders and cysteine containing supplements
- How much cysteine it contains
- If cysteine levels vary substantially from one batch to the next
- How it compares to other cysteine supplements
- How it compares to other whey protein supplements
- If it contains pesticides & antibiotics
