While there are a lot of cheap alternatives, the protein that I recommend is Whey Cool from Designs for Health. It is organic and non-denatured and comes from grass fed cows.
There are many processes to create whey protein, such as cross-flow filtration, microfiltration, ultrafiltration, hydrolyzation or ion exchange methods but all of these methods create MSG excitotoxins.
What most people don’t know is that high quality non-denatured whey protein tastes pretty good without flavoring. Because of that, Designs for Health hasn’t had to add exuberant amounts of sugar like many other companies.
While I wouldn’t choose Whey Cool as my only source of nutrition, it does containg a complete amino acid profile and promotes glutathione synthesis.
I keep in stock Whey Cool unflavored and vanilla. Sensitive patients usually only test for unflavored but many times people can get away with vanilla which is a little more pleasing to the taste buds.
You can buy Whey Cool online or if you come to my office I can sell it to you in person. I do sell it significantly cheaper to my patients.
