Why let the manufacturer boil the life right out of your whey? This is exactly what happens to the great majority of whey, turning them from a superfood to a hideous industrial processed food. Yes, the typical whey that most builders use is likely excitotoxic and you can read about in my link on Whey and Excitotoxins for more information. Whey is a powerful protein that does not boost IGF-1 nearly as much as other animal proteins, due to its relatively low methionine levels, and also boosts the super-antioxidant glutathione. Anything that boosts glutathione is likely to have powerful anti-aging properties and so, hopefully, that has your attention as well.
But the key is that you must buy undenatured whey, which usually means that it has been extracted via CFM (Cross Micro Filtration) processes that are gentle on the proteins. CFM means very low heat and thus very low excotoxicity. And, yes, undenatured whey is rich in muscle-building BCAA's (Branched Chain Amino Acids).
NOTE: I am currently consuming a Whegan Diet. That's my name for someone who eats vegan but includes Undenatured Whey for its powerful superfood properties. (I am doing this because I had a high PSA reading and am trying to bring that down.) If you are eating almost entirely plant-based, one serving of whey typically has about 20% of your calcium RDA. Nice!
There are now quite a few CFM wheys out on the market and I wanted to give a quick review of some of the ones I have tried:
1. Whey Factors. This whey out of Canada clearly states on the bottle "Non-Denatured, Microfiltered, No Growth Hormones". The label also clearly states that there are no artifical preservative, color or sweeteners and no wheat or yeast or added sugars. What is remarkable about this product is that it has a pretty good flavor and yet the ingredients clearly state that it is just whey and natural chocolate flavor inside. (It may contain "traces of soy.") It has a somewhat sweet taste, so I'm not quite sure how they pulled that off but kudos to them for making a decent-tasting product.
The container that I bought ahd12 ounces and had 17 servings of 15 grams of protein, i.e. 255 total grams of protein. However, Amazon has a larger 2 lb container: Whey Factors, Natural Double Chocolate Flavor, 2-Pound.
2. Grass-Fed Whey Protein. This is another product that seeks to be as natural as possible and clearly states on the label:
"Grass-Fed Whey is minimally processed and low in lactose, sodium and cholesterol. Plus, our microfiltered, undenatured manufacturing process protects the beneficial co-factors and nutritents in whey."
They also only use grass fed cattle that have not been given synthetic hormones such as rBST and rBGH. The container that I got was a 12.7 ounce can containing 12 servings of 20 grams or 240 grams of total whey protein. As far as taste, Grass-Fed Whey does a nice job with having a sweet, but not too sweet vanilla flavor. It derives this from the following indredients: "whey protein concentrate, natural vanilla flavors, stevia leaf extract, sunflower lecithin." If you're interested in checking out the product, this one is also avaiable on Amazon: Grass-Fed Whey, Vanilla (12.7 oz)
3. Biochem Whey. Biochem Whey is the CFM product that I have used the most. I have already given in coverage in my page a A Review of Undenatured Biochem Whey.
So the bottom line is that there are plenty of whey products out there that are very natural and will likely help boost your efforts at building muscle, immunity and detoxification. I see guys on The Peak Testosterone Forum doing some strange things from time to time trying to "detox." If you want to detox, is there any better way than boosting glutathione, the body's natural detoxer? I doubt it and I have many ideas, including whey, in this link: Natural Ways to Increase Glutathione.
