Take this with carnitine
to grow muscle and
increase your energy
A couple weeks ago, I showed you how the supplement carnitine can slow aging. This amazing nutrient can greatly slow your muscle loss, increase your energy, and make aging a little easier. Well, new evidence suggests carnitine isn't the only natural product that can do all this.
A recent study found that whey protein can build muscle in those over 65. This study compared whey protein with taking amino acid supplements, both essential amino acids and non-essential amino acids. That means the scientists were looking to see if improvement came from the amino acids or something more special in whey.
Here's what they found: Whey protein was superior in building up key muscle mass indicators. Furthermore, whey improved their insulin response compared to both the amino acid groups. So whey protein might help preserve your muscle mass as you age.
Whey has all the essential amino acids. While the individual amino acids didn't help, all of them together did. Getting improvement in insulin response means that whey protein must have other beneficial effects. I suspect it's how the amino acids are arranged (linked together).

Amino acids supplements provide just that, isolated amino acids. Proteins link together amino acids in specific sequences. Scientists call these sequences peptides. The amino-acid sequence of peptides provides for unique and magical properties.
For example, the linkages in whey are loaded with an unusual, but critical peptide sequence involving glutamate and cysteine. This peptide sequence is crucial raw material for the all-important body detoxifier, immune enhancing, and antioxidant glutathione. I've written about this wondrous substance repeatedly.
Whey peptides may have other unknown benefits. After all, milk is what baby mammals use to grow healthy muscles and immune systems. So there may be other immune and growth peptides in it.
Now, you may know that I'm not a fan of milk in most instances. That's because its major protein, casein, is highly allergenic and in some cases, possibly outright damaging. But milk's other protein, whey, is much different, and I often recommend it as a supplement. And I've seen it work miracles in some cases.
Combining whey protein with a carnitine supplement (500 mg, two to three times daily) might be your best bet. Be sure that your whey supplement is "undenatured." That means it's not heated, which destroys its biological activity. I currently recommend Immunopro powder, one to two scoops per day. It is available readily online and at most health food stores.
Yours for better health and medical freedom,
