Question for the pros. Wondering about this supplement.
 

I've recently begun taking this supplement.

http://www.bodybuilding.com/store/4ever/isolate.html

As far as the carbohydrates or the small amount of lactose that is in it, I'm not concerned.

However some reading has led me to believe that it's possible Glutamic Acid is capable of pushing someone out of ketosis.... has anyone else read this, or can provide me with a second opinion? Are there any other items in this product that might push me out of ketosis?

To be honest, I'd like to continue taking it if I could, I have definitely felt less ache in my muscles after working out from it. I use it immediately after the workout as a recovery assist.

The ingredient I thought might cause a concern is Acesulfame K.

I found this:

"Acesulfame K

Acesulfame Potassium (K) was approved for use by the FDA as a safe artificial sweetener in July, l988. It is a derivative of acetoacetic acid. Unfortunately, several potential problems associated with the use of acesulfame have been raised. They are based largely on animal studies since testing on humans remains limited. The findings showed the following:

Acesulfame K stimulates insulin secretion in a dose dependent fashion thereby possibly aggravating reactive hypoglycemia ("low blood sugar attacks").

Acesulfame K apparently produced lung tumors, breast tumors, rare types of tumors of other organs (such as the thymus gland), several forms of leukemia and chronic respiratory disease in several rodent studies, even when less than maximum doses were given. According to the Center for Science in the Public Interest, it was petitioned on August 29, l988 for a stay of approval by the FDA because of "significant doubt" about its safety.

Dr. H.J. Roberts, Aspartame (NutraSweet) Is It Safe?, Charles Press, page 283/84."

And this...

"As with aspartame, saccharin, sucralose, and other sweeteners that are sweeter than common sugars, there is concern over the safety of acesulfame potassium. Although studies of these sweeteners show varying and controversial degrees of dietary safety, the United States Food and Drug Administration (USFDA) has approved these for use as general-purpose sweetening agents. Critics of the use of acesulfame potassium say the chemical has not been studied adequately and may be carcinogenic, although these claims have been dismissed by the USFDA[4] and by equivalent authorities in the European Union.[5]^ http://ec.europa.eu/food/fs/sc/scf/out52_en.pdf"

Never heard of the International Food Information Council before, but here's what they say about Ace-K: http://www.ific.org/publications/bro.../acekbroch.cfm

From that website regarding safety of Ace-K:

"How much acesulfame potassium may people consume?

The FDA sets an Acceptable Daily Intake (ADI) level for many food ingredients that it clears for use. The ADI represents the amount of an ingredient that a person can safely consume each day over their entire lifetime. For acesulfame potassium, that amount has been set at 15 milligrams per kilogram (mg/kg) of body weight. For a 60 kg (132-pound) person, this corresponds to 900 mg of acesulfame potassium every day for a lifetime or approximately 200 grams (one-half pound) of sugar equivalent each day. At current average usage levels in beverages, for example, this amount would correspond roughly to two gallons of beverage daily."

As for L-Glutamic Acid... if that can knock us out of ketosis we're all in trouble.

"Excellent sources of glutamic acid include meat, poultry, fish, eggs, and dairy products, as well as some protein-rich plant foods."

IMHO, I don't see any problem with you having a scoop of this after your daily workout. It's 23 grams of protein for 100 calories and there's NO SOY in it. The only suggestion I might make would be to add some fat to this "snack" to keep the protein/fat balance that's so important when low carbing. A few nuts or an ounce of cheese, for example.

Tril

Oh I eat a normal dinner when I get home. This shake I get right out of the locker. I pour the water in, shake it, chug it, take my shower, and get on the motorcycle to go home, where I have my regular dinner.


As far as aspartame or Ace K, im not concerned about carcinogenic aspects, and the insulin raising effect of artificial sweeteners don't seem to hurt me too bad.

What I can read about Ace K is that it's used in very small amounts to supplement the main sweetener, which in this case is sucralose.

To be honest, ive always rather wanted aspartame than splenda, since splenda is rather high on the glycemic comparative to sugar.
