My Story

01-06-99 As a clinical scientist and a certified nutritionist, I probably would have never tried Calorad® if it had not been recommended to me by my best friend, Scott.

01-10-99 Purchased and started using Calorad® for the first time.

01-17-99 Day 7 - Weight loss ...4 lbs.

01-24-99 Day 14 - I lose 4 more lbs and decide to become a distributor!

02-10-99 Day 30 - I finish my first bottle and lose .. another 4 lbs for a total of 12 pounds!

02-10-99 Day 30 I have lost almost 12 pounds and over two and a half inches off my waist within my first four weeks on Calorad®.

02-10-99 Day 30 My wife, Lynn, loses three pounds and a total of five inches in the same time period.

02-24-99 Six weeks on the product. I experience increased energy, improved sleep, and several lipofuscin deposits (age spots) on my hands recede and totally disappear.

03-03-99 My wife, who previously suffered from frequent and rather severe bouts of insomnia, now 'sleeps like a baby.'

04-07-99 My teenage son and daughter also start to use the product and experience similar weight loss and muscle toning.

05-11-99 My sister loses 10 pounds and two dress sizes in three weeks, and she loves the product.

11-07-99 I decide to spread the word online, and establish my nutrition advisor website.

As a clinical scientist with a doctorate in nutrition, I can truly say that Calorad® is one of the best diet products I've ever seen!

In the 4 1/2 years since, we have sold over $1 million dollars of Calorad® online, and have seen many great Calorad® success stories.

Sincerely, Lt. Col. Steven Petrosino, USMC (Retired)

A series of clinical studies and complementary laboratory experiments has shown that aging is associated with a progressive decrease in plasma cysteine and intracellular glutathione concentrations. This decrease leads to (and can be viewed as a manifestation of) age-related oxidative stress. Cysteine and glutathione concentrations are particularly low during the night and early morning hours, i.e. during periods of starvation. Several clinical studies have also shown that cysteine supplementation on top of the regular diet ameliorates several aging-related processes and improves amongst other parameters skeletal muscle functions and infl ammatory cytokine levels. Most of these studies have been performed with N-acetylcysteine (NAC). This was the best choice for this purpose because the free amino acid cysteine is not very stable and cysteine-rich proteins such as IMMUNOCAL® contain various different amino acids and would not have been helpful in studies designed to identify cysteine as the most important amino acid in this context. The search for the best strategy to supply additional amounts of cysteine to the average consumer is now raising a very different and practical question. Not surprisingly the answer is different.

Let us compare NAC with IMMUNOCAL®. NAC has some adverse effects which are not shared by IMMUNOCAL® and which render NAC unattractive as a source of cysteine over long periods of time. In addition, there are studies to suggest that dietary cysteine from any source is converted within the blood into its less accessible derivative cystine and within the liver into its breakdown product sulfate unless it is rapidly cleared from the blood by protein synthesis in skeletal muscle and other tissues. The undenatured whey protein IMMUNOCAL® provides all protein-forming amino acids and is known to stimulate rapid protein synthesis within less than 2 hours. This process allows the body to store cysteine until it is recovered by regulated protein breakdown during periods of starvation, i.e. during the night and early morning hours. IMMUNOCAL® is clearly superior to NAC in stimulating this process of cysteine storage.
