The benefits of L-Leucine Ethyl Ester:  Amino Acid Esters are amino acids with an ester molecule attached. Esters are organic compounds that are formed by esterification, which is the reaction of carboxylic acid and alcohols. Esters are organic compounds that help shuttle the amino acid across lipid membranes of the gut and directly into the bloodstream for direct transport to your cells. This prevents the amino acid from being destroyed in the gut and drives more of the free form amino acid directly into muscle tissue where it can be more efficiently used for its intended purpose.

Free form amino acids have inherent limitations such as limited absorption through the intestine. Whereas amino acid esters can pass through the intestine largely intact, regular free form aminos can be significantly degraded in the intestine, leaving only trace amounts of the ingested dose active. Because of the rapid breakdown of some amino acids in the intestine, its beneficial effects can be limited. Ethyl ester amino acids are thought to have a much better absorption rate and a longer half-life in the body than regular free from amino acids because it is slightly more lipophilic.

Certificate of Analysis Proves Quality & Freshness:  Always know the expiration date of a supplement before you purchase. If the manufacturer won't give you the expiration date and a Certificate of Analysis than beware. Many online venders sell expired or nearly expired products which they get on closeout from distributors who can no longer sell them to stores. NutraBio.com guarantees that this product is from the freshest and purest raw ingredients available and was packaged within the last two weeks. Click on the red "Purity & Freshness Seal" at the top of the page to view the actual Certificate of analysis.

Beware of inferior packaging:  How your supplements are packaged can be just as important to their freshness and quality as the ingredients themselves. All NutraBio supplements are packaged in HDPE (high density polyethylene) bottles. These bottles keep moisture vapor and harmful UV rays out, protecting the freshness and integrity of their contents. HDPE bottles are 400% more effective as compared other brands currently using PET (polyethylene terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

Beware of companies claiming to save you money by putting their supplements in plastic  baggies. These are usually companies operating out of their house or small facilities that do not have the proper equipment and technology to manufacture and package supplements under clean, sanitary conditions as required by the FDA and CGMP guidelines. LDPE (low density polyethylene) clear baggies allow UV light, air and airborne contaminants to come in contact with their contents, which can degrade active ingredients and deteriorate their freshness.
