NSI Acetyl L-Carnitine HCl -- 500 mg - 60 Capsules

NSI Acetyl L-Carnitine HCl -- 500 mg - 60 Capsules

Acetyl L-carnitine (ALC) is the acetyl ester of the amino acid L-carnitine and is similar in form to the amino acid L-carnitine. It's absorbed into the bloodstream more efficiently than L-carnitine and passes more easily through cell membranes and is utilized more efficiently in the mitochondria of the cell. ALC assists in the transport of fat through the cell membrane and into the mitochondria of the cell, where fats are oxidized to produce the cellular energy ATP. ALC also promotes a healthy nervous system and supports memory. Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective 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.

"I seemed to understand things even more clearly with this Carnitine-seems like I zoomed through a book on Investing like it was nothing. I'm only in the mid-30's and I'm not yet demented -but I feel like it sometimes, hectic as life is. I don't know if I need this, but since it works well with Alpha Lipoic Acid, I decided to get both."

"I have been taking acetyl l-carnitine for years now and i noticed a difference when i first started taking it. I do wonder why you only take one of the NSI product a day while others call for 3 times a day?"

"I take this with NSI Alpha Lipic Acid have not been on this combo long enough to reach the ultimate goal but I have started off slowly on both using 1/3 to start daily and after a month will slowly increase to recommended dosage – do follow directions and cautions. For energy and fat burning."

"The association between alpha limpoic acid and acetyl lcarnitine has been well established. I use 300mg of alpha lipoic acid and 500 mg of acetyl l carnitine. For cell structure and mitichondria life it has proven to be very positive and NSI has the best value on a superior product."

"I feel this is an excellent product. I would recommend this product for anyone who is serious about training and getting rid of unwanted fat. It is especially good for those that need to cut and define in a shorter period of time and will also provide some energy as an advantage. Many people take this product along with BCAAS to get that ripped look. enjoy!!!"
