There are several indications of possible liver problems; these include yellowish discoloration of your skin‚ nausea‚ chronic abdominal pain in the upper right portion of your torso‚ unexplained weight loss‚ and continual tired feelings. The liver is mainly responsible for vital roles such as metabolizing fats and carbohydrates‚ storing vitamins and iron‚ getting rid of toxins in the bloodstream‚ and the production of bile—an acid that is critical for the digestion of food and elimination of waste products. If you have a damaged liver‚ you have a potential risk of developing gallstones and feeling discomfort. If you are experiencing more than one of the symptoms of liver damage‚ consult your heath provider immediately and consider amino acid supplements like Metabolic Maintenance’s NAC 600 mg.

NAC is a special dietary amino acid that aids the body in producing gluthathione and other important antioxidants. Its main ingredients are:

  • N-Acetylcysteine‚ a compound that is a potent antioxidant also known for its liver-protecting properties.

  • L-leucine—an amino acid that encourages muscle production and aids in storing glycogen‚ a form of glucose.

Aside from helping your liver stay healthy‚ NAC 600 mg may help lessen the severity of symptoms related to the flu‚ bronchitis‚ and allergies. This supplement may also be effective for detoxification.

NAC by Metabolic Maintenance is free of preservatives and excipients‚ and is derived from vegetable sources. The recommended dosage is one capsule daily‚ preferably between meals‚ unless otherwise instructed by your healthcare professional.

Metabolic Maintenance vitamins and supplements are time-tested and physician-approved. All products are truly excipient-free‚ meaning that they have no fillers like cellulose or silicon dioxide that other manufacturers often add to products. Using only the purest ingredients and cutting-edge medical technologies‚ Metabolic Maintenance vitamins and supplements come in tinted glass bottles to best store them without losing their potency and effectiveness.

      The delivery was 2 day. Thank you!!

      from scotch plain on 10/15/2011
      Amino Acid provides relieve from common allergies and cold symptoms. I even used NAC 600 mg by Metabolic Maintenance a few years ago when I had strep throat. I have recommended to over twenty or more people. One of the jars I purchased was for my professor at college. He has been suffering from allergies.


      Everything, I try to take one a day. My daughter could not get ridge of a cough so I open up the capsule and put it in a little water for a week and she felt better.
