PERQUE® LLC introduces PERQUE L-Histidine Guard™.

PERQUE LLC announces the launch of PERQUE L-Histidine Guard, an essential amino acid for gut and immune support.

ASHBURN, VA – PERQUE LLC announces the launch of PERQUE L-Histidine Guard, an essential amino acid for gut and immune support. Amino acids are building blocks for proteins and essential for growth, tissue repair, enzyme production, and metabolism. Being an essential amino acid, L- histidine is not synthesized endogenously by the body and needs to be obtained through dietary protein sources or appropriate supplementation.  

Low histidine levels can result from limited protein intake, gastrointestinal dysfunction, or various salicylate or steroid medications, and can lead to anemia, joint pain, fatigue, brain fog, and symptoms of anxiety and depression. Supplementation can help resolve these issues, restore optimal stomach acid production and stimulate the secretion of gastric juices such as pepsin and hydrochloric acid. As an antioxidant, l-histidine can provide an anti-inflammatory effect while empowering the body to boost its inherent antioxidant pools. Histidine is the precursor for other important organic compounds such as anserine and carnosine which also add to the antioxidant capacity of the body, prevent oxidative damage to cells, and support skeletal, muscular and cardiac health. PERQUE L-Histidine Guard supports cellular metabolism throughout the body.*

PERQUE Founder, Dr. Russell Jaffe, says, “PERQUE L-Histidine Guard is an important addition to the PERQUE family of products. Combined with PERQUE DigestivAide™ herbal bitters just before a meal, PERQUE L-Histidine Guard can help ensure a solid start to healthy digestion. Complete the digestive health quintet by adding prebiotic, probiotic and symbiotic products PERQUE Regularity Guard™, PERQUE Digesta Guard Forté 10™, and PERQUE Endura/PAK Guard™.” 

Other health benefits of L-histidine supplementation include:
• Cell and tissue growth, repair, and protection.
• Protection of nerve cells and support of memory and cognitive function.
• Healthy red blood cell production.
• Assisting in heavy metal chelation.
• Protection of hair and skin.

PERQUE L-Histidine Guard™ is  available to licensed healthcare practitioners at a low introductory price through PERQUE Customer Support (800-525-7372) or through your Clinical Account Specialist.
