Zetpil™ Branched Chain Amino Acid Suppository


Branched Chain Amino Acids can:

  • Increase muscle performance and recovery
  • Increase protein and muscle synthesis
  • Provide essential amino acids directly to muscles



The Zetpil™ Branched Chain Amino Acid contains the essential amino acids leucine, isoleucine and valine, which must be consumed through diet since the human body cannot make them from other compounds. Branched Chain Amino Acids (BCAAs hereafter) make up 35% of the amino acids in muscle proteins and 40% of the essential amino acids required by humans. Research has shown BCAAs to be beneficial for promoting healthy muscle mass, improving overall exercise performance, decreasing fatigue post-training, providing essential nutritional support, and may be important in preventing cancer-induced cachexia.

Zetpil™ Suppository Advantage

Zetpil™ delivers nutrition via the rectum with the use of suppositories that have a unique, all- natural formulated base that has revolutionized not only this mode of delivery, but also the ability to obtain nutrients in a far more efficacious method.  These suppositories are a result of combining natural ingredients with a non-irritating, rapid melting (5-6 minutes), readily absorbable (superior retention), antioxidant base material (free radical scavenging ability) and delivers the nutrients directly into the bloodstream in less than 20 minutes in a highly effective manner. Oral supplements are exposed to the hazards of stomach acid, digestive enzymes, food-related breakdown, first pass metabolism, and other bioavailability issues in the gastro-intestinal system.

Additionally, many raw materials simply have a very low bioavailability, and only achieve around 10% or less (commonly <1%) absorption rates, even if the patient is in optimal health condition. Compromised health, age, or certain conditions that result in an inability to take oral nutrients often preclude these patient populations from obtaining the necessary nutrition to stay healthy which often exacerbates chronic health issues. 

Zetpil™ suppositories are a NOW solution to delivering the necessary nutrients to patients, on a daily basis, that is both easy, comfortable and cost effective. The safety and noticeable effectiveness of these products will far outweigh any initial hesitation you have regarding this mode of delivery.

What Is The Source?

The Branched Chain Amino Acid is ideal for those individuals who wish to maintain a meat- free, vegetarian diet. Isoleucine and valine are produced from corn dextrose fermentation. Leucine is extracted from a variety of protein sources (primarily soybeans) and undergoes extensive processing and purification before achieving its final bioavailable form.

Research-Proven Uses for Branched Chain Amino Acids

Exercise and Training-Related Benefits

The International Society of Sports Nutrition (ISSNhas concluded that consuming BCAAs (in addition to carbohydrates) before, during, and following an exercise bout would be recommended safe and effective”, in part for the reasons described below.  http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2853497/

Branched Chain Amino Acids may play a role in athletic support by:

  • promoting muscle nitrogen,
  • enhancing alanine and glutamine production,
  • decreasing lactate production,
  • moderating central nervous system fatigue thereby supporting mental performance, and 
  • boosting energy while decreasing protein breakdown= increased muscle work capacity and recovery.

“Branched Chain Amino Acids (BCAA) conserve muscle mass and indeed, studies examining recovery from heavy endurance activity have shown evidence that BCAA are beneficial in reducing muscle damage (ie: soreness) and accelerating the recovery process.”  Prior experiments “showed that amino acid supplementation was effective in reducing muscle damage and soreness when consumed immediately before and during the four recovery days that followed a damaging bout of exercise.” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3395580/

“Branched-chain amino acids (valine, leucine, and isoleucine; BCAAs) help to inhibit protein breakdown and enhance protein synthesis. BCAAs have been reported in many studies to attenuate delayed onset muscle soreness (DOMS) and muscle damage induced by exercise.” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3827986/

“It is clear that exercise promotes degradation of BCAAs and yet muscle-protein synthesis is enhanced after exercise. Therefore BCAA supplementation before and after exercise has beneficial effects for decreasing exercise-induced muscle damage and promoting muscle-protein synthesis.”


Liver Cirrhosis

“Cirrhosis is a slowly progressing disease in which healthy liver tissue is replaced with scar tissue, eventually preventing the liver from functioning properly. The scar tissue blocks the flow of blood through the liver and slows the processing of nutrients, hormones, drugs, and naturally produced toxins. It also slows the production of proteins and other substances made by the liver.” http://www.webmd.com/digestive-disorders/cirrhosis-liver   

Therefore, diseases affecting the liver (ie: Hepatitic C, fatty liver, alcohol abuse) drastically affect a person’s nutrient status.  These nutrient deficiencies can cause muscle weakness, fatigue, fluid retention, jaundice and overall diminished quality of life (QOL).

Since “serum concentrations of BCAAs are decreased in patients with advanced liver diseases, several clinical trials have suggested that Branched Chain Amino Acid (BCAA) supplementation improves the prognosis of cirrhotic patients (by, but not limited to)”:

  • improving protein malnutrition and nutritional status in patients;
  • reducing the frequency of albumin infusion in children with end-stage liver disease;
  • reducing oxidative stress by reducing iron accumulation;
  • attenuating fibrosis; and
  • improving glucose metabolism.
