The simple fact is that living in today’s stressful world takes its toll on everyone’s health. To combat the ravages of modern life‚ help is available in the form of Perque’s Endura/PAK Guard. This powerful and effective supplement features a non-stimulant‚ energy-boosting formula that delivers relief to those suffering from chronic fatigue or mental “fuzziness”‚ while adding beneficial support for the repair of the intestinal walls.

Endura/PAK Guard can assist if you have:

  • Constant fatigue
  • The need to increase endurance
  • Difficulties with concentration and maintaining mental sharpness
  • A desire for quick recovery following exercise

The symptoms of chronic fatigue are quite often cured—or at least substantially reduced—by targeting the causes‚ which often include a diet deficient in necessary nutrients‚ a sedentary lifestyle that includes little or no physical exercise‚ and irregular or insufficient amounts of sleep. Research has shown that effective nutritional supplementation with essential vitamins and minerals can play a critical role in remedying deficiencies‚ promoting the elimination of toxins‚ and establishing an overall sense of wellbeing.

Endura/PAK Guard by Perque offers invaluable nutritional support for muscular stamina‚ as well as mental clarity. The exclusive formula boasts a unique combination of the valuable amino acids L-glutamine and pyridoxal alpha-ketoglutarate (PAK); glutamine serves as the principal fuel for your intestines‚ brain‚ muscles‚ and liver.

This supplement is an exceptional option for those with intestinal irritations. Its ingredients assist in the regeneration of the intestines’ surface cells; this is particularly important due to the fact that intestinal surfaces are quite vulnerable to abrasion and erosion caused by mechanical action‚ toxins‚ or atypical bacteria‚ and symptoms such as diarrhea or chronic constipation may result.

For over two decades‚ Perque has been formulating and manufacturing safe‚ effective‚ and unique dietary supplements. Perque products are often included in prestigious clinical studies‚ and have been shown to have more bioavailability than competing products. Founder Dr. Russell M. Jaffe’s goal has always been to integrate conventional medicine with a prevention-first mentality.

      I am a Chiropractor and have a sister with Crohns Endura/PAK Guard is part of a list of vitamins I give her and has really helped " cool" her colon...she tells me without Endura/PAK Guard she does not get the cooling effect..overall with the products I have her on and this one has helped reduce symptom flare ups...its pricy compared to other l~glutamine ...but I think this one is higher quality and does the job

      An important vitamin for my health

      from PA on 3/28/2011
      Almost all of the vitamins that I take are integral to creating and maintaining the Methylation Cycle. Endura/PAK Guard by Perque is important to regulating my blood sugar. Over the last year my blood sugar has become more stable with the use of this and other supplements and eating a low glycemic index diet.

      Endura/PAK Guard

      from Green Bay, WI on 3/17/2011
      Endura/PAK Guard by Perque is a MUST HAVE if you are diagnosed with Ulcerative Colitis. I have had three separate doctors recommend Endura/PAK Guard along with other PERQUE products to my diet. Endura/PAK Guard not only is beneficial to managing Ulcerative Colitis but in helping during times of flare-ups. I have a friend with similar problems as I have with my Ulcerative Colitis and since he has been on the PERQUE supplements he has had no problems and reportedly feels great! It is true that you only get out of your body as much as you put into it. PERQUE has helped with maintaining my overall good health and managing my Ulcerative Colitis.


      With PERQUE you are guaranteed to be getting the purist of ingredients without the worries of the possibility of unwanted cross contamination that other products can not guarantee. PERQUE stands behind their products which are backed by clinical research.


      This as well as other PERQUE products are not cheap especially when you compare it to other like products out there but whats inside the bottle is what counts!

    • Helpful and very mild

      from Indiana on 1/24/2011
      I was told by my pharmacy tech that Endura/Pak Guard by Perque would help with recovery from hard workouts and any digestion problems would improve. She was completely right. The lactic acid cramping post workout was diminished. I had few digestion issues but I will say that it seems like other vitamins are more effective since starting Endura/Pak Guard. And a big plus that was not mentioned was that I fall asleep easier at night. I have always struggled to get to sleep and this has a very mild relaxing effect. That is also whats great about these is the fact that all effects are subtle not harsh or bad side effects at all in my experience. Thats why I'm checking out more from Perque. Seems like an outstanding company!


      Relieved post-workout muscle cramping. Aids digestion. Aids ability to fall asleep.

  • Question:
    Hello, Is it ok to take Endura Pak/Guard with Repair Guard? Thank you, Nancy
    Nancy on 11/30/2017 Answer:
    • we apologize but here at PureFormulas, we cannot tell whether it will be okay to take those two products because there is so much to take into consideration when doing so. Everyone breaks down, absorbs, and reacts to nutrients differently, and only your healthcare practitioner, that is familiar with your needs, would be able to make a recommendation that is the best for you.
