Purchase options and add-ons

  • ENHANCES MUSCLE TISSUE REPAIR: Natural Factors Micronized L-Glutamine is an athletic support supplement used to restore the body’s glutamine levels after intense workouts and physical stress. Supplementation with L-glutamine enhances muscle tissue repair after heavy physical exertion, helping to accelerate post-exercise recovery and improve energy levels.
  • MICRONIZATION TECHNOLOGY: Micronized L-Glutamine is a pharmaceutical-grade, free-form amino acid made through a natural fermentation process. It uses micronization technology to minimize the particle size, making glutamine easier for the body to break down and absorb.
  • SUPPORTS IMMUNE SYSTEM & DIGESTIVE HEALTH: L-glutamine also supports immunity and digestive system health, and has been shown to strengthen the intestinal barrier to protect it against exercise-induced intestinal permeability.
  • THIRD PARTY TESTING - ISURA VERIFIED CLEAN: The ISURA seal is your assurance that this product is independently verified as clean and safe, and has been tested for up to 800 possible contaminants. This product is ISURA verified clean, one of the highest testing standards in the world.

Good for the gut
I ordered this L glutamine capsules from Natural Factors to help improve gut health. I always take glutamine but in powder form. These capsules make it very easy and also give me a portable option. The pills are average sized and easy to swallow with food or water. There's no taste, smell or after taste. No side effects either. It comes in a bottle with an easy flip up lid for fast access. Theres 60 capsules and its recommended to take 1 capsule 5 times a day. There are many different protocols for how much glutamine to take so this would not be the only possible dosage (DYOR - do your own research). I've taken many more without any issues, to help fix gut problems. Even on an empty stomach there are no side effects. I've taken a lot of supplements from natural factors brand and never had any issues. Each capsule contains 1g of glutamine so its very easy to dose properly and accurately with this product. I will likely consider buying this again.

    I was using the powder previously and I did find it more convenient as remembering to take up to 5 of these capsules a day is a lot but seems to work just as great . I specifically use for digestive and bloating issues and I have been regular since using and my gut seems to be on the med!

    I usually take glutamine powder in my morning smoothie. The trouble is that I have not had one in weeks. I am changing up my diet and routine and I just haven't been able to fit it into my day as I could before.

    This has been a nice easy option for me to add it back in without any difficulty. You don't get nearly the amount as you do with powder, but there is much more involved in loading capsules. i think it is a decent price for the amount you get considering the convenience.

    I have used many Natural Factors products over the years and i am always pleased with the quality. This is no exception. Very pleased with this order.

    L-glutamine is touted as having many health benefits which can easily be researched online. However, unfortunately in my case taking this supplement worsened an existing health condition that I have. Stopping the supplement thankfully helped, but needless to say since I had a bad reaction to this and from my own experience I can't recommend it. This may be different for you though, so I would advise others to ask your healthcare professional if this is the right supplement for you before starting this or any other new to you supplement.

    Capsule form factor makes this glutamine supplement portable and easy to take with you on the go. Natural factors is a reputable brand so I have no doubt of the quality of this product. I take glutamine mainly because I find it helps with my sensitive stomach but also because of the reported benefits to muscle recovery. I notice my stomach isn't nearly as sensitive and it helps with gas. Muscle recovery benefits are less noticeable to me. My container had an expiry date more than 3 years out which is great.

    鶹 Vine Customer Review of Free Product( What's this? )
    The supplements industry is fraught with cheap, unsubstantiated products. It makes it difficult to trust what you are actually buying. This one from Natural Factors is made in Canada went through the effort of getting ISURA certified which is a real confidence inducing certification. ( I had to look it up).
    The last thing you want is heavy metals contaminating your vitamins and supplements! In any case the only downside is if taking 5 capsules a day (which is the recommended dose) you will finish this bottle quickly and burn a hole in your wallet. One star deducted simply for the cost effectiveness challenges.
