works great when it works
i bought the 20 day parasite program (older version of the current 18 day program that was half off and still good till aug 2018). thankfully i decided to look more into the program while i waited for the vitamin c that the older program version only mentioned in manual itself. found out this ornithine was recommended with the current parasite program and thank goodness i bought some for i really needed it on fourth night of parasite program, the third night was a restless night galore without it! took 2 and i slept so soundly that i thought it was time to wake up at 3am in the morning. next night took 2 and it did not do much at all so took 4 like i was suppose to do the next night and slept good and followed direction after that somewhat (took 5 next night and 6 after that). seems to require more and more for it to work but, could be cause i am on the higher doses of the parasite program now i suppose but, am not waking up as refresh as i was the first couple uses so i take one arginine in AM now although that stuff doesn’t seem to do anything that i can tell.. Since i think the higher parasite program doses is why ornithine is working as well as early on, i am definitely going to still use this when i am finished with parasite program cause unlike the natural alteril sleeping aid i normally take when i can’t stay asleep, this ornithine made me feel like i got a good night sleep and i felt great the next day early on in the program.

HELPS ALOT WITH TRAPPED GAS AND ABDOMINAL PAIN
Great stuff to reduce ammonia in body and brain, but so far hasn’t helped with sleep. On the other hand, I have severe insomnia likely from Candida and co spewing off their toxins and poisons over and above what my body can handle. I suspect upping the dosage gradually and sticking with it for a few months will result in more improvement. L-Ornthine is an important part of protein synthesis, along with L-Arnithine and L-Lysine being the other top ones. Anyone suffering from digestive problems should try L-Ornithine, especially those with SIBO, SIFO(FOR SURE), IBS, IBD, Crohn’s etc. In the past, I had used L-Ornithine L-Aspartate and did not experience relief like I do with Dr. Clark’s product. I also currently use molybdenum(primarily for acetaldehyde die-off), chlorella, bentonite clay, activated charcoal, olive leaf, pao d’arco, monolaurin and others. Also important to replace some good bugs, so making my own yogurt in between, taking probiotics, but mostly trying to get it from food sources. In my health journey I am finding that “Let food be thy medicine” is true. Healing needs to take place on all levels of mind, body and spirit in order to get well. And the path can be a long one. Good luck, take your time and enjoy the unfolding of your life before your eyes.

Not sure yet if it’s right for my body at this time.
The product is perfectly fine.. just not sure if it’s right for me at this time. It may be at a later date.

I love Dr clark products and started buying them off of Amazon to save money on shipping. I use these occasionally for helping me sleep. They work for me.

Amazon always has what you’re looking for
Dr. Hulda Regehr Clark was a Natuopath, author, & practitioner of alternative medicines. She past in 2009, leaving her family to keep her artistry alive. She was the pioneer of making everything to cure ailments and her books are the full source of her wisdom and knowledge from ‘Cures for all Cancers,’ and ‘Cures For all Diseases’. Her family has been keeping her incredible legendary history alive to make sure all her products remain the same. I purchased her parasite clense from her, (as it is known that 9 out of 10 people have parasites living within them and are unaware). You can certainly find out by searching, what are the symptoms of having parasites? I purchased the Ornithine because her directions of taking the “Green Hull Black Walnut,” can lead you to have constipation. So better save than sorry. Now I can start my cleanse.My brother who is a homeopathathic therapist told me the Parasite clense should be done once a year. I’m so glad to have gotten Her Ornithine!

Love this simple amino acid
My doc recommended I take 1-8 at bedtime to help with brain fog and workout recovery. It helps with both! I take 3 at bedtime and wake feeling great and no brain fog. I was telling the doc how much I like it, and he mentioned, ” Are you sleeping better? The thing is, I already sleep great. this is now part of my daily routine.

Better sleep, best clean ingredients!
As a fitness, wellness, and nutritionist coach I always look for CLEAN, transparent ingredients, 3rd party tested, and NSF certified if possible. I ordered this creatine for myself and after a few weeks I started noticing the benefits. Skin improved, appetite control, muscle strength, and even memory and mental clarity. I got my dad and my mom a container and have been promoting this to all my clients. This is a wonderful company with clean ingredients and good quality supplements. I also added their D3 & K2 as well as Saffron supplements to my daily stack! Also started taking this and my sleep has improved ten times over. Supper happy & life long client! For the clean ingredients and peace of mind your getting this company is a great value for money. No taste or odor and has helped me replace my sleeping and anxiety meds! Thank you SR!
