I've been using arginine 1000 for several years now. I have cirrhosis of the liver and my blood ammonia rises. My doctor had me on a medication that makes me shudder just to think about. My personal research revealed I should use arginine and I have been very pleased. Just over a month ago my wife bought a different brand and I began to experience extreme fatigue and was sleeping a lot. Deciding the arginine was not good I returned to the Jarrow brand again and increased my dose to 2 a day. Within a couple of days I began to feel better and have considerable more energy, which is sadly still low. Thank you for arginine 1000. 


I Just wanted to give you a HUGE thanks for your Jarro-Dophilus EPS product. I developed diverticulosis about two years ago when I turned 38. My Dad has the same disease, so it figured I would get it. I was having "episodes" about once every three months, where I would quickly and unexpectedly lose a fair amount of blood when I used the bathroom. It was always scary to see blood in the toilet, and to feel weak for weeks afterwards. I can't tell you how much it affected me psychologically either, knowing that this could happen anywhere, at any time. I started taking the EPS product daily nine months ago, and since then, not even a single occurrence! I haven't changed my diet or anything, so I'm assuming it's this product that's working. Thank you SO much. In a world where so many products over-advertise but under-deliver, this one actually appears to work! I told my doctor about it and he found it very interesting, and suggested that yes, it was probably the probiotic that was helping. Thanks a lot! It's really hard to convey in words how much this means to me.

I have been using your Resveratrol Synergy 200 mg since Aug of 2008. I have never had such a good result in my Blood Test reading in many , many years. Thank you for this great product. This was the only new supplement I added to my daily regiment, so I attribute it it to this. I chose your product from many others on the market because it was the purest.

Hello. Normally, I'm not one to write "testimonials" for products- and my experience may be a total flook, but I want to share it with you. Long story short, I went through chemo 2 1/2 years ago with stage 3 follicular lymphoma at 39 years of age. The chemo caused some side effects, which they had prepared me for- one of which would be "early menopause".  Fine. I couldn't have cared less, I just wanted to survive. After completing the chemotherapy, their predictions came to fruition. I didn't get a period for 19 months, and tests confirmed menopause. At that point, I started taking your resveratrol products with my other vitamins and supplements. GET THIS! My body resumed "normal levels" after 4 mos of including resveratrol daily!  Granted, I'm not trying to have more children, but I am THRILLED to not have menopause issues at 42! So, that's it, I just wanted to say, in addition to healthy skin,etc., I am back!! All thanks to resveratrol!

Hello, I am writing to tell you about the great, and somewhat accidental, success I recently had with your supplement Neuro Optimizer. Not too long ago I went to my local health food store Lassens in Ventura California where I often go when I'm looking for quality supplements and won't get the hassle or poor recommendations you get a large retail chain stores. I went looking for a brain supplement similar to one I had a specific success with (long story but I was looking for more detailed dreams) in the past that contained L-Tyrosine and DMAE. The store had a surprisingly large selection of brain supplements and after a few minutes went by I accepted help from a store associate who insisted on helping me. I didn't tell her much other than I was looking for a good brain supplement. Literally she didn't let me say anymore as she reached for your product and couldn't stop talking about her own success with it recently while she was in college. At first I was reluctant because it didn't have the ingredients I was looking for and it was a little higher in price than I was looking to spend. However since I had recently returned to school I decided to take her advice and try it. Needless to say I was amazed! I can't believe the clarity of thought this product gives me and has been a great help in some of my more difficult computer classes I've been taking. I also seem to handle stress a lot better while taking it. All of these benefits have been great during my time of unemployment as I try and both develop new skills and get back in the job market. Thank you so much for making this product. I have since been telling my family and friends about how great it is so please don't stop making it! :) Below is my address, if you have a mailing list please feel free to add me to it! When I went to your website to get this email address I also saw you're on facebook and I will be "liking" you as soon as I hit send on this :) Thanks again for a great product!

I just wanted to tell you how happy I am with the Ultra Bone Up. I broke my #4 metatarsal bone in a paddling accident and began taking the product immediately. I am 55 years old and didn't expect to heal as fast as I did. I was totally blown away to be completely off the crutches after 2 weeks and out of the boot-cast after 3 weeks, well ahead of the doctor's predicted time frame. Well worth the money and I would highly recommend the product for broken bones.


I wanted to send a special thank you so all of you at the Jarrow team for the amazing work that you're doing and the products that you provide.

I began my fitness journey back in December of 2012, and have been using your chocolate and vanilla Whey Protein and probiotic supplements as part of my daily nutrition plan. I just completed my first natural men's physique competition and ready to get back out there an continue to improve my body, fitness, and overall health with the use of Jarrow products.

With many thanks and gratitude,

-Mason Marangella
