"I went through a period of about a month where I felt unusually worried and uneasy. Nothing had changed in my waking life, so I just attributed the feelings to work and the news. It was only after discontinuing these probiotics that the feelings subsided. I hadn't connected the two. After a few weeks, I tried it again, and the vague feelings of uneasiness returned. So it seems very likely that this probiotic is the cause.

On the plus side, it did seem to help me to "go" better -- at least during the first few days. But it also seemed to interfere with my sleep. I wouldn't sleep as deeply as I normally do, and I tended to take up at 3 or 4, unable to go back to sleep.

I believe that Jarrow is a good brand, and that the probiotic is high-quality. I just don't feel like it agreed with me. I'm not a huge fan of taking single-strain probiotics as it is; I tend to prefer to take multi-strain brands or to get my probiotics from fermented foods. I only decided to try this particular strain because it was reported to help with bloating and constipation. I did notice improvement in that area, but not enough to justify the uncomfortable side effects."

"I don't think I'd be exaggerating to say this product has changed my life. I've experienced digestive discomfort in the form of irregularity, gas and bloating most of my life, but the fun really started when I hit my mid-40s. I've never been formally diagnosed, but my symptoms align with those of IBS with constipation. Not to sound over-dramatic, but the past 10 years have been increasingly miserable to the point that I have cut back almost completely on socializing and traveling due to digestive discomfort. (Dinner and a movie?--NO thank you! Road trip with friends? Forget it!!) A few years ago, I discovered wheat was a problem, and have eliminated that from my diet with much improvement (along with soy, wine, beer, added sugar, and most other "offensive" foods that could cause excess gas, bloating or intestinal pain) but still, was experiencing problems with digestion. I'm a 56 year old woman who lives a very healthy lifestyle--you'd think I'd feel better than this. At the suggestion of a friend, I started taking Jarrow 299v about 2 months ago, and I have noticed a significant change in regularity and in how my digestive system is working. I am no longer uncomfortable after meals, I don't feel abdominal pressure or pain after eating, and I am more regular. Could this be what normal people feel like? I have tried several other probiotics in the past but have honestly never had the results that I've experienced with Jarrow. I am only taking 1 capsule per day and doing just fine with that. I ordered the 3-pack, and the product was shipped quickly in a cool pack. I am storing it in the refrigerator till I use it. I recommend anyone with irregularity issues give Jarrow 299v a try."

"This probiotic changed my life-literally! I am a dietitian and diabetes educator, and with my science background I decided to research a new probiotic to see if I could reduce my IBS symptoms. There was an small but scientifically sound study regarding the organism used in this product called lactobacillus plantarum. It showed significant regression of IBS symptoms in a statistically significant percentage of participants. And it worked for me! After 1-1/2 months I am off of two of my IBS medications and cut in half a third medication dose. I don’t need the FODMAP diet to control my symptoms anymore, and most excitingly,I can tolerate gluten again! What a life changer! Obviously this won’t necessarily work for everyone but it is worth a try given the potential for improvement in daily symptoms and the Lip liberalization of your diet. I have sent it to my daughter who is struggling with her IBS and I hope she gets the same results as me."
