good price & fast deliveryThis probiotic was recommended to me by a doctor years ago. My husband and I both take it daily so I like to keep stocked up here from Amazon where the price is very reasonable. If/when you begin taking this product it will take several days to really kick in but once it does you will notice a more calm and easy stomach and digestive system. I had frequent heartburn prior to taking align but this virtually eliminates any and all symptoms of heartburn. It's so much healthier than taking chemical type heartburn medications. It is also great to promote healthy intestines and fights the bad bacteria build up in all parts of the body. It even promotes fresher breath by fighting bacteria which may add to this problem. I never had this issue but for those that do you will enjoy this benefit. Probiotics require consistency and not giving up on them, howevever once you stick with it a while you will begin to notice many positive changes. They are also known to fight yeast infections and athletes foot. Gross problems yes, but who doesn't want natural remedy and especially prevention of such issues? I have tried other probiotics in the past but they don't compare with the quality and comfort of Align. Other probiotics can cause stomach upset in the beginning stages but I never experienced that with Align. I hope this review helps! :)This was very effective for me in the aftermath of an h. pylori infection treated w/triple therapy antibiotics. I never experienced any bowel problems (diarrhea, etc.) due to the antibiotics. It also seemed to promoted regularity and absence of IBS symptoms. However, after about three months of use, I developed significant nasal congestion at night. Only over time did I decide to drop the probiotic, after which nasal congestion seemed to subside. I tried Align again, and still I thought I noticed nasal congestion re-develop. Has anyone else noticed this? I thought this strain of probiotic was supposed to be "histamine degrading" or at least good for people with allergies. (I have also experimented with other forms of B. Longum or B. Infantis that are not cultured in dairy, but to the same effect: nasal congestion. Thus, I do not think milk allergy is the issue.)Align probiotics gave me my life back. I spent from 1999 to 2014 planning everyday around where the bathroom was. I had to give up so much of my life. Things as simple as hiking. And it wasn't just the proximity of bathrooms, it was the cold sweat, pass out pain that would go on for hours. Within 3 days of taking Align probiotics I was fixed. If I think I don't need it any more and stop taking it the issue comes back within a week. I'm an Align fan for life and so grateful. Hopefully this helps someone else in the dark.I have psoriasis for more than 10 years. I bought this product (and other probiotics) because I saw a paper that showed the bacteria in Align improves the skin, and also reduces inflammation markers (CRP, TNF alpha etc.). I have been taking this for 3 weeks (plus other higher dose probiotics and supplements) and my skin improved. It is less itchy and flakes less.I started taking daily 30 Billion CFU and 90 Billion CFU probiotics with Bifidium bacteria, and I noticed my skin inflammation is improving faster. Therefore other products with similar strain may also help psoriasis, and, more importantly, psoriasis may require a higher dose and longer time to work.I will keep on taking Align because it seems to work for me and is backed up by scientific studies.I’ve been taking Align for years after contracting C. Diff. Antibiotics can be lifesaving, but horrible side effects can occur. By taking a probiotic, I am assured that I will always have normal gut flora. I even feel better physically by taking these pills. I’m going to go out on a limb & say that the main ingredient in the Align probiotic has been the most widely studied probiotic. This was true at one time. So if you want the best (probiotic), you need to buy a box to test its effectiveness.TAKE ONE OF THESE EVERY DAYThis going to sound gross but...I had straight up “loose stools,” which I called diarrhea, for 8 months. I saw 3 gastroenterologist during that time. The last one seemed frustrated with me because the previous prescribed treatment hadn’t worked and he didn’t have any better ideas. I happened to have have a flu and went to see an urgent care Dr. Who recommended Align. It cured my diarrhea. A little expensive but well worth it!
