<<Disclaimer: Verify this information before applying it to your situation.>> I asked the list about probiotics. I'd say from the returns that Natren is the winner of the popular vote. I've included all the replies, whether they had good or bad results. Each paragraph below is a separate quote. -vance I use Natren's Trenev Trio which is dairy-free. It is a live capsule that Natren sends 2nd Day Mail in a styrofoam container with ice packs. It is around $119 for a 3-month supply. The website is www.natren.com. I used to take Priobiotic 8 until Dr. Fine suggested Culturelle to my son. Culturelle costs about $20 for a 30 day supply at CVS. Priobiotic 8 you can buy discounted in any HFS. I got mine at the Vitamin Shoppe, 30% off. Rosalie PS. I'm not sure it really helps or works?? I use a probiotics called perqdophulus - best on the market in my opinion and the best for the price. I order from a place called Thinking of You (they carry a whole line of everything-free vitamins) - the woman who owns this business is the brother of serraimmune labs where I had my food allergy tests done - they definitely work - if I take them daily I have no colds/sinus infections. Call 1 800-806 8671. They are in WA I was told about Probiotics by a Dr. and tried them. I found them to be essentially no help for me. So I went to enzymes. I tried everything. Nothing really helped. I even have a bunch of unopened bottles of Dygest and Prepzymes you could have. But the best combination I have found for me is Super enzymes from Twinlab and EnzmAid from Kirkman. www.kirkmanlabs.com and superE from www.needs.com . I take one of each with every meal. These are really good for me. They eat gluten before it upsets ones stomach. I don't know a lot about probiotics, but what I've been using is Jarro-Dophilus + FOS. I found it at My Organic Market (refrigerated)for about $10 for 100 capsules. It has 3.36 billion organisms, 210 mg. FOS, 1mg. Vit. C. It is dairy free. I used the dairy free powder by Natren. It is somewhat expensive, here it's $25 bucks a bottle, and I was told by my Nutritionist to buy the powder form (dont' have to worry about gluten in the capsules then) and you take a teaspoon of the Acidophilus, and the Bifidus before meals. There's always discussion about when to take them, but there are those two kinds or you can buy the 'Trinity' mix which you can just buy that one bottle and try then. I get several brands.....GET THE BRAND THAT MUST BE REFRIGERATED...keeps the little buggers active.... Solgar Multi-dophilus with FOS is GF, dairy-, corn-, and soy-free as well -- I talked to the company and then rushed out and bought a bottle. Unfortunately, it seems to **cause** diarrhea in my case. I am feeling unlucky these days... A naturopath told me to take between 5 and 30 billion twice a day, and many only are 1 billion. The one I found (does not have to be refridgerated either) is "Pro-Biotics Acidophilus" The company is Nutrition Now, Inc. Vancouver, Wa. www.nutritionnow.com. I found it the cheapest yet at GNC (General Nutrition Centers). I have taken Natren's Healthy Trinity (Dairy Free and Gluten Free) for some time. It comes in powder form or capsule. Their toll-free number is (800) 992-3323. If you become a "Health Club Member", you save 30%. Ask for Connie Dupre, Consumer Direct Supervisor, at Ext. 132. Ninety caps cost me $100.80 plus shipping but they're fresher than purchasing at the health food store, I have found.
