Hi,
I am a wellness consultant here is San Antonio specializing in detoxification. I also work 3 to 4 days at Cost Plus Nutrition. By far the best probiotics by any standards and in my opinion and that of many alternative medicine practioners is Natren located in California. You can buy these products at health food stores, but you are able to get a better price by ordering direct at 1-800-992-3323. Ask for Dave Ausdale, and if his line is busy, leave word for him to return your call. I have been working with him for about 8 years and he is very knowledgeable about all of the products. Tell him I referred you to him. If the price is too steep, let me know and I can get a better price for you by ordering it on my account. Contact me at ____@____.com if you have any further questions. Natren has the largest scientific research regarding probiotics at the Library of Congress. ( I believe that is where all the references are located.) As far as side effects, probiotics don't make you ill. If one has an overgrowth of Candida yeast in the body, one will usually have what's known as the Herxheimer reaction. By that I mean that as the yeast die off and release their toxins to be eliminated through the colon, signs of this dieoff can be some localized pain in the lower right quadrant of the abdomen near the appendix, diarrhea, flu like symptoms, headaches, sore throat, skin rash, etc. This is the body's way of eliminating toxins beyond the bowel. If the reaction is too uncomfortable, stop the probiotics for a day or so, and then start up slowly again. Be sure to drink plenty of good, clean water, like reverse osmosis water. Be sure to take a good whole food vitamin/mineral supplement as reverse osmosis water is devoid of minerals and because our foods have very little nutrition in them these days due to depleted soils. Organic is always better, but there is still the need to supplement.By the way, drink water between meals instead of with your meals. If you do drink with meals, limit it to water, and a small amount at that because drinking fluids with meals dilutes the gastric juices needed for digestion, and can lead to acid reflux. Also, never drink cold beverages at any time, as this shocks the stomach and intestines. If you have any questions you may e-mail me at ____@____.com.
