回复：活性乳酸菌英文怎么说，在美国有什么相关的产品？

I think you mean probiotic products. Sure you can find the best in U.S. You can take some flora. I recommend the best one: Total flora from Infinity2 (looking for the family size,250 tablets.). Also you can have some yogurt (plain, organic) after meals. Some people can not digest milk product well.And the high content of carb may cause acid flux.
