Lactobacillus acidophilus DDS-1: A Super Strain Probiotic?

Lactobacillus acidophilus DDS-1 (L. acidophilus DDS-1) is a strain discovered in the late 1950’s by Dr. Khem Shahani at the University of Nebraska. Dr. Shahani founded the probiotics manufacturing company Nebraska Cultures in 1981 and the DDS-1 (Department of Dairy Science strain #1) line is still sold by his company.

According to the Nebraska Cultures website, the DDS-1strain is currently distributed worldwide, but only Nebraska Cultures produces L. acidophilus strain DDS-1 with Dr. Shahani's manufacturing and stablizing techniques and quality-control standards.

However, Dr. S.K. Dash started UAS Labs back in 1979 and UAS Laboratories, Inc. (United Agricultural Service Laboratories) trademarked the strain, so now there are 2 producers of the L. acidophilus DDS-1 strain. Several manufacturers include the DDS-1 strain in their multiple-species probiotics products, including UAS and Nebraska Cultures. Apparently the strain is the same, but the way it is prepared for use is different.

Based on the ingredients, the main difference appears to be that the Shahani product has the supernatant in with the microbe, while the UAS has less ingredients which may make it more suitable for persons with dietary restrictions. Supernatant is the liquid fraction of the ferment that contains the metabolic products of the microbes that in themselves can have benefits.

I would not take DDS-1 as the only probiotic I ever take, however, because I firmly believe, and this belief is supported by research, that it takes a village of various beneficial microbes to keep us healthy.

It takes a village of microbes, not just Lactobacillus acidophilus DDS-1, to be healthy

So I would use DDS-1by itself as intensive support short-term, or use it as part of a probiotics-support plan, including:
