Please note: due to greatly increased raw material costs, Vitals is unfortunately forced to increase the price of Microbiol Trio Platinum from 69.95 to 79.95. The shelf life of this product on delivery is up to 15 months. This product combines the well-known strains Lactobacillus acidophilus, LA-5 and Bifidobacterium lactis, BB-12 and Lactobacillus rhamnosus, GG, by far the most well-known strain. This created a superior trio. Microbiol Trio Platinum contains 20 billion cfu (colony forming units, or the number of viable bacteria that are able to multiply and form a colony). Also available as Microbiol Trio Basic with 3 billion cfu.
