Transformation Enzymes probiotic formulas cover a wide span of strain counts and potencies. At one end sits a one strain Lactobacillus plantarum formula suited to ages 4 and up; at the other, a ten strain blend reaches more than 40 billion CFU per capsule. Middle options include a six strain formula with inulin from Jerusalem artichoke plus lactoferrin, which is milk derived, and a delayed release capsule pairing four strains, among them Bacillus subtilis, with a blend of four bacteriophages. Most are taken once a day, upon rising or at bedtime, with plenty of water. Several of these products need refrigeration to retain activity, so check storage directions as soon as an order arrives.
