If looking for alternatives to brands like Symprove, you should compare the cost, the recommended daily amount, and the quality of the strains. A high-quality supplement always lists the full strain names of the bacteria, not just the species, so you can check the supporting research. Optibac Every Day is a great alternative to Symprove and other similar brands; it out-performs most comparable products not only on price, but also on quality of the strains it contains.
