Bio-Kult Advanced Multi-Strain Formulation
Bio-Kult is a highly respected brand that excels in evidence strength, as this specific 14-strain formulation has been used in successful clinical trials for IBS and migraines. It uses specific alpha-numeric strain codes (PXN designations) and guarantees CFU counts through the expiration date, which aligns with quality research. However, it sits in the Silver tier because the 2 billion CFU per capsule is lower than the 20 billion 'Gold Standard' spec, and it lacks both a delayed-release capsule and high-level third-party certifications like NSF or USP.
