What to Avoid
Amazon's marketplace model creates storage condition risks. Big box retailers often carry outdated stock. Here's what to watch for.

Amazon Basics Probiotic (Warning Example)
Drugstore probiotics often sit on shelves at room temperature for 6-12 months—killing most live cultures before you buy them. The strains used are typically generic, underdosed, and poorly researched. Expiration dates are frequently near-term. Unlike...
