FloraSport 20
Thorne's FloraSport 20 is specifically formulated for athletes and those with high-activity lifestyles. It is NSF Certified for Sport, which is a rare and vital certification for probiotics to ensure no banned substances or contaminants are present.
Quality & Materials
A unique blend of four strains: Lactobacillus paracasei, Lactobacillus acidophilus, Bifidobacterium lactis, and Bacillus coagulans. Designed to support both gut and immune health during intense training.
Evidence & Testing
The specific strains used are well-documented for reducing the duration of upper respiratory tract infections in athletes and supporting GI health during travel.
Brand Transparency
Thorne performs four rounds of testing on every product. While they don't share full COAs publicly for every batch, their reputation and NSF status provide high confidence.
Value Assessment
Priced reasonably for a professional-grade supplement, though the strain count is lower than other premium options.
Why Not Alternatives?
While it has fewer strains than Seed, its NSF Certified for Sport status makes it the only choice for competitive athletes. Thorne's manufacturing standards are generally higher than retail-focused brands like Align or Renew Life.
