This site states this directly across multiple sections: no caffeine or fat-burning stimulants, and a non-GMO formula, per sources reviewed.
The stimulant-free claim positions this formula as a gut-health complement rather than a quick-fix burner, distinct from the separate non-GMO claim about ingredient sourcing — worth reading these as two specific, separate points.
As with any brand-stated claim on this site, worth confirming both statements against your own bottle's supplement facts panel rather than relying on the homepage description alone.
