Thorne Prebiotic + stands out for its use of PreticX (XOS), a clinically validated prebiotic that works at much lower doses than traditional fibers, significantly reducing the risk of gas and bloating. It also includes green tea and pomegranate extracts to support the growth of Akkermansia, a 'keystone' gut bacteria linked to metabolic health.

Ingredients & Purity

Contains Xylo-oligosaccharides (PreticX), pomegranate extract, and green tea phytosome. No gluten, dairy, or soy.

Scientific Evidence

XOS has been studied extensively for its ability to selectively increase Bifidobacterium without increasing gas-producing bacteria. Pomegranate polyphenols are clinically shown to support Akkermansia muciniphila.

Brand Transparency

Thorne is a leader in transparency, manufacturing in an NSF and TGA certified facility and performing four rounds of testing on every product.

Value Assessment

At $1.50 per serving, it is premium-priced, but the low-dose efficiency and additional polyphenol support justify the cost for those with sensitive stomachs.

Why Not Alternatives?

Unlike bulk fiber prebiotics (like Inulin) which often cause significant GI distress, Thorne uses XOS which is effective at just 1-2 grams. It also carries the NSF Certified for Sport designation, ensuring a level of purity and testing that most 'lifestyle' brands lack.
