No other Cat's claw-even those with more mg. of extract or oxindole alkaloids OAs per capsule-provides Saventaro's unique benefits. Why- Saventaro is patented, clinically studied, and guaranteed to benefit both the natural and acquired immune systems. It's the first and only Cat's Claw product made from the root of the Uncaria tomentosa plant, where beneficial POAs pentacyclic oxindole alkaloids are 200% more concentrated than in the bark.Saventaro is standardized for a minimum of 1.3% POAs.- It's the first and only product guaranteed 100% free of TOAs tetracyclic oxindole alkaloids. Contamination by as little as 1% TOAs cause a 30% reduction in the acquired immune benefits that POAs provide.
