Cat’s claw, Uncaria tomentosa, is an herbal
extract. It has been used traditionally in Peru for over 2,000 years. Alkaloids,
phenols, sterols and glycosides comprise some of the naturally occurring
constituents of this herb. Joint Health: In a 52-week, randomized
double blind trial, cat's claw extract promoted joint comfort in volunteers. A
4-week study also suggests that cat's claw has the ability to promote joint
comfort, in part by moderating prostaglandin metabolism. Other mechanisms of
action that may account for these effects include modulation of both oxidative
stress and cytokine production.* Cardiovascular Health: Cardiovascular
protective properties include support for healthy vascular and platelet
function.* Immune Support: Cat’s claw alkaloids have
been specifically associated with enhancing immune system cell function,
including phagocytosis and macrophage activity.* Gastrointestinal Health: Studies involving
cultured gastric epithelial cells suggest that cat's claw may provide important
antioxidant protection for gut health.* This extract is sourced from the inner vine bark
of Cat’s claw (Uncaria tomentosa). It is standardized to contain 3% oxindole
alkaloids (2.73% POAs and 0.27% TOAs) and 15% polyphenols. Vitamin C (ascorbyl
palmitate) is derived from corn dextrose fermentation. Pure Encapsulations recommends 1-6 capsules per
day, in divided doses, with meals. Mild gastrointestinal discomfort has been reported
in some cases. Not to be taken by pregnant or lactating women. Cat’s claw may be contraindicated for individuals
who are taking blood thinning or antihypertensive medications due to a potential
synergistic effect. Mur E, Hartig F, Eibl G, Schirmer M. Randomized double blind
