Nutricost Cat's Claw 1000mg (4:1 Extract)

A 4:1 concentrated extract delivering 500 mg of extract per capsule (equivalent to 2,000 mg of raw bark). Third-party tested at an NSF-certified GMP facility.

Why It Stands Out

The 4:1 extract concentration means each capsule is significantly more potent than whole-herb products. This exceeds the protocol's 500 mg whole-herb specification. May be preferable for those wanting a stronger dose, but makes direct comparison to 500 mg whole-herb difficult.
