Product Description

NOW Foods Black Walnut Hulls are a classic herbal aid for digestive support, delivering antimicrobial and astringent properties to help balance gut comfort. From NOW Foods, a family owned company since 1968, it’s produced in GMP facilities to ensure safety and purity. Dr. Duke of Duke University notes juglone and tannins in black walnut hulls may contribute antimicrobial and astringent effects in lab environments.

Available Sizes & Variants:

100 capsules - Standard daily pack for ongoing gut support.

Benefits & Features:

  • Supports traditional digestive balance in a convenient capsule.
  • Clear, vegetarian capsule fits easily into daily routines for steady support.
  • Key components like juglone, tannins and polyphenols are thought to contribute antimicrobial and astringent effects, helping explain why black walnut hulls have long been valued for gut support.
  • Quality focus: produced in GMP facilities with vegetarian capsules and non-GMO ingredients.
  • Clinical evidence in humans is limited, so this product is best used as part of a traditional herbal approach rather than as a proven treatment.

NOW Foods has a long heritage of transparent, quality minded production. This hulls capsule is a single-ingredient herbal supplement derived from Juglans nigra and produced in GMP facilities. The company has been family owned since 1968, with vegetarian capsules and non-GMO status reflecting a steady commitment to purity. For those building a gut health routine, this traditional option pairs well with probiotics, and it is not a berberine or vitamin d supplement.
