See our full sample process →White Oak Bark 5:1 Powdered Extract is a concentrated, five-to-one powder drawn from the bark of Quercus alba and carried on di-calcium phosphate, a free-flowing mineral carrier. It is supplied full-spectrum and, beyond the stated 5:1 concentration, non-standardized, a dry, blendable base for supplement developers working in compact solid-dose formats.
White oak bark is a traditional astringent botanical that continues to appear in digestive- and structural-wellness formulas as brands revisit heritage North American ingredients. A concentrated 5:1 powder gives formulators an efficient, dry way to bring that demand into capsules and tablets, and its long-standing place in classic herbal practice lends a product an authentic, time-tested backdrop.
The powder disperses into capsules, tablets, and dry blends, and rehydrates for stick-packs and mixes, with its concentration suiting compact dosing and multi-herb formulas. White oak bark is traditionally associated with digestive, bone and joint, respiratory, and weight-management support, structure/function positioning only, not a consumer health claim.
