Pine bark extract
Pine bark extract suppliers and sourcing guide
Pine bark extract is most often a water extract of the bark of French maritime pine (Pinus pinaster), grown in the Landes forest of southwest France. The bark is ground and extracted with water, then purified and dried to a reddish-brown powder rich in procyanidins, catechin, taxifolin and phenolic acids. Branded and generic grades exist, and extracts from other pine species are also sold.

Generic maritime pine extract
Pinus pinaster bark extract from other producers, sold on procyanidins or polyphenols by a stated method.
Other pine species
Bark extracts from Pinus radiata, Pinus massoniana and other species; buyers should specify species because profiles differ.

What to check on the COA
Compare each result with your own specification when the lot arrives.
- Identity and species (HPLC fingerprint)
- Profile of catechin, taxifolin and phenolic acids to confirm Pinus pinaster and detect other species or grape seed and peanut skin blending.
- Procyanidins assay
- Procyanidins by the method the spec names (UV or HPLC); results are not comparable across methods.
- Heavy metals
- Lead, arsenic, cadmium and mercury by ICP-MS.
- Microbiology
- Total plate count, yeast and mold, E. coli and Salmonella.
- Loss on drying and solubility
- Moisture and, for drink grades, solubility or clarity.

Lots and expiry dates
Species and assay method matter more than the headline percentage. Record species, origin, assay method and supplier lot, and keep branded lot numbers traceable if the label names a brand.
