Great job from Purextracts team to put an end to preconceived ideas about polyphenols and OPC.
Four myths regarding polyphenols and OPC proven to be false.
1. All pine species are NOT the same.
2. Crude extracts or purified extracts may have the same amount of polyphenols, it does NOT mean they're equivalent.
3. A crude extract is NOT closer to nature than a purified one.
4. A purified extract is NOT much more expensive than a crude extract
