I think Pycnogenol can be from grape seed extract or pine bark--

ah, here's an explanation -
[Grapeseed contains flavonoids called oligomeric procyanidins (OPCs), which provide the body with 50 times more antioxidant protection than either vitamin C or vitamin E, and helps prevent and correct damage to capillaries throughout the body.

Scientists first studied the medicinal benefits of OPCs discovered in pine bark, which they referred to as pycnogenol.

The OPCs in grapeseed are sometimes still referred to as pycnogenol, but this is incorrect since the word pycnogenol refers exclusively OPCs in pine bark—OPCs in grapeseed have a different chemical and pharmacological action in the body. ]

So technically they both have the OPCs ..and sometimes both are called pycnogenol.

Take with meals
 

This is important..

The recommended adult daily dosage is 50 to 100mg, although up to 200mg (in divided doses) is a safe and effective dose. GSE should be taken with meals.
