Hello,
I'm curious which form of the above OPCs is considered the best? Is there a difference regarding pine bark and grape seed as to health benefits? Do the same studies pertain to both substances?
The main difference is of course, price. Grape seed extracts are super cheap in comparison.
And are there any recommended brands of either? For grape extract, I'm currently using Doctor's Best French Grape Extract (Biovin), as it's inexpensive and contains the extract of the full grape. I've considered a pine bark extract too, but it's pricey and I'm not sure it has any benefit over what I am using now.
Thanks.
