Has anyone tried pycnogenol or grape seed extract?

They are apparently very similar, but grape seed extract (note that it's grape seed extract, not grapefruit seed extract, which is totally different), is a lot cheaper, as a by-product of the wine industry etc.

I am currently trying pycnogenol, at a dosage of 30 mg, which is quite a low one.

I've just realised that I never updated this, and I should have.

Basically, I did find that pycnogenol helped my migraines a bit, as a preventative.

But it didn't really agree with me. It gave me a slight chest pain (muscular I think), which was a bit odd. Also my eyes would get a bit bloodshot. I couldn't find any of this online when scouring side effects etc.

So, I'd cautiously recommend giving it a go!

edit: I forgot to say, the weird thing about it is that it appears to increase nitric oxide levels, and therefore blood flow. However, everything I've ever read says nitric oxide = migraines. I really don't understand it, but I do wish I'd managed to get pycnogenol to work for me without side effects.

I did also try the grape seed extract, but I had the same slightly blood shot eyes with that too, so I worried it was too much of a blood thinner.
