For several weeks I take a daily capsule with grape seed extract. Most I am pleased that I have since then no more circulation problems. Before I got one to two times per week dizziness with headache and nausea. This was very unpleasant. Since taking the capsules, I have in this respect no more complaints. Also, I think, to have more energy in general. Anyway, I will not soon tired as before. I'm going to buy the capsules again.
