Has anyone experienced dizziness or low blood sugar with Grapeseed extract ? Apart from that, I take MSM once in a while, a b-complex with vit C, beta carotene, vit D and schizandra. Could any of these cause a low blood sugar or dizziness ? I get slightly dizzy right after eating, so I am thinking it might be related to blood sugar levels. My blood sugar levels are usually in the 70's whenever I have been tested.
