As for the efficacy of the supps in question, it is clear that you don't consider either of them worth the risk. Is that because you do not believe the risk warrants the reward or do simply believe that they just aren't that helpful anyway. While the vasodilators aren't something I have looked into as extensively as other more promising substances my findings so far suggest that Vinpo at least tends to be associated with some impressive benefits as well as the risks. From what I understand, in some cases it can actually reduce the risk of complications, particularly when excessive constrictions on blood flow are in place. This is where actually knowing what is going on in your head starts to matter!
Thanks for the links Zoroaster. They are something to consider when taking either ginko or vinpo. However, they are not what is needed to support the conclusion that you draw. You need to find studies that suggest that 1 unit of ginko plus 1 unit of vinpo is worse than 2 units of either. You are concluding that the combination is the problem, not that the respective dosages merely have additive effects. Do you see the difference?
"Do I see the difference?" That's a simple concept wedrifid. I'm not a child. I was NOT concluding specifically that the combination was worse then the two individually. Only that neither is worth the risk separately so taking both of them (in other words taking two supplements that each carry more risk then they're worth) is a bad idea. Do YOU see the difference? I don't believe I ever implied that they had some kind of compounding effect on eachother. I'm sorry if you got that impression. You may be confusing my statements with regimens.
I did, however, point out that the use of either of these supps is always advised against when the subject is already taking any other kind of blood thinner, even on websites dedicated to each supp. So since each of these supps is a vasodialator and a blood thinner, each is officially contraindicated when taking the other. Why is this? Because blood thinners can have nasty side effects and they do carry risks, as I pointed out before. And taking two different blood thinners will only increase these risks, not necessarily in a exponential way but linearly, simple because you're now taking more blood thinner. So its a bad idea to take the two together simply because they have similar effects and taking both of them will increase the risks associated with these effects. Just like how taking a full dose of both aspirin and advil at the same time is a bad idea. Or just like how taking a full dose of alpha-GPC and a full dose of choline bitrate increases your chances of getting negative hypercholinergic symptoms. There doesn't have to be a synergistic effect for it to be a stupid idea.
