Judging from that list you've been reading the body thread on BHM
Yes people say that those 3 things increase circulation, while researching GB to find a good dosage for NBE it became clear that most of the testing done on GB was for the purpose of finding treatments for Alzheimer patients. Most of those studies only used at most 360mg. However, Isabelle brought up an interesting point about the lack of information on exactly how GB impacts your brain and it's possible negative impact on the hypothalamus, the part of the brain that is responsible for several things - namely the secretion of hormones.
Cayenne supplements are also supposed to increase circulation. But I don't know too much about its effects just that eating Cayenne peppers can cause indigestion, so if you choose Cayenne make sure you get the supplement. As for L-Arginine, it increases blood flow because it is converted into nitric oxide which causes blood vessels to open wider for improved blood flow. L-arginine also stimulates the release of growth hormone, insulin, and other substances in the body. But Wahaika informed me that it can increase testosterone, not sure since I've never taken it. Mainly because I have allergies, one doctor even thought I might have developed asthma as a result. Point is L Arginine can worsen allergies.
According to Isabelle, cinnamon would be another option as it also increases blood circulation. I think I'll be trying it out soon.
