Not sure what this product was supposed to use. Not using every day as it seems to cause lightheadedness?? Maybe an energy spurt?

At this point I’ve seen no difference and do not think continuing on this product is going to make any difference. I’m glad to try most things but this one did not seem to do any good thank you
