I have been taking Advantage now for about three months. I do feel more energetic. I will continue to take this as recommended by Louise Guttenhal in her Radical Longevity book, she says it is the best of the resveratol supplements. And David Sinclair is very pro resveratol too. Should take it with fat of some kind as it’s not water soluable. So I take it with my bullitporrf coffee with Mct8 oil in it everyday.
