I have been using fine powder vitamin c for over avyear now. I did the pregnancy protocol with my now 10 week old baby. It was the best pregnancy I have had! (He's my 5th baby) no nausea, no fatigue until late in my 3rd trimester, he was born so pink and so big! I have continued with between 6 and 10 thousand mgs during post partum/breastfeeding and i have to say that i have had a dream post partum experience compared to my other babies. I cant say enough great stuff about Revitalize and their products! High quality I know I can trust!
