Hi there,
Glad to hear that you've found such a great company... i think most of the ingredients would be spectacular, but there are some herbs you may want to check on individually.
I take another product also formulated by Jameth Sheridan called Vitamineral Green, made by Health Force. If your not sure about Revitaphi, I think you'll also love Vitamineral, its really similar, but is definitely safe for use during pregnancy. I was concerned at one point about the parsley in it, as I read that can cause uterine contractions in high doses, but after more research and talking to the local rep of the company, he assured me that it contained a very small amount, and also shared the story that his wife had used it daily during her pregnancies, and had the most robust and healthy placentas her midwives had ever seen.
Best Wishes !
