Natural progesterone supplement sources

Here are the low-excipient natural progesterone supplements that I am aware of. Please leave a comment if you know of other sources, have feedback about any of the suppliers, or just have suggestions on improving the page.

From what I've observed, Progest-E seems like the most popular product, and Ona's Natural comes out the most affordable. I haven't heard of a lot of people using Ona's though, so I'd be particularly curious to from people that have used it.

Ingredients

Yam-derived USP progesterone, coconut oil.

There is a theory that Dr. Peter Eckhart of Women's Therapeutic Institute (makers of Progestelle) is actually some kind of marketing pseudonym. I have no idea if that's true, but I choose to imagine that this is his work uniform:

Update: see the comment below for more information on Dr. Eckhart's credentials / identity.

Testing progesterone levels

I haven't heard one way or another whether it's useful to track your progesterone with bloodwork, but I've compiled a list of progesterone blood test providers if you're curious to know your levels. It runs in the $50-$200 range depending on which company you order the test from.
