Grab a measuring teaspoon
by: Shari

The printed information that came with your progesterone cream should give you the strength. It's usually 20mg per 1/4 teaspoon. Just multiply 1/4 X 5 to get your amount (1-1/4 tsp should equal the 100mg). Good luck and hope you get great results with your treatment.

How to measure progesterone cream
by: Dan

Hi, I received this answer from Wray who writes this column. As long as you are using a 1.6% progesterone cream. This is a 1.6% cream, which means it contains 16mg progesterone per gram or ml of cream. 1ml is 5th of a tsp, which means 1tsp of the cream you have contains 80mg of progesterone. So 1/8th tsp contains 10mg of progesterone, 1/4tsp contains 20mg progesterone.

Natpro in MG
by: CamperKat

1/4 U.S. measuring teaspoon (like you use for cooking/baking) of Natpro is 41 mg (milligrams), therefore 1/2 teaspoon would be 82 mg, and so on. Other creams (Dr. Lee, Emerita, Source Naturals) have different levels of progesterone, and it is 1/2 that of Natpro...meaning 1/4 teaspoon of the others gives 20 mg, etc.

Hope this helps.

By the way, this question is answered many, many times within this website.

Good luck to you.

Thanks for the answers. For those of you living in Canada, the following is the simple answer:

33.2mg = 1ml
1 tsp = 5 ml
1 tsp = 166 mg

by: Wray

Hi Christina I see you've had much help from many people! I see you must be using Natpro, as you give the correct measurements for it. But as Dan and CamperKat say, it varies considerably with the strength of the cream. We do have a list of comparisons at the bottom of our page How to use progesterone cream. 1ml of Natpro contains 33.3mg progesterone, making it a 3.33% cream. Take care Wray

Natpro is different than other brands
by: CamperKat

FYI, once again--after reading these posts, I am concerned that people are mentioning numbers without specifying what brand they are talking about...Natpro has twice the amount of progesterone than other brands like Dr. Lee, Emerita's Progest or Source Naturals. Natpro has 41 mg per 1/4 U.S. measuring teaspoon, and the others have 20 mg.

Hi CamperKat Thanks for pointing this out! I spend my life trying to guess what strength of cream people are using, or asking them to tell me. Many assume I must 'know' or can't work it out themselves, so a name does help immensely, I can then look it up on the web. I now have a long list of creams with the various strengths and ingredients which saves a web search! Take care Wray
