Bioidentical Progesterone Oil | USP Grade


Kossma's USP-grade Bio-identical Progesterone is sourced from wild yams that are converted into bio-identical progesterone. It is formulated with vitamin E and organic extra virgin olive oil to ensure maximum absorption.

Please note that we cannot legally advise on certain questions regarding how to use Progesterone like "can I use this while pregnant" or "can this replace my current medication" - please direct all health related questions to your medical provider. Thank you for understanding. Topical use only - do not ingest. 




Bio-identical progesterone, vitamin E, organic extra virgin olive oil.

Kossma's progesterone oil is formulated with careful consideration to enhance the potential benefits of progesterone, by including synergistic components such as vitamin E and olive oil. Here's a look at the science behind it: Vitamin E, being a fat-soluble vitamin, is known for its antioxidant properties and its ability to support estrogen detoxification. When combined with progesterone, which also aids in detoxifying excess estrogen, this formulation may contribute to a potential reduction in excess estrogen levels, potentially leading to a stabilization and increase in natural progesterone levels in the body. The addition of olive oil is intended to improve the skin's absorption of this topical formula.


Disclaimer: Bio-identical progesterone is not classified as a supplement by the FDA, and therefore, there is no standardized dosing. Please consult with a medical doctor for personalized guidance on dosing and usage. This information is not intended to substitute professional medical advice. Always seek the advice of your physician regarding any medical concerns or dosing questions.

For topical progesterone oil, the typical daily dosage ranges between 20-40 mg. We suggest starting with three drops, equivalent to 9 mg, and gradually increasing your dose up to 20-40 mg per day, maintaining this dosage throughout your regimen. Apply the progesterone oil topically to areas with thin skin, such as the inner wrists, inner arms, and inner thighs, rotating the application site for optimal absorption. Topical application only.

Each drop of Kossma's progesterone oil contains 3mg of bio-identical progesterone.

Cyclic Women:

For cyclic women (those who have a regular menstrual cycle), it's recommended to start bioidentical progesterone therapy in the second half of the menstrual cycle, after ovulation. This is often referred to as the luteal phase and usually begins around day 14 of a 28-day cycle. Women who have standard cycles, 27-30 days can start at day 14 (or after ovulation) and continue daily until your next menstrual cycle starts or 1-2 days before the new menstrual cycle starts. After the new cycle starts, stop the progesterone until the next luteal phase. Women with shorter periods, start at day 12 (or after ovulation) and stop when new menstrual cycle starts.

Natural progesterone levels rise after ovulation, so it's important to start progesterone after ovulation to follow the natural cycles of the body.

Non-Menstruating Women:

Unlike cyclic women, non-menstruating women don't have a menstrual cycle, so they may be prescribed a continuous dosage or a specific pattern that doesn't adhere to a menstrual cycle. Please see your health care provider for proper instructions based on your individual needs (breastfeeding women, pls follow instructions given by your healthcare provider)

Menopausal Women:

For menopausal women, hormone levels don't fluctuate in the same way as they do during the menstrual cycle. Therefore, progesterone might be taken continuously or in a cyclical manner, depending on your individual needs and what your health care provider recommends.

I noticed a difference in the first cycle I used this! Mood swings lessened.

Freya S
Helps with sleep and blemishes

I love this stuff! I’ve been in a period of high stress in my life and this has helped to keep my hormones more balanced and promote deep sleep! I also put it on blemishes if I’m the pop up to help the healing process along!

Good start

I've only used it once so far as instructed but did notice my cycle was not as heavy as normal and also fewer clots. My mood seemed more stable as well. I look forward to continue using to see what else balances out!

Great product

so far i like this oil, first month using and have noticed less breast tenderness and better mood

Candace Cooper
Quality, Value, Efficacy

While I’ve only been using this product cyclically for one cycle, I’ve noticed an immediate improvement and am optimistic this will help with my low progesterone due to PCOS. I’ve seen deeper sleep, more calm throughout the day, evident ovulation and a good luteal phase. I’m eager to see if it eases my PMS (moodiness, breast tenderness, cramps). I’ve also been using 2 drops on my face at night and my skin has more bounce and has cleared up a bit from its usual hormonal breakouts in my jawline. All in all, I’m really happy with the quality and value for the price.
