Progest E natural progesterone oil complex continues to be our number #1 best seller for over 28 years! So many great unsolicited reviews speak for themselves!

Our Progest E Oil is sent out directly from the manufacturer. So you can be assured you are always receiving the freshest product possible.

Directions for use will arrive with your order.

Please consult your doctor or health practitioner if you have further questions or need individualized guidance.

Progest E Oil is not affected by the heat during the shipping process. Progest E is very stable. Upon receipt, though it is not required, it is recommended to refrigerate the Progest E if the weather if very hot, or for long-term storage to preserve its shelf life of 2 years. It is important to store Progest E out of direct light, which prevents product degradation. 

The resin used to make the bottle does not contain—BPAs, phthalates—or any other toxic chemicals listed for example under Proposition 65 in California or any other international toxics regulatory body. 

Additional Information:

  • In this 10% solution of Progest-E Oil Complex, one drop contains about 6 milligrams of natural progesterone.
  • The size of the drops will vary depending on several factors for example, the amount of pressure applied squeezing the bottle, and the temperature of the solution. 
  • A 60 mg drop contains 6 milligrams of progesterone and is a common minimum amount to use. An unpopped kernel of popcorn looks the same size as a 60 mg drop of Progest-E and can be used as a reference. There are approximately 560 drops weighing 60 mg in each 34 ml bottle. It is not necessary to be exact using this product. Use as needed.
  • Specific usage instructions will be emailed to you once you have placed your order.
  • See all products sold by Long Natural Health specifically geared towards women's health 

Dispensing and Storage Tips:

Prolonged exposure to high temperatures and natural light is known to reduce the shelf life of natural vitamin E.  To get the greatest benefit from the natural vitamin E in Progest-E, keep the product refrigerated (does not have to be), or in a cool dark place.

If you do refrigerate, and the bottle is too cold, the drops won't be easy to measure, so estimate (it is unnecessary to be exact, use as needed), or let it warm up outside the refrigerator for 20-30 min or so. It is only necessary to refrigerate in hot or long term storage conditions. Get an idea of your desired amount when the liquid is at room temperature. Then when it is cold estimate that similar amount. 

Storing the bottle upside down also ensures that the solution is always in the dropper tip ready for use. Note: Do not store upside down when the bottle is full because the liquid will dispense too quickly. Store right side up until it becomes difficult to squeeze out liquid from the bottle.

What about the Soy in Progest E?

The vitamin E in the Progest-E Oil Complex is derived from NON-GMO soy. The vitamin E used in Progest-E is of the highest quality and purification level and it does not contain soybean oil or soy proteins, those with allergies should have no problem with this product as any undesirable substance found in soybeans are eliminated during the extraction of vitamin E.

    Progest-E

    Posted by Julie B on Feb 16th 2026

    I began taking Progest-E it after I hit menopause in August 2025. It was important to me to find a product that was not a SCAM like most of the progesterone products on the market are. The health professional, who recommended it, told me this was the only product he would ever recommend to his clients. I’m so grateful he did! (Thanks, Zach!) And I feel the price point is excellent too. (Thanks Long Natural Health!) The recommendation was to take it 3 weeks on and 1 week off. The first 3 weeks I felt good, but I didn’t realize HOW good until I stopped taking it the 4th week. I didn’t like not being off of it at all! So, I did not wait a full week before starting it again. (I think I may have waited five days.) After that, I took it a couple of months straight. But I know that my body needs a break from it every now and then so that it doesn’t build up resistance. Now, each week I take it 5 days on and 2 days off. That seems to be working for me at this point. I LOVE this product and recommend it! ~Julie

    This oil works really well to balance post-menopause hormones. The oil sticks to the skin and does not rub off on clothes.

    Posted by Jocelyn M on Dec 29th 2025

    Messy and not convenient to use or dose. I have no idea if it even does anything but it doesn't seem to do any harm. LNH: Please be patient and give it some time. It does wonders for so many people. :)
