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.

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

    I’ve been on TRT for about 10 years. In the last few years I’ve had more and more difficulty with sleep. I ordered Progest E a few weeks ago and put a small amount under my tongue before bed. It worked the first night and every night since. I’m falling asleep and staying asleep and having vivid dreams. I also feel less wired during the day. Highly recommend this product and company.

    A friend recommended this product. I am 51 years old female in the midst of menopause. I am taking this as a supplement for hormones. I am very happy with how this has helped me regulate my hormones. It is a night and day difference for me. I feel calm and in control. My hormones are not out our whack like they were. I am happy with the taste and the ease of use of this product. I use as directed and massage into my gums. It has helped me so much. I highly recommend.

    Fantastic Product

    Posted by Maggie on Jul 25th 2025

    Purchased this 3 weeks ago for lowering estrogen, hormonal balance, & thyroid health. Trying the Peaty lifestyle. I feel more balanced and less reactive, but the changes feel subtle and gradual. I will stick with this and continue the Peaty lifestyle.

    Great Product & Customer Service

    Posted by Natalia on Jul 20th 2025

    I am a 8 days into using this oil for PMS symptoms and am already feeling so much calmer and level headed. It's a subtle but noticeable difference when I'm used to intense mood swings and body aches around this time. The team at Long Natural health are also amazing, my first order got lost in the mail and they sent a replacement right away. Super happy with this purchase and will definitely order again.
