Natural Treatments for Thin Endometrial Lining

The uterus is made up of three layers: an outer protective layer, a muscular layer, and an inner lining (endometrium) which develops each month to support and nourish a fertilized egg. If a woman does not conceive, this lining is lost during the menstrual period.

Endometrial thickness is an important factor in improving pregnancy outcomes. An ideal thickness is between 9-10 mm at ovulation. If your endometrial lining is thin it may not allow for optimal implantation and successful pregnancy.

A thin endometrial lining can be identified on ultrasound done at or near ovulation, or can be suspected in women who have very light menstrual periods.

Women with long term use of birth control pills (10 years or longer) are more likely to experience thin endometrial lining. Use of the fertility drug Clomid (Clomiphene citrate) is also associated with thin endometrial lining, especially when used for multiple cycles in a row.

Below are some suggestions for ways to naturally increase the thickness of your endometrial lining and improve your chances for a healthy pregnancy.

Red Raspberry Leaf Tea

An herbal medicine with a very long history of use, red raspberry leaf (Rubus idaeus) is a uterine tonic that may help to optimize development of the uterine lining. It is also a rich source of nutrients to support a healthy endometrium, including iron and vitamin C. Drink three cups of the tea per day from the first day of your period until ovulation.

Black Cohosh

Another herbal medicine, black cohosh (Actaea racemosa) is a rich source of phytoestrogens that can provide further estrogen stimulation to the uterus and support a thick endometrial lining. Studies have been done combining black cohosh with clomid and found improved endometrial thickness and more successful pregnancy rates. Dosage ranges from 80-120mg per day from the first day of your period until cycle day 12. Best taken under the supervision of a naturopathic doctor who can monitor liver function for optimal safety.

Red Clover

Red clover (Trifolium pratense) is another isoflavone rich phytoestrogen, similar to black cohosh. It is used to increase blood flow to the uterus and support estrogen balance in the body. It is used daily from cycle day 1 to 12 at a dose of 40-80mg of standardized isoflavones.

Bioidentical Estrogen

If estrogen levels are low (which occurs as we get older) then the lining of the uterus will not develop optimally before ovulation. A blood or saliva test for estradiol can identify low estrogen levels and a bioidentical estrogen cream can be used safely to increase estrogen levels in the first half of the cycle, prior to ovulation. Your Naturopathic Doctor can prescribe bioidentical estrogen at a dose that is individualized to your needs.

Iron

Iron deficiency is the most common nutrient deficiency in women. Necessary for the health of red blood cells, low levels of iron may lead to an inadequate development of the uterine lining. If you are a vegan or vegetarian or have a history of having a thin uterine lining, ask your Naturopath or Medical Doctor to test your iron (ferritin) and hemoglobin levels.

Exercise

Inadequate blood flow to the uterus can be a significant cause of a thin uterine lining. This can be caused by a sedentary lifestyle, chronic stress or uterine fibroids. Exercise and acupuncture are two of the most effective ways of improving blood flow to the uterus. Swimming, walking, jogging, dancing, yoga or hula hooping are all excellent ways of getting the blood flowing to the uterus. Try engaging in some form of physical activity every day, especially in the two weeks leading up to ovulation.

Researchers have found that the use of these two nutrients can increase the blood flow to the uterus through the uterine radial artery. Published in the journal Fertility and Sterility in 2010, it was found that vitamin E increased blood flow in 72% of patients and increased the endometrial thickness in over half of patients. L-Arginine increased blood flow in 89% of patients and increased endometrial thickness in two-thirds of patients. Dosage of vitamin E in the study was 600mg per day and the dosage of L-arginine was 6g per day.

Acupuncture

Acupuncture is one of my favourite ways of addressing the issue of a thin endometrial lining. Acupuncture has many benefits for women’s hormonal health. It decreases stress, supports hormone balance, and regulates and increases blood flow to the reproductive organs. Clinical studies have demonstrated an improvement in the thickness of the endometrial lining with regular acupuncture treatments. Points that are often considered include: CV4, CV6, LI10, KI3, SP6, SP10 and ST36. Moxibustion, a warming technique, can also be used in combination with the acupuncture.

Working with a Naturopathic Doctor can help you to develop an individualized plan that will improve your chances of a healthy pregnancy. Additionally, if you difficulty conceiving be sure to have your thyroid thoroughly assessed because low thyroid function is also associated with failure of implantation.   Be sure to work with a Naturopathic Doctor who is experienced in supporting fertility and can help you achieve your goals, naturally.

  1. Hello,
    I’ve been going through IVF for a couple of years now and suffer from a thin uterine lining. We’ve attempted 3 transfers and have had multiple cycles canceled due to my lining. The thickest it has ever been is 7.4mm. I’m starting fertility massages during our next attempt and also bought vitamin e, L-arginine, black cohosh and my physician prescribed estriol cream. My question for you is it okay to try a combination of these remedies at the same time?

  2. Yes and no. Some of the treatments will work well together, like the L-arginine and vitamin E. But once you add in the estriol cream I would discuss with your naturopath whether the black cohosh is still a good idea. Every body is different and there is no one accepted treatment. Also consider acupuncture – I’ve seen that work incredibly well for thin endometrial linings. Good luck! ~Dr. Lisa
