Thin Lining

What is Thin Lining?

The endometrium is the layer of the uterus that thickens in preparation for the implantation of the fertilized embryo. The endometrium is also the layer that is shed during menstruation. Estrogen is responsible for creating a thick, lush and blood-rich endometrium. If estrogen levels are too low or blood flow is inadequate then the uterine lining will remain thin. A healthy adequate uterine lining is at least 8mm thick.

The thickness and quality of your endometrial lining may have an impact on the success of your IVF and your ability to carry a baby to term. Endometrial thickness has been shown to be an important prognostic factor of successful embryo implantation in IVF. In general, as endometrial thickness after IVF stimulation increases, so does pregnancy rate. Endometrial thickness between 6mm-14mm is ideal. Pregnancies do occur when the endometrial thickness is 6mm or 14mm but it seems not as often.

How Chinese Medicine can Help

Our approach at Acubalance is to improve both thickness of lining and quality of endometrial lining. We recommend a combination of acupuncture, Chinese herbs, and supplements for best results.


Acupuncture has been shown to increase blood flow to the lining. One study shows that acupuncture not only thickens endometrial lining but also increases vascularization of the lining as well. It is well-known that a lining can be thick yet not full of life-giving blood (vascularized). Acupuncture can also be used to improve the lining for a frozen embryo or donor treat for 4-5 consecutive days.

At Acubalance, we use a combination of two evidence-based protocols (the Yu Lining and Steiner Impediment protocols) to enhance blood flow and improve lining thickness and quality, thus enhancing implantation and reduce miscarriage rates.



According to Chinese medicine, the food you eat can help or hinder blood flow to the uterus and reproductive organs. You should be eating food rich in iron that nourish the blood. These include beets, spinach, beans, organic grass-finished red meat, pumpkin seeds, molasses, and asparagus. Also, make sure to also include foods that help the absorption of iron, such as oranges, strawberries, broccoli, tomatoes, and green pepper. Consume more blood-invigorating foods during your period such as fish, ginger, cinnamon, and turmeric.



You need to move your body every day in order to promote blood flow to your reproductive organs. It can be as easy as walking for 30 minutes. Walking is simple and moves the hips, allowing blood flow to the uterus. You can also try fertility yoga and abdominal massage. This helps to reduce stress and keep the uterine artery open.

Supplements for thin endometrial lining:

Neo40 daily® (available at Acubalance) is a patented formula that helps to naturally restore and replenish your body’s nitric oxide levels. It is clinically researched to help relax arterial walls and support healthy circulation. Healthy circulation is associated with numerous health benefits, including:


  • Support for healthy blood pressure
  • Support for overall arterial health
  • Support for healthy triglyceride levels
  • May help support sexual performance

Omega 3 fatty acid: some evidence indicates that people with certain circulatory problems, such as varicose veins, may benefit from the consumption of EPA and DHA, which may stimulate blood circulation, increase the breakdown of fibrin (a compound involved in clot and scar formation), and reduce blood pressure.
