The most effective way is to take progesterone capsules or inject progesterone injection to replenish the progesterone in the body; 2. You can appropriately increase the intake of soy foods such as soybeans and black beans, and soy products such as tofu, soy milk and soy skin, which are rich in soy isoflavones and can play a role in replenishing progesterone; 3. You can eat more lemon, kiwi, strawberry and other foods that are rich in bioflavonoids, which have the effect of regulating the level of progesterone.
