Category: Tag:


INDONAL Forte is intended for women:

  • has positive effects during menopause
  • stimulates hormonal balance in women
  • when tissue changes in the cervix and breast cysts occur
  • relieves breast pressure and pain during and outside menstruation
  • The experience of Dr. MUDr. Vladimír Bella, PhD., the Head of the Department of Mammology at the St. Elisabeth Oncology Institute in Bratislava, suggests Indonal is a suitable supportive treatment for breast cancer and reproductive organ cancer
  • Indole-3-carbinol flushes out excess oestrogens that cause • mood swings • stress • sleep disorders • increased sweet cravings • problematic skin.

The packaging contains 90 capsules.

INDONAL FORTE contains Indole-3-carbinol, a substance obtained by gentle extraction from cruciferous vegetables (cabbage, kale, cauliflower, broccoli) and Curcumin complex containing active curcuminoids of Curcuma longa, a plant native to India. Piperine (extracted from black pepper) increases the bioavailability of the main active substances I3C and the curcumin complex in the body.

I3C becomes a very popular natural substance in the prevention of diseases of hormone-dependent tissues (breast, uterus, and ovaries) *1 especially those related to oestrogen metabolism. *3

There are three major oestrogens – oestradiol, oestrone, and oestriol. Oestradiol is responsible for female sexual development, it stimulates growth and function of female reproductive tissues and secondary female sexual characteristics and it regulates skeletal homoeostasis. Independent US studies *2 show that I3C:

  • flushes out harmful oestradiol that increases the risk of cancer
  • stimulates the production of new healthy oestradiol
  • reduces the risk of cancer

Curcumin shows chemopreventive effects in various types of tumour via modulation of biological processes. An important study based on twenty-five patients with several different premalignant or high-risk lesions suggested that oral curcumin may have chemopreventive effects on the progression of these lesions. *4

  7. Oľga

    I have been taking Indonal Forte for 3 weeks. I was diagnosed with ASC-H, HPV 18. A week ago, I had a conization procedure. The healing process is going smoothly without complications. My partner has started taking Indonal Partner. I believe everything will be okay. We will take it as recommended for 3 months. I will inform you about the results after the next testing. Mainly, I hope HPV will stop causing trouble.

  8. Ivana

    After a month of use, I feel better. I believe that with longer use, I will be back to normal.
