Is there any special nutritional support for ovarian cysts?

Ovarian cysts: Nope, it would be nice if there was. Unless you consume a diet high in phyto-estrogens (for example), your diet will not affect ovarian function at all. Even if you do consume plant Estrogens and the like, it will affect your cycle in an unpredicatble way, not as 'support.'.

Healthy diet: There is a lot of dietary advice for ovarian cysts, though I have found little research to support it. Common advice is to avoid sugar and simple carbs, emphasize fruits & vegies, esp. Dark leafy greens, & minimize meats & dairy, esp. If not organic (to avoid hormones & antibiotics in meats). Some advise an alkaline diet & foods rich in phytoestrogens. See my comments for more information & links:.

If PCOS...: It is a part of metabolic syndrome usually. Woen with pcos need to adhere to a low glycemic lifestyle, not only to improve this situation, but the other issues, high blood pressure. Dyslipidemia, diabetes, thaat can be around the bend! proper nutritional support is essential.

Yes: Ovarian cysts are due to excess Insulin and iodine deficiency. So taking nutrients that help control Insulin including chromium, cinnamon, thiamine and such are helpful plus additional iodine.
