Nutrients connected to Fertility Support

A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.

• Chitrak (Ceylon leadwort)Documented risk

  Animal findings of anti-implantation, sperm-reducing and anti-androgen effects mean it is not a fertility aid and is a concern when trying to conceive.

• SeleniumEstablished role

  The NHS lists reproduction among the things selenium helps with. We did not read evidence that supplements improve fertility in people with adequate intake.

• OshaDocumented risk

  Osha is traditionally avoided in pregnancy because it may induce menstruation; AHPA recommended a not-for-pregnancy label in 1997. Not studied for fertility.

• Cuscuta seed (tu si zi)Preliminary or mixed

  Seed-containing formulas are used for infertility and show promising but limited results; trials of the seed alone are lacking.

• Thunder god vineDocumented risk

  Not a fertility aid. Menstrual cycle changes are listed as a side effect and it is unsafe in pregnancy.

• Cynomorium (Suo Yang)Lab or animal research only

  A mouse study of flavonoids reported protection against chemotherapy-induced reproductive damage; no human data found.
