The Polycystic Ovary Syndrome (PCOS) Knowledge Pathway is Updated!


The Polycystic Ovary Syndrome (PCOS) Knowledge Pathway was just updated. Do you know the answers to these questions?
  • In women with polycystic ovary syndrome (PCOS), what dietary interventions are recommended and effective at improving PCOS symptoms?
  • What is the effectiveness of diet and lifestyle interventions for treating adolescents with polycystic ovary syndrome (PCOS)?
  • Are there any dietary supplements (natural health products/functional medicine) that can help manage the symptoms and co-morbidities of polycystic ovary syndrome (PCOS)?

Check out the knowledge pathway for the answers. For more information, see the following PCOS content:

Chronic Disease Prevention and Multivitamin and Mineral Supplementation: What is the Latest?

The Question

What is the safety and efficacy of multivitamin/mineral use for chronic disease prevention in healthy adults?

The Recommendation

Multivitamin and mineral supplementation (including antioxidant mixtures) are generally considered safe for use among healthy adults. However, clinical trials and observational data do not support multivitamin and mineral supplementation for the prevention of chronic disease and associated outcomes in adults, including cardiovascular disease and cancer. Multivitamin and mineral supplementation is therefore not recommended for chronic disease prevention in the general population.
