Supplements FAQs

Are Winona’s supplements 3rd-party tested?

Yes. All Winona supplements undergo 3rd-party testing. Each batch is rigorously tested to receive a COA, verifying quality, potency, and purity.

Why choose Winona or this particular product?

Every Winona supplement was physician curated and formulated for essential women's health support, not as a response to the latest trends. We provide a curated selection of the best, most effective products for women.

How are your supplements different from those found on sites like Amazon?

Winona’s supplements are always 3rd-party tested, made with high-quality and transparent ingredients, and designed for women by board-certified physicians. Your health is important, and many women feel safer choosing a trusted source like Winona.

Will these supplements treat my hormonal symptoms?

Winona’s supplements often fill the nutritional gaps that can assist in addressing these concerns, but your health should be approached holistically. If you are of perimenopausal or menopausal age, we suggest exploring HRT to address the root cause of your symptoms.

Everyone’s body, lifestyle, and dietary needs are different. We have a curated selection of supplements that work synergistically. Consult your physician or other qualified healthcare professional before use to determine your ideal regimen.
