  • Designed for Women, by Women.

    THYR was born from listening to women who've felt invisible in their own bodies. Women over 35 experiencing thyroid symptoms weren't being heard -dismissed as stressed, told to lose weight, or given prescriptions without understanding. We designed THYR differently. Every ingredient was chosen by women who understand what it feels like to wake up exhausted, to lose focus mid-conversation, to feel your body working against you. This isn't guesswork. It's built on what women actually need."

  • Science-Backed Ingredients, Not Hype

    Most thyroid supplements throw 15 ingredients at you and hope something sticks. THYR is different-we chose three mechanisms of support: Metabolism Support to help your body process thyroid hormones efficiently, Hormone Balance to support your natural rhythm, and Energy & Vitality because feeling alive matters. Every ingredient was selected based on published research and real-world evidence. We're not promising miracles. We're backing what works with the science women deserve to trust.

  • From the UK, For Your Life

    We're based in the UK, and we understand your climate, your routines, your health culture. THYR was formulated with the British lifestyle in mind-from the water you drink to the seasons that affect your energy. We don't source random international ingredients and hope they work in your body. We test, we listen to the women using THYR, and we refine. You're not buying a trend. You're buying something made by people who live in your world.
