The thyroid gland directly regulates metabolic rate, while sex hormones like estrogen and testosterone also influence how the body stores and uses energy. This is why hormonal shifts often come with metabolic symptoms like weight or energy changes, and vice versa.

If you're primarily noticing weight, energy, or temperature-regulation changes, start with Thyroid & Metabolic Health. If your symptoms are more directly tied to reproductive hormone changes (like perimenopause or low testosterone), start with the relevant hormone-specific collection.

Many people do combine foundational support across categories, but we recommend discussing your full supplement regimen with a healthcare provider, especially if you're managing a diagnosed condition.
