Buying Guide

Check active thyroid-support nutrients

Look for key nutrients such as iodine, selenium, zinc, and B12 listed on the label, since these are commonly used to support thyroid function

Choose the delivery form you’ll take consistently

Select gummies, veggie capsules, or herbal complexes based on preference—Natures Craft offers vegan gummies while several brands provide veggie capsule formats

Consider full-spectrum vs targeted formulas

Herbal complexes (kelp, ashwagandha) provide botanicals in addition to minerals, while targeted formulas focus on specific nutrients like iodine or zinc

Verify third-party testing and brand transparency

Prioritize products from companies that disclose ingredient sources and testing practices to assess purity and potency

Match potency to your needs and healthcare advice

Compare milligram/microgram amounts for iodine, selenium and B12 and consult a clinician to align supplementation with your thyroid status
