If you're preparing for an FET or are pregnant and taking blood thinners, our Gentle Prenatal or Prenatal Essentials for Females would be the most suitable options. These do not contain Vitamin K2 and are designed to be compatible with prescription blood thinners. Our Gentle Prenatal Gummies do have a small amount of K2, which may interact with blood thinners, we recommend consulting with your healthcare provider to determine what's best for you.
