      <description><![CDATA[Hello Rachel,

Thank you for your message. In response to your question, no, those who have trouble converting T3 to T4 are very unlikely to know, though they may suspect that if they have a lot of the symptoms associated with hypothyroidism.

As far as thyroid glandulars, there really aren't any vegan alternatives, save for plant-based supplements that feature ingredients like iodine, selenium, zinc, and other nutrients that are essential for thyroid function. Other helpful options include seaweed, such as kelp, dulse, and nori, which are rich in iodine, as well as spirulina and chlorella both of which are nutrient-dense and contain a variety of vitamins, minerals, and antioxidants, including iodine. Incorporating these algae into your diet can help support overall health, including thyroid function. Medicinal herbs like ashwagandha, tulsi, ginseng, licorice root and rhodiola can also really help. You can learn more about each of these supplements benefits through our supplement articles here, <a href="https://www.nationalnutrition.ca/articles/supplements/" rel="noopener" target="_blank">https://www.nationalnutrition.ca/articles/supplements/</a>

Have a healthy day!]]></description>

      <description><![CDATA[Wow! There's a lot to think about when it comes to thyroid health. I wonder if most people who can't convert T3 to T4 are aware of this deficit? Also, thyroid glandular sounds useful but given it's extacted from animals, definitely not suitable for vegans-is there a vegan substitute? Finally, I didn't know that chlorinated and fluoridated water can block iodine receptors in the thyroid-I wonder if perscription high flouride toothpaste could have an adverse effect on the thyroid? Thank you so much for this article. It as very interesting and definitely got my mind turning on the topic of thyroid health!!]]></description>
