insights Analysis
Zoi Research Thyroid Support is formulated to address a wide array of health goals, leveraging a combination of vitamins, minerals, and herbal extracts known for their roles in thyroid health and overall well-being. The inclusion of Iodine, Selenium, L-Tyrosine, Zinc, and Copper directly targets thyroid hormone production and function. Ashwagandha and Bacopa are well-chosen adaptogens that contribute to stress relief, mood, and cognitive function, which are often interconnected with thyroid imbalances. While the blend is comprehensive, certain herbal dosages, such as Ashwagandha and Bacopa, are on the lower end compared to doses typically shown to be highly effective in clinical studies. The Vitamin D3 content is also modest, potentially requiring additional supplementation for optimal levels. The product's price point is mid-range for a multi-ingredient formula, offering a decent balance of cost and benefit, though more potent or specialized alternatives exist for specific needs.
- Contains key thyroid-supporting nutrients: Iodine, Selenium, L-Tyrosine, Zinc, Copper, and Magnesium.
- Includes beneficial adaptogens and herbs like Ashwagandha and Bacopa, which also support stress, mood, and cognitive function.
- Utilizes bioavailable forms for several minerals (Selenomethionine, L-OptiZinc, Magnesium Chelate).
- Addresses a wide range of interconnected health goals beyond just thyroid function.
- Dosages of some herbal extracts (e.g., Ashwagandha, Bacopa, Green Tea) are lower than those typically studied for significant therapeutic effects in clinical trials.
- The Vitamin D3 dosage (10mcg/400IU) is relatively low, especially given common deficiencies and recommendations for optimal levels.
- Magnesium content includes Magnesium Oxide, which has lower bioavailability compared to fully chelated forms.
- Individuals with pre-existing thyroid conditions (hyper- or hypo-thyroidism, autoimmune thyroid disease) should consult a healthcare professional before taking this product due to the iodine content and other active thyroid-influencing ingredients.
- Green Tea extract contains some caffeine, which might be a concern for individuals sensitive to stimulants, although the amount here is relatively low.

bolt Effectiveness for goals
Iodine is a fundamental component required by the thyroid gland to synthesize thyroid hormones, specifically thyroxine (T4) and triiodothyronine (T3). Without adequate iodine, the thyroid gland cannot produce these essential hormones. The body does not produce iodine, so it must be obtained through diet or supplementation.
Selenium is a crucial trace mineral that acts as a cofactor for enzymes involved in thyroid hormone metabolism. It helps convert T4 into the more active T3 form and provides antioxidant protection to the thyroid gland. Adequate selenium intake is important for protecting the thyroid from oxidative stress.
L-Tyrosine is an amino acid that serves as a direct precursor to thyroid hormones. The thyroid gland combines L-Tyrosine with iodine to create T3 and T4. This makes L-Tyrosine a foundational building block for healthy thyroid hormone synthesis.
Ashwagandha is an adaptogenic herb that may help the body manage stress and support endocrine function. Some studies suggest it might positively influence thyroid hormone levels, particularly in individuals with subclinical hypothyroidism, by potentially stimulating thyroid activity. However, more research is needed to confirm these effects.
Zinc is an essential mineral involved in numerous enzymatic reactions, including those necessary for thyroid hormone synthesis and metabolism. It plays a role in the conversion of T4 to T3 and is important for the binding of thyroid hormones to their receptors. Zinc deficiency may therefore impair thyroid function.
schedule Dosage, timing & forms
L-Tyrosine is often suggested to be taken in the morning or early afternoon, as it can be stimulating for some individuals. Ashwagandha can be taken with or without food, and while some prefer it in the evening for its calming properties, others take it in the morning. Individual responses may vary, so it's important to observe how your body reacts.
Magnesium oxide typically contains a high percentage of elemental magnesium but has a relatively lower absorption rate compared to other forms. Magnesium chelates, such as magnesium bisglycinate, are generally well-absorbed and may cause less digestive upset. Combining different forms aims to provide a balance of elemental magnesium content and bioavailability.
Zinc and copper can compete for absorption in the small intestine when taken in high doses at the exact same time. Many supplements formulate these minerals in balanced ratios to minimize competition. If taking separate, high-dose individual supplements, it is sometimes suggested to space them out to optimize absorption of both.
Selenomethionine is an organic and highly bioavailable form of selenium, meaning it is generally well-absorbed and utilized by the body. This form can be incorporated into proteins, potentially leading to better retention and effectiveness compared to some inorganic forms. This contributes to selenium's role in various physiological processes.
Yes, fat-soluble vitamins, including Vitamin D3 and Vitamin A, are best absorbed when taken with a meal that contains some dietary fat. Fat helps with the emulsification and transport of these vitamins through the digestive system. Taking them with food can significantly enhance their uptake and utilization by the body.
health_and_safety Safety & interactions
Individuals with pre-existing thyroid conditions, especially hyperthyroidism or autoimmune thyroid disease, should consult a healthcare professional before taking iodine supplements. Excessive iodine intake can sometimes exacerbate or induce thyroid dysfunction in susceptible individuals. The recommended tolerable upper intake level for adults is 1,100 mcg per day.
Ashwagandha may interact with certain medications, including sedatives, immunosuppressants, and thyroid hormones. It could potentially enhance the effects of sedatives or suppress the immune system. Individuals taking thyroid hormone replacement therapy should be aware that Ashwagandha might affect thyroid hormone levels.
L-Tyrosine is a precursor to thyroid hormones and certain neurotransmitters, so it may interact with thyroid hormone medications. It can also potentially interact with monoamine oxidase inhibitors (MAOIs) due to its role in neurotransmitter synthesis, which could lead to increased blood pressure. Consultation with a healthcare provider is advised if taking these medications.
Gugulipid may interact with certain medications, particularly anticoagulant or antiplatelet drugs like warfarin, due to its potential effects on blood clotting. It may also affect the metabolism of drugs by certain liver enzymes. Discussing supplement use with a healthcare provider is recommended if taking other medications.
While green tea extract is generally safe, high doses of isolated catechins, particularly epigallocatechin gallate (EGCG), have been rarely linked to liver enzyme elevations in sensitive individuals. The amount of polyphenols in this product is relatively low, but individuals with pre-existing liver conditions should exercise caution. It is advisable to follow recommended dosages.
