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.

Categories
Iodine 85
Contains 300mcg of Iodine from Kelp, a potent and essential dose that is critical for thyroid hormone production. This is a strong point for a thyroid support product, emphasizing its primary function effectively.
Selenium 80
Delivers 100mcg of Selenomethionine, a highly bioavailable and effective form of selenium. This dose is crucial for thyroid enzyme function, antioxidant defense, and overall metabolic health, making it a well-dosed component.
Tyrosine 80
Provides 500mg of L-Tyrosine, which is a substantial and effective dose for supporting thyroid hormone synthesis, as well as neurotransmitter production (dopamine, norepinephrine), contributing well to energy and cognitive goals.
Goals
This is a strong area for the product, as Iodine, L-Tyrosine, Selenium, and Guggul are all directly involved in or support thyroid function, which is the body's central metabolic regulator. Green Tea also adds a modest thermogenic component.
The L-Tyrosine and essential minerals (Iodine, Selenium) directly support thyroid hormone production, which is fundamental for cellular energy metabolism. The B vitamins also contribute to overall energy production, making it a good, non-stimulating, energy support.
Ashwagandha is a well-regarded adaptogen for stress reduction and mood stabilization, helping to modulate the body's stress response. Bacopa also contributes to calming effects, providing solid foundational support for emotional well-being.
