insights Analysis
Thyroid Care Plus by Terry Naturally aims to support thyroid function and related health aspects like metabolism, brain health, and mood by supplying L-Tyrosine, Selenium, and Iodine. L-Tyrosine is a critical precursor for both thyroid hormones and various neurotransmitters, thereby supporting cognitive and emotional well-being. Selenium is vital for the proper functioning of thyroid enzymes and provides antioxidant protection. However, the formulation includes an extraordinarily high concentration of Iodine at 30,000 mcg (30 mg) per serving. This dosage is approximately 27 times the established UL of 1,100 mcg for adults and 200 times the Recommended Dietary Allowance (RDA) of 150 mcg. Such a profound excess of iodine can be toxic to the thyroid, potentially leading to severe conditions like iodine-induced hyperthyroidism, exacerbating autoimmune thyroiditis, or causing other forms of thyroid dysfunction, significantly undermining the product's stated goals and presenting a serious health hazard. While the Selenium and L-Tyrosine dosages are reasonable and beneficial independently, the critical iodine overdose completely overshadows these positive aspects, making the product highly risky.
- Contains L-Tyrosine, an amino acid vital for neurotransmitter and thyroid hormone synthesis, potentially supporting mental focus and mood.
- Includes Selenium from yeast (Saccharomyces cerevisiae), a bioavailable form of an essential mineral crucial for thyroid enzyme function and antioxidant protection.
- The L-Tyrosine dosage (400mg) is within a common and generally effective range for cognitive support.
- Features an extremely high and unsafe dosage of Iodine (30,000 mcg), which is significantly above the recommended daily intake and tolerable upper limit, posing severe health risks.
- The dangerously excessive iodine content can induce or worsen thyroid dysfunction, directly counteracting the product's intended purpose.
- The high dose of iodine can lead to serious adverse effects like iodine-induced hyperthyroidism or exacerbation of autoimmune thyroid conditions.
- Consult a healthcare professional immediately before using this product, especially if you have any pre-existing thyroid conditions, as the iodine content is critically high and potentially dangerous.
- Discontinue use and seek medical attention if you experience symptoms of thyroid dysfunction, such as palpitations, unexplained weight changes, anxiety, or fatigue.
- This product is not recommended for individuals without explicit medical supervision due to the severe risk associated with iodine overdose.

bolt Effectiveness for goals
L-Tyrosine is an amino acid that serves as a fundamental building block for the synthesis of thyroid hormones. Specifically, it combines with iodine to form thyroxine (T4) and triiodothyronine (T3). This process is crucial for maintaining normal metabolic function.
Selenium is an essential trace mineral critical for the proper functioning of the thyroid gland. It is a component of selenoproteins, which include enzymes involved in thyroid hormone metabolism and antioxidant defense within the thyroid. These enzymes help convert T4 into the more active T3 hormone.
Iodine is a vital trace element that the thyroid gland actively absorbs from the bloodstream. It is directly incorporated into the structure of thyroid hormones, specifically L-Tyrosine residues, to create thyroxine (T4) and triiodothyronine (T3). Without adequate iodine, the body cannot produce these essential hormones.
L-Tyrosine and iodine are both direct precursors for thyroid hormones. The thyroid gland uses L-Tyrosine as a structural base and then attaches iodine atoms to it in a series of enzymatic reactions. This combined process is necessary to form both T4 and T3, which regulate metabolism.
Yes, selenium plays a crucial role in conjunction with iodine and L-Tyrosine. Selenium-containing enzymes protect the thyroid gland from oxidative stress that can occur during hormone synthesis, particularly when iodine is processed. It also facilitates the conversion of inactive T4 to active T3, optimizing the utilization of the hormones built from L-Tyrosine and iodine.
schedule Dosage, timing & forms
L-Tyrosine serves as a primary building block for thyroid hormones. Iodine is a crucial component that directly forms part of these hormones. Selenium is essential for the enzymes that convert inactive thyroid hormone (T4) to its active form (T3) and helps protect the thyroid gland from oxidative stress.
L-Tyrosine is generally suggested to be taken on an empty stomach to enhance its absorption and prevent competition with other amino acids. This typically means 30-60 minutes before a meal or at least two hours after. However, individual product instructions may vary.
Yeast-bound selenium is a common organic form, primarily selenomethionine, which is generally considered to have good bioavailability. This means it is efficiently absorbed and utilized by the body. Organic forms of selenium are often preferred for their stability and absorption characteristics.
Iodine is indispensable for the synthesis of thyroid hormones, while selenium is crucial for the activity of deiodinase enzymes, which convert thyroid hormones into their active forms. Selenium also offers antioxidant protection to the thyroid gland, making their combined action synergistic for thyroid health.
While L-Tyrosine is often absorbed best on an empty stomach, taking iodine and selenium with food can sometimes help minimize potential digestive upset. For optimal timing and to avoid interactions, it is generally recommended to follow specific product instructions or consult with a healthcare professional.
health_and_safety Safety & interactions
Consuming significantly high doses of iodine, such as 30,000 mcg, can lead to adverse effects on thyroid function in some individuals. These effects may include developing or worsening hypothyroidism or hyperthyroidism, and can also contribute to goiter. It is important to consult a healthcare professional to determine appropriate iodine intake.
Yes, high doses of iodine can potentially interfere with the effectiveness of thyroid hormone medications, or exacerbate existing thyroid conditions. Individuals taking thyroid medication should discuss their iodine intake with a healthcare provider. This ensures proper management of their thyroid health and avoids potential complications.
Individuals with pre-existing thyroid conditions, such as Hashimoto's thyroiditis or Graves' disease, should exercise caution with supplements containing these ingredients. High doses of iodine, in particular, can significantly impact thyroid function. Consulting a healthcare provider is recommended to assess suitability and monitor thyroid health.
L-tyrosine may potentially interact with certain medications, including MAO inhibitors, thyroid hormones, and levodopa. These interactions could affect medication efficacy or lead to adverse effects. Individuals taking prescription drugs should discuss supplement use with their doctor.
While 300 mcg of selenium is below the typical tolerable upper intake level of 400 mcg, very high selenium intake can lead to selenosis with symptoms like hair loss and brittle nails. At 300 mcg, it is generally considered safe for most adults. However, individuals should monitor for any unusual symptoms.
