Terry Naturally Thyroid Care Plus combines L-Tyrosine and Selenium, which are beneficial for thyroid and brain health, with an extremely dangerous dose of Iodine (30,000 mcg). This excessive iodine content far exceeds safe limits and poses significant risks of thyroid dysfunction and other adverse health effects, making the product potentially harmful.

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.
Pros
  • 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.
Cons
  • 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.
Warnings
  • 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.

Report overview

Categories

The inclusion of 400 mg of L-Tyrosine is beneficial, as it is a crucial amino acid for the synthesis of thyroid hormones and neurotransmitters, and this dosage is within a commonly effective range for supporting cognitive function and mood.
The product provides 300 mcg of selenium from yeast, which is a good, bioavailable form. This dosage is generally considered effective for thyroid support, though it is close to the tolerable upper intake level (UL) of 400 mcg, requiring cautious monitoring.
The iodine dosage of 30,000 mcg is extremely and dangerously high, significantly exceeding both the Recommended Dietary Allowance (150 mcg) and the Tolerable Upper Intake Level (1,100 mcg), posing severe risks to thyroid health and overall well-being.

Goals

L-Tyrosine directly supports the synthesis of catecholamines essential for mental clarity and focus. Despite this, the potential for thyroid dysfunction caused by the excessive iodine can lead to significant cognitive impairment and difficulty focusing, negating the desired effect.
L-Tyrosine serves as a precursor for neurotransmitters like dopamine and norepinephrine, which are vital for mood regulation. However, the profound iodine overdose can disrupt overall physiological balance and thyroid function, potentially leading to mood disturbances rather than beneficial support.
L-Tyrosine is a key precursor to neurotransmitters that support brain function. However, the dangerous iodine overdose can lead to thyroid dysfunction, which in turn can severely impair cognitive function, mood, and overall brain health, counteracting any potential benefits from L-Tyrosine.
