insights Analysis
This 'Thyroid Care' product combines L-Tyrosine (400mg) with a profoundly excessive dose of iodine (30,000 mcg). While L-Tyrosine is a valuable amino acid for supporting thyroid hormone synthesis and neurotransmitter production, the iodine content is the primary and most concerning aspect. The Recommended Dietary Allowance (RDA) for iodine is 150 mcg for adults, and the Tolerable Upper Intake Level (UL) is 1,100 mcg. Consuming 30 mg of iodine daily is nearly 30 times the UL, a level widely considered dangerous by mainstream nutritionists and medical professionals. Such high doses can lead to severe thyroid imbalances, including both hyperthyroidism (Jod-Basedow phenomenon) and hypothyroidism (Wolff-Chaikoff effect), particularly in susceptible individuals. Online reviews may vary, but the scientific evidence strongly cautions against iodine intake at this magnitude without direct and intensive medical supervision and specific clinical indication, which is rare. The potential benefits from L-Tyrosine are overshadowed by the significant health risks posed by the iodine dosage.
- Contains a moderate and generally beneficial dose of L-Tyrosine (400mg) which is a precursor to thyroid hormones and neurotransmitters.
- The iodine content of 30,000 mcg (30mg) is an extremely dangerous dose, far exceeding the Tolerable Upper Intake Level (UL) by nearly 30 times.
- High iodine intake at this level can severely disrupt normal thyroid function, potentially causing iodine-induced hyperthyroidism or hypothyroidism.
- Poses significant risks to overall health and endocrine balance, making it unsuitable for most individuals.
- The risk profile associated with the iodine dose overshadows any potential benefits from the L-Tyrosine.
- Individuals should NOT take this product without explicit medical advice and supervision from a qualified healthcare professional.
- Those with pre-existing thyroid conditions, such as Hashimoto's or Grave's disease, are at extremely high risk of severe adverse reactions from this iodine dosage.
- Monitor closely for symptoms of thyroid dysfunction, including rapid heartbeat, anxiety, unexplained weight changes, fatigue, or mood swings.
- This product's iodine content is far above general health recommendations and may cause more harm than benefit.

bolt Effectiveness for goals
Iodine is an essential trace element crucial for the production of thyroid hormones. These hormones regulate metabolism, growth, and development. Adequate iodine intake is vital for proper physiological function.
Iodine is crucial for the thyroid gland to produce hormones, specifically thyroxine (T4) and triiodothyronine (T3). These hormones are vital for regulating metabolism, growth, and development throughout the body. Adequate iodine intake is essential for preventing iodine deficiency disorders, including goiter and hypothyroidism.
Iodine is a fundamental component of thyroid hormones (T3 and T4), which are synthesized by the thyroid gland. Adequate dietary iodine ensures the thyroid can produce these hormones effectively. Supplementation can help prevent deficiencies that impair thyroid function.
L-Tyrosine is an amino acid that serves as a precursor to several important neurotransmitters, including dopamine, norepinephrine, and epinephrine. It is often used to support cognitive function, particularly under stress, and may assist with alertness and focus. Some also use it for mood support.
Iodine and tyrosine are both crucial for the production of thyroid hormones. Tyrosine is an amino acid that forms the backbone of these hormones, while iodine atoms are attached to this tyrosine structure to create T3 and T4. Their combined presence is essential for healthy thyroid function.
schedule Dosage, timing & forms
The recommended daily allowance (RDA) for iodine in most adult populations is 150 micrograms (mcg). This amount is generally sufficient to prevent iodine deficiency in healthy individuals. Pregnant and lactating women have higher recommended intakes.
For most adult men and women, the recommended dietary allowance (RDA) for iodine is 150 micrograms (mcg) per day. Pregnant and lactating individuals have higher recommendations. It's advisable to consult a healthcare professional for personalized guidance.
Typical dosages for L-Tyrosine supplements vary widely depending on the intended use, often ranging from 500 mg to 2000 mg per day. These amounts are often divided into multiple doses throughout the day. It is generally recommended to start with a lower dose and adjust as needed.
The Tolerable Upper Intake Level (UL) for iodine for adults is generally set at 1,100 micrograms (mcg) per day. Consuming iodine above this level regularly can lead to adverse effects, especially for individuals with pre-existing thyroid conditions. It's important not to exceed recommended doses without medical supervision.
Long-term intake of excessively high doses of iodine can be harmful and may lead to thyroid dysfunction, including both hyperthyroidism and hypothyroidism. The Tolerable Upper Intake Level (UL) for adults is 1,100 micrograms (mcg) per day. Doses above the UL should only be considered under medical supervision for specific conditions.
health_and_safety Safety & interactions
Both iodine and tyrosine are precursors for thyroid hormone synthesis, and they can generally be taken together. However, individuals with pre-existing thyroid conditions should consult a healthcare provider due to their combined potential impact on thyroid function. Monitoring may be recommended.
Since both nutrients are crucial for thyroid hormone production, their combined use could potentially overstimulate thyroid function in susceptible individuals, particularly those with underlying thyroid conditions. Monitoring thyroid hormone levels might be advisable. It's important to consult with a healthcare professional to determine appropriate dosages and assess individual risk.
Excessive iodine intake can lead to thyroid dysfunction, including both hyperthyroidism and hypothyroidism. Symptoms may include a metallic taste, nausea, vomiting, diarrhea, and a burning sensation in the mouth or throat. Long-term high intake can also cause goiter or thyroiditis.
High doses of tyrosine are generally well-tolerated, but some individuals may experience mild side effects such as nausea, heartburn, fatigue, or headache. More significant side effects are uncommon but can occur, especially with very high doses.
Yes, iodine can interact with certain medications. These include antithyroid medications (like methimazole), ACE inhibitors, and potassium-sparing diuretics, potentially affecting thyroid function or potassium levels. It is advisable to consult a healthcare provider if taking medications.

Tyrosine 80.0
The 400mg dose of L-Tyrosine is a well-established and effective quantity for supporting neurotransmitter synthesis and thyroid function, making it a valuable component of this product in terms of its standalone contribution.
Iodine 5.0
While the product contains iodine, the dosage of 30,000 mcg is astronomically high and unsafe for routine supplementation, significantly exceeding therapeutic and regulatory guidelines, thus posing substantial health risks rather than simply providing a beneficial source of iodine.
