Analysis

Iodine, selenium, tyrosine, zinc, and magnesium form a credible thyroid-support base, while green tea adds a possible thermogenic pathway. The green tea amount is small and lacks EGCG or caffeine disclosure, limiting its expected metabolic effect.

Tyrosine, selenomethionine, zinc, iodine, and standardized botanical extracts create a coherent thyroid-support formula. The iodine amount is relatively assertive, so people using thyroid medication or managing an overactive thyroid need particular caution.

Selenium, L-OptiZinc, copper, vitamin A, and green tea provide some antioxidant and repair support. The favorable mineral forms are the strongest skin-relevant feature.

Who is it for
  • Adults seeking Metabolism Boost support
  • People comfortable with a multi-ingredient capsule formula
  • Users who can review the ingredient list against medicines and existing supplements
Best for
  • Metabolism Boost
  • General Health
  • Immunity

Pros

  • Iodine, selenium, tyrosine, zinc, and magnesium form a credible thyroid-support base, while green tea adds a possible thermogenic pathway
  • Strongest formulation fit is Metabolism Boost
  • Main label amounts are disclosed for Vitamin A, Vitamin C, Vitamin D3
  • Includes a meaningful Iodine component

Cons

  • clear, but the kelp lacks organic certification or a named clean-water origin
  • Weak fit for Skin Health
  • Several secondary ingredients add breadth without equally strong dose or form support
  • Long ingredient list makes the combined effects and trade-offs harder to predict

Warnings

  • The iodine amount may be unsuitable for some thyroid conditions, so people with thyroid disease should have their iodine intake individualized.

Nutrient quality

75 High impact

Tyrosine, iodine, selenium, and standardized botanicals provide credible thyroid-focused support. Mixed magnesium forms and a substantial iodine amount require more careful use.

.

Ingredient transparency

81 Highest impact

Most active ingredients and their amounts are clearly listed. Daily directions, a complete excipient panel, and some form details are missing from the supplied data.

.

Customer satisfaction

68 High impact

The aggregate rating is favorable and supported by solid feedback volume. Complaint-level experiences are unavailable, so repeated drawbacks and purpose fit remain uncertain.

.

Value for money

80 Highest impact

The serving cost is reasonable for the documented core ingredients. Form, disclosure, or focus limitations keep category value from standing out.

Iodine, selenium, tyrosine, zinc, and magnesium form a credible thyroid-support base, while green tea adds a possible thermogenic pathway. The green tea amount is small and lacks EGCG or caffeine disclosure, limiting its expected metabolic effect.

Several mineral and botanical forms are identified, but magnesium partly relies on oxide and some extracts lack full standardization. People with thyroid disease or thyroid medication should note the 300 mcg iodine dose and guggul before use because both can alter thyroid-related management.

Iodine, selenium, zinc, tyrosine, and selected botanicals form a coherent thyroid-focused combination. These ingredients can support normal thyroid physiology when intake and individual needs are appropriate.

The formula is narrower than comprehensive general-health support, and ashwagandha is present at a modest, incompletely standardized amount. The iodine amount may be unsuitable for some thyroid conditions, so people with thyroid disease should have their iodine intake individualized.

Vitamin A, vitamin D3, zinc, selenium, and vitamin C provide several immune-relevant nutrients within a thyroid-focused formula. The strongest contribution comes from selenium and zinc rather than from the modest vitamin doses.

Standardized ashwagandha, bacopa, green tea, and guggul add specialized thyroid and stress pathways but little direct immune evidence. The substantial iodine amount and ashwagandha can affect thyroid activity, so people with thyroid disease or thyroid-hormone treatment need individual guidance.

Tyrosine, iodine, selenium, magnesium, and ashwagandha support thyroid-related metabolism and stress resilience rather than immediate energy. The formula may be relevant when nutrient status is inadequate, but it is not a general solution for fatigue.

Iodine is relatively high, and magnesium includes poorly absorbed oxide. People with thyroid disease or thyroid medication should review the iodine and gland-focused botanicals with their clinician.

Zinc, selenium, copper, vitamin D3, and thyroid-related nutrients may support hair when thyroid or micronutrient status is limiting. The formula does not contain a structural protein or a direct follicle-growth ingredient.

Its hair relevance is indirect and tied to thyroid nutrition. Iodine and ashwagandha may alter thyroid function, making unsupervised use inappropriate with thyroid hormone medicine or active thyroid disease.

L-tyrosine at 500 mg provides direct support for mental performance during acute stress, while bacopa and ashwagandha add longer-term cognitive and stress pathways. Both botanicals are below common standardized extract targets, and their active percentages are not fully disclosed.

The formula is primarily built for thyroid support rather than brain health, but it contains several relevant cognitive ingredients. The 300 mcg iodine amount deserves care for people with thyroid disease or those using thyroid medication.

Report overview
Iodine (Kelp) · 300 mcg OverallScore82
C+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB+ Value

Kelp provides a whole-food iodine source at the upper end of the preferred daily range. The exact iodine yield is clear, but the kelp lacks organic certification or a named clean-water origin. Selenium and L-tyrosine make the moderately priced formula more relevant for thyroid-focused use.

View ingredientView products
Tyrosine · 500 mg OverallScore76
B- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD- Value

The 500 mg L-tyrosine dose is well aligned with acute cognitive support. The label states the amount clearly, but it supplies no tyrosine-specific purity evidence and offers limited cost efficiency. The 300 mcg iodine dose may complicate thyroid management for people with thyroid disease or those using thyroid medication.

Copper (Copper Gluconate) · 2 mg OverallScore73
C- Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB+ Value

copper gluconate is a common organic salt with moderate absorption potential, and the 2 mg dose exactly matches the collection median. Zinc is low relative to copper, leaving the ratio outside the preferred range. The serving cost is near the collection's typical level, which supports practical value.
