Analysis

This supplement combines iodine and l-tyrosine with minerals like zinc and magnesium to support thyroid precursors. It also includes bovine thyroid substance, which is a traditional way to provide glandular support for metabolism and energy levels.

By supporting the production of thyroid hormones, this formula contributes to a healthy metabolic rate and systemic drive. It provides a more balanced approach than iodine-only supplements by including necessary mineral cofactors for thyroid function.

Pros

  • Includes mineral cofactors
  • Reasonable iodine dosage
  • Highly transparent label
  • Includes zinc and manganese

Cons

  • Uses bovine glandulars
  • Low tyrosine dose
  • Contains magnesium oxide

Warnings

  • Consult a doctor if you have thyroid disease
  • Not for use with certain medications

Nutrient quality

83 Highest impact

Mineral forms like glycinate and asporotate demonstrate a focus on bioavailability for metabolic support. The 100 mg dose of tyrosine is low for cognitive goals but serves as a supportive addition for thyroid pathways.

Ingredient transparency

99 Highest impact

Labeling is clear regarding the specific minerals and glandular components used. Transparency is good, allowing for a thorough evaluation of the multi-nutrient formula.

Customer satisfaction

90 Highest impact

High ratings indicate that users are satisfied with the product's role in their metabolic wellness routine. Positive feedback supports its effectiveness for maintaining systemic drive.

Value for money

73 High impact

Price per serving is relatively high, which is typical for products containing glandular materials and chelated minerals. Value remains fair for users prioritizing comprehensive glandular support over single amino acids.

A- Goal FitB+ Strength of SupportC CoverageA+ Formula Quality

Thyroid hormone production is directly targeted by 150 mg of bovine thyroid substance and 100 mg of L-tyrosine. Essential mineral cofactors including 150 mcg iodine and 100 mg of absorbable magnesium asporotate support the enzymatic production of metabolic regulators.

Focusing exclusively on the thyroid pathway provides high depth for setting the body's overall metabolic rate. The lack of glycemic-active agents or thermogenics limits its breadth as a comprehensive metabolism-boosting solution.

Potassium Iodide and L-Tyrosine are included to support thyroid hormone production and basal metabolic rate. Thyroid hormones play a mandatory role in governing cellular processes and overall stamina.

The formulation includes Bovine Thyroid Substance for traditional gland support. However, the reliance on glandulars and the use of Magnesium Oxide may limit its effectiveness compared to targeted nutrient-only formulas.
