Analysis

The one-tablet formula covers common vitamins and trace minerals for routine nutritional support. Iodine, B vitamins, vitamin D, zinc, and chromium address several pathways involved in thyroid function and nutrient-to-energy metabolism.

Fermented iodine glycinate and bisglycinate forms improve mineral specificity compared with vague yeast-bound entries. Chromium remains a maintenance amount, and the small selenium amount provides limited complementary thyroid support.

A 90 mg food-and-herb blend hides its individual ingredients and doses, so it should not be treated as meaningful added support. The product fits broad daily coverage better than focused energy, metabolism, or hormone goals.

Who is it for
  • Men over 40 seeking broad once-daily micronutrient coverage
  • Adults who prefer an iron-free maintenance multivitamin
Best for
  • General nutritional maintenance
  • Supporting thyroid and energy pathways when dietary intake is incomplete

Pros

  • Uses several glycinate and bisglycinate mineral forms
  • Provides broad vitamin and trace-mineral coverage
  • Convenient one-tablet serving

Cons

  • Food-and-herb blend hides individual ingredients and amounts
  • Chromium and selenium offer limited target-specific depth
  • Uses folic acid and cyanocobalamin rather than active alternatives

Warnings

  • Vitamin K can oppose warfarin and other vitamin-K-antagonist anticoagulants, so intake should remain consistent and medically coordinated.
  • The 150 mcg iodine amount may require medical coordination for people with thyroid disease or those using thyroid-hormone or antithyroid medicine.
  • Avoid stacking with another multivitamin because duplicate vitamin A, vitamin D, zinc, and other nutrients can push total intake beyond the intended daily serving.

Nutrient quality

77 High impact

Several glycinate and bisglycinate minerals strengthen form quality, while conventional folic acid and cyanocobalamin remain limitations. Most amounts suit maintenance rather than focused energy or metabolic support, and the food blend adds little depth.

Ingredient transparency

57 Moderate impact

Most active amounts and forms are listed, but duplicate vitamin and chromium entries make totals hard to interpret. The food-and-herb blend hides its components, and inactive ingredients are absent.

Customer satisfaction

71 High impact

Aggregate customer metrics indicate strong satisfaction from a moderate sample. Missing feedback details prevent judging repeated complaints or whether experiences match the intended use.

Value for money

67 High impact

Chelated minerals and broad maintenance coverage provide reasonable value. Moderate serving cost, duplicate entries, and an opaque blend limit competitiveness.

Iodine · 150 mcgVitamin D · 10 mcgVitamin B5 · 10 mgRiboflavin · 3 mgThiamin · 4 mgVitamin B12 · 15 mcg

The 150 mcg iodine amount supports normal thyroid hormone production, while B vitamins provide broader metabolic cofactors. Energy benefit is most relevant when iodine or another included nutrient is inadequate.

The label identifies fermented iodine glycinate and several chelated companion minerals. The broad one-daily formula covers several metabolic needs, though modest doses and an undisclosed herb blend limit depth.

Iodine, chromium, B vitamins, and vitamin D provide broad nutritional support for thyroid, glucose, and energy pathways. Most amounts suit maintenance rather than active metabolic stimulation, and a small proprietary food blend adds little verifiable depth.

The one-tablet format is coherent for nutritional coverage but does not replace focused metabolic actives. Vitamin K can reduce warfarin activity, so users of this anticoagulant need stable intake under medical supervision.

Report overview
A- Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD+ Value

Fermented iodine glycinate gives a clearly identified, nonmarine iodine source at 150 mcg for daily use. Exact dose disclosure and a single tablet make the formula easy to use safely. Cost efficiency is moderate, and the modest selenium amount does not justify an upward value adjustment.

A- Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyD- Value

Fermented bisglycinate provides strong form quality, while no verified branded source is identified. The low amount offers limited support beyond basic nutrition, and the amount remains comfortably within the safety limit. Moderate cost is undermined by the low amount.

F Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

The 60 mcg chromium serving is suited to nutritional maintenance rather than targeted metabolic support. GTF chromium may vary in active content despite listing organic ligands, and no recognized branded source verifies consistency. The broader formula does not include a qualifying high-dose metabolic cofactor for a value adjustment.
