Analysis

Zinc bisglycinate, L-selenomethionine, manganese citrate, and chromium nicotinate glycinate are well-chosen forms. The amounts are clearly stated and suit focused daily trace-mineral coverage without an overloaded ingredient list.

Zinc and selenium provide the strongest nutritional contribution, while manganese, chromium, and boron broaden enzyme and metabolic support. Copper is absent, so this is not the most balanced choice for indefinite use when dietary copper is low.

The concise capsule formula is easier to evaluate than products padded with hidden blends. It fits users who want quality trace-mineral forms, but it does not replace major minerals, vitamins, or a complete multivitamin.

Who is it for
  • Adults seeking premium trace-mineral forms
  • People who want focused zinc and selenium support
  • Users whose vitamins and major minerals are covered elsewhere
Best for
  • High-quality trace-mineral supplementation
  • Daily zinc and selenium support
  • A concise formula without proprietary blends

Pros

  • Uses TRAACS zinc and chromium chelates
  • Provides L-selenomethionine
  • Clearly discloses every active amount
  • Focused formula avoids decorative blends

Cons

  • Does not include copper alongside 15 mg zinc
  • Does not cover vitamins or major minerals
  • Selenium-specific value is less compelling than the full blend value

Warnings

  • Long-term daily use of 15 mg zinc without copper may be poorly balanced for people with low dietary copper
  • Count the 100 mcg selenium serving when combining it with other selenium supplements

Nutrient quality

95 Highest impact

Several nutrients use well-absorbed organic or active forms. The key nutrients have meaningful amounts for the formula’s intended use.

Ingredient transparency

84 Highest impact

The listed active nutrients have specific amounts. A complete inactive ingredient list is not supplied.

Customer satisfaction

92 Highest impact

The aggregate customer rating is exceptionally strong. Specific experiences are absent, but the aggregate rating is broadly consistent with satisfaction.

Value for money

96 Highest impact

The price is supported mainly by useful core nutrients. The nutrient forms and breadth strongly support qualitative value.

Five trace minerals support immune, antioxidant, metabolic, and enzyme functions. The use of bisglycinate, selenomethionine, citrate, and nicotinate glycinate forms strengthens the formula.

Amounts are clearly disclosed and generally suited to filling everyday nutritional gaps. The focused trace-mineral design does not replace major minerals or a complete multivitamin.

Bioavailable zinc and selenium provide direct support for immune-cell activity and antioxidant defense. Manganese, chromium, and boron broaden trace-mineral coverage without overwhelming the core formula.

The 15 mg zinc amount meets the goal target, and all mineral forms and amounts are clearly disclosed. Users combining several selenium products should account for the additional 100 mcg serving.

Report overview
Manganese (Manganese Citrate) · 2.5 mg OverallScore82
B+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB+ Value

The focused trace-mineral formula combines a practical maintenance amount with a favorable citrate source. The elemental amount is suitable for daily maintenance but modest for targeted bone or joint support. The economical serving cost supports strong manganese-specific value.

Selenium (L-Selenomethionine) · 100 mcg OverallScore81
A+ Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyF Value

L-selenomethionine provides a well-absorbed organic selenium source with clear isomer labeling. The 100 mcg amount suits daily maintenance and leaves a comfortable safety margin. Its selenium-specific cost is relatively high, though added trace minerals provide broader value.

Chromium (TRAACS Chromium Nicotinate Glycinate Chelate) · 100 mcg OverallScore65
A+ Active Ingredient Quality & BioavailabilityD- Dose, Safety & Label TransparencyD- Value

TRAACS chromium nicotinate glycinate provides a branded, highly bioavailable chelate. The amount sits at the bottom of the low-dose band, and the label does not separate compound weight from elemental yield. A moderate normalized cost provides fair value within a broader trace-mineral formula.
