Analysis

The three-capsule serving supplies a broad vitamin profile with methylfolate, methylcobalamin, riboflavin 5-phosphate, pyridoxal 5-phosphate, vitamin D3, vitamin K1, and several trace minerals. Those forms create a capable micronutrient base for general maintenance.

The 495 mg proprietary blend is not broken into ingredients and amounts in the supplied data. That makes the detoxification and targeted balance claims impossible to assess and prevents a complete interaction review.

The formula is more convincing as a broad multivitamin than as a specialized detox product. Three capsules, repeated thiamine listings, a low copper-to-zinc amount, and a relatively high serving cost reduce its practicality.

Who is it for
  • Adults seeking active-form B vitamins
  • Users who want broad trace-mineral coverage
  • People willing to verify the proprietary blend on the current label
Best for
  • General micronutrient maintenance
  • Active B-vitamin intake
  • Vitamin C and trace-mineral coverage

Pros

  • Uses methylfolate and methylcobalamin
  • Includes active riboflavin and vitamin B6 forms
  • Provides vitamin D3 and vitamin K1
  • Covers iodine, selenium, chromium, and molybdenum

Cons

  • Uses an opaque 495 mg proprietary blend
  • Repeats thiamine entries
  • Requires three capsules per serving
  • Offers weak value for the level of disclosure

Warnings

  • The undisclosed proprietary blend prevents a complete medication and allergy review; verify every ingredient on the current package before use.
  • Vitamin K1 can conflict with warfarin dosing, so users taking warfarin should keep intake consistent and follow clinical guidance.
  • The 150 mcg iodine amount may need supervision with thyroid disease or thyroid medicine.

Nutrient quality

76 High impact

The micronutrients are meaningful, but the large proprietary blend cannot be assessed by ingredient. Vitamin D and vitamin E are substantial but not clearly excessive, while hidden blend contents limit a full safety check.

Ingredient transparency

49 Lower impact

Named vitamins and minerals have amounts, but the proprietary blend is disclosed only as a total. The large proprietary blend hides its component ingredients and doses.

Customer satisfaction

64 Moderate impact

The favorable rating is supported by a moderate review base. No review text is available to assess recurring complaints or firsthand results.

Value for money

62 Moderate impact

Good nutrient forms support the cost, but the hidden blend lowers assessable quality. Serving value is fair because a major part of the formula cannot be judged.

Broad vitamin and trace-mineral coverage is well aligned with filling common nutritional gaps. Active B vitamins, vitamin D3, natural vitamin E, and L-selenomethionine strengthen the foundation.

Most nutrients use clear forms and amounts, although B12 and selenium are modest for higher needs. A sizable proprietary blend prevents assessment of its individual ingredients and weakens an otherwise transparent formula. Vitamin K1 can counteract warfarin and other vitamin K antagonist anticoagulants, so users of those medicines should keep intake consistent and coordinate changes with their prescriber.

Vitamins A, C, and D3 with zinc and selenium provide broad, direct immune support. Zinc reaches the preferred amount, while vitamin D3 is substantial and the selenium form is well absorbed.

Vitamin C remains below the focused threshold but still contributes meaningfully. A 495 mg proprietary blend hides its ingredients and doses, reducing confidence in the otherwise high-quality multivitamin base.

Selenium, molybdenum, active B vitamins, and antioxidants provide useful detoxification cofactors. Trace cofactors reach nutritional amounts, but hidden botanicals cannot be checked for effective dosing.

A proprietary blend and general-purpose nutrient design prevent the formula from functioning as a focused liver product. The micronutrients are broadly compatible, though the hidden blend makes the intended detox strategy unclear.

B vitamins and iodine support metabolic and thyroid-related energy processes. Several active vitamin forms improve nutrient quality.

B12 and most B vitamins remain below focused energy thresholds, while a large proprietary blend hides the main specialized actives. The formula appears designed for hormonal balance rather than dependable energy support.

Vitamin C, vitamin D3, natural vitamin E, zinc, selenium, active folate, and d-biotin support follicle nutrition. The biotin amount is modest for targeted use, while zinc reaches a useful maintenance level.

A large proprietary blend prevents assessment of much of the formula. The nutrient base is relevant but lacks disclosed structural proteins or a clearly dosed hormonal active.

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

Potassium iodide provides a stable, water-soluble iodine source without marine contamination concerns. The clearly stated daily amount matches routine maintenance and remains comfortably below the upper intake limit. The serving is moderately priced, and a meaningful selenium dose partly justifies the cost.

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

An amino acid chelate suggests favorable manganese absorption, although the exact amino acid ligand is not named. The 2 mg elemental amount supports maintenance and remains well below excessive intake. A mid-high serving cost is only partly justified by the wider multi-ingredient formula.

A+ Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyF Value
L-selenomethionine provides a highly bioavailable organic source with clear isomer disclosure. The dose is modest for a targeted selenium goal but retains a wide safety margin. Cost efficiency is poor when standardized to a full selenium amount. Value from the broader multi-ingredient formula may still matter beyond selenium alone.
