Analysis

The capsule combines bovine adrenal and adrenal cortex material with licorice, vitamin C, thiamine, active riboflavin, active B6, pantothenic acid, and zinc bisglycinate. The B-vitamin and zinc forms are generally well chosen.

Licorice is the most important practical concern because it can raise blood pressure and lower potassium in susceptible users. Glandular ingredients add animal-derived material, but the supplied data do not establish the active components or a predictable effect.

It fits only adults who have reviewed the full formula and specifically accept glandular products. People with hypertension, low potassium risk, or relevant medication use have stronger reasons to avoid it.

Who is it for
  • Adults specifically seeking a glandular formula
  • Users comfortable with bovine ingredients
  • People who have reviewed licorice suitability
Best for
  • Targeted glandular supplementation
  • Basic B-vitamin support
  • Chelated zinc intake

Pros

  • Uses P-5-P and active riboflavin
  • Includes zinc bisglycinate
  • Clearly states visible active amounts

Cons

  • Contains licorice
  • Uses bovine glandular materials
  • Pantothenic acid amount is modest
  • Glandular active contribution is uncertain

Warnings

  • Licorice may raise blood pressure or lower potassium
  • Avoid combining licorice with potassium-depleting diuretics without clinician review
  • Bovine glandular ingredients make the product unsuitable for vegetarians and some dietary restrictions

Nutrient quality

71 High impact

The B vitamins and zinc are meaningful, while bovine adrenal and licorice amounts have uncertain practical relevance. Licorice at 75 mg creates a product-specific blood-pressure and potassium concern for susceptible users.

Ingredient transparency

80 High impact

Every listed active ingredient has a specific amount. No proprietary blend hides a listed active dose.

Customer satisfaction

71 High impact

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

Value for money

78 High impact

Good nutrient forms and a focused formula support the cost reasonably well. The long bottle life provides good serving value.

Vitamin B5 · 50 mgRiboflavin · 5 mgThiamin · 10 mg

B vitamins provide modest metabolic support, while the glandular and licorice ingredients are positioned around stress response. Human evidence for bovine adrenal material as an energy aid is weak.

Most nutrient amounts are below focused energy targets, and the glandular ingredients do not disclose functional constituents. Licorice may raise blood pressure or lower potassium in susceptible users.

Report overview
B Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyF Value

Calcium pantothenate supplies a well-absorbed form at the collection median dose. The source and active amount are clear, but additive quality cannot be verified from the provided data. The cost per target B5 amount is high, and 75 mg of licorice may raise blood pressure or lower potassium in susceptible users.

B- Active Ingredient Quality & BioavailabilityB- Dose, Safety & Label TransparencyD- Value

Standard thiamine hydrochloride is clearly identified at a moderate amount. The standard capsule has no documented clean-excipient advantage. High cost per active amount weakens value for targeted thiamin use.
