Analysis

Black-cohosh extract at 80 mg and soy isoflavones at 60 mg form the main menopause-support combination. Green tea, yerba mate, magnolia bark, and a small calcium amount add energy or calming pathways around that core.

No active standardization is provided for black cohosh, soy isoflavones, or the tea extracts. Caffeine is not quantified, making it hard to judge whether yerba mate and green tea will support energy or cause sleep and tolerance problems.

One tablet and good value make the formula practical for users who want this exact combination. Its mixed stimulating and calming ingredients need individualized timing, and the product is not a general green-tea supplement.

Who is it for
  • Menopausal adults seeking black cohosh and soy isoflavones
  • People wanting a one-tablet daytime formula
Best for
  • Menopause-oriented support
  • Soy-isoflavone intake
  • Daytime botanical routines

Pros

  • Meaningful black-cohosh and soy-isoflavone amounts
  • One-tablet serving
  • Good value
  • Includes both energy and calming botanicals

Cons

  • No active standardization details
  • Caffeine amount is not disclosed
  • Calcium amount is nutritionally small
  • Mixed mechanisms complicate timing

Warnings

  • Black cohosh has occasionally been linked with liver injury; stop use for jaundice, dark urine, or persistent upper-abdominal pain.
  • People with estrogen-sensitive conditions should discuss black cohosh and soy isoflavones with their clinician before use.
  • Green tea and yerba mate may supply caffeine and can worsen insomnia, palpitations, or anxiety.

Nutrient quality

64 Moderate impact

Most botanical extracts lack marker standardization, while calcium uses a basic form. Core menopause ingredients are meaningful, but poorly characterized botanicals and modest green tea weaken quality.

Ingredient transparency

79 High impact

Every listed active has a stated amount. No proprietary blend hides the listed active doses.

Customer satisfaction

62 Moderate impact

The supplied average is positive, with limited response volume. Complaint patterns and purpose-related experiences are not supplied.

Value for money

50 Moderate impact

The asking price is only partly justified by the disclosed formula. Serving value is weak relative to the green tea support provided.
