Analysis

Astragalus at 200 mg is the lead ingredient, followed by 100 mg each of ligustrum, schisandra, shiitake, and echinacea. The species is supplied for several botanicals, improving basic identity transparency.

Plant parts, extraction ratios, and active-marker levels are not stated. Shiitake also lacks mushroom-part, extraction, and beta-glucan details, so the 100 mg amount is difficult to interpret.

A one-capsule serving and 120-serving bottle provide excellent convenience and low cost. The formula offers traditional ingredient breadth but not the depth of standardized astragalus or mushroom extracts.

Who is it for
  • Adults seeking an economical traditional immune blend
  • People who prefer one capsule daily
  • Users comfortable with modest botanical doses
Best for
  • General botanical immune support
  • Long-serving-count daily routines
  • Combining astragalus with schisandra and echinacea

Pros

  • Provides 120 servings
  • Low serving cost
  • Includes six complementary botanicals
  • Names species for several ingredients

Cons

  • Astragalus amount is modest
  • Extract and active-marker details are absent
  • Shiitake source quality is unclear
  • Plant parts are mostly not disclosed

Warnings

  • Astragalus, echinacea, and shiitake may not suit people using immunosuppressant medicines
  • Echinacea may trigger reactions in people sensitive to ragweed-family plants
  • Schisandra can alter medication metabolism
  • Pau d'arco is generally avoided during pregnancy and may increase bleeding tendency

Nutrient quality

63 Moderate impact

Several species are named, but plant parts, extraction methods, and active-marker strengths are missing. Astragalus is modest and the other botanicals are low for focused use.

Ingredient transparency

78 High impact

Every listed ingredient has an individual amount. Excipients and daily directions are absent from the supplied data, which leaves some label details uncertain.

Customer satisfaction

68 High impact

The aggregate satisfaction average is strong, though no detailed feedback is supplied. The moderate volume provides a reasonably useful aggregate satisfaction signal.

Value for money

77 High impact

The coherent blend offers reasonable quality despite modest dose depth. The low serving cost supports good value for broad botanical coverage.

F Active Ingredient Quality & BioavailabilityB Dose, Safety & Label TransparencyC Value

The exact Astragalus amount is disclosed within a multi-herb blend, but the serving is modest for a non-standardized botanical. A species name is supplied, while the plant part, extract type, active markers, and organic status are missing. Its cost efficiency is moderate, and the added botanicals do not resolve the limited Astragalus potency details.
