About this product

Vitamin C, vitamin D3, and zinc bisglycinate cover several foundational nutrient pathways involved in normal immune function. Their amounts are clearly stated, and the chelated zinc form is a notable quality strength.

Astragalus adds 500 mg of botanical support without being hidden in a proprietary blend. Species, plant part, extraction method, and marker content are not supplied, so its individual potency remains uncertain.

The one-tablet formula suits adults who want broad daily immune support without an oversized ingredient list. It is less suitable for users who need a fully standardized astragalus extract or who already take overlapping vitamin D or zinc.

Who is it for
  • Adults seeking broad daily immune support
  • People who want nutrients plus one botanical
  • Users who prefer a single daily tablet
Best for
  • Foundational immune-nutrient coverage
  • Combining zinc and vitamin D with astragalus
  • Simple multi-pathway routines

Pros

  • Includes vitamin C and vitamin D3
  • Uses zinc bisglycinate
  • Provides a substantial astragalus amount

Cons

  • Astragalus species and plant part are missing
  • No astragalus extraction or marker details
  • May overlap with separate vitamin D or zinc supplements

Warnings

  • Astragalus may conflict with immunosuppressant medicines because it can affect immune activity.
  • People with autoimmune conditions should review the formula with their clinician.
  • Count its vitamin D and zinc when combining it with other supplements to avoid unnecessary duplication.

Product analysis

70 out of 100
A well-balanced daily immune formula with vitamin C, vitamin D3, chelated zinc, and a meaningful astragalus amount. Astragalus quality detail is the main limitation.

AI assessment of the formula, label and price. How scoring works

Nutrient quality69

A clear amount is supplied, but the astragalus form, species, root source, and marker quality are vague. The supplied amount supports practical use for focused use.

.
Ingredient transparency77

The main active amounts are clearly listed, making the core formula possible to assess. Intake directions, non-active ingredients, and key botanical-quality details are absent from the supplied data.

.
Customer satisfaction65

The supplied average is very strong and the response volume is limited. No detailed feedback is provided to assess recurring complaints or fit with the intended purpose.

.
Value for money64

The serving may be economical, but incomplete botanical verification limits confidence in value. A better specified or more concentrated astragalus product would provide a stronger comparison.
