Product analysis

51 out of 100

DefensePlus lists its ingredient amounts clearly, but unspecified herbal and mushroom preparations make it difficult to compare the formula with alternatives.

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

Nutrient Quality24

Most herbal and mushroom preparations are unspecified, which limits quality comparisons. The named vitamin C and zinc forms also lack enough information for a confident quality assessment.

Ingredient Transparency69

The listed ingredient amounts are disclosed. Most herbal and mushroom forms are unspecified, making similar quantities difficult to compare across brands.

Value For Money57

The serving price compares favorably for the ginger and maitake ingredients. Value for the other ingredients remains uncertain, so the price alone cannot establish value for the whole mix.

Customer Satisfaction92

Customers report very high satisfaction across a large review pool. The breadth of feedback makes the satisfaction picture more informative, without proving effectiveness.

Product Focus35

The formula combines many nutrients, herbs and mushrooms, making its purpose less focused. Specific benefits cannot be judged confidently from the available information.

Shiitake Maitake 250 mg

Nature's Way
Clearly dosed maitake and shiitake extracts provide a concise alternative to the original’s lightly dosed multi-botanical blend. Polysaccharides are named, but mushroom parts, extraction method, and beta-glucan yield remain missing.
79 Performance

M/R/S Mushroom Formula

Pure Encapsulations
Equal amounts of maitake, reishi, and shiitake fruiting-body extracts provide stronger mushroom-part disclosure and focused coverage. Extraction method and beta-glucan yield are still unknown, and the formula omits vitamin C, zinc, ginger, and astragalus.
79 Performance

Reishi Shiitake Maitake Mushroom Extract

Solgar
Organic reishi, shiitake, and maitake extracts provide a focused mushroom blend, with extra reishi marker details improving confidence. Maitake and shiitake remain modest, while mushroom parts and extraction methods are unclear.
79 Budget

Rei-Shi Mushrooms 270 mg

NOW
Reishi powder and extract with shiitake provide focused mushroom coverage at lower serving cost than the broad immune blend. Missing fruiting-body, extraction-ratio, and standardization details limit confidence in potency.
72 Budget

Immune Action

NaturesPlus
Astragalus, shiitake, echinacea, schisandra, and ligustrum preserve a broad botanical immune strategy at lower serving cost. Most amounts are modest and the label lacks plant parts, extract details, and active-marker standardization.
73 Budget

Mushroom Immune Complex with Maitake Reishi & Shiitake

Solaray
Maitake, reishi, and shiitake provide a coherent mushroom formula with favorable serving economics and disclosed species. Repeated entries make totals less clear, while mushroom parts, extraction, and beta-glucans are missing.
76 Value

Immune Essentials Comprehensive Formula

Swanson
Larch arabinogalactan, bovine colostrum, oat beta-glucan, elderberry, maitake, and shiitake provide broad immune coverage with good serving value. The mushrooms are lightly dosed and bovine colostrum makes the formula unsuitable for people with a milk allergy.
72 Value

Beyond Wellness

KAL
Buffered vitamin C, zinc picolinate, echinacea, standardized andrographis, elderberry, astragalus, and mushrooms create broad immune support with clearer marker disclosure. Many mushroom and herbal additions are modest, but the core actives provide reasonable effective value.
75 Value

Brain & Body

Host Defense MycoBotanicals
Substantial lion’s mane plus turmeric, reishi, ginger, cinnamon, and black pepper provide broader mushroom and botanical depth than the original’s many small additions. Active-marker and processing details are limited, but the disclosed amounts support fair value for broad use.
