Product analysis

51 out of 100

DefensePlus brings together vitamin C, zinc, herbs and mushrooms in one supplement. Most botanical preparations are unspecified, making it hard to compare what they provide with other options.

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

Nutrient Quality24

The botanical preparations are mostly unspecified, limiting useful quality comparisons. Named vitamin C and zinc forms do not by themselves establish a quality advantage.

Ingredient Transparency69

Every ingredient amount is stated, making serving comparisons possible. Most forms are omitted, leaving important details about the herbs and mushrooms unclear.

Value For Money57

The low serving cost is favorable when considering the ginger and maitake. Value is less certain for the other ingredients.

Customer Satisfaction92

Customer satisfaction is very high across thousands of ratings. The large feedback base offers a broad view of satisfaction, without proving health benefits.

Product Focus35

The wide ingredient mix makes the formula complex. Specific health benefits cannot be established confidently from the combination.

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.
