For everyone, adults.
How we verify

The brand submits the formula. We read the supplement facts panel and weigh dose, form and synergy against the clinical evidence. Labs test. IngredientMD verifies. The fee pays for review time, never for the outcome.

How we read this product

Source: Supplement facts
Supplement Facts panel for 5 Defenders Extract
  1. 01
    We read the label.

    The panel on the left is the one we evaluated, line by line.

  2. 02
    Every active, separately.

    All 6 actives checked against the clinical evidence: dose, form, and what the research actually shows.

  3. 03
    Then the formula as a whole.

    Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Stronger in a pair".

  4. 04
    Earned, not bought.

    The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.

Read by the engine against 2.1 million data points from clinical trials, PubMed and more than a hundred vetted sources. No individual reviewer is named or implied.

Systematic review and meta-analysis, 2024
Turkey Tail mushroom extract

Randomised trial, 2004

Four months of a mushroom extract combined with another herb raised immune cell markers in 100 healthy adults, so turkey tail's effect stays unclear.

International Immunopharmacology
Reishi mushroom extract

Randomised trial, 2026

A double-blind trial of a mushroom blend containing reishi reported lower self-rated stress and fatigue and better sleep quality scores than placebo. The blend was tested as a whole.

Brain and behavior
Turkey Tail mushroom extract

Randomised trial, 2026

A randomized trial gave polypore mushroom mycelium, Trametes versicolor included, alongside vaccination and compared antibody and immune cell responses against placebo.

BMC immunology
Maitake mushroom extract

Systematic review, 2009

A systematic search of ten databases found the human research on maitake to be limited and clustered around glucose handling and immune stimulation, with the authors calling for randomised trials.

Journal of the Society for Integrative Oncology
Turkey Tail mushroom extract

Randomised trial, 2014

In 24 healthy volunteers, eight weeks of a mushroom polysaccharide from Trametes versicolor shifted gut bacteria in a pattern typical of a prebiotic, a much smaller shift than an antibiotic comparator produced.

Reishi mushroom extract

Randomised trial, 2024

Older women taking 2,000 mg a day of a Ganoderma lucidum dry extract for eight weeks showed greater lymphocyte proliferation to a laboratory stimulus and a shift in T cell markers toward an anti-inflammatory profile compared with placebo.

British Journal of Nutrition

Meta-analysis, 2015

Across small trials giving adults with raised blood sugar 1.4 to 3 g a day for 12 to 16 weeks, no change in HbA1c was detected (mean difference -0.10 percent, 95% CI -1.05 to 0.85), and total and LDL cholesterol were also unchanged.

Every one of these is a fact the engine could ground.

Each line below was derived from this formula's own record at the time of verification. Nothing here was written by the brand, and nothing can be added that the evidence does not carry.

General timing

How each ingredient usually behaves over time.

Five ingredients, from each one's own page.

  • Turkey Tail mushroom extractAbout two to four weeks

    Digestive changes tend to show in the first two to four weeks. Immune measures are a laboratory readout across a longer stretch rather than a feeling.

    Its own page, the plain answer on timing

  • Reishi mushroom extractTwo to eight weeks

    For the changes trials measure. The settled evening feeling some people describe tends to show up inside the first fortnight.

    Its own page, the plain answer on timing

  • Maitake mushroom extract

    Not an acute ingredient. Colonic fermentation starts within a day, while immune and glucose markers are read across four to eight weeks of daily use.

    Its own page, the plain answer on timing

  • Shiitake mushroom extractWeeks, not days

    Immune measures in studies move across roughly four to eight weeks of daily use, which is where any change shows up rather than in a daily sensation.

    Its own page, the plain answer on timing

  • Chaga sclerotia extractWeeks, not days

    Antioxidant and immune work with chaga reads on lab markers across four to eight weeks rather than as anything on the day.

From the same shelf

Studied alongside this brand's other formulas

Where two of this brand's products carry actives the literature has read together, the pairing and its basis are below. The evidence word is the corpus row's own confidence, never a score.

Cordyceps-M Extract + 5 Defenders ExtractEstablished

Reishi fruiting body extract carries branched beta-1,3/1,6-glucan as a major cell wall constituent, the same structural class recognised by innate immune lectin receptors. Stacking a mushroom extract with a purified glucan means the glucan doses add, which formulators frequently miss when they read the two as separate actives. Total beta-glucan across the formula is the number worth checking.

Established cell wall chemistry: medicinal mushroom extracts are themselves beta-1,3/1,6-glucan sources.. No combination trial has tested this exact pairing.

Cordyceps-M Extract + 5 Defenders ExtractEstablished

Maitake supplies branched beta-1,3/1,6-glucan from its cell wall, structurally closer to yeast glucan than to the linear cereal type. Combining it with a purified glucan raises total intake of the branched class. Whether that produces more receptor engagement depends on particle size and solubility of each preparation, which differ widely between extracts.

Established cell wall chemistry.. No combination trial has tested this exact pairing.

Cordyceps-M Extract + 5 Defenders ExtractEstablished

Turkey tail extracts are characterised by protein-bound beta-glucan fractions, so a formula pairing them with a purified glucan is delivering two preparations of one structural class. The bound protein fraction changes solubility and is why extracts are standardised differently from cereal glucan. Read the combination as additive on total glucan rather than as two distinct actives.

Established cell wall chemistry.. No combination trial has tested this exact pairing.
