Report overview
85 Performance

EpiCor Dried Yeast Fermentate 500 mg

California Gold Nutrition
A quality advantage for buyers seeking a different ingredient balance from Immune Boost is a simple, branded 500 mg EpiCor dried yeast fermentate formula in a longer supply. The substantial daily amount is clearly disclosed, though marker-level fermentate detail is limited.
83 Performance

Wellness EpiCor 500 mg

Source Naturals Wellness
A quality advantage for buyers seeking a different ingredient balance from Immune Boost is 500 mg EpiCor is combined with 50 mcg vitamin D3 in a compact wellness formula. The amounts are clear, but the dry capsule lacks a listed fat carrier and marker-level fermentate detail.
83 Performance

Rapid Immune Defense

Swanson
A quality advantage for buyers seeking a different ingredient balance from Immune Boost is a standalone 500 mg EpiCor serving keeps the active formula direct and easy to assess. The amount is substantial and clearly identified, while marker-level fermentate information remains limited.
85 Budget

EpiCor Dried Yeast Fermentate 500 mg

California Gold Nutrition
Lower recurring cost is the clearest advantage over Immune Boost, while the formula provides a simple, branded 500 mg EpiCor dried yeast fermentate formula. The substantial daily amount is clearly disclosed, though marker-level fermentate detail is limited.
82 Budget

EpiCor Plus Immunity

NOW
Lower recurring cost is the clearest advantage over Immune Boost, while the formula provides 500 mg EpiCor is paired with vitamin C, vitamin D3, zinc bisglycinate, selenium, and olive leaf extract. The broader immune-oriented profile uses a useful zinc form, though the olive-leaf marker amount is modest.
82 Budget

EpiCor 500 mg

Source Naturals Wellness
Lower recurring cost is the clearest advantage over Immune Boost, while the formula provides 500 mg EpiCor is paired with vitamin D3 for focused daily wellness support. Both amounts are clear, but the capsule has no listed fat carrier and the fermentate lacks marker-level detail.
82 Value

EpiCor 500 mg

Healthy Origins
Lower recurring cost paired with a focused 500 mg dried yeast fermentate serving avoids unrelated active ingredients creates a useful value trade-off versus Immune Boost. The amount is substantial, although source and fermentate marker details are limited.
81 Value

Immune & Nasal Defense

Life Extension Florassist
Lower recurring cost paired with 500 mg EpiCor is paired with Lactobacillus rhamnosus CRL 1505 for added nasal and immune-oriented coverage creates a useful value trade-off versus Immune Boost. The bacterial ingredient is listed by weight rather than a viable count, which limits potency assessment.
76 Value

Fermented Beta Glucans

Dr. Mercola
The serving cost does not improve on Immune Boost, but 500 mg yeast fermentate is paired with 400 mg fermented Euglena for broader fermented beta-glucan coverage, which may offer better value for someone seeking that ingredient profile. Strain, production, and active-marker details are limited, so potency is harder to compare.
