Epicor Dried Yeast Fermentate
Also known as: EpiCor, postbiotic, dried yeast fermentate, *Saccharomyces cerevisiae*, EpiCor®
Overview
EpiCor® postbiotic is a whole food fermentate derived from the fermentation and drying of *Saccharomyces cerevisiae*, commonly known as baker’s yeast. This ingredient is rich in metabolites such as proteins, polyphenols, vitamins, minerals, amino acids, and polysaccharides, contributing to its health benefits. EpiCor® is primarily recognized for its immune support and gut health properties, commonly found in dietary supplements, nutritional products, and even pet foods. It is non-GMO, vegan, OU Kosher, halal, gluten-free, and free from BSE/TSE, appealing to a broad consumer base. With a shelf life of up to three years, EpiCor® is supported by a growing body of research, including human clinical trials, highlighting its efficacy and safety in health supplementation.
Benefits
EpiCor® postbiotic has demonstrated a range of evidence-based benefits, particularly in immune support and gut health. Clinical trials suggest it significantly reduces cold and flu symptoms, enhances mucosal immune protection, and alleviates gastrointestinal discomfort, with notable effectiveness in reducing allergic rhinitis-induced nasal congestion. Moreover, it has improved gut health metrics, including decreased bloating and gastrointestinal distress. Preclinical studies further support EpiCor®’s anti-inflammatory properties and antioxidant bioavailability, making it notably effective for adults and pets, with a strong evidence base highlighting these benefits.
How it works
EpiCor® postbiotic modulates the gut microbiota by influencing both luminal and mucosal environments. It introduces beneficial metabolites that exhibit prebiotic activity, enhancing immune health through increased diversity and balance of the gut microbiome. This interaction significantly improves immune function while reducing inflammation, despite the specific molecular targets and mechanisms remaining partially understood.
Side effects
EpiCor® postbiotic is generally regarded as safe for consumption, with a wealth of studies indicating no significant adverse effects. Reports of common side effects (>5% incidence) or notable uncommon side effects (1-5%) are absent, and rare side effects (<1%) have not been documented. Currently, there are no known significant drug interactions or contraindications related to EpiCor®, making it suitable for a wide range of populations, including adults and pets. It accommodates diverse dietary restrictions, such as vegan, vegetarian, and gluten-free diets. Continued monitoring of safety data will remain crucial as more individuals incorporate this supplement into their daily routines.
Dosage
The recommended daily dosage of EpiCor® for adults is typically 500 mg, which has shown efficacy in various clinical trials, establishing it as the optimal dose. Daily consumption is advised for sustained health benefits, with the supplement available in tablets, capsules, or as an ingredient in various foods. The unique drying process ensures stability and bioavailability, promoting effective absorption in the body. No maximum safe doses have been established, with long-term studies supporting the safety of continued doses up to 500 mg per day.
