Doctor's Best Postbiotic – 60 vegetarian capsules
★★★★★— SmallsamThe capsules are a standard size and easy to swallow. I noticed a subtle change in my digestive regularity. No immediate, dramatic changes in immune function, but a sense of improved overall gut comfort. No adverse reactions, such as gas or bloating. The 500 mg dosage seems reasonable. I would consider it for maintaining gut flora and potentially supporting immune function. The product is tasteless, which is a plus. The packaging is practical. I noticed a slight reduction in occasional digestive discomfort.

Description
Product overview
Doctor's Best Immune Support Postbiotic is a food supplement in the form of vegetarian capsules containing 500 mg of EpiCor® per serving. EpiCor® is a fermented, yeast-based postbiotic substance made from Saccharomyces cerevisiae, a yeast strain with a long history of use in food production. The product comes in a pack of 60 capsules, providing a convenient and straightforward option for daily use. Doctor's Best has a strong track record in science-based food supplements, combining modern research with natural ingredients to create products suited to different lifestyles. With a focus on purity and quality, this postbiotic formula is designed to suit vegans and people with specific dietary requirements, as it is free from gluten and GMOs.
Active ingredients & science
The main ingredient in this product is EpiCor®, a dried and fermented substance from the yeast strain Saccharomyces cerevisiae. Unlike probiotics, which contain live microorganisms, postbiotics consist of yeast metabolites and cell components that the body can utilise. These bioactive substances, which include beta-glucans and polysaccharides, are produced through controlled fermentation processes to ensure stability and bioavailability. This method means the product can provide a reliable, long-lasting source of postbiotic components without depending on live bacteria surviving in the stomach.
Benefits & uses
- Gentle on sensitive stomachs: As the product contains no live bacteria, it may be suitable for people who have difficulty tolerating probiotics.
- Vegan and allergy-friendly: Gluten-free, GMO-free and free from common allergens, making it a versatile choice.
- Convenient format: Easy-to-take capsules that fit seamlessly into your daily routine, whether you are at home, at work or travelling.
Use & dosage
The recommended dose is one capsule daily, which can be taken with water at any time of day. The product can be combined with other food supplements, such as vitamins or minerals, as needed, but it is always advisable to consult a doctor if you are unsure. As EpiCor® is stable and does not require special storage conditions, it is easy to maintain the routine while travelling.
Quality & manufacturing
Doctor's Best is known for prioritising quality and safety at every stage. Products are manufactured in modern facilities that follow strict GMP (Good Manufacturing Practice) guidelines to ensure purity and accurate dosing. EpiCor® is a patented ingredient with a documented manufacturing process, and every batch undergoes rigorous testing to ensure it is free from GMOs and gluten. The packaging is designed to preserve the product's stability and shelf life, providing a supplement you can rely on day after day.
