Storage of Probiotics:
Are you worried about the necessary storage conditions for probiotics, such as selling them from a regular shelf versus selling them from a refrigerator? Or shipping them in a regular box versus in a cold box?
Endurance in the Stomach
Have you seen advertisements for probiotics that can endure the acidic conditions of the stomach?
Encapsulation is a technique that helps increase the viability of probiotic bacteria from harsh environments, such as low pH levels in the stomach, temperature, and humidity. There is a wide variety of such coating materials. The viability of probiotics depend largely on the type and concentration of such materials. However, there are not many studies readily available to evaluate which method, brand, and product are the best (1).
Dead Probiotics are Also Effective
There are some surprising reports that even dead probiotics have beneficial effects on the host, just like how a "killed" polio virus can affect immunity (2, 3). Dead, or killed, bacteria have particular protein biomarkers in their cell membranes. The biomarkers can elicit a response in our body. Therefore, the statement that probiotics must always be alive could be wrong.
Not Worth it to Buy Coated Probiotics
Therefore, it could be a waste of money to buy expensive, coated probiotics. Instead, t is more important to concentrate on the probiotic strains.
