Only two strains of probiotics are shelf-stable, whereas different and diverse strains can be present in refrigerated probiotics. But shelf-stable probiotics have the advantage that they can be used in other food products, like granolas, butter, soups, etc. Just don’t mess with the packaging or open blister packs until you want to use them, as they are packed for preservation. Dead probiotics won’t harm you, but they don’t have any health benefits either. 

According to a recent paper published in the European Journal of Nutrition, vitamins and other nutrients play a crucial role in metabolism — the process in the body that supports overall health. How vitamins and phytonutrients interact with prescription medications can impact metabolism. In one example, antacid medications can interfere with vitamin B12 and calcium absorption, so requirements for these and other nutrients may increase, yet people don’t make the adjustment in their supplement plans.
