I didn’t see “Refrigerate after opening” on ARG Solution of Magnesium (or on Selenium Solution), so I have not refrigerated it. Is it still potent and safe to take?
Being left unrefrigerated will not adversely affect the potency of these products. These formulas have a low concentration preservative to shift the pH of the solution to deter microbial growth. We suggest refrigerating them after opening to further deter any microbial growth that may be introduced into the product during opening and use of the products.
It is not possible to predict how long any product will continue to resist microbial contamination if left unrefrigerated, as it depends on many factors, including how it is handled during use. Under conditions of normal, careful use, there is no reason to expect that room temperature storage for several days would adversely affect the product.
