The probiotic I am taking looks pink. Does this mean it is spoiled or no longer "active"?
The probiotic material in powders, capsules and tablets is usually white or off-white. However, some probiotic strains can interact with preservatives used in a supplement, resulting in a pink color, which is not harmful and does not indicate that the probiotic is spoiled or inactive.
