Answer:

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. For more information, see the ConsumerTips section of the Probiotic Supplements Review.
