Natural Color Variation: O.N.E. Multivitamin is a light yellow powder with dark speckles, and does have a distinct odor/taste. The odor/taste is due to the selenium and choline. Methylcobalamin, which is naturally darker in color, can cause a light pink to dark red speckled look to the product. The smallest amount of moisture will accelerate blooming of the B12, which can cause more of a spotted appearance. These observations are characteristic for this product, and it is safe to use.*
