I have just now returned to using your ALL ONE Active Seniors supplement product from a composite can opened years ago. The ‘used by’ date on the bottom is 4-20-2012.
The odor of the product is offensive, and I have been trying different liquids to mask the very unpleasant taste. It could have picked up the disagreeable taste while stored under the bathroom sink all these years.
My question is: Is this odor/taste a normal problem? Could there be a reason to discard the remaining product? Or, do you suspect that this product is OK to use?
The Vitamin Professor Responds:
The best place to store ALL ONE is in a cool dry place like a kitchen pantry.
When the product is stored (especially after being open) it in a bathroom where there may be steam and moisture condensation is discouraged.
The ‘offensive odor’ is most likely from the fact that moisture and temperature changes cause the B vitamins / Vitamin A as well as other nutritional components (vitamins & minerals) to begin to break down. This process gives off the unpleasant aroma. This is normal when the product has been stored in a bathroom for example.
All that being said, and the fact that the product is passed the expiration date, I would recommend disposing of that container and purchasing a new one.
All the best,
