The nutritional value of such ingredients can degrade when exposed. Therefore, maintaining the viability (and consistency — along with accurate label claims) of these nutritional components in food and beverage products, from the time of production to the time of consumption, can be challenging.
Although there is a risk of products providing lower levels of vitamin or other nutrients (compared with the promises made on their labels) in some cases, there is also a risk of consumers actually consuming more of certain nutrients than they were aware of, or desired to consume.
Knowing that there will be degradation, some manufacturers “over-fortify” products to exceed label claims by the time the products get to (or sit on) shelves.1
As a result, end-users sometimes consume products with nutritional ingredient levels that actually exceed the claims made on labels. Consuming excessive doses of certain vitamins and other ingredients can be harmful and, at a minimum, they simply deserve accurate and honest labelling of the products they ingest.
