Which statement is true about nutrition labels on supplements?

The correct answer highlights an important aspect of nutrition labels on supplements. Unlike food labels, which must adhere to strict regulations that require complete disclosure of ingredients, supplements can sometimes be less transparent. This is often due to the nature of the dietary supplement industry, where manufacturers may not be mandated to list every single ingredient or the precise quantities of certain components. This can include proprietary blends, where the total amount of the blend is provided, but individual ingredient amounts are not specified.

This lack of complete ingredient disclosure can pose challenges for consumers who rely on labels to make informed choices about their nutritional intake. This is why it is essential for consumers to do further research or consult health professionals when selecting supplements, as the labels may not provide full clarity on what is actually in the product.

In contrast, while some items on nutrition labels may be verified by independent organizations, this is not a universal requirement for all supplements. The FDA does not standardize all supplement labels to the same extent as food labels either, which can lead to inconsistencies across products. Hence, option C stands out as the most accurate statement regarding nutrition labels on supplements.
