What is a potential risk of over-supplementation in MNT?

Over-supplementation in Medical Nutrition Therapy can lead to toxicity or nutrient imbalances. This occurs when excessive amounts of certain vitamins, minerals, or other supplements are consumed, surpassing the body's requirements. For instance, fat-soluble vitamins like A, D, E, and K can accumulate in the body and potentially cause harm, leading to symptoms ranging from mild discomfort to severe health issues.

Furthermore, taking high doses of specific nutrients can interfere with the absorption or metabolism of other nutrients, potentially leading to deficiencies or health complications. When nutrients are out of balance, it can impact various bodily functions, including hormonal regulation, nerve function, and even metabolic processes.

The other options do not capture the significant concerns associated with over-supplementation. Increased appetite might occur due to other factors but is not a primary concern of over-supplementation. Enhanced nutrient absorption is generally desirable and would not be a consequence of taking too many supplements. Improved mental clarity is often a goal of proper nutrition; however, excessive supplementation may actually detract from cognitive function due to toxicity or imbalance. Therefore, the emphasis on toxicity and nutrient imbalances reflects the most critical risk associated with over-supplementation.
