What qualifies a vitamin dosage as a megadose?

A vitamin dosage is classified as a megadose when it significantly exceeds the recommended dietary allowance (RDA) for that vitamin. Generally, a megadose can range from 10 to 100 times greater than the RDA, depending on the vitamin in question and its specific health implications. The primary characteristic that defines a megadose is not just a slight increase, but rather a vast and often excessive intake that could lead to potential health risks or toxicity.

Taking vitamins in liquid form, over extended periods, or having an intake less than five times the RDA does not inherently qualify as a megadose. Thus, the emphasis on "vastly exceeding" the RDA encapsulates the essence of what constitutes a megadose, making it crucial for assessing nutritional adequacy and addressing potential overconsumption risks.
