Peruvians have eaten maca root for thousands of years without incident, so it can be assumed that the food is safe to consume. However, it's important to note that residents of the Andes eat maca root as a regional crop that's a staple of their diets.
The maca root supplement you purchase online or at a local health store will likely be in capsule or powder form. Therefore, it's impossible to know what all occurred during processing. With any supplement, there's always the possibility that impurities or inappropriate amounts of the plant made their way into the final product.
The U.S. Food and Drug Administration (FDA) doesn't regulate supplements, so it's best to be cautious. There are a couple of ways you can do this. For starters, always talk to your physician about taking a supplement -- whether it's maca root or something else. The next thing you should do is make sure you buy supplements from reputable brands and dealers.
Wondering about just cutting out the middle man and growing your own maca root? That's probably not going to happen. There's a reason why maca root is exclusive to the Andes region. It grows only in cold, high-elevation areas with poor soil quality.
