But shopping for a new supplement, especially one like a greens powder, can be overwhelming because there are so many kinds, with lots of variation in the formulas and ingredients. Not to mention, it’s important to know that not all greens powders are as good for the environment as others. “The ones that seem to be the biggest deal these days are the organophosphates, which are just a kind of pesticide,” explained Rountree. “It has been shown that if you put kids on an organic vegetable diet1 and you measure organophosphates in their urine, within three days, the levels dropped by something like 90%.” And in addition to being a smarter choice for your body, choosing organic can be a healthier option for the environment as well. Organic farming can reduce pollution, conserve water, and use less energy overall. “They’re very high in nutrients,” said Rountree. “They have a particular type of polysaccharide in them that actually binds to heavy metals and toxins.” We are inundated with these toxic chemical compounds called organochlorines, Rountree explained. Our bodies are doing their best to get rid of them and the sea veggies help bind to these chemicals, which in turn helps our body eliminate them.* Nori, a type of seaweed, has been shown to bind to dioxin2, an organochlorine. It’s also important to note that, because sea veggies are so naturally absorbent, it’s essential to opt for organic sea veggies that are grown in a clean, controlled environment. “I want to see some digestive enzymes to help me break down my food,”* Rountree said of shopping for an effective option. “I also want to see some pre- and probiotics.” Once you get your hands on a top-of-the-line greens powder, it’s easy to find a variety of ways to incorporate it into your daily habits. Rountree’s personal practice? “I make a smoothie,” he said. “This is something I’ve recommended to my patients for years.”
