According to the dictionary, adaptogens are an herbal medicine derived from certain plants and fungi that help the body adapt to stress, but this doesn't really provide the whole story. When we get stressed our cortisol levels rise, triggering the "famous flight or fight" response. Cortisol is important, as it give us energy when we're stressed or exercising, but if there is an excess of the hormone, it can contribute to weight gain and high blood pressure. Chronic stress, one of the main culprits behind high cortisol, has been tied to a number of issues including anxiety, fatigue, and sleep loss. While the science behind adaptogens isn't 100% clear, there is a strong contingent of loyal users who swear by these natural products and their abilities to combat the effects of high cortisol. Since adaptogens are dietary supplements, the FDA doesn't play a very active role in regulating them. This means there's a pretty high rate of fraudulent marketing in the field. Still, peddlers and users alike will rabidly defend the health benefits of taking these natural stress reducers.

Part of the appeal of adaptogens is that they have deep roots, using Chinese and Ayurvedic herbs, medicines that have been around for thousands of years. Unfortunately, these deep roots don't mean much in terms of flavor. According to Jack Latner, owner of Lifehouse Elixirs and Tonic Cafe in Los Angeles, "99.9% of [these herbs] taste horrible on their own." The herbs also have tough-to-pronounce names like astragalus and ashwagandha, which according Latner makes them slightly unapproachable to newcomers. Latner focuses on creating beautifully colored, adaptogen-infused smoothies to get customers to come into his shop.

Latner's commitment to making adaptogens more accessible has been derided by some however. Many nutritionists believe that these supplements need to be consumed consistently, and that occasionally having them in smoothies or other beverages is unlikely to have any effect. The idea is that these products need to be treated like a form of regular self-care. The real question, however, is do these supplements actually work?

Nearly 68% of the population uses some kind of dietary supplement, despite the fact that most supplements aren't tested in a controlled environment. Instead of performing tests comparing effects against those of a placebo, most newsworthy studies surrounding supplements are purely observational. That is to say, there isn't much evidence to support their purported health benefits. Still, possibly due to sensationalist headlines, the market for dietary supplements is estimated to hit $278 billion by 2024. While there is plenty of evidence to suggest that Americans don't get enough nutrition through food, it's still unclear whether or not supplements are the answer to this problem.

All that in mind, as a niche segment of the reasonably suspect supplement industry, adaptogens actually seem to be effective. They've been studied extensively since World War II, most notably by scientists in the USSR, and while some of their effects have been exaggerated, there are studies that indicate that adaptogens, particularly the plant Rhodiola Rosea, can reduce fatigue and increase a subject's ability to pay attention after being administered regularly over a four-week span. Unlike many supplement tests, the testing of Rhodiola Rosea was done in a placebo-controlled setting.

It's important not to take the results of single study as an unfailing endorsement, but as it stands, it can be argued that at least some adaptogens are effective. That said, the lack of FDA regulation should give potential consumers pause. While it has been discovered that most adaptogens are innocuous, it's worth thoroughly researching the exact supplement you want to take before going out and buy some. These supplements probably won't do any bodily harm, as studies show they're safe for human consumption, but, as with anything, studying up on adaptogens before buying them is a good idea.
