What are Mushroom Supplements?

Most people blend the powder in hot water to drink straight, although you can also add it to soup, smoothies, oatmeal, and other foods, just like a plant based protein powder. Some even use mushroom powders as a healthy energy drink to replace their morning coffee.
These supplements aim to provide the maximum benefits of adaptogenic mushrooms in a highly concentrated form. Many of the varieties may offer health benefits ranging from increased energy and better athletic performance to cognitive enhancement and more. Certain mushroom supplements can work like supplements to boost your immune system and help you fight off infections.

ONNIT supplements aren't designed for everyday use like the others on this list. Instead, you'll take up to four capsules before an intense workout, taking care not to consume more than six within 24 hours.
The Research on Mushroom Supplements
While mushrooms have long enjoyed culinary prominence, they are gaining attention globally for their medicinal benefits. Mushrooms are low in calories, relatively high in protein and fiber, and considered rich sources of essential B vitamins, potassium, copper, and selenium.
Each variety of mushroom typically included in supplements offers distinct health benefits. For example, lion's mane mushrooms are purported to fight off the effects of inflammation to support immune system function, especially for the intestines. The fungus also shows promise for treating anxiety and depression. One study found that women who ate cookies containing lion's mane extract reported less irritation and stress than the control group.
Cordyceps mushrooms are linked to better athletic performance. They increase the body's production of adenosine triphosphate (ATP) for more efficient oxygen usage so you can go longer before getting exhausted. Early evidence shows their antioxidant content might mean they fight symptoms of aging by improving memory and sexual function, and they may even help manage type 2 diabetes by decreasing blood sugar levels.
Finally, reishi mushrooms show promise for their anti-cancer properties. The fungus has effectively killed off cancer cells within a lab setting, and preliminary research found that a year of treatment with reishi shrunk the size and number of tumors within the large intestine. These results, however, are very early and further study is needed to evaluate the effectiveness of these mushrooms for treatment of any disease.
How to Choose the Right Mushroom Supplement
When shopping for the best mushroom supplement, there are critical pieces of information you should seek out. Here's our advice for how to compare brands to find the best product for you.
Some mushroom powders contain only one variety, while others include up to ten types per serving. Mushrooms aren't interchangeable, so make sure you know which ones you'll be ingesting so you can determine whether they offer the right benefits for your situation.
Many mushroom supplement brands have undergone third-party lab testing for purity and safety. Look for signs on the packaging that the brand has invested in proving it contains what it claims.
Mushrooms in supplements are sourced from around the world, and some regions are more reliable than others. It's best to look for supplements that contain mushrooms grown in the United States, and preferably organically.
Look at the nutrition facts to determine how much powdered mushroom is actually contained within each serving and how many scoops or pills you need to take per dose. Some require you to take up to eight mushroom capsules per day—which may be more than you want to deal with.
Some mushroom supplements contain artificial flavors, colors, binding ingredients, and other compounds you don't want to ingest. Scan the ingredients list to ensure nothing has snuck into the formula.
How To Use Mushroom Supplements
Most mushroom supplements come in one of two forms. They are either powdered or encapsulated.
You can treat mushroom powder similar to instant coffee or collagen supplements. Simply add the powder as directed to hot water (or your beverage of choice) for a health boost. As most mushroom powders are caffeine-free, you can take them at any time of day. However, some people may have stomach sensitivities that make them better on an empty stomach.
Encapsulated mushroom powder should be taken just like other dietary supplements. Note that most brands suggest taking multiple capsules multiple times per day for full benefits.
Safety and Side Effects
As with most natural supplements, there are certain risks associated with mushroom powder.
Most are considered safe at the recommended doses. However, some, such as reishi, may lead to side effects like dizziness, dry mouth, nausea, and other digestive issues. In addition, formulations that contain ashwagandha may trigger iron retention, so those with hyperthyroidism or Grave's disease should avoid them. Finally, cordyceps mushrooms are linked to mild side effects like diarrhea and constipation after regular use for some people.
As always, those who are pregnant or nursing or who have preexisting health concerns should talk with their doctor before taking any mushroom extract supplement.
Mushroom powders offer a potent dose of beneficial compounds that may help your body function at its best. However, these products aren't the magic elixirs their manufacturers might claim. Keep your expectations realistic and take them as directed, and you may soon notice improvements in your energy levels and overall mood each day.
