There's no significant difference between mushroom powder and mushroom capsules. Mushroom powder tends to be a little less expensive, as the extra step of putting the powder into capsules is not required. However, some consider mushroom powder inconvenient, as it needs to be mixed into food or drinks in a sanitary setting. Mushroom capsules, while a bit pricier, offer a lot of flexibility for someone with a fast-paced lifestyle. I take a big shot glass of vitamins and supplements before bed each night, including mushroom extract capsules. Choose the product that's best for your lifestyle, and rest assured– if it's one of the products on this list, you are enjoying a world class mushroom extract optimized for potency, purity, and quality.
