I definitely notice that when I use the lion's mane elixir, I have more focus. However, the flavor is very earthy, so there are only a few things I like to mix it with. It is great in coffee, but I would avoid adding it to fruity or floral teas or smoothies.

I’m a major skeptic, but at really do think this stuff helped me with energy and focus in my work. There’s definitely a mushroom smell, but it’s pretty well balanced by the herbs and stevia. Will definitely order more.

This is a nice alternative to coffee in the morning. I enjoyed mixing it with tulsi tea for an energizing herbal concoction.
