I've been using this for several months. It's perfect for an after lunch drink to combat the tiredness. The taste is very smooth and lightly sweet.

I’ve been using Four Sigmatic products for a while and this is one of my favs. It’s great to stir into coffee or a smoothie for an added boost of focus, or you can mix the elixir with some hot water for a pick me up during the day

Husband has fibromyalgia. So sometimes he gets the "Fibro Fog". These helps to focus him, and he says it tastes pretty good. Like a very earthy tea.
