Four Sigma Foods

(24 products)

Four Sigma Foods blends functional mushrooms — reishi, cordyceps, chaga — with coffee, chai and standalone elixir sachets, alongside adaptogen blends featuring ashwagandha and eleuthero.

Some products in the range are high in caffeine (such as the Boost High Caf Coffee), so those sensitive to caffeine, pregnant, or trying to limit intake should check the label.
